How to change the name of Telecom optical modem WiFi? I couldn’t tell who was who on ChinaNet. I changed the name in three steps and ten minutes, and I flipped through the menus of all three cats.

Last year, my aunt installed broadband in her home. After the master adjusted the light, the cat left. When she took her mobile phone to connect to WiFi, she asked me something.: What is this string "ChinaNet-a4f3"? I said this is the default name of the WiFi that comes with optical modem, starting with ChinaNet, and the following part is the optical modem number, one for each machine. The three households upstairs and downstairs in her house had the same monthly broadband, and all three ChinaNets were listed in the WiFi list. She missed it twice in a row - she connected to the one upstairs. The password was actually correct (these were all default weak passwords used by the installer to save trouble). The Internet speed was so slow that she was scrolling through videos, and she thought her own broadband was not good.

I remember this to this day. The name optical modem WiFi has never been used by most people since the day it was installed, and it has been around for several years. When you really want to change it, go ahead 192.168.2.1 I couldn't find the entrance after searching for a long time in the background, only one of the dual-bands was changed and the other was missing, and all the smart devices at home lost contact after the changes. This happened to me four times. This article clearly describes the name change path of the three telecom optical modems, the naming rules, and the ending of the change.

First distinguish: Is the name you want to change in the optical modem or in the router?

Before taking action, first check the mobile WiFi list to see what the name of your home connection begins with. The one at the beginning of ChinaNet- is the WiFi sent by optical modem itself. Modify it and enter the optical modem backend. The name is your own (for example, "living room WiFi" or "our home"). It is issued by the router. You have to change it in the backend of the router. The two entrances are completely different. Don't visit each other. This judgment method can be explained in one sentence, but someone actually took the router tutorial and read it in the backend of optical modem all afternoon.

There is also a type of family that has both.: The optical modem is ChinaNet, and the router has its own name. In this case, I suggest turning off the optical modem WiFi directly, leaving only the router one, so as to avoid connecting the mobile phone to the wrong network. I am in the process of closing How to turn off WiFi on Telecom optical modem It was written in that article. If you want to keep optical modem WiFi as a backup, then this article is for you to change your name.

Go backstage: The mobile phone is connected to the WiFi of optical modem (the one to be renamed, do not connect it to the router), and the browser enters 192.168.2.1 , the account number is on the sticker useradmin , the password is the string of one machine and one code on the sticker. The entire name change process does not require the super password telecomadmin, a normal account is enough - the WiFi name belongs to the "user private area" setting, and the operator delegates authority by default. Which line on the sticker is the password that you can’t see clearly? Please read what I wrote. The optical modem sticker article . If you can’t log in, click first. Mobile login 192.168.2.1 That article After arranging the order, most of them are stuck in the wrong WiFi connection and wrong capitalization.

The renamed entrances of the three machines have different paths.

The step of changing the name itself has no technical content. The difficult part is the menu. Customized firmware is not unified across telecom provinces. With the same word "Huawei", the menus of the two provinces can be one level different. I have touched three of them, and the path is copied below.:

The common rule is to recognize the word "WLAN" or "wireless" and go in and look for the input box marked with the SSID name. There is usually a wireless switch and password box next to the page, so don't slide the switch to click. The menus of no-name machines such as Tianyi and Youhua are even more confusing. If you can't find it after searching twice, go first. 192.168.2.1 Overview of the backend menu Matching up the menu names and then doing it will make it faster than doing it blindly.

This is the biggest pit: Many optical modems have "dual-band-in-one" turned on by default. 2.4G and 5G broadcast the same name. You change and save in one SSID box and think it's done. In fact, the entry for another frequency band still has the old name or old configuration, and the phone is still connected to the old name. My cousin was in trouble this time. The old tablet in his bedroom could not be searched online the night he changed his name. Judgment method: After changing and saving, go to the SSID list page and take a look to see if the names of the 2.4G and 5G entries have changed. If you originally wanted to split the two frequency bands into two names, that is another matter. The process is The article about setting up Tianyi gateway 2.4G and 5G separately , after taking it apart, they changed their names in one step.

How to get the name: The three rules are what I paid for in exchange for tuition.

