Router wireless+WPA [RISOLTO]

Burroughs · Messaggio da **Burroughs** » mer 31 gen 2007, 15:50

Utilizzo da quasi due anni e mezzo un router wireless 3Com, modello 3CRWE754G72-A, che implementa anche un access point.
Nella mia piccola WLAN (un portatile ed un fisso e, di quando in quando,un palmare) ho deciso di provare la criptazione WPA, per ovvi motivi di sicurezza.
Ah, dimenticavo, sul portatile ho il chip wi-fi Intel IPW2200BG, sul fisso una chiavetta USB US Robotics che faccio andare con ndiswrapper.
Premetto che col WEP non ho mai avuto problemi di sorta.
Bene, sul router scelgo WPA-PSK come sistema di gestione delle chiavi, ne imposto una e poi vado ad installare sulle macchine interessate wpa_supplicant, versione 0.5.4 (compilato da sorgenti).
Vado a provare il tutto.
Lo script che utilizzo sul portatile, per esempio, è questo:

Codice: Seleziona tutto

echo "Imposto le proprietà della connessione"
iwconfig eth1 essid "essid_name"
iwconfig eth1 mode Managed
iwconfig eth1 channel 10
echo "Riconfiguro la tabella di instradamento"
route add -net 192.168.1.0 netmask 255.255.255.0 dev eth1
route add default gw 192.168.1.1 eth1
echo "Carico la configurazione di wpa_supplicant"
cp /root/backup/config_files/wpa_supplicant.conf_myconf /etc/wpa_supplicant.conf
echo "Entro nella WLAN Pincopalla"
wpa_supplicant -D wext -c/etc/wpa_supplicant.conf -ieth1

Fatto questo, noto che o il portatile o il fisso, molto più spesso di quanto non si pensi, non riescono ad accedere alla rete: dalla shell viene visualizzato un messaggio di disconnessione con relativa rimozione delle chiavi.
Non solo, lo stesso problema viene anche avvertito dal mio palmarino, il mitico Nokia 770.
Cosa faccio allora?
Riavvio il router e tutto riprende a funzionare.
Convinto di aver combinato qualche sbaglio nella mia configurazione, passo a fare dei test con Windows: bene, anche in questo caso, di tanto in tanto, non si riesce a pingare il router, sintomo che c'è qualcosa che non va.
Ora, io ho aggiornato il firmware del router all'ultima versione disponibile e, come scrivevo prima, il router per il resto sembra andare.
L'unico problema riscontrato in questi anni è stato uno sbalzo di tensione che mi ha fatto saltare una porta Ethernet ma per il resto tutto ok.
Qualcuno di voi ha avuto un'esperienza simile alla mia?

quando lanci wpa_supplicant attiva il debug (-d) e vedi che ti dice..

Beh, il debugging mi dice questo (chiedo scusa in anticipo per la lunghezza del listato):

In pratica, è possibile (per il chip wifi del mio laptop) associarsi all'access point ma non autenticarsi.
Ho provato compilando anche la versione più recente di wpa_supplicant, la 0.5.7, ed anche il pacchetto precompilato da Pat (corrispondente alla 0.4.9), ma la situazione non si sposta di un centimetro.

io ho la tua stessa scheda wireless e la mia situazione è così:

- router netgear dgb834g
- driver ipw2200 del kernel 2.6.19.2
- wpa_supplicant 0.4.9

il ruoter è configurato per wpa-psk, dhcp attivo e controllo del MAC.
a me funziona tutto!

tu che versioni usi?
sei sicuro di aver messo la giusta chiave in psk nel wpa_supplicant.conf?

Il modello del mio router lo trovi più in alto.
Rispetto a te, utilizzo i driver ipw2200 "esterni", quelli cioè forniti dalla community, guidata da Intel, che li sviluppa.
L'unica cosa strana che ho notato è che con i "nuovi" driver installati (dico nuovi perché sono di un mese fa), versione 1.2.1, ho i problemi di cui sopra, con la vecchia versione che utilizzavo, la 1.1.3, tutto ok.
Io sospetto un bug.

Anch'io qualche mese fa ho avuto problemi simili: fino a Dicembre aveva funzionato tutto poi, verso la fine del mese, avevo spesso difficolta' a connettere i miei pc al router wireless, sia con Linux che con WIndows.
Dopo vari mastrussamenti ho finalmente capito: tutta colpa di Babbo Natale!

E si', perche' quel sant'uomo ha portato ad uno dei miei vicini di casa un router wireless e anche lui usava per la sua rete il mio stesso canale (intendo il vicino, non Babbo Natale!)

Soluzione: impostata la scelta del canale su AUTO, sia sul router che sui PC e tutto ha ripreso a funzionare!

Tu usi un canale fisso? Controllato che nelle vicinanze non ci sia un'altra wireless? (anche se funziona su frequenze vicine alle volte puo' dare fastidio)

Ciao,
Mr Hyde

Vorrei poterti dar ragione ma, anche se uso un canale fisso, tutte le altre macchine della mia WLAN vanno in rete tranquillamente, compreso il serverino Slack su cui si trova un dongle wifi US Robotics.
Penso proprio sia un bug della versione 1.2.1 dei drivers del chip wifi.

Mercoledì scorso, 4 aprile, è stata rilasciata la versione 1.2.17 del subsystem ieee80211.
Bene, ho disinstallato la precedente versione, la 1.2.16, installato la nuova e... voilà, il problema è scomparso in un attimo.
Da tutto ciò deduco che la 1.2.16 fosse cannata.
Per il download della 1.2.17, fate il download da qui.
