Networking problem.

post #1 of 2
Thread Starter 
Sorry if I'm posting this in the wrong place but I'm hoping that someone on nbf can give some helpful tips. The computers I'm using for my network are desktop replacements though.

Anyways I've been having this problem for weeks and it's driving me crazy. I finally stumbled across this excellent website but still couldn't find an answer to my problem, although I feel that it is a common problem.

The issue I'm having is I'm using a Netgear FS605 v2 (fast ethernet switch) and connecting the cable modem to it via wires and also connecting two other computeres to the switch. However, it seems that only one computer may connect to the internet and it depends on which comoputer is turned on first (the computer that is turned on first can connect, however the second computer cannot). Anyone know where to start?

Thanks in advance.

Well, for one thing, a switch is NOT a router. So, just because you put a switch between two computers, doesn't mean that both of them can get on the internet at the same time. Take a look at the picture on http://www.netgear.com/Products/Swit...hes/FS605.aspx. You will see that the crossed port is connecting to a router.

I don't know how much you know about networking. Basically, a switch is just a fast way to connect 2 or more computers. A router is a piece of hardware that will do something called NAT (Network Address Translation). Basically, your internet provider is giving you 1 IP address. Without a router, the first computer turned on will get that IP address (from your cable/dsl modem). The second computer asks for a IP address also. However, since your one and only address is gone, it doesn't get anything.

A router will take that 1 IP address and put it on the external interface. Then, it will assign its own internal addresses to your computers. So, when your computer tries to load a web page, the router will translate your request into something suitable to be sent over the internet. When the web server on the other end replies, the router will translate that reply and forward it to the correct computer.

In short, buy a router and connect the dsl/cable modem to the router to the switch. NOTE: most routers can be connected to more than one computer, so you probably won't need the switch.