The name change box is right in front of you. You have to be careful about what you fill in. I stepped on the three items.:

• Don't use Chinese . The wireless module of old printers and laptops could not find the Chinese name SSID. My aunt's old Internet radio was so blind that after a night of troubleshooting, I found out that the problem was with the name.
• Alphanumeric short name , within 20 characters. Some old devices with names that are too long may not be fully displayed, which may lead to glitches during pairing.
• Do not use house number, name pinyin, or mobile phone number . The WiFi name is broadcast and can be searched throughout the building. A name like "Wang Jianguo of 802" is equivalent to hanging your home information on the door.

Another reminder: It is recommended to add a 5G suffix to the name of the 5G frequency band, such as jia302 and jia302_5G , you can understand at a glance which frequency band the mobile phone is connected to, and you can save half the trouble in troubleshooting "why is it slow as soon as you enter the bedroom" in the future. If you want to change the password at the same time, the process is the same, just fill in one more box. The WPA key box is the password. I wrote the details in How to change the WiFi password of Telecom optical modem In that article, it is easiest to change the name and password on one page.

What happens when you click save?

Save and press it, the Optical Modem wireless module will restart, and all devices connected to this WiFi will be disconnected on the spot, including the mobile phone in your hand that is operating in the background. It is normal for the page to get stuck in circles, and the parameters have actually been written in. The first time I changed it, I was scared. I thought I had changed the cat, so I had to cut off the power and restart it for a long time. The correct approach is to wait for more than ten seconds, reconnect the phone, enter the password corresponding to the new name (if the password has not been changed, enter the old password), and then enter the background to confirm.

A more stable method is to take a network cable, plug it into the computer's LAN port and make changes, keep the network connected throughout the process, and then reconnect to the phone after making the changes. It doesn’t matter if you only have your mobile phone at hand, but don’t panic if you are disconnected for more than ten seconds.

Not all devices will come back on their own after being disconnected. The mobile phone and computer will automatically reconnect. The trouble is that those smart devices only have the old names saved.:

• Sweepers, cameras, smart sockets: If the name changes and they cannot find the network, they need to re-configure the network, delete it in the App and try again.
• TV box: Go into the network settings to select a new name and enter the password.
• Guest mobile phone: Next time you come as a guest, you will be asked for your password again. This is the social cost that comes with changing your name.

Therefore, the timing of changing the name is very important.: Don’t do it at 9pm when the whole family is online. Pick a time during the day when no one is around and finish it in ten minutes. On the night after the modification is completed, pay attention to whether there are any device offline alarms in the App, and if so, reconfigure them one by one. If you have a lot of smart devices at home, count them before changing them. If you have more than ten smart devices, make a half-hour budget. Don’t expect full automation.

Will it be changed back in the middle of the night?: There’s basically no need to panic about the name.

Before I changed my name, many people asked me the same question.: Will the change be pushed back by the operator in the middle of the night? I am here ITMS push configuration article After sorting out the rules, the changes that will be covered in the middle of the night are bridge mode, VLAN and other changes related to opening services. WiFi names and passwords are reserved for users, and most provinces do not touch them. If you are worried, just take a look at the WiFi list on your phone the next morning. The name is still the one you named, and you will be at ease. Don’t panic if it is changed back. If it is changed again, just take a screenshot to keep proof.

There is an exception to be made: If your optical modem has been changed to bridge connection or router dial-up, then the optical modem's WiFi may have been turned off, or the name has been changed and the device is no longer connected to it. This kind of name change is of a tidying nature. Don't expect it to bring about any changes in network speed. Just clean it up easily. How to enter the backend of optical modem after bridging, see After changing the bridge 192.168.2.1 Can't get into that one , a static IP thing.

wrap up: Ten minute process checklist

Collate the entire process into a checklist and follow it through:

It’s been more than a year since my aunt’s house was renovated, and the WiFi is called yijia5f , I never missed it again upstairs or downstairs. Her own summary is better than what I wrote.: 「This name is like a house number, you have to nail it on yourself. 」The difficulty with the name of the optical modem is zero, except that no one tells you where the entrance is - now you know.
