Cant find any wireless networks

Link to this post 22 Jun 10

Actually, David, I take that back. I suspect that Madwifi is still the best option for you. Try the following if you would:


sudo apt-get install linux-headers-generic build-essential subversion

svn co http://svn.madwifi-project.org/madwifi/branches/madwifi-0.9.4/

cd madwifi-0.9.4/

make

sudo make install

And then test it with modprobe ath_pci
If the module works for you, then go ahead and update your initrd with the following command:
sudo update-initramfs -u

Let me know how that turns out for you....

OK, I did all that and it seemed to install things (albeit not on the first attempt, as I had to do some routine updates first). And it created the madwifi folder. But I still can't see how to actually access the internet wirelessly.
When I go to "edit wireless networks" there are no wireless networks on the list. At the bit where you type in the Properties, everything is greyed out except "Name" and "bssids", and I can't type in bssids. (It was exactly like this before.) I've tried some of the commands from earlier in this conversation and the outputs are nearly the same, although the output of "ifconfig -a" has a few nonzero numbers where before they were 0.

What do you think? Is it worth pursuing this line of enquiry, or do I need a new kernel?

can you include the outpu of both of these commands:
ifconfig -a
sudo iwlist scan

Actually it seems to either not have installed the madwifi driver, or you may have other / more issues. Can you also provide the output of "lsmod | grep 802". I want to see if the driver is installed and active in your kernel.

I get no output whatsoever. But when I type just "lsmod" I get the output listed below.

You mention other issues. I do have other issues with Ubuntu, but I hadn't said anything about them because I thought you had enough to deal with. But if they might be connected to this, then I might as well tell you:
- I have no sound at all.
- The screen resolution is 800x600, and the only other option is 640x480 which is even worse. (So, for instance, I can't see all of this webpage without scrolling horizontally.)
- I have trouble installing things from source, it looks like part of the gcc package is missing or something.
