[atlas] Probe disconnects every 2 hours

Hello,

the logs for my probe (version 1) show that is has been disconnecting
very regularly every 2 hours. The uptimes are always +/- 1 hour 50
minutes, followed by a disconnect period of 5, 8, or 11 minutes.

Out of my last 25 connects, 20 are like that. 3 have double the uptime
(about 3 hours and 50 minutes), only one has almost 24 hours, and the
current one is 6 hours and counting. The disconnects there were, again,
5, 8, or 11 minutes.

However, I to not notice similar disconnects as a user of the same
network. I sometimes listen to online streams for more then 2 hours
without interruption. I work on my computer for more than 2 hours and
don't notice these interruptions of my internet access.

It's all IPv4; no IPv6 here. The controller is ctr-fnc01.

What could be the cause of these log entries?
