XV105,
If I understand you correctly, you can attach the uplink port of the DG834G wireless router to the ADSL modem, and in this configuration you can attach a PC to one of the 4 switch ports, with the PC able to connect successfully to the internet.
But wireless connections do not work - however, they do connect to the access point, do get an IP address and can ping the router.
Are both wired and wireless connections using DHCP? Can you resolve an internet IP address on a wired connection (e.g.
www.bbc.co.uk) and then ping that IP address over wifi? If you get a response then it's a DNS configuration issue. But if both wired and wifi are getting the same info from the DG834G DHCP server I'm damned if I can see why!
Do you have any security settings that prevent certain IP addresses from accessing internet resources through the router? I know on my Linksys I can block local IP addresses from getting to the internet - possibly you can do the same with Netgear.
