@jakup Make sure that the laptops get their IP address dynamically by C64 DHCP server. Disable the C64 Access Conrtrol feature (if enabled) and don't use its IP & MAC address binding feature.

@yiz You can't directly, but here's a thread discussing a possible workarounds. The other way to do this is to use the Tether app for remote management.

@Karooplaas Any wireless router in AP mode can be used to extend your wireless coverage further using the ethernet cable - details.

@yiz Compare your AX72 Pro Internet (WAN port) IP address with the IP addres from https://ping.eu - they should be the same. If they are not the same then you're behind CG-NAT and this won't work.

@siens You could disable WebGUI HTTPS access for local management only. Thus the browser warning message shouldn't appear anymore.

@Diggery Have you went through the troubleshooting guide for VPN Client not working.
