i got mine too!
just flashed to the latest big build of ddwrt, everything went smooth. its working great!
off to best buy to take the wndr3700v3 back! $108 back in my account thank you very much. kinda sad, because that 3700v3 router is excellent imo... i mean everyone is scared shitless of getting a v3 but thats only because ddwrt isnt supported (yet!). in fact, its an awesome router and the stock firmware is very good too after it auto updates.
but money is money, and this e3000 is about the same exact thing for half the price.
i do notice, the e3000 does seem less efficient. the netgear 3700v3 requires 12v@1a max.... while this e3000 has a 12v@2a adapter. the e3000 definitely does run a lot warmer too. i dont want to say much more then that, because without actual amperage testing who knows whats really going on, but it seems the e3000 wastes more energy in the form of heat.
im a realist though, and if that means i have to spend an extra $2 a year to run this router then so be it. if this router breaks i can buy another one. if that netgear broke its a lot bigger investment lost.
