I have a TP-Link Router (Archer C1200) and 2 wifi extenders (TL-WA850RE). The extenders connected perfectly to the router using WPS, however, after an hour or so, they no longer connect to the Internet. I have tried to follow the instructions of a range of other threads, however, they don't appear in my network map. I have re-connected them several times, and the same thing occurs.
This is becoming frustrating as I am working from home and cannot access reliable Internet during the day.
Some help would be appreciated.
