New Dell PC crashes network

Hi,
Whenever I connect the Ethernet cable to my new Dell PC (Inspiron 3655, win 10, 64 bit), traffic goes up to about 50% without any application open and effectively crashes my home network (3 PCs). When I disconnect, everything goes back to normal.
I have installed Glasswire Network Security and it turns out that a content provider (Akamai.net) hogs my bandwidth. Apparently it corresponds with one or more of the many MS apps that are installed in win 10.
Can someone help me to indentify those apps so I can delete them and get rid of that annoying traffic?
Thanks,
Ed

I have no idea what bro67 is saying!
Glasswire does not kill the network, it just shows the traffic. Someone is hogging my traffic.

Akamai.net servers are where Windows Updates come from. Your PCs are being checking and receiving updates.

Shouldn't I see the downloads when I look at Settings -> Updates?
When I check that it says that my PC is up to date and there's no downloading.
However, Glasswire shows over 50% usage and my network is at a standstill.

Did you remove the Dell crapware on your new Dell? Also, don't always believe that everything is up to date.

Disable glassware and use the Task manager Performance tab Network and see how much network activity is happening.

At present the network traffic is down to normal, go figure.
But you're right, there are several Dell apps installed.
Which ones can safely be uninstalled?

Personally I remove all Dell software, but I always do a clean install on a new computer.
