    Since I upgraded to 5meg service I seem to be having a problem with wired and wireless slowdown. My equipment is as follows:
    modem: sb5100 motorola surfboard
    router #1: linksys RTP 300, 1.00.62 firmware
    router#2: linksys WRT54GS, 1.50.6 firmware
    I have had charter reprovision router and have tried numerous settings on both routers to no avail. I leave the LAN port on the rtp300 and go to the wan port on the wrt54gs. Only my wireless laptop is on the wrt, my other computers are on the rtp300. All computers have trouble going from page to page and I have to refresh numerous times to get a page to come up on any computer. Help me please!!!!!

    Curious why the desire to double NAT. I'd expect PC's behind the wrt to run slower because they're going through NAT twice. Granted most applications don't mind much..but some do.

    Are both routers on different subnets? You can't have them both on of them needs to be or, etc.

    Although...I'd rather run just one router....use the wrt in AP mode.

    guess I wasn't to clear;
    1. modem,
    2. rtp with 2 computers, then
    3. wrt simply for wireless

    As YeOldeStonecat mentioned, it seems you are employing double NAT. If not NAT, you are routing thru the WRT, and therefore should have at least 2 different subnets. I therefore think that your routing and subnetting is not set up correctly.

    Best IMO would be to eliminate the routing thru the WRT, and have all your devices and clients on the same subnet:
    1) Connect the WRT via a LAN port to the RTP's LAN port.
    2) Turn off the DHCP server on the WRT (assuming either your modem or RTP - but not both - supplies DHCP)
    3) Make sure the WRT has a unique IP address - not used by any other device.

    FYI: WAN == With Another subNet, so if you connect anything to a WAN port, the WAN side should be on a different subnet from the LAN.

    I easily understood your setup the first time I read it....I still maintain I don't like double NAT, even when setup correctly. I'd run your wrt in AP mode, as I mentioned above, and as Hennie also began to describe.
