View Full Version : [ubuntu] [SOLVED] Wifi after this morning's updates

Okay guys, seems like this one is a reasonably fairly oft presented concern. I installed the latest updates this morning and then, upon restarting my computer, had my wifi vanish in a puff of ethereal smoke.

How do I restore it? I am using the ath_pci drivers for the AR5007EG wifi card, but have no device to scan with (only 'lo' and 'eth0'). After running 'lshw -C network', the computer lists it as a device onboard, but doesn't assign it a logical name (unlike the wired connection). I can't run through Kevdog's tutorial (which has worked in the past) since I don't have the device name.

Where do I go from here?

Cheers!

Here it is:

I've also had a bit of trouble with the wired LAN not working (I've just had to type this out as a result). Haven't looked into it at all, couldn't be bothered with that at this stage, but I am wondering if the two are linked.

what did you to previously to make the card work, or did it work "out of the box" as they say?

If I could remember that, I would have done it! Ha! Seriously, though, I can't for the life of me remember. I have the madwifi files on my comp to change the computer's perception of my card from AR5006 to AR5007, but that's about all I know. I have also run the tutorial from Kevdog numerous times keeping up with changes in the IPs and wifi networks at work (and at home). But there seems to be a step (or two/three/many) missing between the two!

the recent update you received was a kernel update. so any compiling of anything you did, will have to be done again, so it works for your new kernel.

Quite correct. You will have to run the command 'make clean' first, before you re-run 'make' and 'sudo make install.'

Where/when will I have to run the command 'make clean' etc.? What does that even do?

Make sure that you have the linux-generic package installed. This will pull the modules package for your kernel if missing.

I have the madwifi files on my compDid you not build a module previously, in this directory, with 'make,' and 'sudo make install?' You will need to go through this process again, but first add the command 'make clean.'

Since the module was previously built specifically for a kernel that has been superceeded, we need to clean out the old parts and build new parts for your new kernel.

Thanks for your help guys. It'd been a while since I did all that 'make' and 'make install' stuff. I appreciate the link, too. I've now saved that page on my comp for future reference! Kudos to all!
