What's up all? Anyways heres the deal.. I'm not too computer savvy but I purchased a macbook today and im interested in using the wireless networking. I have a dell dimension desktop hooked up to the internet with a comcast modem.
I just wanted to confirm that what I need is called a router? But heres what im looking to do, im gonna throw this desktop away so I dont need internet on here or link em together or anything like that, I just want wireless internet on the macbook and thats it, no other computers. So would any ol router do the trick? Do I still need the modem?.. thanks..

Definition for Router from Wikipedia

A router is a computer whose software and hardware are usually tailored to the tasks of routing and forwarding, generally containing a specialized operating system (e.g. Cisco's IOS or Juniper Networks JUNOS and JUNOSe or Extreme Networks XOS), RAM, NVRAM, flash memory, and one or more processors. High-end routers contain many processors and specialized Application-specific integrated circuits (ASIC) and do a great deal of parallel processing. Chassis based systems like the Nortel MERS-8600 or ERS-8600 routing switch, (pictured right) have multiple ASICs on every module and allow for a wide variety of LAN, MAN, METRO, and WAN port technologies or other connections that are customizable. However, with the proper software (such as XORP or Quagga), even commodity PCs can act as routers.
Routers connect two or more logical subnets, which do not necessarily map one-to-one to the physical interfaces of the router.[1] The term layer 3 switch often is used interchangeably with router, but switch is really a marketing term without a rigorous technical definition. In marketing usage, it is generally optimized for Ethernet LAN interfaces and may not have other physical interface types.
