Please don't recommend people pipe curl output to a shell. Yikes.
Wait until you find out nearly every modern package manager installs stuff directly from github repos.
Nope. See pkgsrc.
Recent Apple updates leading to WiFi issues?

Re: Recent Apple updates leading to WiFi issues?
#32I found just disabling these kind of Wi-Fi direct / local sharing features on macOS solved some latency I was seeing during online games. For example: Universal Control when enabled would cause the connection to choke for a few seconds when waking my iPad nearby.

#33I (used to) work in academic IT and I hate articles like this. People would assume there is a serious problem, turn off a bunch of services, run a bunch of random-ass shell scripts, and then forget that they'd done all that and at some random point in the future discover that some feature wasn't working, and blame me.
I just spent the last week diagnosing catastrophic Wi-Fi issues at a client location.
90% of macs wouldn’t connect to Wi-Fi, when they would association would take 45 seconds. Sometimes you couldn’t route or ping the gateway.
When you could you’d get disassociated within a minute. Turning off the airdrop/anirplay interface fixes it instantly.
sudo ifconfig awdl0 down
It took us 5 days to figure it out. We had no less than a dozen professionals on it. Each with at least a decade of experience. We combed the Wi-Fi and network config repeatedly to figure out what we did wrong. (It wasn’t till we had the hint that it was client side that we sniffed the nic to see the packet of death)
So I’m going to respectfully disagree. Articles like this are important. If I’d seen this last Monday it’d have saved me a week of hell and saved my client a week of vastly diminished productivity. Not to mention the tens of thousands of dollars spent diagnosing it and the millions of dollars of lost revenue from the deals they couldn’t close because calls kept dropping in the office (because enough people were on hotspots to saturate cell service in the area)

I mostly agree. But the article isn't the main problem, the sloppy script is. When I install such hot fixes, I have them check if the cause still exists (e.g. still running under Monterey?) and, additionally, add a timeout based on a date.
If you simply disable the nic apple helpfully reenables it 15 min later. There’s blame to be assigned here. Pretty sure it belongs to apple.

#35Their actual solution for disabling AWDL is running this script in the background: while true; do if ifconfig awdl0 |grep -q " That just checks the awld0 interface every second and turns it off if it's on. Apple really doesn't offer any other way to disable awdl? Note that setting AirDrop to "No One" doesn't fully disable awdl. It's used for other things like screen sharing, AirPlay, bonjour device/service discovery,…
I’ve been digging for a way to do this with defaults write and plists. So far I haven’t figured it out.
Re: Recent Apple updates leading to WiFi issues?
#36does this impact iOS wifi as well? My local HomeAssistant detects my phone on wifi for presence detection, and suddenly lately it's been all out of whack. it takes much longer to connect to wifi when I get home. and sometimes while home the presence status 'flickers', turning all the lights on/off. never used to happen
Could be. I've noticed my iPhone started to accidentally intermittently lose WiFi connection, only to reconnect again in ~3-5 seconds. I wasn't sure if this is iOS or UniFi AP bug, but I suppose it could be the former.
As it happens, I'm also on a Unifi AP, so that's curious. Would not hesitate to assign blame there... Although, I have long since abandoned their automatic firmware updates which has really helped with stability, so I'm not sure what would've changed on the AP _recently_.

I swear I really wish there were a way to output an entire OS's "diff" from default settings. Every preference pane, every terminal setting, every changed system file.
So that you could both discover, in cases like this, what's changed -- but also simply so you could export your settings in a space-efficient way and (selectively) re-import on a new OS install.

Information is important, but this post didn't have enough technical information about how to tell if this is your problem. How many people would say they haven't experienced “slow internet connection” or “drops in Zoom calls”? “entirely losing a WiFi connection” is less common but does that mean “it happened once and then it came back” or something like the hell you're describing.
That's important for the reasons the person you're responding to mentioned. I too have seen many problems caused by this kind of thing where someone had something they didn't like, made a ton of low-level config changes based on random blog posts, and then forgot about that when it broke something else.
Re: Recent Apple updates leading to WiFi issues?
#39I really really really wish that Apple would always use DHCP and get an open IP instead of assuming their last one is still good just so they can say they connect to WiFi 100 ms faster than anyone else. It is so infuriating and causes all the devices in my house to fight for their rightful slot.
Perhaps this is more of a problem with some router manufacturers/firmwares than others? I've had a bunch of difference devices running several different OSes (including several Apple devices) connected to a Netgear router running stock firmware for the past year and some change and have had no trouble at all.
Quite likely. Google WiFi notoriously had problems with Apple devices which they never bothered to fix. Switching to Eero completely resolved the random ~45 second hangs we'd see a few times a day.

This has gotta be some sort of HN meme at this point but... NixOS gives you this (with the tradeoff of course of a really steep learning curve and very opinionated packaging structure)!
