Binary package hint: linux-restricted-modules-generic

Hello,

I have big problems with the ipw3945 ABG Network driver in Gusty-
Tribe-5. Doesn't work in Feisty too. I want to connect to an Vigor 2500
WLAN-Router.
(http://www.draytek.com/product/adsl_router_modem/vigor2500/vigor2500.php).
The Wireless Access Point is for "802.11b/802.11b+".

I can see aviable Wireless networks and their signal quality but I got
no connection to this Wireless Network using network-manager-applet.
Connecting to my wireless network works when i use manual configration
without roaming-mode of network-manager and static IPs. Then, network
connection ist really very very slow, not usable. (maybe similar to this
bug: https://bugs.launchpad.net/ipw3945/+bug/103210).

I tried do disable WEP encryption. Connecting without encryption didn't
work too.

My Hardware is a new DELL Inspiron 6400 with Intel Pro/Wireless 3945 ABG
Network card. That's one of those DELL Notebooks shipped with ubuntu
Feisty preinstalled in Germany. Also known as DELL Inspiron E1505n in US
I think.

But connecting (and speed) to this Vigor2500-802.11b-Network with
another Notebook (Samsung X20) with Intel Pro/Wireless 2200BG Network
card is no problem.

Wired Ethernet is working great with Vigor2500.

Connection and Speed in Windows Vista is working great with
Vigor2500-802.11b-WLAN.

Here are some Informations. If you need more, please let me know.
