Wi-Fi slow on Mac Sonoma

I'm wondering why my iMac running Sonoma is so slow on Wi-Fi. My MacBook Air and both of my iPhones show speeds of 300 MB per second my iMac shows only about 75 to 100 MB per second.



iMac 21.5″, macOS 14.0

Are you running any VPN, Anti-Virus, or Cleaning apps?


We need to see what all is running, a report from this will not display any personal info...

Hi!


Here to help.


I need more information

Did you use speedcheck? Is that up- and download -speed? (https://www.speedcheck.org/ > third party website!)

Do you have latency when opening webpages?

Do you experience disconnects?

Have you tried a different wi-fi network?

You could also try adding a test user to see if it is user-account-related (apps, VPN, Blockers etc).


Personally, I don't think the operating system (MacOS Sonoma) is the source - usually it is

  • VPN, Antivirus, "Snitch, Clean my Mac"
  • Cookies settings in browser, history full / webdata full


Let me know if above tips & tricks get you any further!


Kind regards

RRD

I have an iPhone, an iPad mini and a ten year old MacBook Pro all running over 200mbps on download speed test. My brand new MacBook Pro can barely achieve 50. I'm questioning why I bought this equipment as it simply doesn't work. Interestingly, even when hard wired using a Cat 6 it is still only 25% of the speed of the other equipment.

It looks nice, good battery life but pretty hopeless as a computer. Any thoughts from anyone? I don't know how to contact APPLE, tried numerous times but just get referred to these community links which I feel is a lousy way of getting free labour. Thank you.
