Your computer adapter will not connect to the internet: It's a driver problem, not your router

A recent Windows update has left many computers in a state where the computer can no longer get an IP address from the router; so you can't get on the internet.  The short of it is that a Windows or driver update, not 100% sure which but suspect the Windows update, has busted your driver.  You can't just update the driver.  The quickest way to fix the problem is to go into Device Manager.  https://www.lifewire.com/how-to-open-device-manager-2626075 https://www.lifewire.com/how-to-open-device-manager-2626075 , find the Network Adapters entries, click to open all entries by clicking on the > in front of Network Adapters, and left clicking on the ethernet or wifi adapter that you are using.  Click on "Uninstall".  Restart your computer.  Should be fixed!   If not, let me know in the comments, along with the name of the adapter.
