How to change the WiFi password of Mobile optical modem? I forgot my password for the hotspot at the beginning of CMCC. There are two ways to go backstage and mobile Aijia.

My cousin's house upgraded to a Gigabit mobile phone last month. After the master installed it, he left behind a Huawei HS8546V5, with the wireless name being CMCC-7Gd2. At that time, he was too lazy to change it. Now he wanted to change the WiFi password at home at work, but he couldn't remember the backend account, so he almost went to reset it. Don't panic, changing the WiFi password on Mobile Light Mode really won't go that far. In both cases, listen to me and identify the target clearly.

First, make it clear that what you want to change is the cat at the beginning of CMCC

Correcting the wrong box is the most common wasted effort. He has a router he bought at home, as well as a CMCC hotspot that comes with the optical modem. When he scans it with his mobile phone, the signals of both are quite strong. Which one is moving? Don’t guess based on signal strength, just look at the name.: The ones that start with CMCC, or the words "Mobile Smart Home" or "China Mobile" are optical modem ； The name you chose yourself was probably sent by the router. After changing the password of the router, the CMCC one still kept the door open with the old password.

If you are really not sure, check the gateway in the WiFi details of your mobile phone. For Android, click on the arrow to the right of the current WiFi, for Apple, click on the blue "i", and the gateway column says 192.168.1.1 is the mobile optical modem ； written 192.168.31.1 Something like that, a router. If you don't get this step right, all the rest will be in vain. After changing the password, I found that my old phone could still connect , nine out of ten people make trouble like this.

Mobile homes often have three sets of passwords, so don’t mix them together yet.:

Web backend: If the user account can be changed, don’t touch the super management

90% of the default address of Mobile optical modem is 192.168.1.1 , there are also stickers for Huawei models 192.168.100.1 , type http:// in the address bar, do not type in the search box. In the login box, fill in user as the account number, and the password as shown on the sticker on the cat’s butt, one for each machine, not a unified admin. My cousin’s station is a typical one: The sticker says "Default terminal configuration account user", and the string of letters and numbers below is the key to the door.

Go in and look for "Network" or "WLAN". Most of the places to change WiFi are in the wireless settings. Look for the SSID name and WPA pre-shared key columns. The former is the WiFi name and the latter is the password. The password field is covered by dots by default. If you uncheck the "Hide" checkbox in front of it, you can see the clear text set by the master at that time. I have seen many passwords for mobile devices that are just the last letter of the phone number. When I saw it, I decided to change it.

There is a mobile modem with old firmware. The user can check and change it after entering it. Just check out at this step. Don’t bother with CMCC Admin. Unless the wireless menu is completely grayed out and only shows no clicks, then super-management is needed. The mobile super management article Leave the CMCCAdmin path in until then.

What’s the difference between the menus of Huawei and ZTE mobile phones?

The assistant and my cousin have both tried it, and the menus at the two tables are completely different. Don't memorize the location, just recognize the words WLAN, wireless settings, and SSID.:

Different models, different provinces and different firmwares may cause differences in menu names. One principle: First press the sticker address to enter. After logging in, don’t rush to click. Scan the left menu from top to bottom until you see the word WLAN and then enter. It is more reliable than the dead path of online screenshots. When changing WiFi, only change the name, password, and encryption method. Do not touch other WAN connections.

The backend is grayed out, change to Mobile Aijia App

The web page doesn't work, so the second way is more suitable for most people. Search for "Mobile Love Home" in the app store, don't search for "Hejiaqin" before it was renamed. I have calculated the cost of changing the name earlier. . After installing it, log in with the mobile phone number you used to get the broadband, and the QR code on the front or body of the optical modem can usually be scanned out. After binding, go to the device details and find "WiFi Settings". The names and passwords of 2.4G and 5G can be changed on the phone. After saving, the cloud will send it to the optical modem.

The biggest advantage of this path is that it doesn’t require authority, and people can do it outside. The user account is locked as a read-only device, and the App is instructed to move through its own channel, bypassing the restrictions on the web page. My cousin changed his password at work that time. The camera at home was disconnected for a while, and people could see it clearly on their mobile phones. The temper of Sanjiaguangmao App I have commented that the threshold of Mobile Love Home mainly lies in binding: The mobile phone number must be the owner of a broadband household, and it is best to connect to the CMCC WiFi for the first time binding.

Don’t call it a day after making changes: Dual band, reconnect, take another look the next day

Most of the dual-band mobile optical modems have two independent password boxes. For 2.4G and 5G, only one side is changed, and the other side is still broadcasting the old password. Before saving, make sure that both frequency bands are active. The SSID can be the same or separate. The password is recommended to be the same, so it is easy for the elderly at home to remember.

Changing the password is equivalent to changing the key for the whole family device. It's okay to re-enter the password on your mobile phone and computer. Cameras, sweepers, and smart speakers that only recognize the old password have to re-configure the network one by one. If you are in a hurry, you can do it at night. There was another thing that my cousin didn't take seriously, but the password was pushed back the next morning.: Mobile RMS will regularly deliver configurations to the optical modem. If local changes are inconsistent with the central office archive, they may be overwritten. If it really happens, I'll change it again first to make the configuration stable. The principle of push back in the middle of the night between ITMS and RMS That article explained the switch clearly.

Also think about whether to keep this CMCC hotspot. If you have a main router at home, it is enough to open a guest line for Cat WiFi ； If you think it is grabbing the channel, go directly to WLAN and turn off the wireless switches of both frequency bands to make it cleaner. The article about Guangguangmao WiFi The same idea applies to mobile phones, just look for the wireless switch.

Take your seat and copy your homework

Don't jump into the super tube as soon as you get up, first look at which step you are stuck on:

Just one sentence in order: First recognize the cat CMCC, flip through the sticker to get the user account, and change the two channels if the webpage can be changed. ； The menu is grayed out and I love my mobile home. ； Let the phone reconnect the night after the change, and come back the next day to see if it has been pushed back. My cousin later left the CMCC in the SSID untouched, and only changed the password to a string he remembered. The Huawei cat has never been messed with again until now.
