Failed to load integration when router does not have WiFi

[harsh2029]

I have a NanoPi R5S as a router and external WiFi access points. This router does not have WiFi and hence no iwinfo or hostapd installed. When I load the integration, it always tries to read the network.wireless path which is obviously not valid and results in Access Denied (-32002) error code.

It would be great if integration has an option to add router without WiFi interface.
