Where's the internet?? Problems with broadband connection in XP network.

I have a network of 6 Windows XP Pro computers sharing a DSL connection through a router uplinked to a switch.

The problem i am having is that the computers can access the router and it's configuration page but are not getting the internet. The router tells me that it is connected.

This problem was previously only on one computer while all others could access the connection but now all systems are affected.

Thanks in advance.

fakeemail,

Is your DSL connection using a dynamic IP address or do you have a static IP address from your ISP?  If you have a static IP, you may have the wrong DNS address inputed into the router which would explain why the router says it is connected, but the XP machines cannot access anything on the internet.  That happened to me one time and I was tearing my hair out and all I needed to do was check my config work.

If your ISP is issuing you an IP address all of the DNS settings typically come with it and the problem may be harder to trace.  Connecting one machine directly to the router and making sure all of it's network settings are set to default, taking all settings from the DHCP server (the router).

Hi fakeemail,

I assume all your connection was working with all 6 computers.
It happend to lose connection for only one but now it happends to all computer that cannot go on to internet, and you router access page tells you that you are connected.
1) try disconnect and reconnect in router setup page see if you still get a connection status.
If not you should try to shutdown modem and wait 1 min and connect it back again than retry   your router connection.
2) Check I mean really check if all XP if they have upto date patches and virus free.
Check to see if a specific port is running busy on router or your switch which ever connected to these computers.  If you found the busy connection, try unplug it and see if others can get on to the internet.  If this is the case you have problem with that computer, it might have NIC problem or it has been hacked or simply virus attack.

Hope these pointer would help,

It's sounds like a configuration problem, I would first make sure that the nodes are able to access the internet directly connected (1)to the dsl modem (2)through the router and (3) through the switch.    Good Luck!
