Having problems with WIFI - I think

I’ll try to explain my issue in as few words as possible

I have T-Mobile wifi

recently my printer and indoor camera stopped connecting to the router

tried resetting, unplugging, bought an identical camera and still can not connect

Everything else worlds like the tv, computer, phone etc

do I troubleshoot with a
T-Mobile or my printer and camera companies

 

If you rebooted everything, including the T-Mobile device, and other things are working, then I'd go to the camera and printer support folks.

 

Have you had any power outages recently? I've had to reconfigure smart switches sometimes after outages. You may want to verify the configurations.

 

When was the last time you updated your drivers? You try doing a re-install on the printer and camera?

 

I know this is an old post, but it could be that your printers and cameras do not support the wifi channel that the T-Mobile wireless router is running. If this is the case then you would need to configure the T-Mobile wireless router to only operate on wifi channels supported by your least capable device.

 

Do you still need help?
