Title: No Internet Connection
Post by: NetConnectThrowaway on January 16, 2018, 04:50:02 AM

I have no internet connection my Windows 10 desktop PC and it's not due to my router. It's connected via Ethernet and has been tested on someone else's network and has the same problem. Here's some symptoms:

Windows Network Diagnostics tell me my "Ethernet" doesn't have a valid IP configuration and it cannot fix this.

ipconfig /renew does not work as shown below with my ipconfig /all

Code: [Select]

An error occurred while renewing interface Ethernet 2 : unable to contact your DHCP server. Request has timed out.
No operation can be performed on Bluetooth Network Connection while it has its media disconnected.

Enabling/disabling/uninstalling my Ethernet driver via device manager used to fix the problem sometimes, but it does not fix the problem anymore. I can not install newer drivers from Intel because "The installed version of Intel(R) Network Connections is not supported for upgrades. You must uninstall it before installing this version." even though it was already uninstalled.

I've tried a few more fixes, like other command lines and trying other Ethernet cables, but they don't seem to help. I've tried every fix from here: https://support.microsoft.com/en-us/help/10741/windows-10-fix-network-connection-issues

If you have any clue of what's going on, please let me know! Thanks for your time.
