Since I got Verizon FIOS, I've been testing my BW using http://whisper.cs.utk.edu:7123 When I am wired connected through my WRT54GC I get really good BW, about 12.5 to 13 Mbps. However, when I come into the WAP side of the 54GC I get congestion and re-transmits and much less BW (see the 10s inbound test below, only about 5.5 Mbps) TCP/Web100 bandwidth test v4.12 click START to begin running 10s outbound test... 1845 Kbs outbound running 10s inbound test... 5761 Kbs inbound Web100 Inbound Summary: Packets to your host: 5772 of size 1260 bytes average RTT: 40.0 ms minimum RTT: 30.0 ms Maximum Expected Bandwidth: 17 Mbs Inbound limits: congestion 85% server: 0% your host: 14% Bummer! packets retransmitted: 11 congestion events: 4 Your host's receive buffer: 65520 bytes Server's send buffer: 82574100 bytes receive buffer: 65535 bytes Buffer sizes are very important in determining network performance. Larger buffer sizes can help increase thruput. If your buffer is smaller than the remote host, you should investigate increasing your socket buffer sizes. Web100 reports Tweakable Settings as: RFC 2018 Selective Acknowledgment: ON RFC 1323 Time Stamping: OFF RFC 1323 Window Scaling: OFF click START to re-test Any ideas why I'm losing BW on the WAP side?
