Estoy corriendo
uname -r
4.10.6-1-ARCH
en mi dell XPS 13 Developer Edition (2014). Actualmente tengo problemas extraños con mi wifi (uso Networkamanger con nm-appletKDE):
1) en el nivel más superficial, observé que a veces funciona perfectamente: cuando inicio mi PC, ya se ha conectado al wifi, y a veces no se conecta de ninguna manera (el wifi es siempre el mismo);
2) Intento reiniciar NM: y el problema persiste. 3) A veces, si reinicio mi computadora portátil, funciona de nuevo, a veces no.
4) Traté de usar nmcli
nmcli connection up My-WiFi
entonces observo
dmesg

3) Si uso un escudo etéreo con cable usb, puedo conectarme a NM sin problema;
4) Intenté también conectarme directamente wpa_supplicant, pero fue imposible debido a errores de autenticación, sin embargo , recalco que mi ID de usuario y mi contraseña son correctos, ya que a veces puedo conectarme sin ningún problema.
¿Qué tengo que hacer?

¿Ha habido modelos XPS anteriores a 2016 con grandes problemas de interferencia entre dispositivos wifi y USB debido a que las interfaces están cerca unas de otras, que se han mitigado en versiones más recientes? ¿Estás utilizando dispositivos USB cuando tienes ese problema?

Me di cuenta de que enchufar usb eth shield puede modificar el comportamiento del error wifi. Pero no parece ser determinista. Sin embargo, racionalmente pensando que debería ser posible detectar el problema.
