Per another customer, here's the differences in the Extremes:
The following will likely save you a couple of hours of research...

The DIR-655 is single-band (2.4GHz).

The DGL-4500 is dual-band (2.4GHz and 5GHz), however it only uses one band at a time. You choose which band, manually, in the configuration. It doesn't choose the best band in real-time, or anything like that.

The DIR-855 is dual-band (2.4GHz and 5GHz) and uses both bands at the same time.

Great Router
The DLINK DIR-855 router is the best router I have purchased to date. I originally thought I was going to have problems with weak signals and the like, but I found that it was the older hardware that I had trying to connect to it that was the problem. Some of the older technology was having a hard time staying connected if it even saw the router at all.

The router is somewhat easy to configure with the included configuration wizard on the CD. I did this using a Vista PC and did not have any problems. For the more advanced configurations, DLink provides the standard and easy to configure web-based browser access configuration screen.

What is odd is that everything I read touts using the 5Ghz range if you can, but that signal is weaker overall even with newer hardware connecting to it. It is a good 10% less. Regardless, my laptop connected easily enough and reports a full 300MB of throughput. Like I said, I did have some older DLink bridges that I was using to connect to my DGL-4300. At the exact same distance with the DIR-855, one bridge could see the router with a 15% signal and the other couldn't see it at all. I replaced those with the DAP-1522's and all is well now.

For those who want to know, this router does not support WDS which is a dissapointment if you want to use older DLink routers to bridge to this. They state in their forumns that they do not intend to add WDS later.

I work at home and need the bandwidth, so if you do as well, this is a great product and very much recommended.

The best router I have ever used
This router is awesome. It is faster than anything I have ever used. I have Comcast cable internet service. The setup was a little tricky (using both Vista and XP computers), but I managed to hook it all up. The range is incredible. This replaced a Linksys WRT54GS router with HGA7T antennae, WRE54G range expander, and WPS54G print server. The price is high but it certainly does everything I need it to do, and more.
