Well, for one, I'm not tech support. Secondly, I take offence when people are being rude, racists and impolite on the forums.
If someone is so unhappy to the degree shown here, I'd rather offer a refund than argue points or ask them to wait for fixes, yourself included.
As for the beta/dev backers, most of them, we never heard from, that's not really our fault, as we can't force people to actively take part in a beta/dev program that they've paid to join. Nor can we force anyone here to upgrade their firmware for example. There's something called free will and if people aren't willing to do things, we're at no point going to force them to do so.
As for your specific unit, it's possible that there's something wrong with it. Can you give some actual performance figures instead of linking to a review of an unrelated non AC router?
Without any specifics, I can't say even begin to guess what's going on.
Also, as you might've not noticed, we've pointed out in the firmware release notes that the Wi-Fi performance hasn't been optimized as yet,
It would also be good to know what your client device is, as without knowing that, it's hard to say what kind of performance you should be seeing.
That said, I personally only own once 802.11ac device, my HTC m8 and I can max out my 120Mbps internet connection using it and we've tested much higher speeds than that using the current drivers/firmware.
Yes, maybe I stepped out of line a bit, but we're trying to help people get their product working and then getting rude comments just because someone doesn't like the way we've set something up to try to prevent spammers, rude comments about our support team based on where they're from/where they're located, etc. is simply not something I'm going to put up with.
If you have legit concerns and issues, we'll deal with them and get them fixed, but certain things takes time for us to figure out as to be frank, we didn't find these issues during our internal testing over the past year or so, so many of the issues caught us with our pants down for a lack of a better description.
At the end of the day, if someone is so unhappy that they don't want the product, we're willing to issue refunds, but we can't pay for the return postage in these cases, as we've already sent a product out that costs more than what was pledged. Admittedly that is our won fault, as we made the changes, but at the same time, we've delivered more than what was promised when we started the Kickstarter campaign.
I'm sorry if I was offensive, but I'm working 7 days a week trying to help everyone out regardless of what the issue might be and when I get enough lip, I need to vent sometimes too, but maybe this was the wrong place to do so.
