The canon wireless flash systems since about 2020 have had a problem maintaining connection because of the widening wifi band. I recall when I first got the 600RF\'s in 2012 they ere flawless, then suddenly they started losing connections, necessitating a power cycle on the flash themselves, limiting their service as a remote and reliable flash.
I recall Profoto revamped their entire \"air\" remote systems at around this time, while canon\'s introduction of the EF1 never fixed this problem. While a changing wifi landscape can;t be helped, canon could have circumvented this any allowing the flash heads to have a selectable interval where they reset their communications that forced (in effect what happened when you power cycle them) to re-establish connection.
Curious if folks here have experienced the same?
