A while back, there was a big Windows 10 update and since then, I have not been able to get wifi directly from my main router. Oddly, I can connect to wifi through my D-Link extender, which has the same name, with EXT5G appended to the name. I've deleted the networks on Windows 10 and started from scratch, rebooted the router numerous times, etc. and I still can't get it to work. Any thoughts? Thanks.
