what are you pinging?  it sounds like you are losing your default gateway, and cannot route,  are you pining the next hop IP or something else on the internet, try ping next hop IP if you are pinging something else.  you can also use traceroute to figure this out. traceroute to 8.8.8.8 or something like that.

The IP address which is returning destination unreachable is pingable. Trace Route is returning host unreachable. What exactly is causing this issue ?

Using WireShark it lists the same IP numerous times with the info.

Code Select Expand

Destination unreachable (Host unreachable) with protocol ICMP ?

Therefore, it's finding out what is causing this IP which I'm familiar with, to fail ?

can you provide a network diagram so we all know how this is all setup

is this wired or wireless network?  if wireless there may be contention from another radio nearby.
is this a PC or Laptop? If laptop is it possible that the NIC may be going to sleep.

is your modem possible loosing it IP and default gateway.

I'd suggest to also load up Wireshark and capture some packets to troubleshoot what is going on.

What method would you preview to provide a network diagram ?
This is a wired network. How should I save the information from wireshark, or simply just a screen capture ?
The internet connection is Fiber.

Recently as in the past few weeks, my internet connection on a computer will just randomly stop. Upon restarting the computer, although usually twice the internet will work again; but only for a short while before it stops working. The internet icon in Windows11 displays the internet connection as working but not any browser ?
