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
