comment Why does network go down when access point reboots?
are your network switches running the spanning-tree protocol? What kind of switches are they?

comment Is there a way to enable minicom linewrap by default
I pulled pu linewrap after reading src/rwconf.c, so I just figured my understanding of C was broken. I hadn't tried -s. I'll file a bug. It's odd that minicom doesn't even understand its own config format

comment SOHO vs Enterprise AP for Network Interference
With basically no evidence beyond your personal observations, it sounds like co channel interference... Check whether there are unused channels with something like WiFi Analyzer on Android. Probably you have multiple 802.11ac APs hogging airtime which means your best options are a wire, or moving to a lesser popular location

I think you're underestimating how far you can throw 5G. I build industrial wifi solutions, and it will go through a sheetrock wall without problems... not as well as 2.4G, but good enough. Anyway... this is the joy of wifi, you never really know what the problem is unless you try 20 different things, or find someone who can run diagnostics

Please set up your airport for 5g only and let me know whether this improves the situation.

What kind of wifi card are you using? What kind of computer? Are you using 2.4G or 5G wifi?

comment Poor throughput to the internet but just fine locally.
So those "short bursts of dropped output packets" would (eventually) be detected by mtr. The switch doesn't care whether the packet is TCP or ICMP... it just has overloaded buffers and drops indiscriminately

This is certainly possible. The way for the OP to check this is to start an mtr on some internet host for 20 minutes before starting a large transfer (perhaps download an ISO DVD image). Now the OP has a baseline for his packet loss. Keep the original mtr running, and now start an ISO download. If drop rates change inside your home network, you have identified this answer as a strong possibility
