We run 4 computers (1xLaptop & 3xDesktops) on a wired network using 2 D-Link Routers. We also have an Bigpond ADSL connection connect to one of the routers via the Modem (2Wire) given to us by Bigpond. All computers are can access the internet but it randomly drops out. By randomly, I mean it may happen 2 times a day or 10 times a day. When it drops out the lights on the Bigpond modem do not change and stay lit. Bigpond says that there is nothing they can do. I have tried to connect the modem (via usb) to one computer and it doesn't seem to drop out as much but still does. If you unplug it and then plug it back in, the internet comes back straight away. I have no idea what is causing the problem. We have Norton Internet Security 2008 on all computers if this helps. caso1992

Try this, upgrade firm ware on your router and call your ISP for a newer modem if it doens't work.

Both routers have the latest firm ware. I will call Bigpond today and ask but I don't think they will do anything because all the lights are still flashing when it drops out. But thanks anyway. caso1992

So basically, you have a total of 4 devices but you're hooking all these up to a 2 routers? Why don't you just use one router? You should have 4 wired ports on each router which is enough for your 4 devices. It sounds like there's confliciting default gateway addresses using two of them together. If your routers have less than 4 ports each, you can get a switch to connect to one router or you can turn the second router into a switch. You would need to disable DHCP not utilize the WAN port on the second router.

The reason there is 2 routers is because there are 2 computers in a back office and 2 at the front desk. There is only one LAN cable running from the back to the front. The front router doesn't have anything in the WAN port and is setup to direct the internet traffic to the back router with the modem plugged into the WAN port. Both the front and back computers have the internet dropping out. Both the routers are D-LINK DIR-120. caso1992

Under WAN on the router the following is displayed: MAC Address: ####-####-####-#### (address is actually displayed) Connection: DHCP client Connected IP Address: 10.0.0.5 Subnet Mask: 255.255.255.0 Default Gateway: 10.0.0.138 DNS: 10.0.0.138 When the internet drops out the DHCP client becomes disconnected, even though the modem lights are still on. caso1992

Called Bigpond, and getting a replacement modem sent, still waiting though. caso1992
