Problema scheda di rete Realtek [Risolto]

[micia]

e sei certo al 100% che NetworkManager non sia in mezzo alle cosiddette?

Per accertartene prova:

Code: Select all

ps aux | grep NetworkManager


Poi controlla anche cosa c'è nel file:

Code: Select all

/var/log/wicd/wicd.log


[JamesRoot666]

Code: Select all

jamesroot666@sabayon ~ $ ps aux | grep NetworkManager
root      6304  0.0  0.1   7012  2724 ?        S    10:37   0:00 /usr/sbin/nm-system-settings --config /etc/NetworkManager/nm-system-settings.conf

sabayon jamesroot666 # /var/log/wicd/wicd.log
bash: /var/log/wicd/wicd.log: Permission denied



[micia]

/var/log/wicd/wicd.log

Se scrivi cosi il terminale penserà che tu voglia eseguire quel file, ovviamente ti nega i permessi perché è un file di testo, per vedere i suoi contenuti nel terminale puoi usare:

Code: Select all

cat /var/log/wicd/wicd.log


(concatena il file nel terminale)
oppure:

Code: Select all

less /var/log/wicd/wicd.log


leggi il file direttamente nel terminale, puoi anche scorrerlo, per chiudere premi 'q'.

ho letto un paio di cosette che mi sono uscite e in particolare mi esce scritto DHCP connection failed quando tenta di connettersi alla LAN

[micia]

Comunque, giusto per sicurezza, fai cosi, per essere certi al 100% che NetworkManager non sia fra i piedi (son pedante su questo punto, lo so).
(come root)

Code: Select all

rc-update del NetworkManager
rc-update add wicd


in questo modo sei sicuro che all'avvio viene lanciato solo wicd, e riavvia.

Poi, potresti far vedere anche a me i contenuti di quel file, giusto per sapere se ci son problemi? Se ci son chiavi di cifratura o cose simili, ovviamente, puoi toglierle, anche se non mi pare ci fossero dati di questo genere, normalmente ci son solo indirizzi locali.

[JamesRoot666]

ok ho appena riavviato comunque questo è quanto mi esce scritto:

Code: Select all

[JamesRoot666]

Ho un dubbio perchè il programma individua le reti avvia i procedimenti ma si blocca unicamente quando deve acquisire l'indirizzo IP .... può essere ( scusa la mia ignoranza da utente Windows XD) che la mia scheda di rete sia incompatibile con linux e devo cercare una sottospecie di driver??? la mia scheda è un Realtek RTL-8139 nel caso dovessi scaricare dei driver

[micia]

in Linux, in genere, se la scheda di rete non è riconosciuta non hai nemmeno l'interfaccia (che nel tuo caso è wlan0), in più non troverebbe nemmeno le reti wireless. Il fatto stesso che trovi le reti wireless significa che il kernel è in grado di "comunicare" con la scheda di rete.

a me sembra più che altro che ci sia un errore nella cifratura, dato che di solito l'errore nell'acquisizione degli indirizzi IP è dovuto a quello... Hai provato, solo per test, a disattivare la cifratura nella rete e vedere se senza cifratura si connette? Solo per provare se la scheda di rete funziona bene.

[JamesRoot666]

No mai provato come si fa???

[micia]

Dipende dal modem/router, devi entrare nelle impostazioni del router, andare nelle impostazioni della rete wireless, da lì disattivi la cifratura della rete, invece di aver la cifratura WPA, WEP, quel che è, la metti non protetta (ovviamente solo provvisoriamente) e provi a vedere se ora riesce a connettersi.
Se ce la fa, è solo un problema di impostazioni della rete, probabilmente hai immesso male il tipo di cifratura o la password, o comunque c'è solo qualche impostazione sbagliata.
Se non ce la fa, probabilmente i driver della tua scheda di rete hanno problemi, in tal caso proverei a aggiornare il kernel e vedere se il problema persiste.
