Virtual-Hideout posted a review on the Dynapower USA TP-LINK (TL-WR543G) 54Mbps and (TL-WR642G) 108Mbps A quote from the article:

Dynapower USA sent over the TP-LINK 54M Wireless AP Client Router and the 108M Wireless Router. Each of the routers have XR, or Extended Range, technology which can increase the range 2 to 3 times the normal 802.11b range. They both are designed for Small Office/Home Office wireless networks, and integrate Firewall, NAT-router and Wireless AP. The 54M Router additionally sports a 4-port switch. Not only designed for the Small Office/Home application but for those of use on a small budget.
