Question Unable to get wireless to work on HP DV7-1541nr running Lucid Lynx 10.04


I can't seem to get wireless to connect to anything. It seems to be working, but won't talk to anyone. I have tried a number of things from other suggestions, including recently removing the network-manager (which was a mistake) to replace it with wicd. Having removed it, I now have NO networking on my laptop.

I would really appreciate some suggestions to try. Here's some command output (all done prior to removing network-manager):

I assume the problem is with the driver for the Atheros card not being functional. I have tried to research using Madwifi, but it seems outdated and replaced. I have considered wicd, but now I need to download it to another machine and bring it over on a flashdrive or reinstall network-manager. Appreciate any suggestions.

I can see from this output that you use the following kernel module:

Quote:
tom@Owl:~$ sudo lspci -nnvv (edited down to just network info)

Kernel modules: ath5k
But according to: http://wireless.kernel.org/en/users/.../ath5k/devices

You will see that the AR5001 chipset is not supported by that driver.

Alternatively, I recommend you checking this case:

https://help.ubuntu.com/community/Wi...Driver/Atheros

Hope it helps !

Appreciate the link, but reading a bit further the list is just cards/chips which are known to work. There's an open bug report on the AR5001 card under the ath5k driver on the same site, which means it's probably intended to work.

I appreciate the link. I tried it early on, but I think I'll try it again just in case my fiddling has helped, or I've gotten smarter about what to look for.
