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 finally got my Canon IP8720 connected by using the USB to Wireless option.
First connect usb cable from printer to computer, follow instructions. At one point it tells you to disconnect the USB and then it finishes up the wireless side.
The printer now works on the 2.4 and 5ghz networks.
