If cannot find 5GHz wifi access for window 10 or any other operating system
Pleas check tip from GotMe? Whirlpool Forums Addict:
Go to Device Manger and under the Network adapters ----> TP-LINK WIRELESS USB Adapter -----> double click on it and go on the "Advanced" tab and choose the correct Country Region (5GHz).
For more detailed list of on what # you should choose you can go to https://en.wikipedia.org/wiki/List_of_WLAN_channels
Additional help:
To check which channel, check the wifi modem or router channel.
Go to 192.168.1.1 (normal access method for most router).
Go to wireless setting for 5Ghz, check the channel setting.
