I have an issue that I noticed recently, but I don’t know whether it came with beta 2 or was already happening when/after I installed the first alpha of 3006 (for my GT-AX6000) and made a change to my network setup.
Because we now have better “guest” networks I decided to make my main network WPA3-only and set up an extra network for just my Apple TV HD, which does not support WPA3. However, since doing that, wireless transfers from my MacBook Air M1 to that Apple TV are extremely slow (it takes close to an hour to transfer 2 GB).
I have not noticed any other network slowness. What could be wrong? What are good steps to investigate this?
