How to get round the mountain

RouterOS Beginner Basics
1

Hi

We live on a farm and have internet in the house closest to the road but want to route it to the main house as the telko lines never work.

We have 3 rb411 level 3 routers - can I use 1 in the middle and one on either side to get round the hill +/- 2km to middle and 2km up the mountain. (Found a place in the middle that has LOS to both sites and power is available from the pump)

Would I need to upgrade some of the licenses?
what config would the routers be (i.e. bridge/ap etc)?
Would I need 2 Wifi cards and antennas in the center unit?

Basics would also help just so I can get an idea how to go about it.

Thanks

No level 3 will be fine. You will need either 2 units in the middle or a 433. I would do 2 separate 411s because of self interference. For what you are doing, I would bridge it.
