View Full Version : [ubuntu] Big Wireless problem

June 27th, 2008, 08:18 PM
Hey all
At the right of the top panel there is the networking symbol-->before when I clicked on it I would get a drop down with check boxes 'wired network','wireless network', manual configuration etc.
Well now I only get 'wired network' and 'manual configuration' My wireless options have just disappeared!

With a right click I now have the tick option by Enable Networking but again that option for wire less has now disappeared.

I dont really know what I did, but I could do with getting internet back on my other computer-is there some way I can get these options (and wireless) back?

Id rather not have to reinstall---> Oh yeah I'm using Hardy

Cheers All

Please provide the output of:

lshw -C Network
iwlist scanning

If you can't get any Internet connection on that machine (i.e. you can't plug in with a wire temporarily), then it's probably hard for you to copy all of the output of the commands above by hand. If that's the case, let me know and I'll help you to work around that so you don't have to copy by hand.

Cheers for the post.
I have got internet wireless working at the minute---> better than it was before, but only through connecting manually. I think for now thats ok to keep me going but it would be good to get it connecting automatically.

The result of those commands are:

Is absolutely massive- do you still want this?

Thanks- By the way these commands were run while i was connected manually to my wireless

If you can connect from the command-line, then it sounds like the problem is with Network Manager, not your card. I'm not sure why NM would have broken suddenly, but it could have been a poorly tested update. You might try using wicd (http://wicd.sourceforge.net) instead; it will do everything that NM can, but more reliably, in my experience.
