I no longer use ubuntu 8.10. I'm currently running ubuntu 11.04, and
haven't seen this issue for a long time. It may even have been fixed in
a previous release (ubuntu 9.x or 10.x).

Hi Giancarlo, I'm running Ubuntu 11.10 on Vaio FZ21E. The module is the
same (IWL3945) and also the WiFi Card (Intel PRO/Wireless 3945ABG).
Looking in Synaptic I' cant find 'linux-backports-modules-compat-

that the compat-wireless is for linux image 2.6.32-27, and installing

iwl3945 is the

I'm having an interesting pattern here. On the 2nd resume after each reboot,
wifi doesn't come up. I get:
iwl3945 :0c:00.0: MAC is in deep sleep!. CSR_GP_CNTRL=0x
etc.
This is on a Lucid system, tested both i386/x86_64, all current updates.

Sorry for the false alarm :-( My solution isn't a solution. It just
makes resume more often to work. After 8-10 times I get:

I can confirm that this still happens on 10.04 - in fact now wifi dies
after suspend almost 100% of the time, while on 9.10 with the new
kernels it was doing it only about 1 in 4 times.

No, with the new kernel tonight the wifi was restored 3 times after
sleep, but this morning it didn't return. It seems that this happens
when the laptop has been sleeping for some time.
(But this kernel boots pretty fast.)

Unfortunately I no longer use suspend to ram, because once I spilled
some water on my laptop, and since an hardware problem makes it resume
itself randomly :(
So I can't confirm if I still encounter this bug or not.

Hi again,
I can say that with the kernel upgrade the problem is not totally fixed
here. It went to 100% of times with no wifi after suspend to maybe
20-30%, but the problem is still there.

Hi -
I'm running current Karmic 9.10 beta (2.6.31-14-generic), and am experiencing
this problem. What's odd is that I had thought this issue had gone away in
Jaunty, but upon doing a fresh install of karmic beta, it's back. It seems I
have a 50/50 chance of having the iwl3945 come back upon
Care to test and confirm this remains with the latest Karmic 9.10
release? ISO CD images can be found at

using a LiveCD. Thanks.

I am using vanilla kernel 2.6.28, no problem. But if I use 2.6.29 (and
2.6.29.2), built with old config, the problem occurs as described above.
What confuses me, is that other users with 2.6.28 have the bug, too. I
think, that there is some incompatible setting. If you need diffs, send

I am experiencing a very similar, if not the same, problem. I'm running

the wlan0 device does not exist. The problem persists after removing and

Hi Guys,
Care to test a few things . . . Can you first try installing linux-
backports-modules-intrepid to see if it helps. It contains an updated
compat-wireless stack. If that doesn't seem to help, care to test and
confirm if this issue remains with the most recent pre-release of Jaunty
9.04
I am getting exactly the same in Intrepid as well.
It used to be more random, now it's more like 9/10 times I resume, the wireless
doesn't work until I reboot.
