 |
|
salve
ho un problema con la mia scheda di rete
| Code: | 06:00.0 Network controller [0280]: Broadcom Corporation BCM4311 802.11b/g WLAN [14e4:4311] (rev 01)
|
praticamente reinstallando gentoo, nella compilazione del kernel iniziale funzionava tutto la presenza di wlan0 [/b ]c'era.
poi ho fatto delle altre modifiche al kernel e devo aver disabilitato quacosa involontariamente, sono uscito dalla configurazione senza salvare le impostazioni del kernel da quel momento la sche da wifi e scomparsa
| Code: | ifconfig -a
eth0 Link encap:Ethernet HWaddr 00:16:d4:f0:48:60

e questo[b] /etc/init.d/net.wlan0 start
| Code: |
mattylux linux # /etc/init.d/net.wlan0 start
* Bringing up interface wlan0
* ERROR: interface wlan0 does not exist
* Ensure that you have loaded the correct kernel module for your hardware
* ERROR: net.wlan0 failed to start |
qualche conscilglio??

Rivedere la configurazione del kernel. Sezione driver. Ricompilare e risistemare.
Ricompilato il kernel è buona cosa ricompilare i moduli.
Se sei poco pratico usa genkernel --menuconfig e non fare l'eroe; gli eroi sono sono imbecilli (per lo più morti), fumo negli occhi o mistificatori, quasi sempre tutte e tre le cose.
Controllare con un bel dmesg | esempio: | ath5k 0000:02:07.0: PCI INT A -> GSI 22 (level, low) -> IRQ 22
ath5k 0000:02:07.0: registered as 'phy0' |
cosa viene caricato e con | lspci -vvs 02:07.0: | 02:07.0 Ethernet controller: Atheros Communications Inc. Atheros AR5001X+ Wireless Network Adapter (rev 01)

Interrupt: pin A routed to IRQ 22
Region 0: Memory at fe7f0000 (32-bit, non-prefetchable) [size=64K]
Capabilities: [44] Power Management version 2
Flags: PMEClk- DSI- D1- D2- AuxCurrent=375mA PME(D0-,D1-,D2-,D3hot-,D3cold-)
Status: D0 NoSoftRst- PME-Enable- DSel=0 DScale=2 PME-
Kernel driver in use: ath5k |
se la scheda è correttamente rilevata (possibile che un banale urto l'abbia spostata, fidati, mi ha fatto impazzire per una settimana ed è bastato usare un cacciavite a stella).
In alternativa | /etc/conf.d/udev: | | persistent_net_disable="no" |
| Code: | | rm /etc/udev/rules.d/70-persistent-net.rules |
potrebbero essere soluzioni.
Da provare nell'ordine che ho indicato. I cocci sono tuoi ovviamente.

mi pare che ti manchi il | esempio: | | Kernel driver in use: ath5k |
che ho io e comunque al massimo dovresti vedere cosa riporta | Code: | | dmesg | grep 06:00.0 |
il tail non è utile.
Mi pare sempre che ti sei scordato il driver ma nel dubbio ti ho indicato tutte le prime possibilità di rogna e relativi rimedi.
Rivedere la configurazione del kernel, ricompilarlo (casomai potresti metterla builtin la scheda) e controllare i moduli, che siano tutti al loro posto.
[OT]gli output e le configurazioni, per chiarezza, è meglio riportarli con | Code: | | [code="comando"]output[/code] |
od in alternativa | /path/file wrote: | | contenuto |
| Code: | | [quote="/path/file"]contenuto[/quote] |
se vuoi fare uso di colori, dimensione carattere etc. [/OT]

risolto ho ricompilato da capo il kernel eliminando quello vecchio e tutto e funzionanto alla perfezione...
avevo disabilitato io per sbalgio qualche modulo..

 capisco che un errore di battitura possa scappare ma... povera lingua italiana... oggi siamo proprio in tema... una prece
