Thanks!

mikloshumli,

Do you utilize any third-party software or VPNs? These can also affect Wi-Fi performance especially since it's fine after first turning it on. Even though your other Apple devices work fine, double check the settings to your router as well which might also affect it, especially if you use per-device settings of any kind: Recommended settings for Wi-Fi routers and access points

Take care.

Judging from your screen shot >>

The computer is in fact using some type of Third Party Security Software

Which is unless, causes issue including what the machine is experiencing now - Intermittent Fast then Slow Internet Speeds

Any Third Party Applications that will interfere with the normal operation of the OS,  is an invitation for disaster and comprise the Operating System

Certain Applications maybe available on the Apple Apps Store - this only means the Developer is prepared to pay Apple a portion on each sale. What the Application may do to the computer is up to the User to check this out before purchase

Any of the below should be removed as per Developers Instructions 

This will include CleanMyMac , This will include BitDefender , 

This will included Norton Antivirus , Sophos Av Software

Intego AntiVirus, McAfee, MacKeeper, Avast AntiVirus

Ad Guard, Webroot , ESET , Avira , Dr Cleaner Pro Plus

AVG AntiVirus   avira antivirus

Read some of the posting and arrive at your own conclusions.

It might work correctly if you use the same method as I did.

When I was in the same situation, I went through a lot of trial and error. Here is what I found out.

1. turn off Bluetooth and Airdrop.

2. Set the SSID displayed in the "Networks I have connected to" column for the following picture to one.

You said;

The ipad and iphone, on the other hand, use the same Wi-Fi as the Mac Studio

How old are the pad and the phone ? These devices could be causing the Wi-Fi network speed to throttle when connected

Try disconnecting the iPad and iPhone from Wi-Fi and try again

Try connecting a Ethernet port from router directly to Studio (I recommend)

Know what your ISP download and upload speeds are.

If the advertised speed is close to or lower than half the advertised rate for days, that’s the time to call your ISP, but ONLY if you’ve already tried above first. The ISP will ask before continuing, good luck
