Default gateway is not available (frequent)

[TriaChi]

New laptop, and since the beginning problems with wifi.

Every other device in my house works perfectly well with our wireless wifi.

But this laptop seems to have some trouble: every now and then, while browsing, the internet connection seems to get lost, although the icon in the right bottom corner shows no problems with the wifi. This happens randomly: sometimes a few times per day, sometimes every 5 minutes, and sometimes not at all.

When I run the built-in Windows Network troubleshooter or the Chrome extension HP Network Check, it always describes the same problem: "The default gateway is not available."

Tried potential solutions so far:
1) Run Windows Network troubleshooter or HP Network Check - it fixes the problem, but it comes back.

2) Uncheck the box for "Allow the computer to turn off this device to save power" - No impact on problem.

3) Update/Rollback/Delete (& Reboot pc) the following drivers: "Realtek RTL8822BE 802.1ac PCle Adapter" and "Realtek Gaming GbE Family Controller" - No impact on the problem.

4) Shut down & restart the WiFi driver "Realtek RTL8822BE 802.1ac PCle Adapter" - fixes the problem for a while but it comes back

What can I do to solve the problem permanenlty?

Thanks in advance.

Please open command prompt and type ipconfig then hit enter. You should see something similar to the following image

         

Note: the IPv4 Address and Default Gateway MUST have same first 3 ranges.

Same issue, and don't know waht trying else. 

Did you fix this problem? If yes, could you let me know the solution?

I've read somthing about the BIOS to be set up again, but I'm afraid to generate bigger problems...

I am also having this issue. Default gateway not available, tried the listed fixes with no effect. 

HP Spectre X360 - 13t-Ac000 CTO

A while back I found a temporary solution by changing network adapter drivers (the problem occurred less often) after applying this fix from Paul.

I recently updated drivers thinking the issue would get even better, but was wrong. I began losing connectivity every 20-60 minutes. Rolled back drivers to the ones suggested in the above referenced post but the issue is still happening much more frequently than it used to with the same drivers.  

If anyone has a solution I would very much appreciate it.  Thanks!
