Hi, i'm trying to troubleshoot why my home pc only gets 80Mbps on our 800Mbps internet connection. We have other devices, Roku, other desktop, 2 tablets, nintendo switch, and a couple of smartphones, and camera system also plugged in. I'm trying to figure out what causes my bad connection. Is there a home network monitoring tool you all recommend or that is most popular. Something open source or low cost?
Who is your ISP? What service connection is being provided: coax, DSL, fiber?
What make and model modem, router, or modem/router (if combined)?
If you have admin access to those devices you can learn a great deal about your network. Routers often provide some sort of listing or even a diagram/map of connected devices.
You can run "ipconfig /all" (without quotes) via the Command Prompt to obtain specific configuration information for each connected computer.
You can use "arp -a" as well to learn more about the network devices that each computer may be communicating with.
My recommendation is to start with a simple network diagram showing all known network devices. The diagram does not need to be a work of art or unduly complicated.
I counted 8 devices but you mentioned camera's as well. Any IoT devices that need to be included?
Just show the devices, label them with as much as you know about each device and how the various devices are physically connected or indicate a wireless connection.
Device name, MAC, IP address, etc.. Include patch panels, wall jacks, etc. as may be part of the network. Could be some bad or loose connection somewhere. How far apart are the devices. What is between the network router and the wireless devices? Walls, appliances, different floor levels, etc.?
Go online and look for example "home network diagrams".
