Hello, I just wanted to provide an update on this situation. I was just contacted by Apple Feedback to try out 26.3 beta 3. I installed the Beta, and I was then able to change channels while capturing, which is great!! I still had a really hard time getting the capture started, but was able to get it working at times. I reported the details back on that. On a separate note, there is a SEPARATE issue with the new wireless card where networks that are not WiFi 7 don't report spatial streams or MCS rates. Any network that is Wi-Fi 7 does report this data. I filed this under issue FB22596601, and it is a "big deal" from a wireless perspective. Thank you, Bill Bushong
