"Portal is the first and only router specifically engineered to cut through and avoid congestion, delivering consistent, high-performance
WiFi with greater coverage throughout your home.

Its proprietary spectrum turbocharger technology provides access to
300% more of the radio airwaves than any other router, improving
performance by as much as 300x, and range and coverage by as much as
2x in crowded settings, such as city homes and multi-unit apartments"<= br>
It sounds like they are promising working DFS support.

It's not clear what chipset they are using (they are claiming wave2) -<= br> but they are at least publicly claiming to be using openwrt. So I
threw in enough to order one for september, just so I could comment on

I'd have loved to have got in earlier (early shipments are this month apparently), but those were sold out.
