I don't think NIC is disconnecting from the network or NIC is failing. But I can do check the OS and drivers problem. Because currently I am trying to ping from the window vista PC. Now I will try to ping from the Window 7 and than see the results.What do you mean by the wireless adapter reconnecting? Do mean that wireless adapter of PC reconnecting to AP?
yes that is what I mean. And you cannot figure out if this is happening or not. Don't rely on the wireless connection icon on windows.
It can be possible that your wireless adapters notices that the RF is busy and there were a few packet drops so it reconnects quickly. It's usually transparent to applications but if you are running a ping at that time ...
In any case, conclusion is : check your RF environment. How many APs around ? a lot of traffic ?
Thanks for your reply. I try to do ping with Window 7 PC. And it's are much better than window vista. But still sometime I got a higher amount of ping drop with a packet size of 2000 bytes. Please tell me is there any way to troubleshoot this problem. Steps to know the exact problem. It looks like that problem is due to the Window OS but I want to troubleshoot more.
Well, maybe Windows 7 does more retry or handles the wireless NIC better. But in any case, it might be an interference/environemnet busy problem. And for this you just have to troubleshoot your "air" :-)
So it can be anything.
Only a wireless sniffer trace will tell you what is happening exactly, but that requires special tools.
