problems with iwl3945

Hi guys, I'm having trouble in trying to setup wireless network connection. It won't connect
to the wireless network.
I guess its a problem with iwl3945.

    The ifconfig:

 ifconfig -a
eth0      Link encap:Ethernet  HWaddr 00:1C:23:F9:D6:AA  
          inet addr:192.168.1.66  Bcast:192.168.1.255  Mask:255.255.255.0

          TX packets:7 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:1337 (1.3 Kb)  TX bytes:1023 (1023.0 b)
          Interrupt:17 

lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

wlan0     Link encap:Ethernet  HWaddr 00:1E:8C:01:3C:80  
          BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

wmaster0  Link encap:UNSPEC  HWaddr 00-1E-8C-01-3C-80-00-00-00-00-00-00-00-00-00-00

          collisions:0 txqueuelen:1000 
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

and

# dhcpcd wlan0
err, wlan0: ioctl SIOCSIFFLAGS: No such file or directory

Thanks...:)

Re: problems with iwl3945

That error in particular doesn't ring a bell, but I would suggest using netcfg2 to make your network connections. It's the default Arch tool and it works perfectly for my iwl3945 driver, even for WPA2 security. There is a great wiki on how to use it properly:

Re: problems with iwl3945

A search on this forum has returned some exact hits. Try the fallback image in grub and see if it works. If yes, you might need to stop using autodetect in rc.conf and specify the needed modules manually.

I have a similar problem, but it is still not solved (SIOCSIFFLAGS: operation not permitted with prism54)

Re: problems with iwl3945

Hi again,
I tried with both of the suggestions but I keep getting similar errors
when I do netcfg2 myprofile
i get:

netcfg2 myprofile
:: wep-static.example up                                                 [BUSY] SIOCSIFFLAGS: No such file or directory
wlan0     Interface doesn't support scanning : Network is down

wlan0     Interface doesn't support scanning : Network is down

wlan0     Interface doesn't support scanning : Network is down

wlan0     Interface doesn't support scanning : Network is down

                          - Network unavailable                          [FAIL]

And when I try dhcpcd wlan0 I get:

 dhcpcd wlan0
err, wlan0: ioctl SIOCSIFFLAGS: No such file or directory

I also try the iwl3945 module unloading-loading on boot to see if it worked
(saw it on another post with similar problems), and it didn't work:(

Re: problems with iwl3945

That module is already available in the kernel since 2.6.24, so you don't need to load it seperately.

Other that that, I have no clue: On my fathers laptop, I just had to configure netcfg2 and all was well.

Re: problems with iwl3945

OK,don't hit me, but are you sure your kill switch (wifi off switch) is in the right position. I always get these errors when mine isn't. If that's OK, then I'd think you need to do a "sudo ifconfig wlan0 up" and to associate with a basestation using iwconfig or wpa_supplicant, before you can successfully obtain an address with dhcpcd.

netcfg2 is terrific, but if one's having problems, it's easiest to try to get things working manually first, or if you can't, to find out at what stage the obstacle is...

Just now realized abijr reports problem solved...

Re: problems with iwl3945

I think that error occurs when the driver can't find the firmware. Do you have core/iwlwifi-3945-ucode installed?
