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!
Assuming you used the instructions above to create a WPA/WPA2 2.4 GHz network, I'd clear out the setup on the Canon printer and return it to the way it was when you first configured it. After you've done that, could you try again to connect your gateway to the printer?
¡Buena suerte!
