Below are the speedtests of two different routers using a wired connection.
Actiontec (about 2011) - 53.22 MB (down) 8.23 (up) Linksys WRT54G v2 (about 2004) - 23 MB (down) 7.76 (up)
Generally I like the older Linksys routers because I can install OpenWRT on them. With my faster internet connection they can't really stand up to new routers though. Worth checking if your router is the bottleneck in your Internet experience.
Speaking of new routers, I've been researching to buy with IPv6 support and preferably an open firmware out of the box. I haven't been able to find one yet...Buffalo is a great choice for the open part, but doesn't have IPv6 by default. In addition, the DD-WRT project appears to have stalled somewhat this last year. In an ideal world I'd get a router who's manufacturer officially loads OpenWRT and enables IPv6 out of the box. Am I missing said vendor?
