How can I fix internet speed issues on my Mac mini M2 Pro?

You're welcome.

It's your prerogative of course to not spend more time on the issue. Just a thought though--WiFi issues, for any device, can be time consuming to resolve. There's a lot of variables--hardware, software, location, the room/building, the weather, etc--and many/most aren't static in nature. It can be frustrating, especially so when a problem suddenly appears. It's not an uncommon irritant and is possible for any WiFi device/appliance.

(At some point if you end up troubleshooting the issue, you'll help yourself if you're systematic in your approach and write down each step you take.)

Troubleshooting Mac Wi-Fi:

Just because you have a network connected does not mean your are connected to the Internet. You may be using intenal LAN services.

Troubleshooting Mac WiFi:

A few thoughts to try...

I. Clear the Temporary Internet Files:

• Cookies perform remembrance of certain site-entered data.
• Cache keeps a snapshot of the last time you visited a site.
• Go Here: Clear your browsing history in Safari on Mac - Apple Support

II. Restart your Router:

1. Power: off the router
2. Wait: 30 seconds
3. Power: It back on

III. Boot in Safe Mode:

In Safe Mode, Login Items do not run at login, certain preferences are set aside, and damaged system files are then reset. So, once booted in to Safe Mode, wait 30 seconds, and then boot up normally, attempting another update install. For instructions, go here: How to Use safe Mode on your Mac - Apple Support

IV. Try a New Admin User:

What happens when you create a new administrator user, and log into it? Do you still get this error? If not, then it is likely an error with the current user. If so, then it is likely an error with your Mac.

Price has no relation to "perfect". You could buy a Rolls Royce and still get a lemon.

I have the same model mini you do and have no issues with Internet access. But for full disclosure, I have also never used WiFi with it. I'm just a few feet from our Xfinity router, so I use a wired connection.

High speed USB cables, drives, displays and other devices can interfere with Wi-Fi and Bluetooth.

see > Resolve Wi-Fi and Bluetooth issues caused by wireless interference - Apple Support

1) Check to make sure that there are no USB cables or devices in-between the Mac mini and Router.

2) If possible, move the Mac mini and Router closer together and/or use an Ethernet cable.

3) Test the Mac mini on its side with bottom facing the Router to see if Wi-Fi improves.

If you've not and if you're able to, try separating the bands (ie, 2.4 GHz, 5 GHz) in your router. Router band auto-connection/switching can be finicky. Forget the network in your Mini, and other devices, then reestablish connection with the router's new configuration. Test each band to find which one, if any, gives you joy.

If you've not, check your router's manual/documentation for its QoS (Quality of Service) implementation and settings.

There's also channel width to consider. Apple suggests:

"Channel width

Set to 20 MHz for the 2.4 GHz band. Set to Auto or all widths for the 5 GHz and 6 GHz bands.

Channel width specifies how large of a “pipe” is available to transfer data. Wider channels are faster but more susceptible to interference and more likely to interfere with other devices.

20 MHz for the 2.4 GHz band helps to avoid performance and reliability issues, especially near other Wi-Fi networks and 2.4 GHz devices, including Bluetooth devices.

Auto or all channel widths for 5 GHz and 6 GHz bands ensures the best performance and compatibility with all devices. Wireless interference is less of a concern in these bands."

Might try this if it slows again...

You can try it manually in a terminal window: sudo ifconfig awdl0 down

To reverse the command, type: sudo ifconfig awdl0 up
