I'm going to try and be as descriptive as I can but it started out when I was going to update the driver for killer network manager and I downloaded the new driver and went to install it uninstall the old driver and while installing the new one it said it failed and then and never connect me back to the Internet I tried finding the old driver and tried multiple other ones but nothing will seem to work to get me back on the Internet.
I seriously been at it for about 7 hours straight doing multiple things. I made sure my network card is enabled in the BIOS and everything.
Windows says the drivers installed but when I go to view driver it says its not installed and then when I troubleshoot the issue using Windows find the driver and reinstalled it but doesn't help any.
I've also tried resetting the computer multiple times along with turning it completely off and taking the battery out of the motherboard and letting it reset completely to no avail. Sadly I don't have any restore points or recovery points to go back in time and reload my computer before this happened.
Please if anyone has any tips I went to every website all over the internet trying to find answers basically my computer is completely useless I can't get on the internet at all no matter what I do.
