My network is currently using a simple dlink dsl router for internet connectivity. I need two subnets and I need them to use the same dsl connection for internet access. I have a win 2k domain with 24 clients. I have a 1720 router. What kind of WAN connection do I need? (Do I have to have an ADSL WIC card or will something else work?) Can I use an ethernet card in one of the WIC slots so that I can connect a second network? Help.
