Wireless not working in Ubuntu 12.04

Code for iwlist scan

Code:

lo        Interface doesn't support scanning.

eth1      Interface doesn't support scanning.

eth0      Interface doesn't support scanning.

So,I have ubuntu 12.04 64 bit installed. As I try connecting to a wireless connection, it asks for credentials and then every 2 minutes it asks for credentials again. Just doesn't connect. Please let me know, if more info. is needed. Would greatly appreciate any help.

Hello,

The op has a broadcom card. He/she would be better off with what is found in post 2 and later of this thread.

Ok everybody please try this if you are still having the problem, i work on computers and we had lots of Ubuntu users having this problems today, we found a program on Ubuntu Software Center called Windows Wireless Drivers, it lets you install a windows wireless driver for your wireless card. Worked on all the computers we had in. Please try it.

**lossman29** · April 28th, 2012

Tried the method mentioned in the other thread for the broadcom driver but to no avail. keeps asking me for credentials every 5 minutes. Gets stuck there.

How do you use the windows wireless driver tool? Do you need to deactivate the broadcom driver and remove all installed packages first?

Also asks for an inf file? Where do you find that?

**wildmanne39** · April 28th, 2012

Hi, you do not need ndiswrapper and it is the last option you want to use.

Did you try this link as recommended by
bkratz?
http://ubuntuforums.org/showthread.php?t=1879096
if so please post

Code:

lsmod

again so we can see what is loading now and:

Code:

lspci -nnk | grep -iA2 net
iwconfig
rfkill list all

Thanks

**lossman29** · April 28th, 2012

I tried everything in the link recommended by bkratz but it keeps getting stuck at asking credentials.

Posting the codes again.

Hi please do:

Code:

echo "blacklist brcmwl" | sudo tee -a

make sure you have installed all updates then run:

Code:

sudo apt-get install --reinstall bcmwl-kernel-source

Then reboot.
Thanks

Thanks a lot Wildmanne.
The wifi connects but after entering credentials for the 1st time, it gets stuck and keep asking me for credentials every 2 minutes till I hit cancel. Problem not yet solved.

Any other suggestions?
