I have a new expensive mesh router system and it didn't work. I've replaced my modem at significant expense, had a cable company tech switch the active cable's output to a more central location, added an amplifier - no improvement. I ended up replacing the coaxial cable that came with the modem and. yes, a little embarrassed that I didn't try it first. This cable fixed everything. With the other, I couldn't get a signal between the front door ring and the router 10 feet away; I use this to signal a ring doorbell across the street at my neighbor's house - he allowed me to install it under the roof of his garage to capture the parts of my yard that the house's cameras can't see (around bushes and trees hereabouts). Next time I'll start with a simple solution.
