Login to the AP cli and execute following command to verify the current mode of the AP:rkscli: get mode wifi1wifi1 Mode: 11aheOK
The ahe mode shows that the AP is operational at ax rates. To change the current mode to AC, use following command:rkscli: set mode wifi1 11ac
Verify the mode change using following CLI:rkscli: get mode wifi1wifi1 Mode: 11acOK
This will probably fix the issue.
