Bought an Archer T4U v3 recently and constantly experiencing disconnects on 5GHz wifi on Windows 10.
Every 30 mins or shorter, the dongle will disconnect from wifi and I can hear a sound in Windows like the USB device has been removed and reinserted.
My channel width is 80 MHz and I have tried channel 36 and 161. Experienced the same problem when my Asus AC68U router set to Auto so I decided to set fixed channels.
I am using the latest TP-link drivers from the Southeast Asia website. Also, every time I hear the sound like the driver is removed and reinserted, the driver switches back to the default driver in Windows ("TP-Link Wireless Adapter", date somewhen in Oct 2018).
I bought this adapter so it can work with 5GHz wi-fi in my room which my laptop and phone is working fine with.
Windows Wlan report shows the constant disconnects:
I have tried changing USB ports and computers too but the solution persists.
Any reason what is causing this problem? Thank you.
