I have a Virginmedia modem and a Belkin 54g Wireless Router. One PC is connected via ethernet to the wireless router. The other two are laptops and are connected via wireless. If I switch the router and modem off, and all PCs off, then switch the router and modem back on, it's the first of the computers that I switch on that will successfully get an internet connection.

The one that succeeds though, gets an IP address of 81.109.xxx.yyy which in itself is somewhat odd. I would expect the PC to get an IP address of 192.168.2.xxx as that's what the router is setup to use for DHCP. The first PC fails to even ping 192.168.2.1, but it is available to ping 192.168.100.1 which is the modem.

The ones that FAIL to get an internet access, get an IP address of 192.168.2.xxx but get no DNS servers, can't ping 192.168.100.1 and can't ping any IP address out in internet land.

So it's as if the router acts as an access-point for the first PC that talks to it after a reboot, but then acts as a (bad) router for subsequent PCs.

Modem = virginmedia ntl:250 (255)
Router = Belkin 54g 4000uk
