And pull out another WiFi dongle and test.
I'm currently using a Wireless network adapter for my PC, and haven't experienced any issues with it until now. I don't think it's to do with the Adapter.
(For context my wireless adapter is called "Wifi 2")
All of a sudden I get the yellow warning sign next to the WIFI symbol, I use Windows diagnostics and it says "Wifi 2" doesn't have a valid ip configuration, once I enter the IP/DNS I use Windows diagnostics again and a new error appears "DHCP is not enabled for "Wifi 2" " And it gives me the option to fix the problem, once I do this it gets rid of the IP I entered and I once again use Windows diagnostics and I'm back to square one " "Wifi 2" doesn't have a valid ip configuration" "
This is very frustrating and have possibly tried everything, from tinkering with the Admin panel for my router and giving my Tower a reserved IP for it.
