Well yes and no, is the router disconnecting or just restarting? If it's restarting the NAS your session is connected to will wait a while for the session to timeout. Which is why it isn't able to reconnect immediately.
I will extract the data and escalate with your line provider removing the drops at 7am.
The reboot cuts power to the NIC ports which will cause the CPE/ONT Ethernet to do into a disconnected state.
If the NAS is still live on your end, then this is a simple fix? Time Out should not be set for over 60 seconds?
If it took a couple of minutes I understand but it takes hours at times!
When the router requests a reconnect/dial up; the NAS connection should reconnect?
This also does not explain why the line functions at 10Mb when it does reconnect after a reboot instead of 25Mb.
I appreciate the help you have provided me in the past and that you still do now however this issues have been underlying and pointing to a Line issue for a long time and not being resolved.
Also, the people manning the help desk should keep clients updated daily to avoid frustration.
They should also read the ticket, see what testing has already been done; read what the client has confirmed he/she has done and then ask them to do more tests.
MTR Tests done, Trace Routes done, CPE/ONT info with photos handed over on the 27th with a response only on the 30th with no feedback until I followed up a couple of days later.
I then send a speedtest showing high latency and lower than 10Mb line speed and informed its my WiFi; I am sure the person that replied did not read the whole ticket!
I then did a speedtest on the LAN using my Xbox which showed even higher latency.
The next day I have no internet at all and eventually it starts to work again in the afternoon at which point its working at 25Mb and not 25Mb.
This morning I got 25Mb down but only 5Mb up. I did not log this as I sent 8 messages that has not been responded to on the help desk.
Rant over for now. Lets hope it does not stop working again tonight.
