I'm using 3.54b and patch 3.0 on an adsl line with a devolo microlink router, portforwarding is set up as it should and this configuration works fine for nearly half a year without any changes.
The last 24 hours i lost my connection about 20 or 30 times. While that happened, there were active downloads and uploads which haven't been affected at all. At the beginning my queue fills up rather fast to an average of 100 users. The files in my transfer-window aren't rare so i get remotely queued at about 50 to 100 users by the same time. Some minutes later this begins to reverse, leaving me with my active downloads only, while all other connections drop one by one.
This happened about 30 times in the last 24 hours and i haven't got a clue what's going on.
