A "very..." long shot...

Have you simply rebooted the router (full power down and remove power for about2 minutes); or even reset it to as delivered and then reconfigured it?

> browser shows "No Internet".

Everything about my setup is different from yours, but when I connect
to the Internet, the Networking thingy that pops up out of the "System
tray" at the right end of the Taskbar (same as the Network button in
the Action Center) usually says "No Internet" when the connection is
complete, and I know I can go ahead and do stuff. Sometimes it has
the name of my WiFi hotspot when it has finished connecting, but more
often it says "No Internet". That's the way this wireless modem/router
has always worked.

For some reason you are not getting a DHCP lease from the router. I take it that other devices on the network get addresses OK?

Two things to try - to at least isolate the problem.

1. Try connecting the device directly to the router, bypassing the switch. (I relize that's not a long-term solution, but it tests whether the switch is the problem).

2. Power cycle (switch off and on) everything - device, switch, router. Leave each off for five minutes or so before powering up again.

Let us know if either of these affects the situation.

Is the LAN cable OK? Have you changed with a known good one?
Are the LAN LEDS (if present) flashing on switch and PC?

Set a static IP address (same range as your router) and try to ping router or other connected devices.

Don't know if it would help but you could try an IP release & renew.

Press the Win key and the R key, type in
cmd
and hit Enter
In the command prompt window, type
ipconfig /release
and hit Enter
Then type
ipconfig /renew
Press the Enter key again.
Type
ipconfig
one more time and see what address it gives you.

It resolved automatically. All devices switch, router, PC and all cables are working fine now. I did not replace anything. I don't know what happened. It took 2-3 days, I think.
Now which answer should I select as a best?
Thank you everyone.

It happened again today. I disabled and then enabled. It didn't work.
BUT after some time, it is working fine.
What to do?

@THX 1138 I have not tried your tip. I will try it next time.
