Windows – Connection to 5ghz network has no internet for supporting wireless card

driverswindows 10

I just got a new wireless card for my Windows 10 desktop, the fenvi fv8801. By other user accounts and product description it supports 5ghz networks. My wireless router is the Linksys EA7400, again, 5ghz compatible. When I try to connect, I am able to get to the 2.4ghz network, but not the 5ghz network- it connects but says internet is not available. I suspect it's a driver or configuration issue as I can get the 5ghz from my phone and everything works.

I also have made sure the computer has all the drivers it needs. It appears the wireless card works on the Intel chipset and uses the standard Intel wireless drivers, so nothing spooky there.

I suspect that I am seeing some sort of strange holdover from the old wireless card- like it needs deleted or the drivers are still around or something. I noticed that in my Network Connections it's listed as Wi-Fi 2, but I can't rename it as just Wi-Fi because that one "already exists" however, I don't see anything with such a name as that in my list.

Anyone have any thoughts on troubleshooting this? Is my card just a lemon or something or is my configuration bogus?

I am not 100% sure what the issue was, but I think it had something to do with the broadcasted channel that was being used by the router. In the wireless router settings, I changed the channel from "auto" to the highest one supported by my router "161 - 5.805 Ghz". I am guessing that it was either doing something stupid, or my card doesn't support certain lower channels.

Either way, setting it explicitly to that worked.
