Hi,
again I have to tell you that your stable versions do not work with
Ubiquiti SR2 cards. A panic happens with the simplest setups. I have used
my Alix board as client with wpa2 RSN encryption. After maybe 10 minutes
of pinging the panic appears. Its the same thing as it was with 0.9.3.2
and 0.9.3.3. BUT: with the trunks between 30XX an 3279 the problem was
gone. So my question is: what bug has the stable release which the trunk
has not?...
My system: Alix boards (different types), kernel 2.6.24-mesh, voyage
linux, 2x ubiquiti SR2, wpa_supplicant versions 0.5.9/0.6.1/0.6.3 ...I
tested them all.
So do you madwifi-developer need some ubiquiti cards th fix this bugs in
the stable release? If it is so, please tell me.
