Performance on 5 GHz amazing, without any problem 660/700 Mbps 5 meters from AP.
Still 2,4 has a problem. Channel 40 MHz, max speed 150/170 Mbps 
Should be much more.
DFS for ETSI works fine.
Other tests in progress 
Hi, I have found a small bug with Wireless radio 1 and rates min-unicast + rates non-unicast + rates management, on my XE3-4.
If I log in to the CLI…
show config
rates min-unicast + rates non-unicast + rates management is missing on wireless radio 1… (Is this because the setting is “default”?)
If I then export my config from the browser in local management, I get this:
wireless radio 1
rates min-unicast default
rates non-unicast default
rates management default
However, I have changed this to 12 earlier with the CLI, and I know this is what radio 1 is using. So I don’t know why the CLI and exported config file says default. If I change something on wireless radio 1 in the browser, it will overwrite my old setting to default and rate 1.
This is only present on radio 1, not radio 2 or 3.
One thing that bothers me is “default”. It says nothing and should be the number the radio is using. On radio 1, default is 1, so why not just use 1.
One last thing, why did you remove the option to change rates in the browser using local management?
But enough negative feedback. On the positive side. My AP has been rock solid, no memory leaks, stable at 61%. Since last firmware upgrade, uptime was 52 days. Upgrade from 6.5.1… Temp on the radios is stable too.
Keep the updates coming and thanks for fixing other bugs 
Good job 
Please share the tech-support file of the AP you are using to adh100@cambiumnetworks.com.
Could you please let me know out of the 3 different rate configs which one you changed to 12 ?

This is only happening on radio 1 2.4GHz. I did check the config in the CLI now. Well everything is in order in the CLI. See below.
wifiax(config-radio-1)# rates show-applied
applied management rate: 6 Mbps
applied non-unicast rate: 6 Mbps
applied unicast rates: 6b Mbps 9 Mbps 12b Mbps 18 Mbps 24b Mbps 36 Mbps 48 Mbps 54 Mbps
So the problem is the UI/API, and it does not show the correct values. If the default is 6 Mbps, well then everything is correct. But then comes the question, how do you know what is default? Earlier, on radio 1 and 2.4GHz the default value is/was 1 Mbps.
Please do the following:
Thanks
