Created attachment 206001 [details] ifconfig wlan0 Hello, i use an "Netis AC1200 Wireless Dual Band Adapter" with an RTL8812au chip. My problem is that my download & upload speed gets stuck at 2.4 MB/s. In the beginning, i had even every 5th minute a very large lag and got solved by set the Frequenz to 2,4 GHz only.
