Thanks Popper,
I have tried
http://www.routerlogin.net/basicsetting.htm as well. However, when I click
'apply' (without changing anything - i.e. Dynamic IP and auto DNS), the same problem happens, I lose the Internet and port lights on my modem.
I have not tried setting a fixed DNS though, I'll try this when I get home. Will let you know how I get on.
Thanks!!!
Any other suggestions would be welcomed as well.
