[network-admin] ipw2200/Intel 2915abg Wireless 128-bit WEP doesn't work, must set up manually

Thanks for your bug. What version of Ubuntu do you use? Is that issue specific to gnome-system-tools? Is the network correctly set on boot? What do you do to have it not correctly configured? Do you have anything useful to /var/log/messages or /var/log/syslog then?

I am using the latest 64-bit desktop version, just downloaded a few days
ago. My solution came from a search on the net and found that several
other people have had the same problem. The other network
configurations work fine, and the WiFi card is able to connect to an
unencrypted network using the gnome tools-- just not an encrypted one.
When attempting to connect to an encrypted wireless network, the
connection is made and the network status shows packets are being sent
with one or two initial packets being received, however the system is
unable to communicate due to the lack of the encryption key being set
correctly.

The Intel documentation for their driver is very specific in that the
encryption key is to be set at time of module load.

Initially, I used the Gnome tools set up the wireless information which
just included the ESSID and 128-bit encryption key and to get the IP
address from DHCP. I haven't messed around with Ubuntu enough to know
how it's configuration works internally.

I am experiencing the same problem. I am running ubuntu 6.10. The wireless network connection does not work on boot with an encrypted router. I have tried both WEP and WPA. The only way I can get the wireless card to connect is to disable encryption security on my router. I am using a NETGEAR WGR614 v3 router with the latest drivers (V2.16RC4_1.0.2). I have not attempted the suggested fix - I am not sure which configuration file to modify to change the order of iwconfig commands.

I had a similar problem with WEP not working. I found a work around by switching my router to use WEP (Shared) instead of WEP (Open). I'm using Ubuntu 6.06.

Thanks for the reply.

I got WEP working with the suggested fix. I moved the iwconfig commands as
suggested in the wireless-tools file under /etc/network/if-pre-up.ddirectory.

Has anyone got WPA to work under Ubuntu with the 2915abg wireless card?

That's not clear from previous comments if the bug is happening only with network-admin

does it do the same if you do an ifup by hand for that card?

I don't claim to have the detailed answer to this bug, but I can tell you who (what) does...the package wifi-radar. I saw this failure on 3 out of 3 laptops (running a prism2, a Cisco 350 PCMCIA, and Intel Pro/wl 2100). In each case, configuration via wifi-radar solved the problem. Hopefully, this will provide a workaround for users and a pointer for the developers as to where the problem might be.

I'm using Feisty Beta and I'm experiencing the same problem.
My computer is a Toshiba Satelite SM30-801 and I have had no problems with my wireless card (eth1) since I upgraded to 5.10 version. Last saturday I upgraded from Edgy using the "update-manager -d" command and now I need to manually reconfigure my wireless connection every time I restart my laptop.
I use the " iwconfig eth1 essid "My_ESSID" key "My_128_WEP_key", and after that I need to type "ifdown eth1" and then "ifup eth1" to make it work.
Any helping comment?

Just wanted to point out that I experienced a similar problem with "Limited or no connectivity" that was caused by not being able to renew my computer IP address dynamically. Having used all the default options, I was desparate so resorted to experimentation to isolate the problem. I found that when using WEP, my netgear wireless adapter would only work with 64 bit encryption. This was originally set to 128 bit. This is ALL I changed and since then everything has been working fine. I suspect this is probably a windows bug but noticed that others have experienced similar problems with other wireless card firmware. Consequently I am unsure still where the real problem lies. If anyone finds out, I would be interested to know. Thanks.

Do we have any info from Gutsy or Hardy on this?

I use ubuntu 7.10 with a 2915abg card on a Dell latitude. Wireless works most of the time except when many neighbours use their routers as well. (Most of my neighbours use their wifi infrequently only.)

So when there are more than, say, 3 or 4 other routers sending I get a very flaky connection. It drops often and sometimes doesn't reconnect. I'm on channel 1 and the others are on channels 6 and 11. So interference doesn't seem to be a problem.

Usually it helps when I switch from roaming mode to manual configuration, but not always. I haven't tried the step-by-step iwconfig approach above yet. So far, in some cases I had to reboot into windows, connect there (this works always), reboot linux and manually config the card through the nm-applet. This is unfortunately no joke.

Oh, I use a DI-524 configured with WEP2-PSK(AES).

I'm using Ndiswrapper 1.53 to work with my broadcom chip, it seems the problem is a bug that snuck into network-manager after 6.10.

I can connect fine using iwconfig, but wifi radar and network-manager seem unable to correctly configure my wireless.

Suggested solution was to install a previous version of the network manager (aka the ubuntu 6.10 one) network-manager_0.6.3-2ubuntu6_i386.deb which doesn't appear to have the bug.
