go into control panel & network connections. highlight local area connection, right click & click on properties.
(new window opens) scroll through options & highlight tcp/ip if there are 2 highlight ipv4 not ipv6. next click properties & check that it is not set to manual ip, make sure both boxes stating automatic are ticked. it should then pick up the correct ip address with router connected. if it doesnt reboot modem only.
