My Wifi Won’t Stay Connected

My roommate and I have had AT&T Wifi for over a year now and since the very beginning we have had the same problem- Our wifi continuously disconnects on all devices. It cuts in and out multiple times in an hour period. Whether it’s searching the internet on a cell phone, attempting to watch tv on a streaming service, or using a laptop or tablet device, the wifi is constantly disconnecting, giving us messages like “Action needed for wifi network,” “Wifi Network Not Available- Would you like to use Cellular Data instead,” and “There seems to be a problem with your network connection. Please try again at a later time.”

I know that it is not a resetting problem (we have reset the wifi many times trying to resolve the issue) and it’s not a weak signal because after disconnecting, it immediately reconnects with a strong signal. However, whatever you are attempting to do in that moment, immediately closes and has to be restarted. I will not buy a signal boosting device as we live in a relatively small unit.

It is EXTREMELY frustrating and after over a year of having the same issue, we are considering changing services. Need this problem fixed ASAP!
