Configured as Access Point, but I have a question

[BadGoose]

I have my WNDR4000 configured as an access point by disabling the DHCP server. That part is working fine.

Is there a way to give the WNDR4000 access to the internet by configuring it to point to the gateway. The options I still want to use the WNDR4000 for are:

1) DYNDNS
2) Firmware updates
3) Time Settings on WNDR4000

Thanks
