How practical is using a Wireless-N router together with a B and G router?

Question

I hope to use a Wireless N router to boost up the speed of wireless Internet, but there are some device that probably only supports B or G, such as iPhone, iPad, Wii, so if it is to replace the existing Wireless-B/G router, then some device won't work.

Is it practical to buy a Wireless-N router, and then just plug the existing wireless router to it, or if I am using AT&T's u-verse, which has a central Wireless-B/G router, then plug in a new Wireless-N router into it?

Answer 1

Most Wireless N routers also support B and G so you shouldn't need to chain your routers in order to provide the backward compatibility.

Wireless N is not going to give you better throughput for your Internet connection, though, unless your connection gets higher than ~50mpbs. It'll certainly give you better throughput between your PC and the router, but the Internet line is still going to be your bottleneck. Currently AT&T Uverse is offering up to 24mbps which is well within the limits of Wireless G. A Wireless N router is not going to serve that to you any faster than a router with Wireless G. The only benefit you'll get from the Wireless N is better LAN performance.
