Alright I am having trouble setting up my network. When I plug my computer directly into the modem I get a good connection. And when I use my router which is a DLINK DL-524. I also get a connection, but once I plug in another computer into the router all I get on it is a little or no connection signal on the computer. I have tried changing IPs and such. Do I just not have a port open or something?
Try checking the cable used (make sure its those straight ones and not the crossover ones) and if the router is set to be the DHCP server (most likely will be) - make sure that each computer that is connected is assigned the IP automatically.
