I am trying to set an very simple experiment for VoIP purposes. The system set up is the following. One computer (User1) is on a Ethenert network connected through a Full duplex to an Wifi (802.11b) Access Point(AP). In the wifi AP there is only one computer (User2) whose aim is to send RTP packets to User1 and listen to those that are coming back. From User1 prespective, it will receive packets from User2 and send them back to User2, as a proxy style.
Now, I have wireshark running in both machines, User1 and User2, plus i check the sequence number of RTP packet to make sure that i know when a packet is received. Surprisingly for a packet flow of 706 packets, User2 rarely gets more than 650 packets back. Since Wireshark of User 1 shows that all 706 packets were sent back I can guess that packet were lost at the AP buffer.
Question is, is it not too many packets lost for a single RTP streaming transmission? I could expect to loose some of the packet but not a 8% or so.
The wireless router that i am using is a Dlink G604.
