This is one of the strangest knock-offs I’ve seen; they’ve totally borrowed the Linksys case design, but use a one-antenna board:

 

I’m pretty sure that even the B Linksys routers had two antennae.

In another project, I have my FON router operational. It’s in a DMZ and allows access to other FON users for free. Check out the web page, it’s a great idea.

The FON router is a WRT54GL, apparently it’s a Linux version of the WRT54G series. Older G series routers ran Linux, newer ones run VXworks. Mine is the router equivalent of putting “Classic” at the name of anything. 

I’m going to hook one up as the FON point, another as a router to handle PPTP services, featureful firewalling, and act as a border host.

Having a router running embedded Linux changes the way I think of appliance routers. Instead of a box with limited functionality, a finite development path and obscure featureset, linux routers are functional, expandable, can be extended beyond the manufacturer’s end-of-life, and are easy to understand if you know Linux.

The Netopia R- and 3500-series routers and SMC barricades I’ve loved over the years seem crippled by comparison.
