wn3000RPv3 keeps disconnecting and taking rest of internet with it?

"

Maybe go to your router's attached device list, and write down the IP address of the extender, along with the LAN address of the router (generally 192.168.0.1 or 192.168.1.1).

Then wait for it to happen again.  First try going into your PC browser, and enter http://extender-ip-address (using the real extender ip address) and see if you get to the wifi extender's web page.  If that works, try to get to your router's web page (again using the IP address). yes

If both of those work, then try http://mywifiext.net and see if that brings you to the extender's web page.

The idea here is to see if you are losing both local and internet connectivity, or only internet connectivity."

Yes both of them worked, when my internet went down again I was successfully able to login into the router, into the Wifi Extender, and was also able to access the extender's web page.....

What on earth does this mean...

It suggests that the issue is with the internet connection (the connection from the gateway to the internet) - not the router wifi or extender, since you can reach both of their web pages.  What's puzzling is that turning off the extender seems to fix it.

Next time you might try ping 8.8.8.8 (either from Windows command box or the PS4 if it lets you).  That's the IP address of Google's public DNS server.  Pinging the numeric IP address checks the internet connection w/o using a DNS server (which was giving you those timeout errors in the browser window).  If that works, try ping google.com which will add DNS.

Pinging 8.8.8.8 with 32 bytes of data
Request timed out.
Request timed out.
Request timed out.
Request timed out.

That was generated whenever the internet was down and I pinged from cmd. 

Pinging google.com also did not work:

Ping request could not find host google.com. Please check the name and try again.

When I turned off the Wifi Extender, and then pinged from the PS4 I pinged successfully.

So this is what I think we know:

When the internet connection drops:

• you can still reach both the router and extender over the local wifi network
• The ping 8.8.8.8 failure confirms that the internet can't be reached.
• The internet can't be reached on either extender wifi or the router wifi
• turning off the WN3000rpv3 restores the internet connection on the router wifi.

Do you agree?  

This is a confusing combination of symptoms.  Here's one more experiment:  The next time it fails, leave the extender on, and instead power-cycle the router (turning it off and on), and wait for it to boot up and it's LEDs to settle down to their usual state.  See if that also re-establishes the internet connection.  Check the internet connection on both the router wifi and the extender wifi.

Ok.

So I did what you said, power cycled the router and left the Extender on.

No change at all, the internet was still inaccessible. When I pinged 8.8.8.8 and google, no luck with either.

The weird thing...I was unable to access either the Router OR the Wifi Extender ip addresses!

Thanks (though I wasn't expecting that result).

One more test that that might be useful.  That is to disconnect the PC ethernet cable when the problem occurs, and see if the PS4 can then reach the internet.

I am wondering if all this might be a result of some malware on the PC congesting your network.  So perhaps download malwarebytes, and do a full scan. https://www.malwarebytes.com/  The free version is enough for this, though of course you could take the free premium trial.

Hi,

Did what you said tried to access internet via the PS4 with the Ethernet cable disconnected from the PC, unable to get/form connection.

Have also tried a different Wifi Extender model....getting exactly same issue :(

Which says it's not the extender, it has to be something else.  I'm thinking the PC is the most likely cause.  Did you try running the malware scan on the PC?  

Yes I did, some issues were detected, I removed them all, ran several other scans after that, still the issue persists...

I have reinstalled Windows 10.

Hopefully that helps...

I hope so too.
