switched from Ubuntu 11.10 to Ubuntu 12.04 and now my Linksys Wireless PCI card randomly stops working

can you give the output of:

sudo lshw -C network;lsb_release -a; uname -a; sudo rfkill list

Thanks.

Also, do you dual boot? Is Ubuntuinstalled via Wubi and does the system have a makeand model?

You had an IP before:
ip=192.168.1.5

If you get an IP then run:

echo "nameserver 8.8.8.8" | sudo tee /etc/resolv.conf

Do you get web access?

Yes I have web access it seems to stop working when I search for updates or when I installed my Graphic card driver

and I ran that echo "nameserver 8.8.8.8" | sudo tee /etc/resolv.conf and nothing happened

you changed your DNS server to google's public DNS. Its easy to remember and may help.

Are there any bugs reported?

I never changed my DNS.. so I wouldnt know of any bugs

can anyone else help me out?

Well since no one would help me out.. I think I fixed MY problem.. I switched from my 5G connection to my 2.4G connection and am not having any problems

Well since no one would help me out.. I think I fixed MY problem.. I switched from my 5G connection to my 2.4G connection and am not having any problems

OK so I am still having this problem.. thought I fixed it but nope.. anyone out there still willing to help out?

If you run the Precise liveCD, does it work ok?

Yes....I am about to give up and just go back to 11.10

I made my DNS servers the same in Ubuntu and in my wireless router.. boy I hope that fixed it..

Dang.. no such luck :(

still no fix for this?
