wireless woes (2.6.10-1.766_FC3smp)

Hi folks,

I have a weird problem occuring since my last yum update of a fc3 smp
box (2.6.10-1.766_FC3smp) using ndiswrapper v1.1 2005-03-04 with a pci
dlink g520+ card (dwl-g520 f/w ver 2.04). Everything worked fine before
my brilliant plan of yum updating everything for my fc3.

I should note, I have cvs updated/recompiled/reinstalled ndiswrapper
since the update. Also wireless network is an ad-hoc.

I am a linux amature and not sure where to go to diagnose further. I
will first post the problem and then the diagnostics I have done thus
far. Would appreciate any assistance anyone could provide.

What happens is when I connect to the ad-hoc wireless network with my
windoze laptop, the connection is establised fine (whether or not i
encrypt problem is the same), but when i try to ping from laptop to
linux I get 4 x "request timed out".

Diagnostics
=========
linux box has 3 interfaces (eth0, eth1, wlan0) with wlan0 = 192.168.1.1

laptop wireless if = 192.168.1.2

on linux tethereal -i wlan0 i see occasional wins type broadcasts from
laptop indicating some sort of valid connectivity

still running tethereal -i wlan0 on linux whilst pinging from laptop i
see incoming arp requests broadcast to 192.168.1.255 "whohas
192.168.1.1 ??" but linux does not respond to the arp

small correction to above info. when pinging from windoze laptop
(192.168.1.2) to linux box (192.168.1.1) I get "destination host
unreachable" - not "timed out" as noted above.

Thanks in advance

Anyone have any GOOD references to how network flows should work for a
new device attaching to an ip network? At least that will help me know
what i should expect.

Thanks
