This is a bit ridiculous. How can you know that you have a ling of sight element to you network and not check that as the very first thing when you hear about rain effecting the wifi?

It sounds fake, especially as the solution would be to get the original equipment higher, instead of buying new equipment? Also why not lay a cable.

It's just from some guy's office to his house, they aren't going to lay a cable across a few city blocks.

I had an experience like this once! My my laptop would inexplicably and intermittently stop connecting to the internet. It turned out my bluetooth headset was using the same band as the wifi but I only figured this out after a few months and a replaced wifi card. I wouldn't wish that experience on my worst enemy.

I have a fancy microwave that degrades my fancy bluetooth headset but not others. Did replacing the wifi card work? I'm wondering if I need to switch up my expensive microwave, or expensive headphone, because replacing bluetooth dongle (with another generic one with same chipset) hasn't resolved issue.

Microwaves use the 2.4ghz spectrum but typically not with any real precision which means that while in use they just tank the 2.4ghz spectrum.

*As an aside, one of my favorite things I get to do at work is when onboarding new Jr. Net Engineers is getting them take our spectrum analyzer into our office kitchen and instructing them to watch the spectrum turn bright red while I make a bag of popcorn.

Anyhow to get to your question, the best answer would be to get some distance between your microwave and set-up you're using with the headset. Otherwise if that isn't possible, then you'll want some headphones that does use 2.4ghz. Replacing the microwave will likely not fix the problem since they all use 2.4ghz band for cooking and at least I've never seen one shielded well enough that it didn't impact others while in use.

One of my most recent 'weird internet issues' was when I upgraded our 50mbit internet connection to 100Mbit and my laptop never really reached 100Mbit whereas my homelab easily got 100Mbit on speed tests.

It took me a while to realise the difference was that the homelab was physically connected and the laptop was using Wifi.

The laptop wifi was connected to the AP at ~1.2 Gbit and a different machine had the same issue. I decided to see what the internal network speed was and found that sending/receiving files to the homelab from a wifi device was also maxing out at ~90mbit.

This then steered me towards looking at the connection between the AP and the router, and I realised that the Wifi AP was connected at 100Mbit to the router instead of 1Gbit. Turned out the cheap CAT7 cable that I randomly used to connect Wifi to the router because it looked nicer than the existing cable was not actually a real CAT7 cable and only provided 100Mbit. Changing the cable fixed the issue! Out of paranoia I decided to replace all of my ethernet cables with decent quality ones.

I don't even remember where that 'fake' cable came from; probably from some random Aliexpress appliance that I bought at some point. I've had similar issues with USB cables that I've amassed, where I forget where they came from and only realise later that they barely fulfil their purpose.

I don’t think so. I definitely know tech people who get a particular idea in their head and will debug it to hell and back before taking a step back and realizing the obvious thing they missed. I’ve definitely done it before myself.

It sounds like they were trying to run a network between two properties that weren’t adjacent. They may not have had permission from the neighbor in the middle to lay cable on their property, or it might’ve required laying a cable across a street.

Raising the original equipment might not have been possible, and likely would've only been a temporary solution as the tree could keep growing taller.

Just regular Ubuntu. It was around 2009 or so.

Thanks. I've never run Asterisk on Ubuntu. FreePBX is CentOS based which is mostly what I've run Asterisk on. I only started to worry about Ubuntu around 2012. That mad IPv6 address thing must have stuffed up more than just a VoIP negotiation packet. DNS switches from UDP to TCP when responses get too large.

DNS is affected, but differently. It's mostly DNSSEC signatures that cause trouble nowadays.

SIP is special because the signalling and media protocols are separate. So when a call is being established, the parties exchange their media endpoint locations. This necessarily means that the server has to list its IPs (or DNS names) so that the client can choose the best one. And as a quirk of SIP, it sends the entire set for each of its supported codecs.

(Author here) Worse: to the balcony of our apartment building. Imagine asking your HOA how they'd feel about you mounting your antenna "higher" AKA on someone else's balcony or on the roof above someone else's apartment.

"Just" move it higher vs replace ~10yr old (at the time) equipment with newer, faster equipment that doesn't have the problem? Easy answer if you ask me, and I'd make the same choice again with ~10yrs of retrospect -- the same 802.11n antennas are still there today!

(Author here) Across several city blocks, in fact, and longer than the max range of Ethernet on normal (Cat 5/5e/6) cables.

Past ~300ft/100m, you need a repeater even for Ethernet. We would have needed at least one repeater somewhere along the line, which adds even more cost and complexity on top of needing to get permits from the city and approvals from all the neighbors in between. Anyone that says "just go get a permit from the city" has never tried doing it.
