Perplexing Problem
I have a netgear DG8234g router connected by ethernet cable to my desktop
computer which  I dual boot either windows XP or Linux.I cannot connect to the internet when in windows xp even with the firewall disabled.I can however connect perfectly when booted into Linux.
Further I have a wireless linked laptop running windows vista which also connects perfectly.
I would like to solve this problem with windows xp.
Thanks for  any help.
Regards

I have had no trouble with my previous providers and have just got this problem since moving to plusnet.

Have you checked you have the correct IP address, mask and gateway set in XP?

Check Windows TCP/IP is set to obtain IP automatically.
Verify settings in a dos box with ipconfig/all. Gateway should be your router and IP should be similar to the router with the last number different

Just to add to Peter's post - also check DNS points to the router, or to PlusNet DNS servers
