So I've been using this computer to connect wirelessly to a router in another part of the house for the past few months. Then one day, I started getting this 'Windows was unable to connect to SSID' error message. I've tried the below :- Disabled and enabled the wireless adapter. No effect.Switched to a wireless adapters of another brand and model. Worked for a while and then the same error message popped up.Turned the router off and on. No effect.Formatted and reinstalled windows. Worked for a while and then the same error message came up.Tried looking for updated adapter drivers but there's only one driver on the manufacturer's website so that wasn't the cause.Tried the ipconfig /release and ipconfig /renew. No effect.Tried the netsh commands. No effect too.My system had had no hardware changes at all so what could be the problem. Please help because I sure wouldn't want to spend unnecessary money buying a new router or applying for another line. A screen capture of my ipconfig /all results is over here.
