My computers indicate an active Internet connection, but can't find a server.
This has been happening periodically for the last week.
My network is a desktop and two laptops all running Windows 10 Home. The cable connection from the wall goes to the modem which is wire connected to the router which is wire connected to the desktop. The two laptops connect wirelessly. The desktop can apparently do either a wired or wireless connection or both.
What has been happening is that any of the computers will start occasionally returning a server not found after clicking on a link. Reclicking or refreshing will typically connect to the server. But the problem gets progressively worse and worse until the computer can't connect at all ever though it appears Internet is available. This can be initiated from any of the computers and affects them all simultaneously.
When I contacted my cable provider we disconnect the cable connection and the power to both modem and router, waited a minute and then connected, cable first, modem power next and router power third and everything worked beautifully. My cable helper said it was just a glitch and nothing to worry about.
But this has now happened several more times with this fix always being effective but temporary.
Now the big question. Is the problem my cable connection, my modem, or my router? I just bought a new expensive router because mine is probably 10 years old but I haven't received it yet.
How can I tell if my modem is working well? Any advice would be welcomed.
