[Winpcap-users] Ping works only when ethereal is ON

  We are working on  USB based WinXP network WLAN station driver.
We are facing an issue with the ICMP(the association to the AP is done).
We do a ping request to the AP and also get the reply from the AP.We 
also indicate the received reply to the TCP/IP stack but the successive 
pings do not take place.
The same happens when the ethereal(packet sniffer ) is on.
When we close the sniffer the successive pings do not happen.
We could not find any relation between indication of the received packet 
to the TCP/IP stack and the ethereal.
The firewall in the case of WINDOWS is TURNED OFF.
Can anyone comment on this.

Thanks in Advance
