VodafoneStation needs restart every few hours

[Pindulfo1]

Hi,
Every few hours the internet connection suddenly starts failing (50%-100% packetloss).
Only solution (temporal) is to restart the Modem. 
This behaviour is happening since a few days now, periods getting shorter.

* Modem: leased VodafoneStation TG3442DE (3y old)
* Modem is in BridgeMode, yet same problem occurs when switching to Router mode.
* Internet & Phone 1000 Cable plan
* Region: Berlin
* Local LAN traffic is Ok. No packetloss, no bottlenecks.

Is it the modem starting to fail? or is this normal?

Following is an example of the frequency:

Hello Pindulfo1,

The technician needs access to the house distribution system and an information, whether there are persons in the household who are in quarantine. Please leave us also a phone number via PN, so that the colleagues can arrange an appointment with you.

Hello Pindulfo1,

in the PN you sent your customer data again and the phone number. What about the access to the house system and the question about Covid?

If you do not know where the house system is, then please ask the janitor.
