Ubiquiti Amplifi the answer?

I have been looking at the Router recommendation thread: https://www.geekzone.co.nz/forums.asp?forumid=66&topicid=197871

I current have:

1x Huawei HG659, front of house, next to ONT, plugs into, the wired network, provides good wifi in the area.

1x Netgear R7000, other end of house, plugs into the wired network, provides good wifi in the area.

I do also need a reasonable connection on the far corner of the house though which I am not getting.

There is no practical way to run a cable and POE is unsuitable.

Potentially a nice clean shared configuration page would be helpful, rather than indivdual ones.

I think I need:

1x Ubiquiti Amplifi, front of house, next to ONT, plugs into the wired network, provides good wifi in the area.

1x Ubiquiti Amplifi, other end of house, plugs into the wired network, provides good wifi in the area.

1x Ubiquiti Amplifi, corner of house to complete the house coverage, meshes with other 2, provides okay wifi coverage.

Does this seem reasonable? If so, which 3 unit pack would best fulfill these requirements?

Do you have an alternative idea?

Cheers.
