sto correndo
uname -r
4.10.6-1-ARCH
sulla mia dell XPS 13 Developer Edition (2014). Attualmente sto riscontrando strani problemi con il mio wifi (uso Networkamanger con nm-applet
per KDE):
1) al livello più superficiale ho osservato che a volte funziona perfettamente: quando avvio il mio pc, si è già connesso al wifi, e talvolta non si connette in alcun modo (il wifi è sempre lo stesso);
2) Provo a riavviare NM: e il problema persiste. 3) A volte, se riavvio il mio laptop funziona di nuovo, a volte no.
4) Ho provato a usare nmcli
nmcli connection up My-WiFi
poi osservo
dmesg

c'è sempre lo stesso errore. Non so come risolvere. Si noti quanto segue:
1) Il mio pc è Linux freddamente (è stato venduto con Ubuntu), in particolare

3) Se utilizzo un shield ethernet cablato USB posso collegarmi con NM senza problemi;
4) Ho provato anche a connettermi direttamente wpa_supplicant
, ma era impossibile, a causa di errori di autenticazione, tuttavia sottolineo che il mio userid e pwd sono corretti poiché a volte sono in grado di connettersi senza alcun problema
Cosa dovrei fare?
