There are numerous reasons for unable to change Wifi password errors, and solely relying on network technicians can take a long time to resolve. Instead of that, why not fix the unable to change Wifi password errors yourself with the following guidance from Mytour.
As you're aware, changing a WiFi password is straightforward, but sometimes the process of accessing the WiFi password change section doesn't go as planned, causing a lot of inconvenience. We won't delve into the causes but simply guide you on identifying the situation and fixing the unable to change Wifi password error quickly.
Guide to fixing Wifi password change errors
1. Incorrect Modem WiFi login address
Incorrect login addresses are not uncommon because besides the traditional Modem login addresses like 192.168.1.1 or 192.168.0.1, in some TpLink Modems like Tplinklogin.net, there are other addresses that users may not be aware of. Or it could be that your Default Gateway has changed, not matching the addresses above, which can result in Wifi password change errors.
Although not 100% certain, try the following method to check your Default Gateway.
Step 1: The first task is to press the Windows + R key combination to open the RUN dialog, then type CMD in it, and press OK to access the Command Prompt.
Step 2: Once the Command Prompt interface appears, type the command ipconfig to check the Default Gateway - the current default gateway to the WiFi you're connecting to.
Step 3: Then, locate the line Default Gateway, which is the address you need to access.
2. Modem as a branch network
If the WiFi Modem you're using is a branch network, it's highly likely to encounter Wifi password change errors. Typically, the setup of Modems nowadays is to automatically assign IP addresses, meaning you'll have to disable DHCP when connecting a WiFi Modem to the main network. At this point, the branch Modem will depend on the main Modem and include default gateway ports.
So how do you troubleshoot Wifi password change errors when your Modem is in a branch network? It's not difficult at all because you simply need to temporarily separate it as a standalone Modem, meaning disconnect from the main Modem of the current network, then connect the network cable to your computer or connect to WiFi with a laptop under conditions where there's no internet connection, only LAN. At this point, the Wifi password change error will be completely resolved, and you can change the password, then reconnect.
3. Incorrect login credentials
The usual login credentials are admin / admin or user / root , but those are not always the case and can still be changed by family members, network owners, or network setup technicians. To prevent unauthorized access to unnecessary sections, some network providers (based on regions) may require setting passwords according to the network contract name, so it's highly likely your password has been changed.
Aside from resetting the modem, you can also directly contact customer service for guidance on resolving this Wifi password change issue.
4. Incorrect password format
There are a total of 3 protocols to protect WiFi passwords that you need to know, namely WEP, WPA, and WPA 2 when setting up a WiFi password. Here, WEP - Wired Equivalent Privacy is the weakest type, but if you overlook and use it, it means your security is not guaranteed. However, that's not the main reason because in this WEP format, you're not allowed to set passwords with certain special characters, so if you choose this protocol and set a password containing special characters, you won't be able to change the password.
Instead, you can choose WPA - Wifi Protected Access and WPA2, especially WPA2 with the highest security level encryption, fully encrypted to comfortably set your password with various characters and also to fix Wifi password change errors.
Above is an article summarizing the common issues of unable to change Wifi passwords with popular Modem models nowadays. Hopefully, through this article, readers can solve the problem on their own. Whether you're unable to change VNPT, FPT, or any other network provider's WiFi password.
