I recently had a bad time with my CEO's laptop(Its on M$ XP.As of now I can't even dream about having it on linux.But at least I am happy he admires Mozilla Thunderbird after using it).
It was showing a strange behaviour. The wireless network gets connected for a few seconds and then it immediately gets off from the network. When I try reconnecting it, it again repeats this same behaviour.I start a ping and the first few packets , say 12 or 15 of them give a response even if I try www.google.com if its done immediately after a reconnect to the wireless network , but then after a few seconds it even stops pinging to the gateway ( the wireless AP). I couldn't think of any firewall that would block any pattern of traffic only after a few seconds .
Well, finally it turned out to be an issue with the anti virus software installed , or rather a virus in the machine. The explanation I can think of is like this.
There's a virus in the system which the anti-virus seems to detect only after the network comes up and there's some regular interval when the anti virus software polls something to detect it and the moment it identifies the virus , it's inbuilt firewall cuts off the machine from the network.
If anyone has any better ideas , please suggest.
