iwl3945-module doesn't work with Intel 3945 WLAN :-( ?

Asked by dei on 2008-04-25

Running Edgy, Feisty, Gutsy the Network-Card of my HP Pavilion dv2000 ran perfectly. Today I tried the basic functions like Networking and Filesystems with the Hardy Live-CD (final). First Networking seemed fine, because nm-applet seemed to find and connect to my wireless-network but as I tried connecting/pinging to any host (for example my router) - no answer. Network-Manager got a DHCP-Ip-Address, the Gateway-Address and Subnet-Mask no problems, but seems to not really be connected to the access-point. (pinging localhost works, so basic networking shouldn't be the problem)

edit: found out it is the iwl3945 driver included in hardy-kernel which doesn't work with my hp pavilion (but pretends to work). Is there a way to compile the ipw3945 driver on the hardy-kernel? (a module?)

by the way, i have no encryption activated, so that isn't the problem...

dei (cephos) said : #3

I guess i got the reason for myself: hardy includes only the iwl 3945 (open, not working) driver instead of the ipw 3945 (proprietary, but working with gutsy and previous versions) but don't know how to fix it.. Have I really to downgrade my kernel to gutsy-generic to continue using ipw 3945?? :-((

Is there any other solution to get it working with 2.24 kernel (without recompiling the whole kernel)?

Jrojo (rojojoseph) said : #4

Hi ,

I do had the same problem.
My wifi was working fine Ubuntu 7.10 with restricted driver. In Hardy the restricted driver for Wireless card is not listed at all.

So using Package manager install ndisgtk.

after that you will find System - Administration - Windows Wireless Driver.

Download corresponding windows driver and install using this interface.

Once you restart the system wifi will start working. this will help you to install proprietary driver.

dei (cephos) said : #5

thx for the hint. That would be with ndiswrapper i guess. (not really my wish but surely a working solution) i'll try it if my current method prooves not enought stable.

my current solution: activate backports repo, install linux-backports-modules-hardy-generic then reboot, after reboot i made sure the iwl3945 and the iwlwifi_mac??? modules loaded, made a new file /etc/modprobe.d/iwl3945 with following content:
"
alias wlan0 iwl3945
options iwl3945 disable_hw_scan=1
"

run "depmod -ae" and restart again, then it should be working.. (I'm not really sure what was the command which really solved it but that are all methods I read about to fix "any" problem with iwl3945, and one of them, or the combination worked for me)

drw (david-r-white) said : #6

I've got the same problem on a Toshiba Tecra A6 laptop, with the Intel 3945ABG wireless interface.

Trying ndiswrapper didn't work, as the network I'm trying to connect to is WPA Enterprise and dmesg shows that this was not supported by ndiswrapper with Intel's driver.

dei, please could you provide more details on how you got this to work? I don't have internet access on the laptop, so I can't use the package managers provided.

dei (cephos) said : #7

Sadly the connection wasn't really stable and it didn't connect after some reboots. So I decided to install the windows-driver with ndiswrapper. No problems installing it, but as soon as I wanted to connect to a WPA-Network, NetworkManager --no-daemon spit out a whole bunch of errors and doesn't seem to get the network's shared-key:

And nothing more happens (and I can't see my Networks any more)

I tried to connect to another wlan in my reach (unsecured), it connects but is really unstable and NetworkManager spits out the following errors ever-repeating:
ioctl[SIOCGIWSCAN]: Resource temporarily unavailable
ioctl[SIOCGIWSCAN]: Resource temporarily unavailable
ioctl[SIOCGIWSCAN]: Resource temporarily unavailable

ioctl[SIOCGIWSCAN]: Resource temporarily unavailable
NetworkManager: <WARN> request_and_convert_scan_results(): card took too much time scanning. Get a better one.
ioctl[SIOCGIWSCAN]: Resource temporarily unavailable

(the same thing I already had with iwl3945 driver, and couldn't fix it some times)

any idea what could it be? Regarding the many new bugs connected with iwl and the new NetworkManager and my different error-messages I think I'm having more than one bug involved.

dei (cephos) said : #8

deactivating the wpa-encryption helped, but now my network is only limited to some mac-addresses (not really secure). I'm stil working with ndiswrapper.
Would be cool if someone could give me a tip how I can reinstall the ipw3945 module on the 24 kernel and the good old feisty-version networkmanager.

drw (david-r-white) said : #9

I gave up with ndiswrapper as it wouldn't work with my University's WPA Enterprise enterprise network, but after returning to the original driver and messing around I finally got it to work! It's been working consistently for a week now.

Unfortunately, it's difficult to work out exactly how I fixed it! However, if you want any details about how my system is configured I can provide them.

Cheers

Dave

Hello, I had / have similar problems. I tried wicd and NetworkManager. But in both cases the key point was if I had PERFECT wifi signal during connection initialization. If I took my laptop < 5 meters from the router, connection has been successful and I could leave this area and still worked perfectly. Currently I have NetworkManager + linux-backports-modules-2.6.24-16-generic

jlechner@NTB2007:~$ lsmod | grep iw
iwl3945 93940 0
iwlwifi_mac80211 219108 1 iwl3945

ifconfig, iwconfig same as described above

So currently, if I lost connection, I go near to the router, restart connection and next I go back ;-)

drw (david-r-white) said : #12

I added this file as part of my fix, but it didn't seem to work straight away. After messing with loading the modules it eventually did work.

dei (cephos) said : #13

The problems vanished for me somewhere between hardy and jaunty, so for me its solved.
