Unifi Wifi6, 11ac not included?

Looking at the new Unifi Wifi6 access points, to replace some very old Unifi BGN aps. Noticed the lack of any mention of 802.11ac wave 1 or wave 2 support.

Since 11ac wave 2 is also called “WiFi 5”, is it included in wifi 6, or skipped over?

I don’t have any Wifi6 devices but I do have a bunch of 5g 11ac devices.

Any input is appreciated.

According to Netgear, Wifi 6 is compatible with all previous generations of Wifi.


WiFi 6 routers are 100% backwards compatible with WiFi 5 and older WiFi devices

I’ve read the same, but what what I’m stuck on is the price, and uplink connectivity.

802.11ac wave 2 access points are rather expensive, 149US for the AP AC Pro, 349US for the AP HD and both have multiple gigabit uplinks. The WiFi 6 AP is selling for 10 more than their “lite” 11ac wave 1 AP at 99US.

Seems to indicate the WiFi 6 doesn’t support AC wave 2, but only wave 1?

I forgot what wave2 was in the end… beyond downstream mu-mimo.

In wifi 6, headline features IMHO are:

  • mu-mimo on upstream traffic (arguably way more useful than downstream - definitely an upgrade from 802.11ac)
  • wpa3 (and more specifically management frame protection parts of it are kind of nice, at least on paper various clients might have issues with roaming and encryption)
  • ofdma even on 5GHz
  • 6Ghz band… (not supported on u6-lite and u6-lr)

Specific difference to ap-ac-lite vs u6-lite and nanohd vs u6-lr, you get faster cpu cores inside especially on the lite which in ac versions was still selling with a 2010 era design single core mips cpu. This cpu difference adds about +50% performance on the lite. (haven’t tested myself, folks online report up to 700Mbps on the lite in ideal conditions)

I’m waiting on u6-lr to appear in stock in Europe before I order a few (early access hardware had DFS channels locked out, deal breaker for me and my house, production versions can use DFS channels).

Also, the two ubiquiti APs have a single 1Gbps port - to me that’s ok but it’s a deal breaker for some folks who were hoping it’d help them in high density setups like conferences and some classrooms (once those start happening in person again)

Thanks for the analysis.

At the price point for the “6 lite” AP, I’ll go for it, since it looks like a decent upgrade compared to the “ac lite” AP.
