Trying [Hardy Alpha-3] (Live-cd session) Iwas able to make a wireless connection and it seems to be stable. Eventhough the ssid is not listed, using the 'connect to another wireless network' function helped me establishing a WEP encrypted connection. The LED is still not showing however.

Hello,
On Hardy Alpha 4, after boot, ipconfig shows eth0 (wired), eth1:00 and wlan0_renamed. The latter seems to have wireless capabilities but doesn't work (manually with iwconfig)
After playing around with ifconfig up/down and ip route the list changed :O to eth0, eth1 and wlan0_renamed. This time wlan0_renamed worked (the exact same iwconfig command)

I think something with udev naming scripts is wrong but I don't have the faintest idea.

Vlad (b100dian) wrote :

The actual steps to connect with iwconfig on Alpha4 are (to me): rmmod iwl3945 && modprobe iwl3945 && /etc/init.d/dhcdbd stop && iwconfig (your settings here) && dhclient
I am using only wep because of this

I'm confirming this on hardy AMD/EMT64 updated to this date.

Today I had this problem using WEP with a 802.11b router but haven't faced it
with WEP on my regular 802.11g one. NetworkManager asks for the keyring passwd
at session init and appears to associate correctly with the AP but the connection
doesn't work. I currently don't have much details but will follow up as soon as I collect
them (I have to get back to the same place tomorrow).

Briefly:

Card: Intel Corporation PRO/Wireless 3945ABG Network Connection (rev 02)
Module: Intel(R) PRO/Wireless 3945ABG/BG Network Connection driver for Linux, version: 1.2.0
kernel: 2.6.24-8-generic #1 SMP Thu Feb 14 20:13:27 UTC 2008 x86_64 GNU/Linux

This could be related; I'm seen a lot of messages like this one on syslog:

Feb 21 01:36:53 segfault-delly kernel: [ 354.019822] eth1: RX WEP frame with unknown keyidx 0 (A1=01:80:c2:00:00:00 A2=00:1a:70:58:dc:04 A3=00:1a:70:58:dc:04)

(happens even with the _working_ WEP/802.11g combo)

This sounds like related to https://bugs.launchpad.net/intellinuxwireless/+bug/190475
only that the problem here is not syslog getting filled with trash but the connection not
working at all :-).

Is there someone working on this? I'm of course willing to help getting this fixed.

[hardy alpha5 with all updates] CAN connect, NO led.

I had a hard time making it work, but succeeded. I had to configure my wireless router to broadcast SSID and use WPA instead of WPA2.

If you change SSID, Network Manager is slow to recognize it and still tries previous configurations for some time. Keyring access by NetworkManager (if you don't bother to make keyring accessible to NM) might also be part of the problem.

I have the same problem. I cannot connect.
This happens after upgrade to hardy development branch (beta with latest upgrade 26.03.2008).
Router broadcasts SSID, encrypts with WEP.

In my case it works too, but only in open networks. I.e. I have no troubles
connecting to my WLAN at home, but I can't connect to my university's WLAN,
which requires 802.1X authentication. Wpa_supplicant just can't attach to
the driver. Here is the output of wpa_supplicant trying to connect to my
university's WLAN:
dodo@2nd-of-12:~$ sudo wpa_supplicant -D wext -i wlan0 -c
/home/dodo/wpa_supplicant/FERwlan.conf

It used to work (with same config file) with ipw3945 on gutsy.

I have the same(?) problem. No LED and cannot detect the networks (Hardy fully updated, same result on Live CD). There is nothing under Wireless Networks in the network manager in the notification area.

I noticed that there is nothing in Restricted Drivers (now renamed to Hardware Drivers in Hardy Heron), while in Gutsy there used to be a proprietary driver for Intel Pro/Wireless.. something.

Running "lspci | grep Wireless" returns:

 Allthough PRO/Wireless 3945ABG does connect (manual connection). The last few days (after updates?) it keeps losing connection every 10 minutes or so (very annoying ). -> sudo /etc/init.d/networking restart gets the connection back up again but only to be lost in the next so many minutes again.
Also there is stil no led but I don't know if the one has to do with the other

Rammy's solution doesn't work for me.

My hardy installation uses the iwl3945 driver and can connect to an unsecured AP but cannot connect to my WEP AP with a hex key. It tries and then asks me to enter the key again.

If I boot into gutsy using the ipw3945 driver, it connects quickly and without any problems.

I'm still running Feisty because it's the only Ubuntu version that will connect to wireless networks - and even then it's not working as well as it should; when I try to log onto some networks it won't connect and I have to boot into Vista (always an embarrassment for an Ubuntu advocate like me). Annoyingly, Vista's wireless connection also seems to be quicker.

I tried 7.10 but no luck, and 8.04 also doesn't work. It's a shame because I'd really like to upgrade.

My laptop is a Toshiba A100 with 3945ABG wireless.

can the subscribers please confirm that this is still an issue for you?

also, be informed that the closed-source ipw3945 driver (which some of you used until gutsy) was replaced in newer linux kernels by the open-source iwl3945 driver, and ipw3945 was deprecated.

what is also strange is that i also have the 3945 chipset, and i've never had a problem, under gutsy, hardy or intrepid...

I'm having this problem too and I have the same network card. I just upgraded from 7.10 to 8.04 and now Network-Manager won't connect to my wireless router (with WPA2 encryption) anymore. It just tries forever. However, the network is shown to exist in Network-Manager.

If I issue the "sudo iwlist scan" command to scan for my network, it also acts strangely. The scan stops for a long while at eth1 (my wireless interface) and then most of the time it says "No scan results". Only at rare occasions, it shows my network although the router is very close to the computer and I know the signal strength is good.

What a pity this is. Wireless networking has worked fine for me in 6.10, 7.04 and 7.10 and now when I update to 8.04 LTS that I had intended to stay with for a few years, it doesn't work anymore.

No, I don't want to upgrade to 8.10. I get so stressed by upgrading once every half year and the errors it often introduces to upgrade so I have been longing for the day when I have upgraded to an LTS version. Therefore, now when I finally have got to an LTS version, I plan to stick with it for a couple of years. I expect that errors that exist in 8.04 should be fixed.

Christian, could you please try with an Intrepid livecd (or liveusb) and tell us if the issue is actually fixed for you in 8.10? The fix would in this case have to be backported to 8.04...
If not, you're having a different issue

Some more detailed information:

I have tested twice to disconnect the Ethernet cable after the computer has been started and both times the connection to the wireless router by Network Manager has worked although it has taken a long time (over 1 minute).

I have also tested twice to start up the computer without an Ethernet cable inserted and both times Network Manager has failed to connect to the wireless router (has given up after 2 minutes). I have tried a few more times to let Network Manager connect but that has also failed.

I attach a log from the case of starting the computer with no Ethernet cable inserted (an excerpt from /var/log/syslog/).

I will also attach a log for the case when the Ethernet cable is unplugged.

My router is set to use WPA2 with AES encryption and I had no problem to connect to it under Ubuntu 7.10.

 I'm using Ubuntu 8.04.1, Kernel version 2.6.24-22.
