Is your home a 100 megabit or gigabit light cat？ Dry goods, culture and education, you can change it yourself+layout Wi

foreword

Guangmao, since fttp, this is the gateway for every household to access the Internet. But not many people pay attention to it.

This paper mainly talks about a simple way to change the light cat, based on the principle that you can not get telecomadmin, and you can not brush mac.

In fact, for many families in fttp, their light cats are older, and all LAN ports are only 100 megabytes. This has caused many users to pay 200M optical fiber, and actually enjoy 90M broadband, but they can’t enjoy the use feeling brought by speed increase. Even if 100Mb/S optical fiber (equivalent to computer display value of 12.5MB/S), and 100 MB port, only about 90M optical fiber downlink rate (equivalent to 11.25MB/S), so the old 100 MB optical cat has become a bottleneck for users.

The state requires operators to speed up and reduce fees. At present, most families upgrade to 100 M optical fiber for free, and there are not a few 200M optical fibers. Developed areas are already laying out 500-1000M, which is believed to gradually spread to tens of thousands. Therefore, the replacement of gigabit light cats is a problem that every household will face sooner or later. I have tossed a light cat many times, and I will share my experience with my friends and myself. Four methods range from simple to complex:

Finally, it is not recommended to buy old light cats. Electronic components such as optical modules and CPU of light cats have a long life, and the failure rate of second-hand light cats will be higher. When something goes wrong with the light cat, you will be crazy (especially for netizens with poor foundation).

When recommending a wireless router, I choose the one I have used and think it is good. If I haven’t used it, I dare not talk nonsense … My principles for choosing a router are: 1. Stability. 2. The performance is quite good. 3. When the signal strength is sufficient, choose the router that meets the national SRRC low radiation standard.

Method of replacing light cat 1 — — Replace the rented light cat

Scope of application and evaluation of methods:

Applicable object: Telecom/Netcom and other operators rent light cats to you.

How easy it is to change a light cat: simple

Recommended degree: 5 stars

Degree of expenditure: only due to the region.

Disadvantages: Need patience to communicate with customer service and technicians, and even need to use unconventional means.

Replacement steps

　

▲ First of all, first confirm that your light cat is a 100-megabit light cat? Everyone’s model varies from person to person, but the nameplate on the back of the light cat will not deceive people. Look through the nameplate on the back of the light cat and find out the model. Is this light cat a 100-megabit light cat or a gigabit light cat under Baidu? Huawei HG8245C like me is a 100-megabit light cat.

If you are a 100M/200M optical fiber user, you can call the optical fiber communication operator, of course, you should report your broadband account number, and the opposite manual customer service may verify the personal information of the householder. After the customer service confirmed that it was correct, we declared to the human customer service that we used the speed measuring software to measure it, but it did not reach the nominal fiber speed. I just looked at the nameplate on the back of the light cat and found that it was a 100-megabit light cat. My light cat was rented from you. Could you help me replace it with a gigabit light cat?

The key points you need to consult later: whether it costs to replace the rented light cat, what conditions are needed, and when will an outside technician contact you. Generally, the rental is to replace the Gigabit light cat for free.

The rest you just need to wait for the technician to come to your door and ask him to help you replace the Gigabit light cat, and you just need to stand by and provide corresponding assistance to the technician in time (basically no assistance).

Method of replacing light cat 2 — — Rang telecom daigou guangmao

summarize

Applicable object: Except all optical fiber users who rent optical cats.

How easy it is to change a light cat: simple

Recommended degree: 5 stars

Spending degree: slightly higher, the cost varies from region to region, but there are matching discounts. For example, in Xiamen, the cheapest light cat is paid 279 yuan in one lump sum, and Xiamen Telecom will refund the phone bill to 240 yuan in 24 months.

Disadvantages: the quality of light cats is average.

Replacement steps

Call the optical fiber communication service provider, contact the human customer service, and then verify the identity. Explain to the customer service that you bought your own 100-megabit optical cat and want to replace it. Do you provide the service of purchasing and replacing optical cats? Customer service will generally say yes, and then check the quotation sheet of light cat.

At this time, you need to ask if there are any matching discounts. If there are, you can consider whether to replace the light cat (after all, the phone bill deduction varies from person to person and from region to region). If you are interested, you can register with customer service, and an outside staff member will contact you and come to replace the light cat within 3 working days.

The rest is the same as before. The disadvantage is that the quality of light cats is average.

