How to hide optical modem WiFi? If you can’t find it on ChinaNet, don’t rush to report it for repair. The switch is hidden on the SSID page.

The reason is that my wife said something: The owner of the convenience store downstairs asked her, "Is your WiFi called ChinaNet-9F3a?" I searched it on my grandson’s phone." The names and suffixes all match, it's the one of my optical modem. I mean no harm, but my wife stopped working when she came back and insisted that I "delete" this name from other people's phones. It cannot be deleted by deleting it. The name was broadcast by optical modem and can be searched in the whole building. What you can do is to turn off the broadcast so that it does not appear in the search list. This is the so-called hidden WiFi. I modified my own Huawei HS8145V5 and my mother-in-law’s ZTE F7015T. It only took half an hour, but I encountered three pitfalls in the process. This article will record the paths and pitfalls.

Think about it first: Who can be guarded against by hiding, and whom can't be guarded against?

You have to set your expectations before taking action, otherwise your work will be in vain. The name of optical modem's WiFi, which is called SSID in jargon, is usually visible to surrounding devices through the action of "broadcasting" - optical modem will shout "I am ChinaNet-9F3a, I want to connect" every once in a while. Hiding means closing the throat. If you search it on your mobile phone and computer, it is indeed not on the list.

But there are two types of things it cannot guard against. One type is a professional scanning tool. Hidden networks will still appear as "unknown networks" in the scan results because the device will still respond when it actively calls. Anyone who really wants to surf the Internet can use a tool to scan the information accurately. Hiding will only cost him two more minutes. Another category that cannot be defended is your own equipment. This pitfall is even bigger and will be discussed separately later.

So my positioning is: Hidden and guarded against are "smooth neighbors", like changing a long password, Block network-robbing devices It is a three-door combination that cannot be used alone. If you hope to hide a trick to keep yourself safe, give up the idea as soon as possible. If no one is using your optical modem’s WiFi and all the devices are connected to your own router, then don’t bother hiding it, just use it The article about Guangguangmao WiFi Turning it off is ten times cleaner than hiding it. Hiding is more suitable for the kind of home where "there are really two or three devices hanging on the optical modem WiFi, but you don't want to see the name in the whole building."

Take action: The switches of the three machines are all near the SSID page.

The path is the same as changing the WiFi name. Connect the mobile phone to the WiFi of optical modem - don't skip this step. The WiFi connected to your own router goes into the backend of the router. What is changed is the router, which has nothing to do with optical modem. Then the browser enters 192.168.2.1 , useradmin login, the password is on the sticker on the back of the optical modem. Go in and look for the words "WLAN" or "wireless":

The first time I didn’t find it on the Huawei platform, it was because the menu name was not called “Hide”. The firmware translates to "Enable SSID Broadcast", and it is hidden if it is unchecked. This check box says the opposite, so look carefully before clicking it. The menus of no-name machines such as Tianyi and Youhua are even more confusing. You can’t find anything after flipping through it twice. Overview of the backend menu First match the menu name.

Don’t panic about permissions: useradmin is enough. Wireless settings such as turning off the wireless switch and changing the name and password are all in the hands of the ordinary account. They have nothing to do with the super password. There is no need to gnaw at the hard nut of telecomadmin.

The biggest pit: Dual frequency needs to be hidden twice

This is something I practiced at home. Optical modem turns on "dual-band-in-one" by default. The 2.4G and 5G broadcasts have the same name, but there are two entries on the configuration page. I removed the 2.4G broadcast, saved it, and searched it on my phone - the name was gone, which was quite satisfying. When I took the tablet into the bedroom at night, the 5G signal was still full of that name. In other words, I only hid half of it, and the 5G section is still open.

Judgment method: After changing and saving, go back to the SSID list page and take a look to see if both the 2.4G and 5G entries have changed their status. If you had pressed Dual-band disassembly article The two frequency bands have been split into two names, and they have to be hidden one by one. Missing one means missing nothing. My mother-in-law’s family’s ZTE was good to me the second time. I clicked on two items one by one and changed them, and I got it right in one go.

At the moment of saving, the FamilyMart WiFi device went offline on the spot. It was normal for the phone page to rotate in circles, and the wireless module was restarted. Just wait for ten seconds to reconnect, don't be stupid and click save repeatedly.

After hiding: My phone can’t connect, so I have to report my name manually.

