XPS 13 9300 Developer Edition with very weak Wifi signal on linux
I am experiencing a very weak wifi signal with my XPS 13 9300 compared to other devices. The connection is so weak that it very frequently disconnects and then reconnects (sometimes multiple times within a minute). This renders the WIFI connection extremely unreliable.
Here's the output of "iwconfig" with the laptop just one room away from the router
lo no wireless extensions.
wlp0s20f3 IEEE 802.11 ESSID:"<redacted>"

Another laptop shows a link quality of 57/70, signal level -53dBm with a Tx-Power of 15 dBm in the exact same location. My android phone also shows a signal level of ~-50dBm.
