Windows 10 not Recognize 5GHz wifi

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.

unfortunately, I was unable to find the Wireless adapter make and model. Let us know the make and model of the Wireless adapter.
