Q. I have upgrade from win7 to win10 (64 bit both).
After upgrade my network adapter don’t recognize wifi 5HGz, it can see only 2.4 Ghz.
Before upgrade both bands were accessible. It is the same device.
Network adapter is 802.11n , connected with USB.
It is dual band USB adapter TP_LINK, TL-WSN3200 V1.2.
I checked if driver need to be updated in “driver detailes” section, it is o.k.
Please advice.
