Hello Stephane,
thank you for your mail.
A colleague of mine reported me today some additional informations.
This case is the same with the outage form the internet every 2 hours.
The modem was updated to the version 140829c on the 27th November and on this
Weekend the problems has started in his home network.
He is running different devices on his network like Loxone(home automation server)
Some devices and some raspberries for MRTG and so on.
On Friday it started, that the internal gateway isn´t reachable. The communication
Between the devices on the modem-switch are worked, but the gateway wasn´t reachable.
After a few minutes the devices are working like they should and internet was working.
When the next problem occurred he stared a dump on the local side to see what´s the problem
Is in this case. He see that at the end of the outage the cablemodem sends a lot of arp
requests (Who is) and the internetconnectivity is working again.
In the case of the problem he also tried to set static ip-addresses at the devices, but the connectivity
Doesn´t worked. And he has also configured the gateway address by the mac-adress on the device to
Check the connection, but nothing has fixed the problem.
The modem itself was working normal all the time. it seems, that the problem is located only on
The internal side of the router.
After a factory default the problem was gone. Until now the problem didn´t occurred again.
He has called me after the factory default and so I was not able to see any things on the
Modem like logfiles and so on.
