I've finally found an answer:
MacBook Pro experiencing ping spikes to local router
I've done the following:
Enable Wi-Fi logging
Perform ping: ping 184.108.40.206 -i 0.1
Check for changes on wifi log after ping spike: tail -f /var/log/wifi.log

After consulting with Apple it turns out that
Automatic sync should happen every time the phone plugs into the computer while iTunes is running
None of my the iTunes installations did this on macOS or Windows, which is an error
To work around this required manually syncing a folder with a photo in it to the phone, on both windows and macOS separately. ...
You are connecting to a WPA2 network in WPA-PSK (pre-shared key) mode. In this mode, you'll usually be able to authenticate by entering a password as a string of ASCII characters (up to 63 characters). macOS will generate a 256-bit authentication key from the password using a series of manipulations (known as salting and hashing) that ensures that ...
The Service Order doesn't work. If you test it, you will find that Mac OS prioritizes Wifi over Ethernet, even if Ethernet is set higher in the Service Order.
One way to test it is to measure your bandwidth (e.g., https://www.fast.com) in the following scenarios:
Connected to Wifi, with Ethernet unplugged
Connected to Ethernet, with Wifi turned off
From within macOS, no you can't.
If you don't unlock System Preferences you can't add or delete a Wi-Fi access point.
As you can see you can't select a Preferred Network and the +/- is locked.
Neither can you do it from command line.
You can add a network with sudo networksetup -addpreferredwirelessnetworkatindex en0 whateverNetwork 0 WPA2 ...
Step 1: Find out device ID of Wi-Fi
$networksetup -listnetworkserviceorder | grep Wi-Fi
(Hardware Port: Wi-Fi, Device: en0)
In this case it is en0
Step 2: Create a "Quick Action" using Automator.app. Set "no input" in "workflow receives" in "any application". Drag and drop "Run Shell Script" and add the following shell script to the text field.
I am experiencing something similar, and it is actually the Apple Magic Mouse 2 that creates all the interferences with other Bluetooth devices.
I guess something got very wrong in my mouse. If it is on, no Bluetooth device works properly
There is a lot of different things that can be the reason but I suggest you simply
Open System Preferences and make sure Show Wifi status in menu bar
Then while pressing the option key, click on the wifi icon in the menu bar.
Select Open wireless diagnostics.
Follow the on screen instructions and you should get your answer there without
Just to make sure... Is visibility for 5G Wi-Fi network turned on? I.e., network is visible in the list of available networks, when you want to connect from any other device?
Also, try this:
Turn WPA2 only in the router settings..
Remove saved 5G Wi-Fi network on MBP and register again.
Just in case, make sure your MacBook supports 5G connectivity by:
You can also put it as a script for all apps and use Script Editor's menu bar button which sits close to Wi-Fi button. ~/Library/Scripts is the folder where the scripts are accessible to all apps.
There’s nothing that allows you to kick off a script when you attach to a particular network, so you’ll have to use two tools
launchctl You’ll have to start the job based on network availability. Unfortunately, this only checks to see if you’re connected to any network, not a specific one.
networksetup that gets the current SSID you’re attached to. The ...
The problem is the macOS continues to check for updates (including email, software, news, etc.) while your MacBook Pro is asleep (this feature is called "Power Nap"). This means it's very quick to get up and running when you open your MacBook, but it also means your battery goes down while it's asleep.
The problem some people have is that even with "Power ...
I see two possible problems here:
First possibility is that your MAC address after reboot is somehow invalid (i.e. for example set to all zeros). That could make your DHCP server (probably in your home router) reject your request for an IP address).
Check if that is the case by running the following command in the Terminal:
Note the line ...
There’s definitely a bug somewhere.
I’ve deleted the Time Warner profile, reset my iPhone X running iOS 13.3 network settings, and rebooted it several times.
When I click the info button for the secure TWC passpoint network, it does not show the usual auto-join, auto-login, or “Forget this Network” buttons.
My phone is still trying to connect everything ...
Try to solve it with:
resetting network settings
trying wifi networks with different settings
Resetting network settings:
Settings > General > Reset > Reset Network Settings
Trying wifi networks with different settings:
try to disable bluetooth, airdrop, and cellular data first (try to activate wifi while in airplane mode)
try wifi ...
I thought of two ways:
Check if any intranet webpage is reachable on the Mac. It wouldn't be, that confirms cellular data usage.
Check "What is my ip" on the iPhone once while using cellular, once using Wi-Fi. Then match those with the one on the Mac. It matches with cellular's. One can also use utilities listed in Allan's answer.
Regardless of how you connect to your iPhone acting a a personal hotspot, whether it be via WiFi or tethered via cable, you are sharing the cellular data connection.
So, using your example, where your iPhone is initially connected to the corporate WiFi and then you enable the Personal Hotspot feature, you will disconnect from the corporate WiFi and a ...
