If you're seeing it prior to M4 that seems strange, unless the kernel/ath11k is doing some odd queuing? > yeah... firmware has some odd assumption on the sequence of key install, causing such behavior. > Do you think maybe this has something to do with it? Its just a timing issue (both in my case and when you see it before M4) and in some cases the keys aren't fully installed and the request either gets dropped or just isn't encrypted correctly? Like I said originally, its not like this issue is severe, we can just request a neighbor report later and that does work. It was just an observation and didn't seem right. Thanks, James
