tplink Tp-link 210 Access Point issues

[NonSlipSurface]

Heya,

I've bought two APs in the title to connect one house to the other into a one network. The first house has a new fiber cable with router and everything and from that router theres a new cable to the AP on the roof. 

Second AP is setup to be a client, the cable is used from the previous antenna, but tested and working. 

Issue is the internet in the other building (with client AP) keeps disconnecting randomly for few seconds, up to a minute and i cant figure out why.

There's a tree on the way from one ap to another, but shouldn't be much of a problem, since there are no leaves on it in November

 

Any ideas what might be causing this issue and how to fix it?

Perfect line of sight? How high up from the ground?

What about the rest of the tree? Would it be in direct line of the signal between the two antennae?
