[jamier1985uk]

Hi ive got a new laptop (ACER 2423) running Windows XP and when i connect to my netgear wireless router, it connect successfully although the internet doesn't work. It says connected with signal stregth exellent, (it doesn't say limited or no connectivity). Also my friends laptop work perfectly with the router with the internet working fine, so im guessing its something to do with my laptop or settings. Any idea's would be greatly appriciated!! Thank you

Was your friend connecting to this SAME router on your network?
What kinds of configurations have been set up in the router? DHCP? Wireless security? MAC Address filtering?

What is the IP address that your computer is getting (or that you have statically set)?
Can you verify that the router's WAN interface is getting a public IP address from the ISP? (should be viewable in the router config page).
Try to ping both the router's LAN interface (usually a 192.168.x.x number), and the WAN interface (public IP address).
Next, try to ping google.com.
If that doesn't work, try pinging 72.14.207.99, and give us the results.

To ping, you need to open a command prompt.. START > RUN > type 'CMD' hit enter > command prompt now open...
Then just type ping[space][destination]
Ex: ping google.com