The broadcast is gone. If you don’t know the name of the new device, it won’t be found. You have to tell it manually. For Android, go to Settings → WLAN → "Add Network" at the bottom. For iPhone, go to Settings → Wireless LAN → "Others" and fill in the name and password as they are. There must be no mistake in the name, including uppercase and lowercase letters - my wife couldn't connect to her cell phone, so she looked over and changed the uppercase F in her name to lowercase. If the password does not match, the error message will keep spinning around. If the name is typed incorrectly, the search will be ignored and "Network Not Found" will be reported directly. Memorizing these two types of errors will make troubleshooting much faster. The complete paths and encryption methods of the four systems, The article about router hiding WiFi There is a cheat sheet in it, which is exactly the same for cats, so I am too lazy to copy it again.

Don’t choose the encryption method randomly. When adding a network manually, the page will ask you to choose WPA2, WPA3, or something else. Which mode is actually enabled on the optical modem? Go to the background wireless security page and take a look before filling it out.—— The article about optical modem encryption method I've been through this pitfall before. I chose the wrong one, and still couldn't connect even though I had the correct password. The error message looked exactly like the wrong password, which was very bluffing.

Most of the devices that have been connected and have saved passwords will take the initiative to find the hidden name and reconnect. It only takes a few minutes for such devices to be disconnected. For those who don't know the way, just delete the saved network and add it manually again. Can't tell which type it is, see the error message: You don't need to do anything since you will come back. If you can't find it even after waiting for ten minutes, you need to take action.

The sweeping robot is the most injured

Mobile phones and computers are easy to handle, but what really bothers people is smart devices. Apps like Mijia configure the network by scanning the WiFi list. There are no hidden names in the list, and the network configuration process cannot proceed directly - the app asks you to "select the 2.4G network" and the page is empty. Sweepers, cameras, and smart speakers all have the same function. My solution at the time was not to hide 2.4G, but to feed smart devices specifically, and to hide the daily frequency band of 5G. The idea and pitfalls were Smart device distribution network troubleshooting article It’s all written down.

There is another judgment question to do first: If your home's optical modem WiFi has only one signal and all devices are connected to the router, no one will care whether the optical modem is hidden or not. It is cleanest to just turn it off as mentioned at the beginning. If there is really equipment that needs to be hung on the optical modem—for example, if the router breaks down in case of emergency, or in a small apartment that is too lazy to install a router—clearly calculate the hidden costs before taking action. The article about weak WiFi signal of optical modem You can look at the stop loss line. If it is weak below that line, you should change your approach whether you want to hide it or not.

Will the operator change it back in the middle of the night?

I was muttering about this before the change. After all, the optical modem is the operator's equipment, and ITMS pushed the configuration in the middle of the night. ITMS article Wrote in. The good news is that wireless settings such as WiFi names, passwords, and broadcast switches are "user reserved areas." Computer rooms in most provinces do not touch them. What will be pushed back are changes related to business activation such as bridge mode and VLAN. I took a special look at it the next morning after making the changes, and it was still hidden. It had not been touched for more than a month.

Mobile users should be more careful. Their RMS should be pushed more frequently. If it is really changed, just change it again. It only takes two minutes. China Unicom's regulations are more fragmented in each province, and different batches of firmware in the same province can differ greatly. Don’t get angry if you really encounter it. This does not lose the configuration. Just change it again and come back. Take a screenshot on your phone and save it, so you can have evidence next time.

There is also a hidden connection, a reminder: Change password, The article about changing WiFi password on mobile As mentioned in the App path, these operations and hidden switches are neighbors on the same page. When you change the password on the App, some firmware will rewrite the entire page of wireless parameters, and the broadcast check may be unchecked for you. After changing the password on the App, it only takes less than half a minute to go back to the background of the web page to check the broadcast status.

Make a final list: Mobile phone connected to optical modem WiFi→ 192.168.2.1 Go to the background → Find the broadcast switch on the WLAN configuration page → Change each of 2.4G and 5G → Save and wait for ten seconds → Manually add the name of the new device. After making the changes, I went downstairs and met the convenience store proprietress. She said, "Why can't I find your WiFi?" You knew that half an hour was well spent.

One more fair word: In terms of priority for preventing network fraud, long passwords are ranked first, disabling WPS is ranked second, and hiding at most is ranked third. The article about limiting the number of devices in optical modem The solution ranks fourth. Having done the first three things, hiding is the icing on the cake. ； If you don’t do the first three things, just hiding a name is like painting the door on the wall.
