Internet disconnects ramdomly

My Z97 win 10 Pro fulling updated
The Internet has been disconnecting randomly or after a long period of the computer is idle.

This is happening on both my LAN NIC and My Wireless NIC. I am not losing Network connection
my network is 4 computer on a P2P network I can access the drives. i just can't connect through the internet "GO TO My PC" I work remotely and need this to work

I have ordered a new NIC LAN but last night I left it on wireless only and this morning I can not access the internet.
I will have to reboot to get it back.
Must be some setting got changed on one of the last WU or the Patch installed last week \

Yes network is still up only the internet is disconnecting.

In Device Manager, Network Adapters, right click it and select properties. See if you have a 'Power Management' tab. If you do, uncheck 'Allow the computer to turn off this device to save power' if you have it.



Or, if it looks like this uncheck energy efficient ethernet

Thanks I have unchecked allow the computer to turn off this device to save power. I get back to with results in tomorrow. Thanks for the Information I had missed this

New NIC card going in today

Ok, this issue is still giving me fits. it appears that about every 6 hours something turns my internet off on this one computer. This started happening about 2 weeks ago.
I put in a new Nic Intel 1210, the built-in 1218-V was apparently still working.
Broadcom 802.11AC working
When this happens it is only the internet that is being shut off and it does require a reboot to get the internet online again.
It happens with any of the three NIC I have on this desktop listed above.

My P2P network 3 desktops 1 notebook stay up. I am able to access drives and transfer file from this computer and the other 3 still have internet access.

So that isolates the problem to this computer only. the other three still have internet and network so that should eliminate a cable modem problem or an Asus AC1900 router problem.
I suspect the issue started with the KB4056892 update, I did install the KB4073290 update that did fix some other issues I was having. It took me a few days to notice this internet problem. I have images that I can restore from before those update but be going back that far world cause issues with my business.
I Have Sleep shut off using gpedit setting
I have hibernation shut off in advanced setting power options. All my computer are on good UPS so I would know it hibernation was taking place. which really doesn't matter since yesterday the internet shut off as I was online and using it.

So somewhere there has to be some setting that is telling my internet to turn off every 6 hours or so. Causing me to reboot the computer to regain internet access.

This one really has me frustrated as I need to access this computer remotely from time to time and I can not do this without it being on the internet.
