Does wifi work on 5GHz or only 2.4GHz?
I wasn’t able to get my MK4 wifi to connect to my 5GHz wifi network but it works on the 2.4GHz network. Is it supposed to work with 5GHz wifi?
RE: Does wifi work on 5GHz or only 2.4GHz?
I don't own a MK4 but my uneducated guess is that it won’t. That’s based on personal experience because, even if my router works with both 2.4 and 5GHz bands, of the devices that I connect to the network, only my Xiaomi phone supports 5GHz. My two Canon printers, mini computer, Sony camera and Voron 3D printer will connect only at 2.4GHz, so I expect that Prusa’s very-slow-wifi won’t support 5GHz either I can be wrong of course. Let's see what other MK4 users can say about this.

I believe it uses an ESP32-WROOM-32 module, which does not support 5 Ghz.

2.4 only - but it's so slow it's borderline useless (same with eth) so plan on either USB or Octoprint.

I did not look under the cover of mine when it was still outside the enclosure, but from what I see in the photo in this article, it is an ESP-01S, which uses an ESP8266. Boards with ESP32 can support a live camera stream over Wi-Fi, e.g. the ESP32-CAM boards. Those should be a lot faster.

Yes, WiFi speed is painful. It's a bit better with the latest firmware but still embarrassing. Ethernet is in my hands about 3x faster and doable.

The wifi module plugs in - so maybe there is a faster module that may be available in the future?

Probably Raspberry Pis for Octoprint will be cheap again before that, I think. 🙂
RE:
depends where the bottleneck is.. If it is in the wifi module, or further down in the architecture..

No way while MK4 will use the ESP8266 (that is 2.4GHz), and an even slower SERIAL communication between the board and the ESP8266...
