Hi @zainulhasan

Unable to connect 5 GHZ

We need to take a look at the module parameters that you are using. Run the following from the driver directory and post the contents of the first options line:

$ sudp ./edit-options.sh

I need to know your country to provide a complete answer.

showing two wifi

You have activated Concurrent Mode. To deactivate:

$ sudo ./remove-driver.sh (depending on the script you used for installation)

$ sudo ./cmode-off.sh

$ sudo ./install-driver.sh

Since users can come here from many places, I like to point them to the site Main Menu as it contains a lot of good information for those of us that use USB WiFi adapters:
