Password for internet access via ADSL router?

I have a Netgear ADSL router and usually access it wirelessly. I am aware that it's vital to have physical security for the router because anyone who has access to it could connect via an ethernet cable.

Does anyone know of any ADSL routers which require a password to connect to the internet if used with an ethernet cable? When I set my router up, I had to enter the username and password which were provided by my ISP. I've tried deleting the password and then rebooted the router and computer. As expected, I couldn't connect to the internet and I wasn't presented with any sort of password dialogue.

Thanks for your time.

The equipment you have won't do it. You'll need an authentication proxy to do this or a firewall that will authenticate your connections.

I'm not sure which Netgear you have, but you can get routers which allow/deny access based on MAC address. This would normally be an expected feature in more expensive adsl routers but can also be found in Linksys routers and any router with DD-WRT firmware.

I have a Netgear DG834G and have set an access list by MAC address when connected wirelessly. This reduces the chances of someone connecting without my authority (I've also disabled SSID broadcast, enabled WPA and know that MAC addresses can be spoofed). A good solution would be to have a similar facility when connected (or trying to connect) via ethernet cable. I'll look into these router suggestions - they seem a little more "novice-friendly"!
