Chosen Solution
I have the similar sub par wifi problem in my Mac Studio. Lifting up Mac Studio doesn’t help at all. I found that it performs faster if I use 15 year old tech 802.11 n. I can get 29Mbit/sec. If I used 802.11 x at 5Ghz, I could only get 8Mbit/sec. At the exact same spot, my 2013 MacBook Air connect through 802.11 ac at 5Ghz, I could get 101Mbit/sec. Note that the another end in iperf3 is my Dell T20 connecting through ethernet -> switch -> Unify U6-LR. Here is screenshot. My Mac Studio wifi is horrible. I sent a complaint to https://www.apple.com/feedback/mac-studi… I booked an appointment today in Apple Store and see what the solution genus can provide. If not, I will just return it. This is Mac Studio at 802.11 ax 5Ghz
This is Mac Studio at 802.11 n 2.5Ghz ++
++ This is 2013 MacBook Air at 802.11 ac 5Ghz ++

@rickyzhang My Studio is normally wired but I just did a test and it runs on WiFi6 only at the limit of my connection speed (1GB). I’m wondering if there’s some nearby interference on your 802.11ax channel. Before you trudge off to the “Genius” at the Apple store have you tried moving the Studio to a different location in your workspace? Have you tried a different channel for 802.11ax?
Plug the RJ 45 into it straight from the router, wifi in alot of Macs is “subpar” i have circumnavigated Apples wifi this way for years. NO MORE WIFI WORRIES!
