Hi,

Please try connecting to the router via SSH and running the following command to add a Guest MLO SSID:

# Keep the original files for rollback.
[ -f /root/wireless.before-guest-mlo ] ||
    cp /etc/config/wireless /root/wireless.before-guest-mlo
[ -f /root/mlo.before-guest-mlo ] ||
    cp /etc/config/mlo /root/mlo.before-guest-mlo

GUEST_MLO_SSID="$(uci -q get wireless.guest2g.ssid)-MLO"
GUEST_MLO_KEY="$(uci -q get wireless.guest2g.key)"

# Generate four different local/unicast MAC addresses and avoid existing ones.
while :; do
    TAIL5="$(hexdump -n 5 -e '5/1 ":%02X"' /dev/urandom)"
    MAC2="02${TAIL5}"
    MAC5="06${TAIL5}"
    MAC6="0A${TAIL5}"
    MLDMAC="0E${TAIL5}"

    uci show wireless | grep -qiE "$MAC2|$MAC5|$MAC6|$MLDMAC" || break
done

# Remove only an existing manual Guest MLO configuration.
