I would like to run a second wifi adapter (either on USB-WiFi dongle or on the internal WiFi chip) on the VenusOS in AP mode and an isolated ip segment (no routing to LAN and the other Wlan network, dnsmasq dhcp, iptables blocking the traffic as an workaround if necessary). Venus manages the network settings and WiFi in client mode, not sure how to prevent it from trying to screw up the settings. Also looking for a way to force Venus to leave alone the manually configured default gateway settings - it screws them up and points default route on LAN instead of WiFi client frequently if one of the networks goes down and back up - what is verry annoying (LAN is connected to Raymarine St.HS isolated network, the chartplotter provides dhcp for 10.x.x.x addresses, Wlan connects to a 4G MiFi router or a phone with tethering for VRM portal internet access, both are often down or offline depending on network availability or devices turned off).
reason behind is, I want to set up an external router-independent wireless network for sensors, that continues to work if the router is down for any reason.
Any hints appreciated.
