Numerous issues

We have just bought a Ring doorbell 3 after lots of reading and searching online, we decided on this one, and its completely uselessIts been up 2 days and lost wifi connection 3 times already despite being 2m from the router, it doesnt seem to detect any motion at all, we can come and go from the house and nothing is picked up, no matter what settings we have on or off, and live view very rarely works, 95% of the time it doesnt, despite signal strength being goodHave I received a faulty one ? Or are they always this problematic and we should return and get a different brand asap ?
