The Acer Chromebook Plus 514 comes equipped with a WiFi 6E NIC; we have purchased 3 of these new yesterday and are unable to connect to 6GHz in any manner which could be considered reliable.
We have 2 SSID's configured for WPA3-SAE PSK on 5GHz and 6GHz across a mixture of Ruckus R670 and R770 wireless APs. The Chromebook 514's exhibit behaviour of connecting to the SSID successfully approximately once in every 30 attempts; they will then disconnect shortly after and repeat the same 1 in 30 connection success rate.
There are no visible logs on the Ruckus AP's; so apparently the AP's do not see the Chromebook 514's even trying to connect.
I have isolated the problem to being the inability of the Chromebook 514's connecting to the 6GHz radios. I created 2 additional SSID's, SSID 1 is WPA3-SAE PSK on 5GHz only, and SSID 2 is WPA3-SAE PSK on 6GHz only. The Chromebook 514 will connect without problems to SSID 1, but will never connect to SSID 2.
We have approximately 120 other devices that are successfully able to connect to the original SSID's (5 + 6GHz WPA3-SAE) without issues; and are a mixture of Windows, iOS, Chromebook Flex, Android; many of which are successfully connecting on 6GHz.
