Nokia 5G21 is one of the Prior Default 5G Router that T-Mobile used to Provide. It has good specifications as well as particularly good user experience with slight heating issues mentioned by some users. Although, when it comes to Advanced Features that some users expect in this type of routers will be a bit disappointed. As this router is as basic with just Some Wi-Fi Settings and that’s it. For Advanced users I Would strongly recommend getting a separate router and connecting to it.

Router Login

Entering Router settings is quite easy. As usual with all other routers connect the Wi-Fi or ethernet and enter the IP Address that is 192.168.12.1 . You will get the interface as shown below with information’s. Additionally, you can also get these settings from T-Mobile Internet Mobile App on smartphones.

Now for logging in entering the Administrator Password that’s in the label in bottom of the router with label “Admin Password” (pic attached below you can check under the router). And you will get All Router settings. And you are good to go. If you want to change your Wi-Fi Name and Password, then follow the Next Step. Otherwise, you can Exit. Have a Good Day.
