I have deployed 1200 access point with B radios and 350 PCM and PCI
cards. I
am using all of the security features; Radius based LEAP, tkip, mic, MAC
authentication, et al. I have two apps that work fine in a wired
situation
but when they move over to wireless they lock up the ip stack on the
machine. I based this on all other apps will loose network connectivity
and
pings start to die. Once the app is shut down everything starts working
again. The apps work fine over 256k frame-relay and DSl based VPN so i'm
sure it's not bandwidth related. I've watched the data stream over the
air
and on the switches with my sniffer and don't see anything beyond non
responding station and tcp disconnects from the servers. This even
happens
in the lab with only one machine so I know it's not congestion. I've
tested
the bandwidth capabilities with some hard core bandwidth hogs and they
work
fine, the problem is only with these two client-server apps.
Seems to me that this is a driver problem, anyone else see this.
Thank You in advance for any ideas.
