my Macbook pro (m1 Chip) disconnects wifi when mirroring

[halleaspen]

I only see an entry on this subject from several years ago.  Whenever I mirror (through Apple TV) with my tv my MacBook Pro disconnects wifi.  It is not one network, it just does not allow for any wifi use.  I had no trouble with my old MacBook or with my phone.

Is there a reason for this?

"Certain displays can emit harmonic interference, especially in the 2.4GHz band between channels 11 and 14. This interference might be stronger if you're using a notebook computer with the lid closed and have an external monitor connected. Try changing your access point to use 5 GHz or a lower 2.4 GHz channel."
