Ubuntu vede la rete ma non si connette

[matepaco]

Buongiorno a tutti.
Purtroppo la mia scheda madre ha cominciato a non funzionare più così l'ho cambiata. Un modello molto simile, tra l'altro, per non perdere l'installazione di windows (in dual boot). Su windows tutto ok, wireless compreso.
Ubuntu ho deciso invece di formattarlo e reinstallarlo. Ha qualche problemino tra cui quello col wireless: vede la rete ma non si connette

$ dmesg
....
[   84.667720] wlp3s7: authenticate with f4:f2:6d:c6:f0:67

[   92.411266] IPv6: ADDRCONF(NETDEV_UP): wlp3s7: link is not ready

questo è l'output di dmesg... Già con la vecchia mobo avevo avuto i primi problemi. Li bastava disabilitare il wifi e riabilitarlo e di solito ad un certo punto si connetteva. Ma pensavo fosse un altro dei difetti della mobo e non ci davo peso.

da cui si vede che ho una scheda che va con ath9k

Codice: Seleziona tutto

$ dmesg | grep ath9k
[    4.779140] ath9k 0000:03:07.0 wlp3s7: renamed from wlan0

ho già provato ad aggiungere

options iwlwifi 11n_disable=1 wd_disable=1

ad /etc/modprobe.d/iwlwifi.conf come visto su alcuni post ma niente...
Qualche idea?

sudo ifconfig wlp3s7 up

[matepaco]

ok. fatto ma non cambia nulla... Il comando non da output di errore ma non si connette ancora

[Vir1966]

Per capire meglio ....vede la rete ma non si connette dopo aver messo la chiave WEP?

[matepaco]

Si esatto. Dal gestore vedo in elenco molte reti tra cui la mia. Se ci clicco sopra comincia a provare a connettersi (la prima volta mi ha chiesto la password, WPA2) ma dopo un po' si arrende. Da dmesg vedo il solito messaggio

Era successo anche a me su un portatile con Xubuntu 16.04....poi ho cliccato sull'icona di rete , impostazioni e impostazioni della rete wifi a cui dovevo connettermi e ho salvato la password nell'apposito campo.....e il pc si è connesso.
Magari lo hai gia fatto, in caso prova...non si sa mai

[matepaco]

@magozurlinux: fatto tutto. Riavviato il pc (è un fisso) e niente. Non si connette come al solito

@Vir1966: Avevo già controllato. Lo spazio per la Password è già riempito corretamente

[magozurlinux]

Hai l'IPv6 attivo.

Clicca in alto a dx sull'icona di NM, vai in basso su Modifica connessioni...; clicca su Senza fili, seleziona la tua rete wireless, clicca su Modifica, vai su Impostazioni IPv6, mettilo su Ignora e clicca in basso a dx su Salva.

Disconnettiti e poi ti riconnetti; prova la connessione.

[matepaco]

@magozurlinux: fatto pure questo. Non si connette però forse è diventato un po' più veloce a darmi il segnale di mancata connessione... magra consolazione...
