Windows 10 Lost my 5GHz Wifi

Post by BobH »

For reasons unknown to me Windows 10 has lost the 802.11n driver. I've searched but every avenue has met a roadblock. When I go to my Network Connections I do not find any reference to the 5GHz network that is set up. I can find no driver for this band.

Can anyone point me to a wiki known to work? I've chased so many bad leads that my frustration level has risen leading me to make more mistakes. I don't want to do any further harm; so I come here for help and wisdom.

EDITED:
Providing more information, my router (Linksys EA7300) shows both networks but when I show available networks in Settings > Wifi the 5GHz network does not appear. This leads me to believe that the problem is with my laptop because iPhones and iPads are linked to the 5GHz network. There is no 802.11n driver in Device Manager > Network Adapters > Properties > Advanced shows no 802.11n property.

When I search for an 802.11n driver for windows 10 I get a plethora of options. Making it worse, most hits lead to downloading driver management software, none of which I trust due to past experience.

Are you sure that this device is capabile of connecting to a 5GHz network?
According to this page at cnet it is 2.4GHz only https://www.cnet.com/products/atheros-9 ... i-adapter/

Hi Stuart!

Thanks for the response. I ran the following. It shows that the card can handle 802.11n. Isn't that the 5GHz band?

Also, CNET shows it to handle the same.

802.11n is a protocol that can use either 2.4GHz or 5GHz
This particular card supports 2.4GHz only
