I have an existing connection through my old laptop to a 3COM wireless ADSL router and can connect to the internet on my old laptop.
I tried a friends new Sony Vaio laptop and can connect to the router and see the router settings but can not access the internet.
I have checked the DHCP settings on the router and tried turning the firewall off but still no success. I can't see any problem with any of the settings on the router and as I have said the other laptop can still access the internet.
I have checks the ipconfig and the laptop does get the default gateway and leases an address from the router but can still not connect to the internet or ping any external ip addresses.
When I connected to the router using an ethernet cable I could connect to the internet. I am tearing my hair out - have asked many IT/ Network people but no one can see where the problem could be.
Any help is greatly appreciated!!
