EAP610 seems to be using only 802.11a instead of ax
My single EAP610 AP seems to be using 802.11a only. All my network devices appear to have slow connections, and Windows reports the protocol used on my network card is 802.11a. I confirmed with my phone that the speed is limited to 20mbps download. I've checked the AP settings, and the IEEE802.11 Mode is set to b/g/n/ax mixed. It was working fine yesterday, but now everything has reverted to 802.11a. How can I fix this?
