Question Could a home router work or fail only partly?

[brannsiu]

I have subscribed to the current ISP service for up to 10 years and its home broadband connection had been very stable for a long time until recently. Now, it almost disconnects from the web by itself a few times a day and I have to unplug the power of the router, wait for a few seconds, and then plug it in again, then it will connect to the web again.

I see someone say it could be the failure of my router. However, could a router just fail partly like this? Is it likely to be the problem of ISP side or my side?

Have you interfaced with the ISP on this?
Is this an ISP supplied device?

It is Netgear router which wasn't provided by the ISP. It's supposed to be direct broadband that only a lan cable is enough. The router is used to provide WiFi for other home devices.
