D-Link DIR-655 Xtreme N Gigabit Router

Pros: Even though it is a single band, 2.4Ghz, it delivers excellent coverage throughout the home; "n" just doesn't like walls inside or stucco exterior walls (over metal screen) for use in front or back yards. And you can add function (see below)

Cons: Can't participate in a WDS configuration to expand the network that way, however there are D-Link extenders that work with 2.4Ghz.

Summary: I'd had the DIR-655 for about a year and it was working fine, but I wanted to extend my home network to support control audio equipment throughout the house using iTunes as well as the new AirPlay function on our iPads. I purchased 2 Airport Express devices (with audio out), and assumed they would work best if I replaced the DIR-655 with an Apple Airporte Extreme dual-band router. That was a mistake, because the Extreme could not drive internet audio streams to any of my 2.5ghz devices (Internet radios, iPod Touch) without excessive buffering. I returned the Airport Extreme and decided to try everything with the DIR-655, and it worked extremely well. I can't extend my wifi coverage with the Airport Express deviced, but it's easy to purchase a D-Link extender for the 2.4Ghz DIR-655 (I have a DAP-1360 on order to do this). I have rediscovered the DIR-655 and what it able to do: provide excellent 2.4Ghz coverage and range, support all 2.4Ghz devices, and able to add advanced function like home audio control. I'm still getting all the wi-fi quality I had all along, and have added the ability to use my iPad to control home audio and also run AirPlay from iPad, iPod and iPhone to any sound system in the house (in addition to iMac and Win7 versions of iTunes). I'm very satisfied.