Method of replacing light cat 3 — — Taobao/Tmall self-purchased area limited light cats

Method evaluation

Applicable object: In addition to renting all optical fiber users of Light Cat, we are also pursuing the brand and quality of Light Cat.

How easy it is to change a light cat: It can be as simple as it is to look at the face.

Recommended degree: 3 stars

Cost: 150~250 yuan.

Disadvantages: there is no discount on the overall expenditure. If Loid is successful, it will be very smooth. If Loid is in trouble, it needs to be tossed. Light cat bridging/dialing settings need to be configured by yourself.

Point: Be sure to buy a brand new one! Be sure to buy a brand new one! Be sure to buy a brand new one, and it was made in the last 12 months.

Replacement steps

I asked our outside customer service manager before, and I asked him if you bought Huawei light cats. The manager saidno. What about ZTE? The manager also answered no. What about the bonfire? I didn’t have ………., and then I said what brand. I forgot … In the field of optical communication, Huawei is the strongest in China, followed by ZTE. Huawei uses Huawei, which can make the light cat more stable, and basically does not need to restart. Of course, Huawei’s light cat is also more expensive.

▲ First of all, of course, go to Tmall/Taobao to buy your favorite big brand light cat. Remember to confirm whether it is EPON or GPON. For example, I bought Huawei’s customized version of Fujian Telecom HS8145C (EPON). You can save a lot of trouble if you buy a custom-made light cat from the communication operator where you belong.

▲ Before the light cat arrives, you must first write down your Loid and password (both of them can be copied, copied into txt, stored in sections, and then copied). This is the key.

▲ Only one port of ▲HS8145C is Gigabit, and the rest are 100 megabits. The location of the specific Gigabit port will be different due to different models. Please ask the seller. If there is a wireless router, let the wireless router occupy the Gigabit port first. In the initial setting, our computer only needs to access the 100 Gigabit port. If the optical cat is directly connected to the PC, let the main PC directly connect to the Gigabit port. Then remove the protective sleeve of the optical fiber port and plug in the optical fiber (never break the optical fiber), plug in the telephone with a telephone and plug in the itv with an itv. Remember to take a photo of the nameplate of the new light cat, which will be needed later.

▲ Open the browser, enter 192.168.1.1 in the address bar (this is usually the case for light cats, if you are not clear, you can consult the seller), and then you will enter the light cat registration and certification page. Then enter/paste the Loid and password you recorded before. Then click OK, and you can get Loid.

Loid will encounter three situations.

▲ Situation 1: Very smooth, the whole process is very fast, about 20~60 seconds, the light cat registered successfully, and downloaded the settings from the server. If you encounter this situation, you will be very comfortable and you can watch the final steps.

▲ Situation 2: It gets stuck during the registration process. Personally, don’t move, wait for the light cat to end automatically. After about 600 seconds, either the registration is successful and distributed, or the registration fails and the Loid is renewed.

▲ In case 3, during the registration process, "The terminal has been registered on the ITMS platform, please find the support manager to handle it and re-register." What you have to do at this time is to call the customer service phone of the communication operator or the technician/account manager of this community. I told the customer service/technician/account manager that I bought a customized version of the light cat in my own area and was replacing it. I asked for technical support. If it is customer service, it will help you register your phone number and place an order with the technician. After receiving the reply, you should generally provide your own LOID or broadband account at this time, and provide the last 6 machine codes of the light cat.

Of course, the technician will add your WeChat, please provide some information about the light cat LOID and tell you what you know.

Under normal circumstances, the technician will ask you to re-LOid and keep it, then contact some support to help you solve the problem, and then you can generally get rid of LOid and download the configuration successfully. Light cat registered successfully.

If it doesn’t work, it’s estimated that the technicians will come to the door, hahahahahaha. To be honest, the technicians of broadband operators have a very good attitude. If they are installed on the same day and repaired on the same day, they will usually help you solve it for free. Remember to be nice to the technicians/customer service. After all, they don’t smile at people. After all, people also work to make money.

If you want to be quick, you can try to contact a little support, but to be honest, without relevant query software, you can’t find out where the problem card is and whether the light cat is connected to the outside line. I recommend letting technicians help you remotely.

Follow-up setting of light cat configuration

▲ After getting the distributed data correctly, we need to enter 192.168.1.1 in the browser (if it is not this, it is behind the nameplate), and then we will see this interface, and we will find the — — Quick maintenance entrance, and then enter the account password behind the nameplate, you can enter the maintenance entrance of Guangmao.

▲ After we refresh for a while, we can see the various states of the light cat. If we are experts, we can capture a lot of information on this page.

