I have a desktop computer running Windows 10 that seems to be causing timed-out connections to all computers when it’s connected to the network.

When I have this computer connected (via ethernet) to my router, I find that internet frequently drops out for all computers. This is verified by a ping of Google started on my MacBook.


However, this affects my internet connection only, and doesn’t affect connections within my LAN. For example, even when Google is timed out, I can still transfer files fine between my MacBook and the Windows desktop.

The reason I suspect my internet troubles has to due with the Windows desktop is that when I disconnect the desktop from my network, the internet connection becomes very stable on all my other computers.

I just can’t figure why or how the Windows computer is affecting the internet not only for itself, but for all others on the network as well. Obviously, it can’t be as simple as something like an IP conflict, since that’d make the Windows desktop inaccessible to other machines on the LAN.

I already tried restarting all the computers, router, and modem in my home. I also tried getting a new router, since I suspected some sort of strange incompatibility between the Windows desktop and my Airport router. But alas, the new Netgear router shows the exact same issue.

Does the ip and route config change on the other machines when the troublemaker starts?

The IP conflict should be easy to check: print current IP on all devices.

My first guess would be you have a relatively limited internet speed and when you're connecting the Win 10 PC it's immediately slamming that connection trying to download updates.

This. Windows 10's Windows Update feature really SLAMS connections. Can't even listen to my 80-128Kbit/sec internet radio stream on my 15Mbit/sec connection, when one of my PCs goes to download updates.

My business unit at work is primarily dealing with small banks, frequently in remote areas. They want you to make a business case why they need to upgrade from a 1.5Mb T1 to a 3Mb. Windows 10 has been glorious in that regards, watching an executive buy a new laptop without consulting us and then effectively taking down their whole network. Turning off P2P updates is a necessity on limited bandwidth connections.

Can't you just have the Windows PC set to "metered connection"?
