I'm writing off my purchase. Even at the kickstarter price of $100, this was a huge waste of money. The hardware has potential, but the software/firmware is still alpha quality.
Even as a basic router, it failed for me. And I'm not even talking about the failed promises of sensor support...
Promises of updates, improvements, features, stability, and even a platform overhaul to a new linux kernel... and after over a year, nothing. The 5Ghz band is still unusable.
For the last 8 months, I'd downgraded to my old 802.11n router. Stable 'n' is better than unstable 'ac'. I put off buying a new router hoping that you'd finally figure stuff out.
Enough waiting. I decided to buy a real router. An Asus RT-AC88U. Newegg had it for a great price last Black Friday, so I cut my losses. I think people here would have just preferred honesty. Admit that you're not going to do anything. Admit that you've given up. Admit that you can't get the Cortana stuff stable. Then people could move on rather than continue to hope.
I knew there was risk with a Kickstarter project... But to think you're now selling this alpha product on Amazon.......
I'm out.
