Wasted $350 on a wireless alarm panel that kept dropping signal every night

Bought a new wireless panel from a brand I hadn't used before (won't name them here but think budget-friendly). Installed it in a two-story house in Des Moines last Tuesday. Worked fine for three days, then each night around 2 AM the thing would lose connection to three of the door sensors. Spent 6 hours troubleshooting, called tech support, they blamed interference from the neighbor's wifi. Ended up ripping it out and putting in a wired panel. Has anyone else had luck with wireless in older homes with thick plaster walls?

Oh man, I feel your pain so bad. My husband and I tried a wireless system in our 1920s bungalow in Chicago and the living room sensor would just give up every time we made popcorn because the microwave apparently eats 2.4ghz signals for breakfast. I spent like four hours on the phone with their support dude who kept saying "have you tried moving the router" as if I could just pick up the whole house and shake it. Thick plaster walls are like kryptonite for wifi anything, I swear the stuff was probably designed in a drywall warehouse. You made the right call going wired, sometimes old school is just better even if it means running cables through the attic like a spider.

You said "microwave apparently eats 2.4ghz signals for breakfast" and that's actually not far off but let me clarify something. Microwaves do mess with 2.4ghz signals but usually only when they're running. If your sensor was dying during popcorn time that makes sense, but the original post says their panel dropped signal at 2 AM when nobody is cooking. That's more likely the plaster walls doing their thing or the panel just being a lemon. I've seen it firsthand on my mail route where people in older homes have all sorts of wireless quirks at weird hours. Plaster walls have that metal mesh lath inside that acts like a faraday cage, it kills signals dead no matter what time it is. And wifi interference from a neighbor's network is possible but honestly it's usually the walls themselves. Your point about wired being the way to go is right on the money though, sometimes you just gotta run the cables and be done with it.
