I've had the same problem over the years with the last 2 years occurring only
during the months of January & February.
It's always slow to deteriorate, over a few weeks, from a optimal distance of
200' ending with having to be right at the door pressing multiple times.
Changed all batteries, reset, & reprogrammed to no avail.
This year I systematically threw breaker by breaker & never did isolate it.
Bought a new main board for the opener with no joy. Problem just went
away in March. I have a heated entry floor thinking maybe it was seasonal,
but that was not it. I've heard that routers can interfere. Was thinking it
was
the neighbor's house which is a rental, but different tenants last 2 years.
Very frustrating ..... but at least my oven never came on.

For years I've easily opened my garage door with the car's remote system from
400 ft. away. A few weeks ago I noticed that was no longer possible. Even
from my own driveway it was often hard to open it. I had installed a couple
of 11w LED bulbs in the main motor unit. I had no concern, since I have 35
Cree LED floods in my house that do not create noise beyond a few inches.
This was different. Those bulbs generated noise in the 300Mhz spectrum that
interfered with the reception from the remote. Replacing them with 23w CFL
lights solved the problem. Beware of LED lights in a garage door opener!!!
