The UniFi will NOT work. 185m without walls is not going to cut it when within a house and you're trying to expand coverage by 250m.

Run cabling for another AP. Devices like tablets aren't necessarily powerful enough to work with long range access points. Another option would be to use a HomePlug kit to bring network connectivity to that space, then connect an AP to that.

If you don't or can't run wired connections, you can try linking up a wireless extender to your router.

A good example is TP Link, but there are cheaper options
