this new firmware is even worse than the out-of-the-box 2.01EU one from early june. active long-duration tcp connections like IMAP or IRC get disconnected after exact(!!) 500 seconds, regardless of being connected via lan or wifi.
in addition to that, the new firmware build also shows the same symptoms as the old one: after a supposedly random usage time of 1 to 24hr, the 825 wifi begins dropping tcp packets, resulting in up to 90% (!!) packet loss. only a reconnect immediatelly but only temporarily "fixes" the problem.
my dir-825 experience so far is one huge disappointment.
