Cannot access internet with Belkin wireless router - please help

Hi I have a Belkin wireless G F5D7230-4, purchased in New Zealand.
It installed no problem.
When I first switch on the pc there is no internet connection, if I pull the power out the belkin and put it back in the internet starts working - I have to do this every time I switch on the pc.
When I search for wireless networks on my laptop it finds the belkin wireless and connects at 100% signal strength, but I cannot get the internet to work via wireless on the laptop - even if I reboot the belkin.
I can only access the http://192.168.2.1 when I first switch the pc on (ie when there is no internet connection). As soon as I pull power out belkin and put it back in I cannot access http://192.168.2.1 even though the internet is then working!

Please help, this is driving me nuts

I have adsl broadband via adsl modem which connects to the belkin, then belkin connects to the pc.

Hi there

Sounds like it could be a Gateway or DNS issue, is there anywhere you can enter the gateway and DNS addresses in the Belkin?
Other thing to check is the ADSL modem and the Belkin are not on the same subnet ie. the ADSL modem should not be 192.168.2.X. This is because the Belkin is a router and won't route to addresses in the same subnet.

Good luck
Dale
