Canon printer won't connect to TMobile wifi router
I was using AT&T but changed internet service over to TMobile. Now neither my Canon all in one nor the HP simple printer will connect. ¡Ayuda!
Your problem is pretty common among T-Mobile Internet users. This usually fixes the problem.
Try adding a new WiFi network for the Canon(s). Use the T-Mobile app and tap the Network tab on the bottom, then the "+" button on the lower right. Create a new 2.4 GHz WiFi network with a unique name (SSID), just for your printer. Make sure the WPA type is WPA/WPA2. This is different from your main network which, by default, is WPA2/WPA3.
Now, go to your printer and clear out all of the information you have entered for your printer's setup and then recreate your wireless connection to the new network you just created. I'll bet you'll be good to go.
¡Buena suerte!
I don't have the skills to make and mark up screen shots from my phone. However, these written instructions did help someone else:
T Life app instructions to create new 2.4 GHz network:
Connect (at the bottom) > Things (at the top) > tap your Gateway > tap Manage > under My Networks, you will see each one you already have.
To create a new network, tap Network (at the top.) Under My Networks, tap + Add Network to open the page to set up your new network. Give it name (SSID) and a password; select the frequency band (2.4 GHz); select the WPA version (WPA/WPA2). (Encryption mode is automatically set when you select a WPA version). Tap Save at the bottom.
