Il mio collegamento ethernet va molto lento da quando uso il nuovo pc con ubuntu 11.04 come unico sistema operativo. Ho provato a vedere che scheda di rete ho e sembra essere la nvidia modello mcp61 (ecco il risultato di sudo lshw)

Stranamente se provo a dare il comando sudo lshw -C network non mi restituisce alcun risultato.
Come posso aggiornare i driver della scheda oppure come posso renderla più performante visto che la navigazione e lo scaricamento sono ridicolmente lenti?
Grazie dell'aiuto

Per prima cosa, quando posti pappardelle come quella di cui sopra, mettile con il tag # per rendere il post più leggibile.

In realtà non vedo nessuna scheda di rete nella configurazione che hai postato, prova a dare lo stesso comando con il sudo (ma non credo che cambi molto).
In ogni caso la tua scheda non viene rilevata dal sistema e per questo internet va lentissimo.

Controlla nel bios che sia rilevata la scheda di rete, il fatto che windows la veda non significa che nel bios sia attivata.
Poi posta l'output del comando

Grazie smurf per la risposta e scusa per l'ignoranza su come postare le "pappardelle". Come dicevo su questo pc Ubuntu 11.04 è l'unico sistema operativo, non c'è anche windows. Ecco il risultato del comando che mi hai suggerito:

Ahi! è una scheda di rete ethernet un pò rognosa!

Da terminale postami questo comando:

Codice: Seleziona tutto

udevadm info -a -p /sys/class//net/eth0

ecco il risultato di udevadm info -a -p /sys/class//net/eth0

Codice: Seleziona tutto

device path not found

Devo preoccuparmi?

No, per sbaglio sono finite due barre consecutive nel comando, tra class e net, il comando giusto è

Codice: Seleziona tutto

udevadm info -a -p /sys/class/net/eth0

prova così e vedrai.

Ah, ok! Fiuuuu! Ecco il risultato: che vuol dire???????

Codice: Seleziona tutto

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

  looking at device '/devices/pci0000:00/0000:00:07.0/net/eth0':
    KERNEL=="eth0"
    SUBSYSTEM=="net"
    DRIVER==""
    ATTR{addr_assign_type}=="0"
    ATTR{addr_len}=="6"

Cosa ti dice?

La rete funziona, forse è il modulo driver che non funziona correttamente?

Avvia Firefox e vedi se visualizza la pagina.

Se non la visulizza il problema potrebbe dipendere dal file /etc/resolv.conf che vanno messi il DNS Primario e DNS secondario del tuo Provider.

Qual è il tuo Provider? (Alice, Tiscali, Infostrada, Fastweb ... etc)

Scusa ma non capisco quello che mi chiedi; dici vedi se firefox visualizza la pagina: quale pagina? Intendi dire se naviga? Ma il problema, come spiegato dall'inizio, non è che la mia connettività sia assente quanto piuttosto che la connettività è estremamente lenta, molto di più di quanto non lo sia con un altro pc con windows xp collegato sulla stessa linea con lo stesso cavo ethernet. Il mio operatore è teleunit/okcom comunque, e quando apro firefox si apre la pagina about:startpage quella con google e logo ubuntu.

Forse sarà ridondante, ma è leggermente diverso dai comandi postati in precedenza: digita:

Codice: Seleziona tutto

lspci -v

e copia qui il risultato (ho scoperto oggi l'utilità di questa variante ;D ) ;)

Grazie mille; ecco il risultato di lspci -v
