Fedora 8 on laptop lenovo T61P

[Francois <frmas free fr>]

Hi,

I've been asked from the fedora mailing list, to post my problems here on 
that one.
This is it :
I have a brand new laptop Lenovo T61P, and i wanted to install Fedora8 on 
it.
The wireless stuff works fine, using another HD, with Windows Vista on it.
After different pbs, I got F8 installed on it.
Now when I boot, I have the following message :
"error for wireless request "set mode (8B06)". Set failed on device wlan0. 
invalid argument.

I have that message since I've updated the packages. When I just installed 
F8 from the DVD, I didn't get that warning, but the wifi didn't work 
though.
The little led that shows that wifi is activated is off.

The wireless I have is :
03:00.0 Network controller: Intel Corporation PRO/Wireless 4965 AG or AGN

After a while, I have my wireless stuff that works. But it works, only if I 
run knetworkmanager. If I stop it, it doesn't work. The led that shows that 
the wifi function is running doesn't work, but I don't care.

The pb I have is that knetworkmanager doesn't take care of the IP address I 
wrote in the ifcfg-wlan0 file. It takes an IP from my dhcp router, but my 
laptop has a fixed ip, It is configurated that way, it is not supposed to 
take an IP from my dhcp router.

Another pb, is that I'm disconnected from the network after 8 or 10 minutes. 
I have to stop my connection from the icon on my desktop and to connect 
again to the wireless network. Something is broken somewhere. I didn't have 
such problems before running my old laptop and F7.
