Router keeps restarting

[#1]

Hi, I have a problem with my Internet. I use plus net for a year and everything been ok. But all last week I can't do anything cause my router keep restarting every hour. I tried reconnect and manually restart it, didn't help. What should I do?

Have you got a Google Home device? If not then your router may have developed a fault, contact PlusNet and they may replace it for free (possibly have to re-contract).

Hi there, could you describe in more detail what happens when the router restarts? 

I don't want us to overlook a possible fault in case the router isn't the problem.
