I am using a Dell XPS L702x and I am using Ubuntu 10.04 because I need to use f77 (don't ask) and I wasn't able to get it working on later versions of ubuntu.

I cannot use the wifi at all. I have tried to fix it and have had limited success (changed the output from rfkill list all from Hard blocked: yes, to hard blocked: no).

Here is the output from rfkill list all

aodhan@aodhan-laptop:~$ rfkill list all
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
1: dell-wifi: Wireless LAN
Soft blocked: no
Hard blocked: no
2: dell-bluetooth: Bluetooth
Soft blocked: no
Hard blocked: no

Here is the output from iwconfig:

aodhan@aodhan-laptop:~$ iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

pan0      no wireless extensions.

And here is the output from ifconfig -a:

aodhan@aodhan-laptop:~$ ifconfig -a

Please help me!

Thank you in advance.

Edit:

Further info - this is a dual install with a windows 7 system as the other option. However, I can't access that until tomorrow (I won't have access to the windows 7 disc until then, and grub isn't letting me load it). Therefore, I can't be sure whether it still works on that or not. It used to, though.

It looks like the solution to your problem is to update your kernel to 2.6.38

Quote from the theunsheydenrych from this forum post about the problem

I can confirm that the wifi is working after i installed the 2.6.38 kernel.

I have a Dell XPS 17 702x , with Ubuntu 10.04 (Lucid Lynx)

You helped a lot in sorting this issue out, thanks

to do this you will need to add a ppa and update the kernel from it

open a terminal and enter this command

sudo add-apt-repository ppa:kernel-ppa/ppa

then update..

sudo apt-get update

finally install the kernel and headers..

sudo apt-get install linux-headers-2.6.38-1-generic linux-image-2.6.38-1-generic

hopefully this will get your wi-fi up and running
