Dear community.
Several weeks ago I paid attention that the internet speed from my Connection Box becomes very slow.
The “problem” can be solved be re-powering the connection box.
Here down are the speedtest examples before and after the re-power.
The test is done at raspberry pi 4 connected to the modem by the network cable.
WiFi at the modem is disabled.

My subscription is 300/30, so just after the reboot the connection box is working close to the allowed maximum.
But after some time the speed degrades.
OK, 5 Mbit/s is, frankly speaking, enough for the most light tasks, but I pay for 300 Mbit/s.
Am I the only one facing this problem?
It is very annoying to re-power the connection box, say, once a week.

Best regards, Dmitry
