can a router do this?

FTR: Connectify Marketing bumph from when I dl'd the previous version (they've just released 3.1):

Connectify is an easy to use software router for laptops and smart phones. With Connectify, users can wirelessly share any Internet connection: a cable modem, a cellular card, or even another Wi-Fi network. Other Wi-Fi enabled devices can see and join your Connectify hotspot just like any other Wi-Fi access point and are kept safe and secure by password-protected WPA2 Encryption.

* Take any Internet connection and share it wirelessly with no additional hardware, wires, plugs, or chargers
* Easily connect any number of Wi-Fi enabled devices to your network including desktop computers, laptops, phones, gaming systems, and more
* Don't break the bank paying for multiple Wi-Fi connections on the road, Connectify is ad-supported and free to download and use.

Connectify can easily act as a repeater for your home router, extending its range and providing Internet access wherever you need it. Connect to your home network, enter the same Wi-Fi name and password, and hit "Start Hotspot." Devices will automatically connect to the Internet through either your Connectify hotspot or home router depending on proximity. Before you know it you can finally have Internet access in that impossible back room or basement. In addition, if you run Connectify away from home with these settings, any devices that need to be bound to a specific network (such as Eye-Fi cards or wireless printers) will work flawlessly with no additional configuration no matter where you are!

A simple wireless router can do all that. Just make sure you wireless router is connected properly to your modem.
