I believe it's a V1 given that it doesn't explicitly say V2 after the model # and the power is 4.0A vs. the V2 which, I believe, uses 3.0A (referencing DSL reports).
Looks like the price went down, hot deal now! I use one of these and it's been fantastic, the wireless covers my entire house and lawn. Never had to reset it and the stock firmware has been rock solid even while I have Torrents being shared 24/7.
