Lost wireless list

**antiphos1** · 02-11-2010

I am running Ubuntu on an HP laptop. Up until two days ago, it could access our Bell combined wireless modem/router. Now linex cannot find any wireless networks. I read of a similar problem and ran the following to help in analysis. Unfortunately I am not familiar with the internals of Linux.

lspci | grep -i net

Please post the output of

Code:

dmesg

It'll be long use code tags.

Also, does the following list available networks?

Code:

sudo ifconfig wlan1 up
sudo iwlist wlan1 scan

Thanks for the quick response. Here are the commands you requested. Terminal seemed to run out of space for all the list for dmesg,

I played around a bit in response to the replies from Ubuntu but to no avail. Below is what I got.

garry@garry-laptop:~$ /etc/init.d/networking stop && /etc/init.d/networking start * Deconfiguring network interfaces... ifdown: failed to open statefile /var/run/network/ifstate: Permission denied
Rather than invoking init scripts through /etc/init.d, use the service(

utility, e.g. service networking start

Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the start(

utility, e.g. start networking

I believe this bit is the core of the problem

Code:

[ 1841.428465] iwl3945 0000:02:00.0: MAC is in deep sleep!. CSR_GP_CNTRL = 0x000003C8

[ 1841.428465] iwl3945 0000:02:00.0: MAC is in deep sleep!. CSR_GP_CNTRL = 0x000003C8

I found a couple of bug reports regarding it from various times, but no real solution.

The only thing I can think to try is installing newer drivers. The easy way is

Code:

sudo apt-get install linux-backports-modules-hardy

Restart and see where you're at.

If that fails, you can get the absolute latest drivers by compiling compat-wireless.
Download - Linux Wireless

You'd need to make sure you have the build-essential meta-package installed first.

Code:

sudo apt-get install build-essential

I have tried a couple of things to no avail but it does look like it might be a bug. Not sure why it happened suddenly and had been working for a few months when it failed. Here is the output from lshw:

maybe you upgraded your kernel and you installed the drivers of the Wifi using the make/make install technique.

**antiphos1** · 02-14-2010

I did the upgrade to Koala but it continued working fine after that. My daughter was using the computer last week when it failed (lost the internet connection) and I don't know if it had done a recent update when she was using it and she did not know or remember either. Presumably something changed while she was online but she did not notice anything.

**kmitnick** · 02-15-2010

is it possible that the wireless switch is set to "Off"!!

and can you post the output of this command

lsmod
