Capture was made with Intel AX200. I tried all the checkboxes in the 802.11 Radio panel. None caused the timeline to show up.

It requires linear increasing hardware timestamps (there are some bugs in the capture hardware for both BCM and QCA and sometimes the hardware timestamp has errors). If it’s a QCA capture the timestamp marks the end of the frame, not the start of the data field, there is a checkbox in the preferences to account for that.