▲ Then, manually configure the dialing mode of the optical cat. If there is a wireless router, select the bridging mode. If it is directly connected to the computer, select the optical cat to dial. You can only choose one of the above two situations. If you forget what dialing method you are, you can consult a technician. For example, if we want to dial by bridge in Xiamen, we need to switch to bridge mode+light cat bridge+router dial in the computer room. Please consult the customer service or technician for the situation in each place.

▲ Then choose whether to turn on the wireless WiFi of Guangmao. If only one person uses it or the budget is insufficient, you can choose to use the WiFi of Guangmao, and then set the WiFi name and password. However, the WiFi of the optical cat is only 2.4G band, and the rate is generally 300Mb/S (equivalent to 37.5MB/S on the computer side, and any wireless network card will eat up the wireless bandwidth), which will increase the burden of the optical cat and shorten its service life. I have a wireless router at the back end, so I choose to turn off the WiFi of the optical cat here to reduce radiation and interference, and at the same time move the dialing to the wireless router AC86U, so that the optical cat can only do the bridging function, so that it can basically support the 10 Gigabit optical cat+10 Gigabit router.

▲ Then you can choose whether to change the password of the light cat. If you need to change the login password of the light cat, you must tick the red arrow. Personal recommendation changes to improve security. What? Are you afraid to forget? Don’t be afraid, consult the seller or the technician, they can help you find the password, and their software+equipment is miraculous.

▲ Finally, the change interface will be displayed. Click OK to make all the settings before taking effect.

▲ Click the "Status" tab in the red box in turn — — "User side information" — — "Ethernet Interface Information" should confirm whether Gigabit port is used by wireless router or main computer. For example, my gigabit port is used by wireless routers.

▲ Another very important thing to note is to click on the red box "Network" tab. At this time, we need to remember the initial ip distribution and the termination of ip distribution. This is very important for computers that can’t connect automatically or the wireless router settings at the back end! ! ! Remember it, or take a screenshot.

▲ The router ip should fall within the IP distribution range of the optical cat, otherwise the router can’t bridge the dialing, and we can’t access the Internet. Remember! ! ! ! Then click Apply this interface setting.

This concludes method 3.

Method of replacing light cat 4 — — Command+firmware bottom modification for second-hand optical cats

pay attention to

This method has a high threshold, is very difficult, takes the most time, and needs to be tried many times. Personally, this method is highly recommended, and it doesn’t save much money, and it also bears the pressure when family members can’t get online. But I’d better show others this method. It will take at least 2~6 hours to modify this method. I will change, but I don’t want to do this. Wouldn’t it be better to spend that time with my family? )

Finally, it is not recommended to buy old ones. The optical module, CPU and other electronic components of the optical cat have a long life. When something goes wrong with the optical cat, you will be crazy (especially for netizens with poor foundation).

Home wireless network layout — — Insufficient budget

▲ If the budget is insufficient, if you don’t consider buying a router for the time being, start using the WiFi of the optical cat first, but I think this is only temporary, because the most important function of the optical cat is photoelectric conversion, and that WiFi is only 300M, just a wireless network card will be eaten up, and it will increase the burden on the optical cat. Moreover, the cheap light cat only has a single gigabit. If you want 4 Gigabits and need to increase the budget, you might as well buy a wireless router directly. Moreover, there are many signals in 2.4G, and the interference is very serious, so it is easy to cause disconnection due to interference.

I installed the wireless router below 300 yuan for my relatives.

Seriously, I only consider two routers, one is ASUS and the other is Netware. Although the 3G of Xiaomi router is very cost-effective, the stability of Xiaomi router depends on its face, and the two Gigabit LAN ports have not passed the national mandatory standard SRRC certification. Some netizens responded that they frequently dropped the line during use.

▲SRRC is a national mandatory standard, which is more in line with national conditions.

▲ I installed this RT-AC1200GU for my relative before, and I told him that the stability, four gigabit ports and proper signal strength are worth the 100 yuan price difference. After all, it has passed the SRRC standard and is more secure. Four Gigabit ports are more scalable and can be used on nas/PS4 and other devices. Moreover, there is a 2.4G+5G dual band, which allows the notebook to connect with 5G signals and enjoy faster speed.

Moreover, ASUS’s UI interface is refreshing, simple and intuitive, with many interesting functions.

Two 450~500 yuan routers I used.

One is RH17 of the Qualcomm scheme, and the other is the middle-end explosion king — — Broadcom scheme 66UB1.

