Any way to improve WiFi performance of Mac Studio M2 Ultra

Poorly shielded high speed USB cables, drives, devices and even displays can cause Wi-Fi interference.

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

As a test:

Disconnect any none essential USB devices and make sure that the essential ones are not in the line of sight between the Mac Studio and Wi-Fi router.

Sure ! See den.thed’s answer, but also wifi can be blocked by metal in walls which you can’t do much about.. i’d recommend a mesh wifi setup or some kind of wifi extender… i don’t have a mesh wifi setup, but i do have an Airport Time capsule as my main wifi, extended out to a newer version of an Airport time capsule which is in my living room. I live on one floor so my wifi needs aren’t super complex. What i have works fine… strong wifi signal all around my place … also consider switching to 5Ghz rather than 2.4 ( less interference on 5ghz) and picking a wifi channel not used by a lot of people. If you hold down “option” and click on Wifi icon at the top of your screen, you get detailed wireless info… including channel. Frequency and strength of your current wifi network… if you’re not using an airport, but instead your modem’s built in wifi, that modem might have a user setup menu… accessible by typing in a special IP address , then a special username and password, which might be on a sticker on the outside/bottom of the modem, as i don’t know the model and maker of your modem.. i think i’m done for now
