These are great stories but awful experiences to live through. I am currently going through one right now. My wireless CarPlay connection shuts off whenever I drive past a particular highway section. It never happens anywhere else but this one area. There is nothing of note happening there (it's on a bridge over a lake) but just like clockwork, my entertainment system shuts down and refuses to connect. I have tried everything (reboots, firmware updates, wired connections, etc) to no avail.

While we're on the subject: I still can't solve this and thought you'd either laugh or you are the only people who know what I'm going through :) I have some fancy Asus Mesh wifi routers at home. I sit next to the cable modem and one mesh endpoint. My wife sits upstairs. there's an upstairs mesh endpoint but I think neither of us are usually connected to it (mostly serves to extend our connection to go to yard). But…

Strange as it may seem, try turning the power on each endpoint down. You may be getting signal from too many APs in the same place making the mesh elector freak out.

I wonder if some kind of jammer is running in that area. Reminds me of a similar story: https://www.theverge.com/2014/5/1/5672762/man-faces-48000-fi...

Weird that even a wired connection does not work. Stay curious!

I had one recently - old Nintendo switch; worked fine when docked, couldn't get an internet connection on wifi. Turns out it had been so long that the wifi MAC was picking up a DHCP address that was blocked at the firewall; the dock had its own MAC so it got a good address.

Were you using an Ethernet adapter? The original switch dock has a DisplayPort to HDMI adapter and USB hub. It doesn’t do anything with networking. The OLED dock adds ethernet (and therefore a second MAC).

Let me see if I'm the first one to link to that classic story in the same series, "I cannot send email further than 500 miles" http://www.ibiblio.org/harris/500milemail.html Or the Magic/More Magic switch http://www.catb.org/jargon/html/magic-story.html It's fun when physical reality meets the abstract models that we have built in our heads of these machines.

I had a customer who used a line of sight system for extending their network across part of a city. I had a shortcut on my desktop with the weather for that town ready when they would inevitably call and blame our unrelated equipment for some problem.

I worked at a small, local ISP in the 90:ies that had a point to point link across the river, handling the dial up traffic from the telecom company we partnered with.

Every few days, always at roughly the same time, all incoming dial up traffic would drop. A minute later, the customers could reconnect.

It took a while before we realized that one of the huge passenger ferries that docked a short distance upstream was the cause. When it arrived and departed, its chimneys and possibly bridge and highest deck blocked LOS across the river.

The unusual internet setup is pretty important information to bury a few paragraphs in. Once that was explained it seemed like they should have started by checking nothing was blocking the antenna before tediously running around plugging the laptop into things and following cables and checking power supplies on the networking equipment? Hindsight is 20/20 but I correctly guessed the ending as soon as that information…

There’s troubleshooting and then there’s the troubleshooting of the troubleshooting post-mortem. GP is just doing the latter.

EMI maybe? Certain chairs cause monitors to go blank for a few seconds. https://mastodon.social/@haeckerfelix/110272427676278609

I think my chair does this, but only when I'm not sitting in it. Maybe my body absorbs the ESD? If I'm doing anything nearby and bump the chair there's a good chance my monitor will lose signal for a second. It happens with both HDMI and Displayport with a number of different GPUs and different computers. The USB-C connection has never had a problem.

I'm in an older home with questionable wiring which I'm sure is also a factor.

I'd replace the chair but it's so dang comfy.

My first thought as well was there could be something emitting an intense signal in the vicinity that is interfering with the connection. However, there does not seem to be anything nearby (like I said, it is on a bridge going over a lake).

I have a hard time believing this. Wifi can go through multiple walls. And if these were directional P2P links, they can easily go through and even around trees, I've deployed them in the past and they don't need perfect line of sight. Granted the equipment could have been cheap, but this sounds questionable. He's asserting that the a few leaves at the top of a tree were blocking it when it wasn't raining? Idk.

I cannot know whether the story is true, but wet leaves definitely would interfere more with the link. The typical water content (and conductivity) of tree leaves is relatively low, and it could also be a factor apart from the aforementioned sagging due to the water's weight.

It is also true though that rain water has low mineralisation, and therefore low conductivity.
