    I never had disconnection before for about 2 years.
    but recently when i reinstall WinXP PRO SP2, everything changed.
    I started to get random disconnects every 6.10.15 minutes.

    I'm using WRT54G v2 with WMP55AG and a wired client(never had problem, either before nor now).

    PROBLEM
    "Signal Strength : Excellent, but no internet, can't ping router either, had to REPAIR, reconnect, REBOOT, etc."

    CAUSES
    -Inteference? I tried all channels, same thing. so, not. (no phone, no microwave or electronic might cause)
    -High traffic? Maybe (BT), but as i said, i never had problem with wireless before.

    3 days of research and disconnects... most of solution of the forum didn't help much, still get disc randomly. somehow, i played alot with the Advanced Setting, and solved the problem, so i think you guys mighy give a try if you are in same basket.

    1- Wireless Adapter: turn off windwos's firewall.

    2- Don't use the newest adapter driver! use the driver on CD whitch came with your adapter. Also, I'm using Windows's wireless control program, not linksys's. after backward your driver, Go to your adapter's property, set its transmit power to LOWEST. everything else untouched.

    3- get the TCPIP connect limit remover from (Event id: 4226)
    Download Here
    (Windows has a limit for TCPIP connections, e.g. you often get disc because of BT,eMule, etc.)

    PS: you don't have to install this if event id:4226 isn't a issue for you
    (for check if you get the event warning, go to RUN- "Eventvwr.msc"-
    System
    )

    4- REBOOT you windows, get on your router

    5- flash your router's fw to HyperWRT 2.1b1

    6- do a HARD RESET (press reset button on the router for 30sec)

    7- do a SOFT RESET (Administration - Factory Defaults)



    ** EVERY SETTINGS NOT MENTIONNED BELOW = DEFAULT VALUE **
    (setup your internet connection in SETUP-BASIC SETUP first)

    8- Wireless tab - Basic setting - Channel 1, Mode G-ONLY( since i don't have B clients). SAVE

    9- Wireless tab - Advanced Settings - Frame Burst:Enable (enable this only if you have only 1~2 Wireless Clients), RTS Threshold:2304, Transmit Power: 25%. SAVE

    10- Applications & Gaming tab - Port Range Forward - type in ports you need for your BT, eMule, games, etc. to your DHCPed IP adress, you can know it by go to START-RUN-CMD-IPCONFIG. SAVE

    11- Administration tab - Management -START UP-
    *copy past following scripts into it*

    echo 4096 > /proc/sys/net/ipv4/ip_conntrack_max
    echo 1 > /proc/sys/net/ipv4/icmp_echo_ignore_broadcasts
    echo 1 > /proc/sys/net/ipv4/icmp_ignore_bogus_error_responses
    echo 512 > /proc/sys/net/ipv4/neigh/default/gc_thresh1
    echo 2048 > /proc/sys/net/ipv4/neigh/default/gc_thresh2
    echo 4096 > /proc/sys/net/ipv4/neigh/default/gc_thresh3
    echo "600 1800 120 60 120 120 10 60 30 120" > /proc/sys/net/ipv4/ip_conntrack_tcp_timeouts

    SAVE, REBOOT ROUTER (a button at the button)

    ---------------------------------------------------------------------

    This is it, i didn't get any drop off since 13 hours (and keep counting)
    with BT, FTP on.

    I hope it might help you guys because i know how frustrate the disconnect is while you playing your games online and all...

    I'll keep you guys updated with my online status.
    Good luck.
