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

And finally, the output from lspci:

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.
