this is /etc/config/wireless

	option type 'mac80211'
	option path 'platform/18000000.wmac'
	option channel '1'
	option band '2g'
	option htmode 'HT20'
	option cell_density '0'

config wifi-iface 'default_radio0'

config wifi-iface 'default_radio1'
	option device 'radio1'
	option network 'lan'

	option ssid 'netware-5'
	option encryption 'sae-mixed'

any thoughts ? suggestions ?

Encryption "sae-mixed" corresponds to WPA3, and that might cause incompatibilities with some devices. Try with WPA2.

never do you mind, i changed encryption from sae-mixed to psk2, and it just worked !

exactly, i changed to psk2, that worked like a charm, thanks for the reply @eduperez

Likely you need separate wpa2+aes accesspoint annd force printer to wpa2+aes only.
