Wireless not working: intel 5100 wifi with Debian Lenny


I'm running Debian stable (Lenny) on my wife's Acer Aspire 6930 with an intel 5100 wireless card, and in order to get the wifi recognized I had to install a newer kernel than the stock one available in Lenny. Lenny backports has the 2.6.29/30/32 kernels, any of which should work for this wireless card. 2.6.30/32 created some serious problems mixed with Lenny and this laptop, and 2.6.29 in Lenny backports has uninstallable headers. What I wound up doing is compiling a 2.6.29 kernel and the appropriate headers from source. Works fine, and I know that I can install kernel modules... Virtualbox is running as nice as you please.

Except that the wireless card won't detect any networks. It is recognized by the OS as wlan0, but it can't see my wireless networks. here is the wlan0 part of my ifconfig:

Code:
wlan0     Link encap:Ethernet  HWaddr 00:16:ea:77:95:b0
          UP 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)
This laptop is running KDE 3.5 with Knetworkmanager.

Oops... I meant to put that in the original post and forgot to. Sorry. the firmware is onboard, and I've run the following commands:

modprobe iwlagn
ifconfig wlan0 up

No error messages, but no wifi either. I'm sure that i'm missing something obvious... I don't use wireless very much.

Take a look at http://wiki.debian.org/iwlagn

Add the backports.org repo, http://www.backports.org/dokuwiki/do...d=instructions

aptitude update && aptitude install debian-backports-keyring && aptitude -t lenny-backports install firmware-iwlwifi;
also need to install a newer kernel from backports. aptitude search linux-image

Can also search for backport packages at http://www.backports.org/dokuwiki/doku.php?id=packages

Check my original post... I already did that stuff. I had to compile a kernel manually; the 2.6.30/32 kernels cause a darkscreen problem with Lenny on this laptop (I wish to god my wife would just let me re-install Squeeze) that I couldn't chase out, and the 2.6.29 kernel in backports is missing headers. But anyway I've got a newer kernel onboard and the firmware installed... still no wifi.

Does running iwconfig show anything?

Take a look at /etc/network/interfaces and make sure your wlan is listed.

If you have a wired connection you might try using wicd rather than the knetworkmanager.

Is the hardware switch in the ON position?

Apparently it's not:

Code:
elizabeth:~# cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
allow-hotplug eth0
iface eth0 inet dhcp
Can I just do a duplicate of the eth0 entry only with wlan0?

@AlucardZero: yes, its turned on.

Duplicating the eth0 entry for wlan0 solved the prob. Thanks guys!
