OpenWrt 18.06.4 connection problems with WPA2-EAP

[justin-af]

Hello together,

I have connection problems, when I am connected with my wifi network. I am using the encryption method "WPA2-EAP" and a seperated Windows RADIUS-Server. I am loosing the connection and my IP after 1 or 2 hours. I have to wait a few minutes and then I am reconnected. The AP (Linksys WRT3200ACM) is only a pass-through to the RADIUS-Server. I also have two other networks (BYOD & Guests) with the encryption method "WPA2-PSK" and there are no connection problems. I am using "OpenWrt 18.06.4 r7808-ef686b7292" and "wpad 2018-05-21-62566bc2-6". I also checked the logs form the Windows RADIUS-Server and there a no errors.

My wireless config:

        config wifi-iface
	option device 'radio1'
	option mode 'ap'
	option ssid 'RADIUS-NETWORK'
	option network '115_RADIUS'
	option disassoc_low_ack '0'
	option encryption 'wpa2+ccmp'
	option auth_server 'XXX'
	option auth_secret 'XXX'
	option ieee80211r '1'
	option ft_over_ds '0'
	option ft_psk_generate_local '1'
	option nasid 'AccessPoint5'

Having similar issue with openwrt 19.07.6 WPA2-EAP -> Pfsense FreeRadius3 0.15.7_26.

Randomly, devices lose internet access, and I have to restart wifi on them to make it work again.

Having the same issue. Anyone got this working?
