    If I face this kind of error, I'll capture the traffic with the WireShark on the source PC and the destination PC.

    I am already doing this,I can see all the traffic and data is getting exchanged between both though I am not able to ping.

    so the destination PC received and replied ICMP packets? did you take a look at the contents of the ICMP packets? How frequently did you send ICMP ping reset?

    I am continuously sending ping requests from both the side from the PC & from the board, but out of 20-30 requests I am getting response for 2-3 requests in about 2 -3 seconds delay. For rest cases I am getting host unreachable on board side & request timed out on the pc side..!!!
