I got my router about a week ago, and it's been running really smoothly, just like my previous di-614+. But the new one i got is revision B2, and it does come with only one external antenna. The router itself is also much smaller, I'd say by at least 25%. Looks much better than the bulky old one that I had, which was revision A2. The configuration utility in this revision B routher is also much more advanced. It has a lot more configurable options, such as setting beacon intervals, setting the power of your antenna (so if you have a small house, you put it at a lower setting so neighbors can't get onto your network, hence providing more security for you), turn off ssid broadcast (again, for added security), etc. It actually has just as many functions as the cisco router that I've played with before, and those sell for the many hundreds of dollars. So I'd say this deal is definately flaming!
