NetworkManager: <info> Activation (wlan0/wireless): asking for new secrets
Sometime, very occasionally, it will authenticate and then it seems to stay authenticated. I'm sat about 6 feet from the AP aerial so I get something like 97% signal strength according to nm-tool. But, this looks a little strange as they seem to be the same MAC (unless I'm misunderstanding what the output of nm-tool gives)
This seems to be a timing thing.
I'm having the same problem and my log lists

I sometimes had this issue with 8.04 as well but the 8.10 RC seems to be worse.
