    I have 2 routers set up, my internet randomly randomly loses/regains connection.

    First router is connected to modem, that's an Actiontec router that's wireless. Second router is a D-link DI 624 wireless router. All the computers are connected "Wired", only wireless devices are the laptop(which is connected wireless to Router 1), and Wii(which is connected wireless to Router 2). Router 2 is a brand new router btw, and I upgraded the firmware on it.

    So here's how my connection is setup: Internet > Modem > Router 1 > Router 2 > This computer. If I simply directly connect this computer to Router 1(instead of connecting it to Router 2), the disconnections doesn't happen.

    Now at first I had only one router. I installed a second router by simply shutting off comp, plugging a network cable from router 1 to router 2, then simply plugging an additional cable from router 2 to my computer.

    I am not sure if I set up 2 routers correctly but all I know is that it works fine "sometimes", the wireless connection(from the second router) always seems to work but the wired connection from Router 2 to this comp.


    The intervals varies, some days it may be 3 minutes between each disconnection and reconnection(which isn't too annoying), some days it may be 15 seconds(extremely annoying). Sometimes the disconnections do not happen at all.

    Here's what I've tried:
    1. I've tried rebooting the router, doesn't fix problem.
    2. Restarting computer doesn't fix problem either.
    3. I tried the "windows repair network" thing on "Network connections", do anything.
    4. Tried disable and renable network.


    What I know is that the problem could be one of the following:
    1. Router 2 could be defective, though the wireless connection on Router 2 works fine.
    2. The ethernet cable between Router 2 and my computer could also be defective? Do faulty ethernet/network cables randomly "lose and regain" connection. The ethernet cable is new and is only 10 feet long, it's CAT5. Unfortunately I don't have a spare ethernet cable, but if anyone knows if Ethernet cable could be the problem?
    3. Maybe wrong setup/settings? Are there any settings that may fix the "lose connection and then regain connection" problem?

    Some things you can try here.

    1. Change the channel on the router, I like channels 1, 6, and 11 in the US.
    2. Update the firmware to the latest version available on the manufacturer's site.
    3. Reset the router to factory defaults and reconfigure.

    Many times these measures will resolve a lot of intermittent issues.



    For multiple routers, I also suggest this configuration.

    Connecting two (or more) SOHO broadband routers together.

    Note: The "primary" router can be an actual router, a software gateway like Microsoft Internet Connection Sharing, or a server connection that has the capability to supply more than one IP address using DHCP server capability. No changes are made to the primary "router" configuration.

    Configure the IP address of the secondary router(s) to be in the same subnet as the primary router, but out of the range of the DHCP server in the primary router. For instance DHCP server addresses 192.168.0.2 through 192.168.0.100, I'd assign the secondary router 192.168.0.254 as it's IP address, 192.168.0.253 for another router, etc.

    Note: Do this first, as you will have to reboot the computer to connect to the router again for the remaining changes.

    Disable the DHCP server in the secondary router.

    Setup the wireless section just the way you would if it was the primary router, channels, encryption, etc.

    Connect from the primary router's LAN port to one of the LAN ports on the secondary router. If there is no uplink port and neither of the routers have auto-sensing ports, use a cross-over cable. Leave the WAN port unconnected!

    This procedure bypasses the routing function (NAT layer) and configures the router as a switch (or wireless access point for wireless routers).
