[SOLVED] Iwconfig not working

Hi all, i'm a new arch-user, and i'm trying to set up my wireless card. I've used it with gentoo and ubuntu with success, so, like i did in that 2 distributions, i installed ndiswrapper and loaded the right drivers. The card is now seen by the system as wlan0, but i can't set anything using iwconfig.
For example, this is iwconfig output:

disabled@Dario:~$ iwconfig wlan0
wlan0     IEEE 802.11b  ESSID:off/any
          Mode:Auto  Frequency:2.412 GHz  Access Point: Not-Associated
          Bit Rate:11 Mb/s   Tx-Power:20 dBm   Sensitivity=0/3
          RTS thr:off   Fragment thr:off
          Power Management:off
          Link Quality:0  Signal level:0  Noise level:0
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

When i try to set essid (but also channel or mode) i don't get any error message, but iwconfig don't change them:

disabled@Dario:~$ sudo iwconfig wlan0 essid default
disabled@Dario:~$ iwconfig wlan0
wlan0     IEEE 802.11b  ESSID:off/any
          Mode:Auto  Frequency:2.412 GHz  Access Point: Not-Associated
          Bit Rate:11 Mb/s   Tx-Power:20 dBm   Sensitivity=0/3
          RTS thr:off   Fragment thr:off
          Power Management:off
          Link Quality:0  Signal level:0  Noise level:0
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

Any ideas? Thanks in adance smile

Re: [SOLVED] Iwconfig not working

Thanks for the reply smile

This is the output of iwlist scanning:

disabled@Dario:~$ iwlist scanning
lo        Interface doesn't support scanning.

eth0      Interface doesn't support scanning.

wlan0     Scan completed :

So, it sees my ap, but still i can't connect to it, even with:

iwconfig wlan0 ap 00:80:C8:AD:17:70

Re: [SOLVED] Iwconfig not working

yeah it sees the ap, but 

Quality:0/100  Signal level:-51 dBm  Noise level:-256 dBm

it couldn't reach it...maybe it wants a stable connection to executing command like setting the essid or anything else...with other distro have you still a strong connection?

/me is going to work for the first day after the summer break  :evil:

Re: [SOLVED] Iwconfig not working

This is the result of iwconfig started from ubuntu:

wlan0     802.11b linked  ESSID:"default"  
          Mode:Managed  Frequency:2.437 GHz  Access Point: 00:80:C8:AD:17:70

          Power Management:off
          Link Quality:97/100  Signal level:-37 dBm  Noise level:-253 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

The link is strong sad

Can it be a kernel problem?

Re: [SOLVED] Iwconfig not working

Sounds like a module problem... what module are you using?

Re: [SOLVED] Iwconfig not working

If with module you mean the wireless card module, i use ndiswrapper with the same windows driver on both arch and ubuntu. Arch version is 1.23.

Otherwise i didn't understand what do you mean smile

Re: [SOLVED] Iwconfig not working

Well, you said you used ndiswrapper before, but I don't see ndiswrapper in ubuntu's list.

Can you post the output of "lspci", and also check if "ndiswrapper -l" reports "hardware present" or not.

Anyhow, here's my lspci:

and ndiswrapper -l:

As you see, it goes well smile

Re: [SOLVED] Iwconfig not working

Oddly enough, it looks like ubuntu is using the "r818x" driver... which is some Realtek wireless driver.  Try removing ndiswapper and loading that one (assuming it's part of the stock kernel).

Also note, some modules load wireless devices as "ethX" devices, which sucks... wireless != ethernet.  Foolish module developers!

Re: [SOLVED] Iwconfig not working

Well, i'm gonna leave for 2 days now, so i won't be able to try that r818x you mentioned, but i will as soon i return wednsday evening smile

I'm sure ndiswrapper loads my wireless device as wlan0 cause i've seen that in the dmesg after loading ndiswrapper modue smile

ndiswrapper version 1.23 loaded (preempt=yes,smp=yes)
ndiswrapper: driver netdlwl (D-Link,05/23/2003,5.140.0523.2003) loaded
ACPI: PCI Interrupt 0000:00:06.0[A] -> GSI 17 (level, low) -> IRQ 20
ndiswrapper: using irq 20
wlan0: vendor: 'D-Link Air Wireless LAN Adapter                                                 '
wlan0: ethernet device 00:40:05:3e:7b:a0 using NDIS driver netdlwl, 1186:3300:1186:3301.5.conf

Re: [SOLVED] Iwconfig not working

Well, i finally made it smile

After some troubles i was able to compile the rtl8180 driver (this bug is very important) and with that i was able to use my wireless card. Thank you all.

I still can't remember when i installed that driver on ubuntu, cause i was sure to have installed only ndiswrapper, but it doesn't matter tongue[/url]
