TrustedReviews posted a review of the ZyXEL Prestige 660HW router

The router is a compact box with a four port Fast Ethernet switch at the rear along with an RJ-11 port for the integrated ADSL modem and a reset button for returning the unit back to factory defaults. The wireless access point (AP) is endowed with a single aerial and MIMO is not supported. For higher wireless speeds you get ZyXEL’s Wireless g+ SuperSpeed technology which aims to boost 802.11g speeds to a theoretical maximum of 125Mbit/sec.
