I am on the road and with my Dell Inspiron 1200 and this morning up date of Feisty Fawn asked me to restart my computer and when it did my wireless card will no longer connect to the router. I am borrowing a laptop to write this. How can one undo an update? So I can get back online? I really prefer to use Ubuntu and I hate like hell to put the XP hard drive back in the machine. But I am back on the road soon and need Internet access. Can anyone tell me how to get my laptop back on line? Oh, the installation worked flawlessly for over a month connecting to all the AP along the way. There is nothing wrong with the router because this computer is accessing it.

Thank you, Tim

Hi Tim,

What did the update install? Did it install a new kernel? If so, you probably need to recompile the wireless drivers. What is the make and model of your wireless card? Have you tried reverting to an older kernel in Grub?

Thank you for writing. I really need to be more careful and read what it being updated but in this case I didn't. Somewhere there must be a log telling what was updated but I don't know where that would be.

I went through a rather lengthy process given in the howto mentioned in my original message. That had me clean all tracts of ndiswrapper off the machine before doing anything. The reinstall ndiswrapper, download the Dell drivers . . . The wireless card is a Broadcom Corp BCM4306

Next time I reboot I will try to catch grub and find the older kernel. This makes me wonder if I should accept the updates anymore . . .

Tim

Accept updates, but make sure you know what you're updating, as they sometimes break!! I would suggest using ndiswrapper and not the bcm43xx driver for wireless. I have that chipset too, and have found ndiswrapper to be more stable.

I thought ndiswrapper used the windows card drivers. I thought I was using ndiswrapper following the instructions found in http://ubuntu1501.blogspot.com/2007/...dell-1501.html .
Anyway, until I get back "home" I doubt I am going to do much but gather information on this problem as I can use command lines to get online. It is really interesting learning the ins and outs of Linux . . . even if I am on the very bottom of the learning ladder.

ndiswrapper does use the windows drivers yes. Is that what you are using then? I'd suggest removing it altogether and then try updating ndiswrapper to the next stable version. If that doesn't work try downgrading to an older version. I use v1.38 and that works flawlessly for me with the BCM43xx chipset on my HP laptop. Surprisingly (for me at least), when I install a new kernel, I don't have to recompile the ndiswrapper module but i don't know why this is. Don't use the version you download with apt though, that didn't work for me, compile from source and it should end all your wireless woes. Make sure you remove all traces of it first though, and blacklist your bcm43xx. Follow instructions here. http://www.ludreb.plus.com/ubuntuguide.html#6
