Intel 5100 AGN on Ubuntu 10.04

For me this is a critical bug, because I’m frequently using my Lenovo SL400 on wireless networks. The problem is related to Intel 5100 AGN on Ubuntu 10.04. It connects fine on the start but degrades until it eventually disconnects to the wireless access point. Sometimes I have to reboot to be able to connect to the wireless network again. I’ve been experiencing this  until I’ve found this workaround (click here).

Here’s the fix (But it’s very ugly):

1. Create a new modprobe configuration, let’s call it options.conf

$sudo vi /etc/modprobe.d/options.conf

2. Add the following code:

options iwlagn 11n_disable=1 11n_disable50=1

3. Reboot the system and check if it fixes your Intel 5100 AGN wireless device’s problem.

4. Done.

    Thnx! I couldn’t even connect with my Pavillion dv5 to Digicom 54R access point.
    I found hundreds of post on different forums but no way.
    Now with this workaround it’s working, it’s stable and it’s fast.
    Thnx again!

      I think your wireless network is currently deactivated, or you haven’t properly installed the proper driver for your wireless network device.
