I've had issues with the last several routers, so I recently bought the very first, 100% OSS router. My thinking is that if it's open source, it's probably high quality code, and it's more likely to get updated than proprietary firmware, where they are cash incentivized to just have you buy the new router rather than fix old bugs.
As far as hardware goes, it's mid-range router hardware, N300 Wifi with respectable antennas and a ho hum 100 Mbit hardware switch. The UI was a little odd, more complex and far more options than your typical Wifi router interface.
However, in the month or so that I've had it, it's been the least problematic Wifi I've had in a few years. I live in a densely populated area with quite a few other hotspots in sight, and I haven't noticed any issues where restarting the router made a difference.
I haven't had the chance yet to hack it, but even as just a router, this is a winner. Also, support products that are consumer friendly like this one. It's not even more expensive! (Currently just $52)
