Comment (by [EMAIL PROTECTED]):
Same problem here. I am running 1 AP and 1 client:
AP side: WRAP board AMD Geode, i586, only one piece of 5006x miniPCI.
madwifi-ng-r1411-20060124, vanilla kernel 2.6.15.1 (Gentoo kernels 2.6.14-
gentoo-r5, 2.6.15-gentoo-r1 tested too), gcc-3.3.6, uclibc-0.9.27-r1.
mode master essid pokus channel 36 rate auto ip 10.0.1.254, default gw
10.0.1.1
Client Side: Any PC, only one piece of 5006x miniPCI.
madwifi-ng-r1411-20060124, any kernel, any system.
mode managed essid pokus ip 10.0.1.1
On the client side i am sending a 16kBytes ping flood to the AP:
hping2 10.0.1.254 -1 -i u10 -d 16384
On the AP side i am sending a ping flood to the client
hping2 10.0.1.1 -1 -i u10
after some minutes ping stream stops and ATH cards are disassociated. In
the messages log appear: (system date is not set.....so dont look at the
date...)
