I read many reports here during the last months about "Wifi connection problems".
I find it very difficult to compare the different problems or even to say whether there are real problems in a single case.
1. As you said, wscreate, often it is not mentioned, which band is used.
2. Mostly there are no remarks on the area: rural, suburban, ...?
3. Mostly there are no comments on the question, whether a Wifi analyzer app was used to identify any "Wifi pollution" or whether a change of the Wifi channel was tried and with which success.
4. The flight situation in which problems arised was seldom mentioned.
5. The kind of problem is not always clear or identified: was it only the message "stronge interference" on the HUD? Was it a short loss of the video stream? Was the drone always controlable or not? Did the drone Auto-RTH?
6. ... (some more)
So here are many emotional discussions on this theme, but often very few or confusing information. In addition there are many comments like "that also exactly happend to me", but I sometimes find the described cases not comparable.
