I think you might have responded to the wrong topic.
How does seeing errors in the log and having configurations resetting have anything to do with a browser cache?
Again, two issues:
1) Configuration resets itself (often after a long period of hanging during power startup).
2) We see frequent "'Disconnecting (deauth) wireless client: ffffffffffff (Reason3)" messages in the logs (which continue to occur, and we're able to log into the device (etc, etc, etc).
Can you help?
