We definately need more info as to how your network is set up to be able to give you any kind of an intelligent answer.Specifically is it DSL or cable and how exactly are you sharing it, specifically what is hooked to what and what hardware are you using. I can say that if you just have a true ethernet hub in place then that probably is the problem, and you need to upgrade to a true cable/dsl sharing router..

ok, lets break this down.

Since the internet works fine when only 1 PC is connected we can rule out the ISP/NSP.

1. Ok, moving forward, have your network setup, but only have 1 PC turned on and see what happens.

2. Try each PC that way.

3. What type of modem/router/hubs do you have?

If you are using a Hub in place of a switch that will slow down the connection because hubs only allow 1 device to communicate at a time. A switch allows all devices to communicate at the same time. With Hubs you have packet Collisions
, switches you don't.

Every time a packet has a Collision with another both packets have to be resent, causing delay.

My connection is ADSL 1000 and I am using netgear router with firewall...the router act as dhcp server and it assign ip address to all workstation in the network. All workstation get ip address from the router. I don't think there is collusion problem because I had my networking running fine few day ago. So if collusion occurs the network wouldn’t run. If I use just one computer, the speed is fine but when I use more computers the speed drops...
