I received version 9.1. 4MB flash, 32MB RAM, and 550Mhz Qualcomm Atheros QCA9533 processor. 50Mhz faster than v8. DD-Wrt only officially supports up to v8 at this time, so have to rely on beta drivers.
DD-Wrt compatible; Inexpensive (PM'd it to $25 after tax; Gets only slightly warm by itself; Power block thin enough to take only 1 slot; Power and wireless on-off switches
All 100mbp ports; Idealistic advertising of 300 Mbps like other wireless N Routers; No detachable antennas but it doesn't matter to me; Will need beta DD-Wrt drivers for version 9.x
