10 Apr 2011 Enable wireless in Ubuntu 11.04 Beta1 on a HP 8540p
This post is a short description on how to enable the wireless interface on my HP 8540p in Ubuntu 11.04 Beta 1 (Natty Narwal).
A little information about the wireless interface
# lspci ... 44:00.0 Network controller: Intel Corporation Centrino Advanced-N 6200 (rev 35) ... # lspci -n ... 44:00.0 0280: 8086:4239 (rev 35) ...
According to the Debian GNU/Linux device driver check page this wireless interface should use the iwlagn kernel module.
After searching a little i found this forum thread on Ubuntuforums that described this problem quite well.
A short description of the problem is that there is some problems with Wireless N on the iwlagn Intel drivers preventing the interface to function properly.
The solution to the problem should also work on Ubuntu 10.04 and 10.10.
First we determine if the iwlagn module is present on the system
# lsmod | grep iwlagn iwlagn 333500 0 iwlcore 167503 1 iwlagn mac80211 294370 2 iwlagn,iwlcore cfg80211 178528 3 iwlagn,iwlcore,mac80211
You can proceed if the result after running the command contains the iwlagn module
Now we can disable the Wireless N feature in the Intel iwlagn kernel module
# gksudo gedit /etc/modprobe.d/intel_11n_disable.conf
Add the following line to your newly opened file
options iwlagn 11n_disable=1
Save and exit the file.
Unload and load the kernel module
# sudo modprobe -r iwlagn # sudo modprobe iwlagn
Update initramfs before you perform a reboot
# sudo update-initramfs -u
After a reboot has been performed it’s time to check the wireless interface.
The Wireless network state on my HP 8540p
# sudo lshw -c network
*-network DISABLED

resources: irq:48 memory:d3300000-d3301fff
My wireless interface was not enabled so I had to UP it myself.
# sudo ifconfig wlan0 up
# sudo ifconfig wlan0
wlan0 Link encap:Ethernet HWaddr 00:aa:bb:cc:dd:ee
UP BROADCAST MULTICAST MTU:1500 Metric:1

TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
Now when I perform a lshw command
# sudo lshw -c network
*-network

resources: irq:48 memory:d3300000-d3301fff
All I had to do now was to check “Enable Wireless” from the Network menu located on top right of the Unity window next to the clock.

You can use lspci -n to analyce what hardware is on your system. My new laptop a HP EliteBook 8540p gives the following output:
00:00.0 0600: 8086:0044 (rev 12) 00:01.0 0604: 8086:0045 (rev 12) 00:16.0 0780: 8086:3b64 (rev 06) 00:19.0 0200: 8086:10ea (rev 06) 00:1a.0 0c03: 8086:3b3c (rev 06) 00:1b.0 0403: 8086:3b56 (rev 06) 00:1c.0 0604: 8086:3b42 (rev 06) 00:1c.1 0604: 8086:3b44 (rev 06) 00:1c.3 0604: 8086:3b48 (rev 06) 00:1c.7 0604: 8086:3b50 (rev 06) 00:1d.0 0c03: 8086:3b34 (rev 06) 00:1e.0 0604: 8086:2448 (rev a6) 00:1f.0 0601: 8086:3b07 (rev 06) 00:1f.2 0106: 8086:3b2f (rev 06) 00:1f.6 1180: 8086:3b32 (rev 06) 01:00.0 0300: 10de:0a2c (rev a2) 01:00.1 0403: 10de:0be2 (rev a1) 44:00.0 0280: 8086:4239 (rev 35) 45:00.0 0c03: 1033:0194 (rev 03) 46:06.0 0c00: 1180:0832 (rev 06) 46:06.1 0805: 1180:0822 (rev 25) 46:06.2 0880: 1180:0843 (rev 14) 46:06.3 0880: 1180:0592 (rev 14) 46:06.4 0880: 1180:0852 (rev bb) 46:06.5 0607: 1180:0476 (rev ff) ff:00.0 0600: 8086:2c62 (rev 02) ff:00.1 0600: 8086:2d01 (rev 02) ff:02.0 0600: 8086:2d10 (rev 02) ff:02.1 0600: 8086:2d11 (rev 02) ff:02.2 0600: 8086:2d12 (rev 02) ff:02.3 0600: 8086:2d13 (rev 02)
Copy the result from the above command and visit the address Debian GNU/Linux device driver check page and paste it into the window.
In my case the result was presented like this

This makes it easier to determine which device drivers I’m missing and might have to compile for the kernel.
