Thanks very much for the quick reply, i will give it a go, although i think i pretty much did that when originally installing it.
The router is a Linksys EtherFastÂÂÂà ‚® Cable/DSL Router with 4-Port Switch (
http://www.linksys.com/international...oid=6&ipid=367 ), modem a ntl home 200, and all pcs are running xp.
There is one pc connected to the router, and 2 others connected to a hub which then connects to router. In the previous setup the connections going into the router went into a switch instead, which had another computer connected to share the net. There are no firewalls at the moment, apart from when xp sp2 decides to start its built in firewall!!
As i say i am just unsure what could cause it as things worked fine for over a day. But i have suddenly had an idea. When setting up as things didnt work kind of on auto, i ended up enter info into the router like the ip. Now i wonder as the ips arent garenteed to be static, maybe it's changed and doesnt match the ip ntl is giving me. Is that a reasonable idea?
Also, to make things worse, im not even home and i have to describe and talk my girlfriend through all of this... Nightmare!
Thanks again.
