Hi, I have a similar problem, I have a Dell studio 1747 wireless working great before upgrade, the driver was gone upon reboot after upgrade, I got the driver installed, but now network manager shows no networks to connect to my chipset is bcm43224
Thanks!

bump :(

The funny thing is, I had wireless, turned it off and it just won't come back on. I've pressed/clicked all the regular stuff.

Am using an HP Pavillion DV2 .. never one of Ubuntu's favorite models I think.

I just upgraded to 2.6.35-22-generic.

Would it help if I install the B43 driver, I wonder? Currently using the STA BCM4312.

Otherwise, Maverick's rather demure so thanks to all and sundry for the new toy.

i fixed it by putting the ucode back in the firmware directory in lib and getting rid of conman

when you update your kernel you have to use the backport driver part of the software updating and sometimes you have to put ucode back in the firmware directory i spent hours trying to figure that out it would be nice if there was a way to do it with out that but i guess it's not feasible or a priority. you could probably write a script that could automate that but i agree it gets confusing. also if that does not work try manually installing drivers i remember seeing a tutorial on that here somewhere and there are always windows driver wrappers but they are buggy in my experience. if none of that works someone else might think of something or you can Google it to see if someone else with your hardware and situation has a fix.

I was able to solve this issue on my mini by simply employing the Synaptic Package Manager as follows:
In Synaptic, remove the bcm43 driver which is, in Synaptic, 'firmware-b43-installer' the same time you install 'firmware-b43-lpphy-installer'. If you don't the system seems to get confused and reverts to the original driver driving you up the wall.... again. Good Luck !!! Hope this works.... :smile:
