10.04 - Problemi di connessione wifi con router sitecom150N X1

da **GatoLopez70** » mercoledì 14 marzo 2012, 16:36

Ciao a tutti.
Come da titolo riscontro grossi problemi nella gestione della connessione wifi tra ubuntu 10.04 e il router Sitecom150N.
Sullo stesso PC ho istallato 11.10 e non riscontro problemi di nessun tipo.

Nello specifico:
1) In avvio spesso e volentieri (a volte sì, molto più spesso no) la connessione non viene effettuata in automatico

2) Staccando e riattaccando network-manager con:

Codice: Seleziona tutto: sudo stop network-manager

Codice: Seleziona tutto: sudo start network-manager

riesco a collegarmi in wifi.
Ma la connessione risulta problematica. Stacca spesso e rimane lenta.

3) network-manager-applet gestisce stranamente la connessione:

Adesso, ad esempio, risulto connesso.

4) Non riesco ad accedere alle configurazioni del router tramite browser.
Anche questo è molto strano. Mi chiede la password ma la schermata non viene caricata.

5) la cartella:

Codice: Seleziona tutto: gatolopez70@gatolopez70-laptop:~$ ls /etc/NetworkManager/system-connections/ Auto deneb Auto deneb2

Contiene le impostazioni del vecchio router dlink con cui continuo a non avere problemi (di connessione ma lì è il router ad essere mezzo partito) ma non associa il router sitecom.
Che, invece, viene associato con 11.10:

Codice: Seleziona tutto: gatolopez70@gatolopez70-laptop:~$ ls /media/f5bcaa3e-ae9f-404d-8789-63f92b5df471/etc/NetworkManager/system-connections dlink Sitecom64FAC8 automatica WebPocket. 21.6-391B Sitecom64FAC8 SpeedTouchAF4A90 gatolopez70@gatolopez70-laptop:~$

6) Unica differenza tra le due istallazioni è la versione dei driver wl0 (STA).
Nella 11.10 sono ad una versione più recente ma la versione istallata nella 10.04 risulta essere la più recente:

Provando a cambiare cifratura della password di sicurezza da Wpa-AES (che non dovrebbe dare problemi) a WEP la situazione non cambia:

Nel frattempo, basandomi su questo articolo, ho editato il file:

Codice: Seleziona tutto: /etc/NetworkManager/nm-system-settings.conf

Cambiando la stringa:

Codice: Seleziona tutto: [ifupdown] managed=true

(era settata su managed=false)

Ma non mi sembra di aver visto grossi miglioramenti...

Tutto molto strano... ::)

Perchè si colleghi al router (a modo suo) quando (e se... non lo fa sempre) inizia a chiedere la password a ripetizione devo fermare e riavviare network-manager (con sudo stop/ sudo start restart) e/o fargli cercare le reti con:
