Newly purchased (February 2024) Mac Studio has very slow wifi speeds at times and often drops out completely. The computer is sitting beside an old 2009 Mac Pro and a Windows machine on the same network, neither of which experience this problem, so that pretty much rules out the router. Any suggestions?

Why do I have difficulty with Wi-Fi or Bluetooth devices when USB 3 devices are attached to my computer?
Some USB 3 devices can generate radio frequency interference that can cause Wi-Fi and Bluetooth devices operating in the 2.4GHz band to have issues communicating with your computer. Here are some tips to avoid this issue:
• If your USB device has a cable long enough that you can move the device, place it away from your Mac—and make sure not to place it behind your Mac, or near the hinge of its display. The antennas for Wi-Fi and Bluetooth are located there, and USB 3 devices placed there might interfere with your wireless connections.
• If you're using adapters or dongles on a Mac computer with Thunderbolt 3 (USB-C) ports, plug them into the front port on the left side of your Mac, or into the ports on the right side (if your computer has them). These ports are the farthest away from the antennas, making interference less likely.
• To avoid interference on the 2.4GHz band using Wi-Fi, try using the 5GHz band instead. You can change this on your wireless base station. Bluetooth always uses 2.4GHz, so this alternative isn't available for Bluetooth.

there may be additional issues, possibly even more severe:
• LG-display recall -- to address Wi-Fi interference so severe, it knocks the Router off the air if too near the Router.

The router itself is rarely the source these problems.
Hold down the Option key while you click on the Wi-Fi Icon on the menubar. You get a snapshot of current parameters. Screenshot, photograph, or transcribe your results and post back here for analysis:

Problem solved! I was using a Satechi stand/hub for an external SSD which was positioned under the Mac Studio as per the design. This was obviously interfering with the signal from the router since, as I understand, the antenna is in the bottom part of the computer. Removing the stand/hub to another position (on top of the computer) resulted in speeds in excess of 150Mbps and no dropouts so far.
