[Risolto] La connessione wifi cade

Messaggio da paozaf » 22 aprile 2013, 11:57

Ciao a tutti.
Ho un asus nv56 con una scheda wirelless Intel Corporation Centrino Wireless-N 2230 (rev c4), la versione del kenel è la 3.8.7-1.
Ho un problema con la connessione wifi (uso network manager): si connette, navigo, ma connessione cade ogni 2 secondi (anche se poi ritorna attiva).
Un dmesg dice:

Credo che il problema sia collegato a:

Ma devo installare ipw2100-fw e/o ipw2200-fw?

Nella guida ufficiale c'era il modo per capirlo con tanto di elenchi e periferiche supportate. Non te lo dico direttamente perché onestamente non me lo ricordo.

Non so davvero come risolvere.
Provando con un'altra rete wpa non riesco proprio a connettermi, anche se il kernel non da qui messaggi.
Con altre reti invece non ho problemi, anche wpa, mi collego tranquillamente.
Qualcuno ha qualche idea?
Ditemi se devo fornirvi qualche altra informazione (log, impostazioni, ecc), non ci sono problemi.
Capite che purtroppo è una cosa abbastanza importante e senza connessione wifi funzionante mi vedo costretto a installare qualche altra distro (cosa che non voglio assolutamente...ma se non ho altra scelta)
Grazie mille

Ho novità.
Uno sviluppatore del kernel mi ha detto che il problema non è dovuto ad un bug del sistema ma a una qualche cosa di strano tipo una doppia istanza di wpa_supplicant.
Quello che lo porta a pensare questo è una riga dell'output di dmesg, in particolare:
[ 1756.822019] wlp3s0: deauthenticating from 74:ea:3a:cd:28:42 by local choice (reason=3)

Qualcuno sa come posso capire da dove arriva il problema?
Grazie mille

LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.

79 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.
da notare i due failed nella riga:

In questo post https://bbs.archlinux.org/viewtopic.php?id=146052 qualcuno dice che ha questo problema e che è dovuto proprio a qualche demone doppione, in particolare per "network" (che deve essere disabilitato) e per "networkmanager" (che deve rimanere).
Voi cose ne pensate?

Penso che siano o le schede intel o quel modulo. La mia cade sempre o si disattiva del tutto. Ormai ci ho rinunciato :P

beh in effetti ai tempi precedenti a systemd c'era il discorso di disabilitare il demone "network" quando si usavano altri strumenti per la connessione (aka networkmanager o netcfg)

hai provato a usare altri metodi di connessione tipo wicd?

ieri sono riuscito finalmente a risolvere il problema delle disconnessioni con il chipset intel ipw2100..
ho dovuto disabilitare il 'frame burst' nelle impostazioni wireless-avanzate del router.. ma più una disconnessione.

vedi se funziona anche con questa scheda intel

Tutto risolto, avevo più di un servizio che cercava di gestire il dispositivo wifi.
Ho risolto tutti i miei problemi con:

Codice: Seleziona tutto

systemctl disable NetworkManager-wait-online.service
systemctl disable net-auto-wired.service
systemctl disable net-auto-wireless.service
Grazie mille
