Anniversary upgrade won't let me use my network!

Check the bios to make sure that it is enabled if onboard, along with if you are using WiFi, that the proper SSID is connected and the proper passphrase. Since Linux is stating that there is an issue, it is most likely going to be a Gateway problem. If it can connect via Ethernet and take you to say Yahoo.com, then you know that it is not a Gateway issue, unless you have hidden the SSID and made some changes.

Each OS will get a different IP assigned, even if it is the same MAC ID. It is just how the software for Gateways and IPTables is written.

Try running the homegroup widget. It will tell you if your network has been switched from Private to Public. When that happens, loss of access to LAN resources is typical. You may need to reset that...

Would Windows Upgrade change to bios? I am using WiFi.

No problem accessing the internet.

Yesterday I was able to access everything, today nothing except the internet.

No, but someone playing with the utility can change it through UEFI. It is always the first step when troubleshooting.

What username and password are you putting in it must be an account on the pc your connecting to not your pc username

That would have nothing with the device being disabled. They need to go and look to make sure that the adapters have not been disabled by going to Network Connections

All four of my computers have the same username and password.

And that would have nothing to do with your problem. Network Connections would show if that one machine has the adapters enabled or disabled. Same as if they are a part of the motherboard, you can check the Bios to make sure that they did not somehow get disabled in the bios. Pretty simple stuff.
