I want to buy an ADSL Modem/Router that has a 4 ports and a wireless point. I plan to have a pc connected via lan cable and a laptop connected via wireless.
Is there any modems/routers that will allow the PC to connect to other wireless networks via the modem/routers antenna.

I know if I install a wireless network card in the PC I can scan for wireless networks, but is there any modem/routers that have this functionality in-built?
