hi, 

I have a TL-WA855RE repeater that is already set up and my phone and laptop can connect to the repeater without issues, I also have a desktop PC with a wireless usb TL-WN725N but it can't connect to the repeater, the phone, laptop and desktop pc are fairly in the same place but only the desktop pc can't connect to the repeater using the wireless usb

 i get a fairly strong wifi signal in windows but after entering the password it just says cannot connect to the network 

would like to inquire how to fix the connection issue with the repeater and the wireless usb?
