Problems from the start

Where do I start, so my router is at one end of the room and the ring is at the other end (outside) yet it won’t pick the signal up. It did before my husband drilled holes on my front door, now it doesn’t. When it does work it’s jumpy and freezes, the wind noise is crazy, I can’t hear people talking at the door. Then it rained and I couldn’t see anything on the screen but drops. I’m baffled, I’m going to try return to the shop tomorrow, it’s not useful at all.
