[SOLVED] WiFi connection speed issues with TP-Link TL-WN722N [SOLVED]

Post by lazzar » Sat Feb 24, 2018 8:14 pm

Hi all,

I'm having issues with my WiFi USB adapter (Linux Mint 18.3, Cinnamon 64bit, Kernel 4.10.10-38-generic) After some time connection speed drops to zero (it stays connected though).
In order to continue browsing I have to unplug the USB adapter and then plug it back again.

Thanks in advance!

I have been using the TP-Link TL-WN722N v1.0 with the Atheros AR9271 chip with all LM kernel versions without any problems/drops. All I did was disable power management (power savings) for wifi.
TL-WN722N v2.0 and 2.1 use the Realtek chip, so your mileage may vary.
