I found the link you have me last night. Its seems like it found the adapter but I can't connect to any networks

Hi,

Did you follow all the instructions in http://ubuntuforums.org/showpost.php?p=6077792&postcount=72?

Did you succeed in manually downloading and installing b43-fwcutter and also the Broadcom firmware files in Ubuntu?

Did you reboot your pc afterwards and then retest wireless?

Regards,

Mark

I did, I dont have a wired connection. everything seems to be working fine. the last few steps it wouldnt take any of the comands so i modify them. it wont find any networks at all. i been able to download all the files from my blackberry. question, if i plug it to a wired connection will it be able to fix it self? it keeps on saying that there is an update available then it tries to connect.

Hi,

I think you will need a wired Internet connection (for your pc) to be able to solve the wireless issue.

I'm at my friends house using his wired, it downloaded all the updates and what not. Shouldn't it search for available networks?

Hi oscarm,

First reboot your pc.

Then please follow this procedure on your laptop, so we can analyze the current health of your wireless configuration in Ubuntu:

Step 1: Open Terminal from "Applications->Accessories->
Terminal"

Step 2: Run the following commands (type each then hit <enter>)

sudo iwlist scanning
nm-tool
iwconfig
ifconfig
sudo lshw -C network
lspci
lsusb
uname -a
dmesg|grep ound
dmesg|grep etect

Step 3: Post results (cut/paste terminal output from each command) here

Regards,

Mark

Hi,

Did you scan for wireless networks at your friend's house? Maybe your friend does not have a wireless network?

Did you also run the following command at your own home again?

sudo iwlist scanning

Mark