▲ In contrast, RH17 is cheap, with a theoretical maximum speed of 400M+1733M, and supports Qualcomm mu-mimo. Each WiFi has an independent WiFi processor, but there is no Merlin firmware. But there is no problem in the use of ordinary families. In terms of overweight load, 66UB1 is more compressive than RH17.

My RH17 was finally taken by my friend. My friend’s former friend router was very unstable, and dropped calls and dropped packets frequently. My friend’s older sister always yelled at my friend. The friend himself said, "Since the router was changed, his elder sister didn’t yell at him. The signal was good and the laptop was connected quickly, which was very worthwhile."

▲66UB1, the mid-range explosion king, is very practical, with merlin, low fever, very stable performance and very affordable price. I believe netizens also highly recommend this model.

I just started RT-AC86U+ USB-AC68 recently.

66UB1 is a very cost-effective router, and it was my main router. However, my relative’s router was broken, and his family needed a higher-performance router, so he took my 66UB1 away. When buying a router, I updated and iterated RT-AC86U for these devices, considering that my family has recently acquired a lot of high-throughput wireless devices.

▲RT-AC86U, now JD.COM only needs 799, which is very good value. After passing the SRRC low radiation certification, Broadcom dual-core 1.8G will bring better wireless network control.

▲ The signal coverage capacity of ▲AC86U can cover approximately 120 ~ 130m2 under the SRRC national standard. Supporting AiRadar signal concentration technology will make WiFi more stable and faster. The maximum support is 1024qam (2.4g) 750mb/s 1024qam (5g) 2167mb/s.

▲ Classic red and black color scheme, AC86U. I like it very much. It is a vertical router and stands stably, which can save ground space.

▲ Three separate antennas, which can be hemispherical at the top.

▲ Just plug the antenna into these three antenna ports, and the whole router is still quite high in height.

▲ There is a WiFi switch button and a WPS button on the right side of the router.

▲ The vertical router has an advantage, that is, it is very convenient to connect/unplug the USB power cord and network cable, and at the same time, the vertical router can also have quite good heat dissipation space.

▲ There is a reset/restart button at the top of the left, a power button, a power socket, a USB 2.0 USB 3.0 interface, and a blue WAN port, with an LED light control button in the middle and an acrylic ASUS LOGO at the bottom.

▲ On the right side are four Gigabit LAN ports, marked with yellow.

▲ The indicator light at the bottom of the front of the ▲86U is white in normal operation, turned off when not in use, and red in case of failure.

▲ There is a large rubber anti-slip sticker at the bottom, which can make the 86U stand stably.

▲ A transformer with an output voltage of 19V, an output current of 1.75A and an output power of 33.25W

▲AC86U also supports MU-MIMO of Broadcom scheme. When multiple Broadcom mu-mimo devices are connected to 86U at the same time, the throughput will be parallel, reducing the delay of each device and improving the effect and speed of WiFi access.

▲ ASUS USB-AC68 is a USB3.0 mobile network card, which can access one of 2.4G or 5G WiFi signals, support transmission speed of 600+1300 Mb/s, and support mu-mimo of Broadcom scheme.

▲ Compared with the AC1900 network card of pci-e, the USB network card has the advantages of no need to shut down, plug and play after installing the driver, and also supports notebook expansion. 600+1300Mbps, if the light is seen from the transmission speed of 5G, it can already surpass the wired transmission of Gigabit LAN.

▲ Accessories list

▲ Plug in the USB protective cover and fold the antenna. The whole USB-AC68 can be held in the palm of your hand.

▲ Open the top two antennas decorated with red Maya patterns, which is the signature style of AC68. There are two built-in antennas inside the Maya pattern in the middle, and there are four antennas in AC68U.

▲ All adopt USB3.0 Type A interface, and there will be no bottleneck in transmission speed.

▲ After the assembly, this is the signature action.

▲ Come on, let’s just say that we don’t practice the fake style and serve food.

My wireless network settings

▲ Generally speaking, when a new router arrives, it needs to be initialized. I use the optical cat bridge dialing and dial at AC86U. The optical cat’s WiFi is turned off, and the optical cat is only used for photoelectric conversion+bridging, which can liberate the optical cat to the greatest extent and prolong its life. Then set 2.4G and 5G separately to form two independent signals. Of course, it is also possible not to separate. AC86U supports automatic switching signal technology and can be automatically allocated by itself.

▲ After setting, enter the main interface, and the status of the whole router can be seen at a glance. ….. Wait, I don’t think I connected the NAS. I’ll get the NAS.

