WiFi suddenly gets slow / after reconnect its fast again

It doesn’t work. I create these both files and did a reboot but the problem persists.

Regarding the tips from this thread: WiFi-card not recognized (Intel Wireless-AC 9260) - #2 by Cenwen I can’t install the iwlwifi-next package, i get an error during build process.

Man, this is very annoying. I cant use my PC with this wifi bug :confused:
