2 internet connections and multiple networks - how to choose

Hello,

We have problem in our network, we have 2 internet connections, ADSL is faster and expensive (no flat rate), and WiFI connection which is slower but has a flate rate.

I want to connect users from my 10.10.0.0/24 network to just one of those connections, for example one who is need a lot of download will connect to WiFi connections

Line’s are connected to 10.10.0.13 - ADSL and 10.10.0.11 WiFi,

I have put default gateways and for ADSL distance 0 and for WiFI I put distance 1.

These interfaces are not in bridge. Do I need to put them?

Version of router is 2.9.27

Load balancing? Other solutions?

Thanks