One more thing, Merlin firmware is not suitable for everyone. For many people, ASUS official firmware is the best, because it is stable, fully functional, and the UI is simple and easy to use. Merlin is just like ASUS firmware.

▲ ASUS RT routers of models above ▲66ub1 all have their own intelligent network guards, which provide router-level security protection for home networks. I put these security protection measures on the 86U.

▲ Network security guards also provide webpage and APP filtering functions, which can filter the content of the mobile phone/computer used by children and then open it to him at the right time.

▲ After the ▲QOS function is turned on, broadband can be intelligently allocated under the condition of heavy load such as download/intranet transmission of a certain device, and the impact on other online devices is reduced.

▲ Traffic analysis has little effect on the broadband monthly subscription in China. It is very useful for foreign countries, such as Australia, to charge by flow. (Of course, it will be useful if you use a charging network card.)

▲ The game acceleration function is a special function of routers above AC86U, which can enjoy the acceleration function between different servers around the world.

▲ Users of ASUS routers can register for free and use the game acceleration service for free.

▲ If you want to access your own USB device connected to the router on the external network or wake up the computer remotely, you can turn these two functions on.

▲ If you want to turn off 2.4G and 5G intelligent network selection, you can turn off the Smart Connect function in the wireless network interface, and ASUS routers are also optimized for Xbox users.

▲ For example, if I use the optical cat bridge, and the optical cat is only used as a photoelectric conversion device, I only need to select the PPPoE connection type in the external network (wan) interface, enter the broadband account number and password, and then apply the interface settings to realize automatic dialing.

▲ In the wireless network and professional setting interface, the signal can be set and the area can be switched, but it is not recommended for individuals to switch to the United States and Australia with strong signals, because the radiation is slightly large, and long-term use is afraid of affecting health.

▲ In the system management interface, you can choose the working mode of the router. Generally speaking, it is the default. If there is an ASUS RT router that has been eliminated by updating iteration, you can turn on AiMesh and let your RT router simply be an AiMesh device.

Mesh — — > 802.11ac + MU-MIMO

AiMesh — — > ASUS expands its own firmware, so that ordinary independent RT series routers can support and join the function of Mesh network, so there is no need to buy a complete set of Mesh routers. After all, a set of three Mesh routers needs 1999.

Personal use example

▲ First, use USB-AC68 to connect to RT-AC86U’s 5G WiFi, and then put my NAS (wired Gigabit network cable connection) into the Z disk of the local computer to measure the network connection speed. This speed is basically the highest, because the conversion between wireless network and wired network and the need for packets for signal transmission will occupy the transmission bandwidth.

▲ The signal strength test that everyone cares about, the layout of my home, and the emmmmmmm drawing software is called Sims 4, which is made by EA who sells DLC. Common locations are marked in the above picture, and the following picture shows the perspective with walls. It can be seen that the signal has crossed several walls. The router is in the small bedroom, my room, only 1 meter away from the bed.

▲ A picture shows that the attenuation of 2.4G signal is less, but the transmission speed of 5G signal is fast, and the signal strength is very good if it is close to the router. What? You said that the 5G signal toilet is weak to use?

▲ Let’s measure the 100M broadband next to the router, and compare it with the signal measured in the toilet with the worst signal. You will find that even in the toilet with the worst signal, there is no problem in brushing Weibo, watching videos, watching TV dramas and playing games (the delay is not improved). In actual measurement, don’t be superstitious about signal strength, it is enough. After all, SRRC standards will be stricter.

The glory of the king/chicken-eating mobile game measurement

　

▲ I played three the glory of the king, two wins and one loss … When the game was operated, there was no delay caused by communication, and the operation was smooth. Even a hero like Liu Bang, who has a lot of hands, can accept five heads.

▲ Jedi survival stimulated the battlefield and also ate chicken.

summary

For the replacement method of light cats, I recommend schemes 1, 2 and 3. The fourth type is highly recommended by individuals who change the bottom layer, because the gap is around 50 yuan, which is not worth your trouble, and the life span of second-hand light cats is very poor. Once it collapses, it will be very painful.

I recommend Optical Cat to be used as a photoelectric conversion device, so as to prolong the life of Optical Cat and enable it to support the future 10 Gigabit optical fiber+10 Gigabit network. We connect a good wireless game at the back end, which can not only enjoy high-quality WiFi and intranet, but also have better expansion functions.

In the process of use, I think AC86U is very suitable for me. It saves space by being placed vertically, with excellent performance, rich functions and sufficient signal strength. After all, the SRRC standard is strict.
