Poor Wi-Fi Reception on Mac 2025

My New Mac studio 2025 has abnormally weak Wi-Fi reception

compared to an older Mac mini (2012 ) tested in the same location under

identical conditions. I’ve ruled out software and network issues by.


sudo rm /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist
sudo reboot


don' t work.


Why ?


Thanks

Mac Studio (M4 Max, 2025)

Wi- Fi Radio Signals from your router fall off as the cube of the distance if you have clear line of sight and no competition from neighbors' Routers or known interference producers like microwave ovens.


All others need to do a more careful analysis to find out what is happening.


Wireless diagnostics:


Hold down the Option key while you click on the Wi-Fi icon on the menubar to open up the tools for investigating and fixing Wi-Fi issues


First is "Open Wireless diagnostics", which opens the wireless diagnostics Assistant, but does not proceed.


There are about eight different things you can do from here, but the top-level is to choose Diagnostics off the Window menu, or simply click continue, to do a quick check for Gross misconfiguration or operating problems. Your Admin password will be required. If any recommendations are shown, you should consider then seriously.


Next is to hold down the Option key and click the Wi-Fi icon as before. The screen that opens shows operating parameters of your network. Screenshot, transcribe, or photograph the results and post back in a reply on the forums. Looks like this older one.
