Wifi jamming is an easy thing to do, as the whole 2.4GHz band works on the assumption that everyone is nice to each other. One non-cooperative device, and everything in that band goes down: Wifi, BT, Garage door openers, Car key fobs…

Vehicle fobs are usually not in the 2.4Ghz range, they’re usually in the 300-500mhz range.
But yes, there’s a lot of assumptions and usually it’s right, but it can be wrong also.
Also, fun fact, microwave ovens use very high power 2.45Ghz. so they can do this by simply rigging a microwave to turn on when the door is open, then pointing it at your house at a safe distance, like across the street.
Most companies that make outdoor stuff generally avoid 5Ghz because it’s a regulatory nightmare. Some countries allow it, others only allow certain frequencies, others only allow certain frequencies up to a certain power level, others basically don’t allow it at all. So all your fancy door bell/cameras/whatever that you connect outside your home are all going to be limited to 2.4 GHz with is basically universally available internationally (it’s an ISM band, while the wifi 5ghz is a UNII band)… So yeah, good luck everybody!
Also wired cameras and such exist, they’re a pain to install, but they work well, and the market for other outdoor network connected things is extremely limited… Things like doorbells.
I hate putting static objects on wifi, even something like my TV, I want it wired simply because it never moves and there’s no reason to use it wirelessly. I can run a wire to it once and even if I upgrade the TV, the wire still works. To explain this a little more, I’m an IT administrator and I have a specialty in wireless networking. As tersely as I can: more stuff on the WiFi makes it slow, so if something can be wired, it should be wired. Obviously there are things that are not well suited to it, like cellphones and laptops, but pretty much everything else should be wired. TVs, set top boxes, desktop computers… Basically anything that can be wired, that doesn’t regularly move around… Wired. This extends to cameras, doorbells, gdo’s…
This frees up wireless bandwidth for devices that are obligated to use it, like your phone and tablet.
I’ve seen a lot of network issues resolved by simply plugging in everything that’s practical to plug in, even if the device having the issue wasn’t one of the things plugged in.

Yeah, i always try to connect as much as I can to ethernet cables. The issue being that it’s sometimes a pain to install the cables, especially if you’re renting and can’t really pass wires through walls

My solution when I lived in an apartment was to buy cup hooks, and white ethernet cable (either riser or plenum), as well as some ethernet wall boxes, and keystones for them. For a bit of flair, I also picked up some white hook&loop (aka velcro).
I added a few lengths of conduit/raceway for vertical runs and what I did was use the cup hooks to create a wiring tray for ethernet cables along the ceiling lines on the wall… Maybe 2 inches from the top, every 18 inches or so, I’d put a cup hook. Then, when they were placed, I ran the raceway up the walls near my network stuff, and used all of that to wire ethernet around the place. Cup hooks are self tapping, you generally don’t need any tools for it. I “pre-tapped” the holes with a small nail, just driving it in less than half an inch, then pull it right out… just to give the cup hook somewhere to bite into and set my positioning for it. The larger cup hooks can carry 4-5 ethernet, and I used the velcro to keep everything together and tidy.
On the ends, I terminated the cables to keystones, mounted them in their wall box and stuck it to the wall with 3M command strips, for easy removal later.
For me, the cables went along the base of a wall in one bedroom which we used as a computer room/office, over to the door, around the door hinge at the bottom, up the wall using conduit/raceway, along the ceiling of the hallway, over to the living room where I had two wall-mount dual ethernet boxes for four cables/connectors. I then used standard ethernet cable to run to my TV, a wireless access point, an htpc, etc.
The only other stuff in the living room was phones and other appropriately wireless equipment, the rest of the wired stuff was in the office. The TV we had in the bedroom had a cable that went through the wall to the office. I found that a telephone wiring box on the walls between the rooms was open on both sides, so I just popped the faceplates off and ran the cables.
I know my situation is unique and yours will be different. I’m hoping I can give you some ideas on how to tackle the problem without initiating aggro from either the spouse, family, or landlord.

Holy shit there’s a lot to unpack here, thank you so much for the suggestions!
Honestly in my case the issue is really that I don’t want it to be in pain to restore the flat when I leave it, and it’s rather small, I just need to pass a cable along the hallway into my office, and somehow pass the door which really does not have a lot of space around it (not enough for a standard ethernet cable, so I’m thinking about flat ethernet cables, which could work here)
But I haven’t really had time to think about it yet

I always find it a bit amusing when I see “shut down due to radar activity” in my 5GHz logs.
MystikIncarnate@lemmy.ca 7 months ago
Aah yes, that’s UNII-2 in action. You can’t have a radio in the UNII-2 band without some measure of radar detection and avoidance. It’s a regulatory standard. Most will simply hop to another frequency and inform connected stations of the move, but shutting down when radar is detected, is valid.
It may be worthwhile to aggregate such reports and see if it’s the same few channels each time, then simply exclude those channels from being selected by the system. It could increase the reliability of the connection to the clients and reduce any calls about the wifi going out or kicking people off of it.
