No internet with additional SSID and 2.4 Ghz Band
I've the latest firmware 2.8.5 and want to provide an additional SSID with 2.4 Ghz for my smart home devices. After I've enabled "additional SSID" with both bands, I see the new WLANs <ssid>_2G and <ssid>_5G. I can connect to both of them and getting an IP via DHCP. BUT when I'm connected with <ssid>_2G, I cannot ping neither hostnames nor IP addresses. When I'm connected with <ssid>_5G, I can ping both.
