DESCRIPTION="A simple WEP encrypted wireless connection"
INTERFACE="wlan0"

This set of configuration dosen't get connected to internet. The wirless indication light is on but not blinking.

I can manually bring it up by using

sudo netcfg hw

The other problem, which I guess is very common to linux users, is the wireless isn't waked up after resume from suspend. In my case, it can't be waked up even if I use the manual method. This is more important than to get it work on boot because I usually put my computer to sleep instead of power down when I am not using it.

I am trying Arch Linux on my old laptop, if it works well, I'll put it into my work desktop.

Yes, I upgraded immediately after the installation of Arch.

uname -r
2.6.32-ARCH

I am not really sure, but downgrading the kernel to 2.6.31 should work.
A lot of people have a similar problem, and for all downgrading the kernel worked.

Re: Mad: Can't get wireless work either on boot or after resume: 3945ABG

Let me describe the problem in more detail. After resume from suspend, the wireless light blinks for a few seconds and goes out. After that, even the manual method "netcfg homewireless" won't work. The error message says "DHCP IP lease attempt failed.".

The manual netcfg way is not working good even at boot. I run netcfg, the wireless light goes on but not blinks, I cancel the command while it's busy and run again, the wireless light blinks and it's done.

Maybe another network manager will work?

Re: Mad: Can't get wireless work either on boot or after resume: 3945ABG

Can you post the output of

dmesg|grep iwl

this might be the same bug as a lot of people are having and which should be resolved in linux 2.6.32.3, which is currently in testing.

I had this issue. I can confirm downgrading to 2.26.31 works. I can upload the package for you if you're using x86_64.

EDIT: Upgrading works  too.

I upgrade to the latest kernel, but still the same problem. Acutally there is a error message just before the login prompt appears. Where can I get all the messages when the system is booting?

Re: Mad: Can't get wireless work either on boot or after resume: 3945ABG

Curious if anyone has a resolution to this issue, as it just started happening to me since upgrading (since before xmas - busy). I too can't regain connection after waking up.

My temporary fix to this (which is very annoying) is..

rm /var/lib/dhcpcd/dhcpcd-eth1.lease
/usr/bin/netcfg-auto-wireless eth1

Obviously I don't want to have to do this every time my laptop wakes up, as this could be several times per day.

OP, have you figured out a solution?

Could anyone comment on this?

Re: Mad: Can't get wireless work either on boot or after resume: 3945ABG

Now I used wpa_suuplicant, and the problem is gone.
