    Router slowing internet connection

    Hi.

    When I use the internet just through the usb modem the connection is fine. However, when I connect through my router (wired or wirelessly) the connection speed appears to be drastically reduced. I used this router for 6 months without any problems. I returned it and got a replacement but the problem still exists.

    I did a speed test I found in another thread on this site and here are the results. Any help would be greatly appreciated.

    WEB100 Enabled Statistics:
    Checking for Middleboxes . . . . . . . . . . . . . . . . . . Done
    checking for firewalls . . . . . . . . . . . . . . . . . . . Done
    running 10s outbound test (client-to-server [C2S]) . . . . . 558.0kb/s
    running 10s inbound test (server-to-client [S2C]) . . . . . . 239.29kb/s

    ------ Client System Details ------
    OS data: Name = Windows XP, Architecture = x86, Version = 5.1
    Java data: Vendor = Sun Microsystems Inc., Version = 1.6.0_14

    ------ Web100 Detailed Analysis ------
    Cable modem/DSL/T1 link found.
    Link set to Full Duplex mode
    Information: throughput is limited by other network traffic.
    Good network cable(s) found
    Normal duplex operation found.

    Web100 reports the Round trip time = 172.1 msec; the Packet size = 1360 Bytes; and
    There were 13 packets retransmitted, 43 duplicate acks received, and 48 SACK blocks received
    The connection was idle 0 seconds (0%) of the time
    S2C throughput test: Packet queuing detected: 24.74%
    This connection is sender limited 11.32% of the time.
    This connection is network limited 88.68% of the time.
    Excessive packet loss is impacting your performance, check the auto-negotiate function on your local PC and network switch

    Web100 reports TCP negotiated the optional Performance Settings to:
    RFC 2018 Selective Acknowledgment: ON
    RFC 896 Nagle Algorithm: ON
    RFC 3168 Explicit Congestion Notification: OFF
    RFC 1323 Time Stamping: OFF
    RFC 1323 Window Scaling: OFF

    Client is probably behind a firewall. [Connection to the ephemeral port failed]
    Information: Network Middlebox is modifying MSS variable
    Server IP addresses are preserved End-to-End
    Information: Network Address Translation (NAT) box is modifying the Client's IP address
    Server says [92.27.160.157] but Client says [192.168.1.101]
