Hello,
I recently asked how to bridge WAN connections between two internet sources. The answer to that question leads me to ask this question.
How do I connect a Virtual wlan interface to another WIFI ?
Soon I will have a broadband connection via the telephone network [in addition to the LTE 4G one we depend on]. To load balance between the connections will require a connection between the cellular router and the landline router. The easy way would be to cable between them but this is not possible. Since the cellular router also provides our WIFI and is heavily configured beyond the scope of this post, I do not really want to change [destroy] any of the existing configuration of this router. The landline router is provided by the ISP and so its configuration is heavily restricted to only the basics, which for what I need of it, should be fine.
I am therefore wondering how I connect from the “cellular router” to the “landline router” as a WIFI client, from a virtual WIFI interface. I [think I] don’t want to bridge the connection since it needs to be transparent to clients which WAN their request is ultimately transmitted on.
I am not very familiar with Ros7.3.1 which I am running. I am wondering what steps are involved to do this?
I tried just adding a Virtual Interface in Station Bridge mode, but frankly I am shooting in the dark here.

Thanks.
