Windows 10 upgrade killed wifi
I upgraded to Windows 10 from Windows 7 last night on my laptop. The laptop is a Lenovo Z570 with an i7 processor.
My basic problem is that I do not have the capability to turn on my wifi and search for networks now. The hardware switch does nothing. I went into device manager and the network adapter is recognized and shows as working and enabled. The networking adapter I have for wireless is the Intel(R) Centrino(R) Wireless-N 1000. In the system tray, I only show the red "x" over the wired networking icon, no wireless options.
If I dig deep into the device manager, open the network adapter, go into events and click "view all events", there are several instances of the same error. They all list the same except for the driver name:
Device PCI\VEN_8086&DEV_0084&SUBSYS_13158086&REV_00\4&23872eb&08&00E1 had a problem strating.
Driver Name: oem6.inf ***or*** netwsw00.inf
Class Guide: {4d36e972-e325-11ce-bfc1-08002be10318}
Service: NETwNs64
Lower Filters:
Upper Filters: vwifibus
Problem: 0x15
Status: 0x0
Log Name: Microsoft-Windows-Kernel-PnP/Device Configuration
Source: Kernel-PnP
Event ID: 411
I also ran an intel Manual Diagnostics Tool and the Hardware Test failed with a result of "Wireless Hardware is not bound to transport driver"
Now here are the things I have tried:
1. installed multiple different drivers for the network adapter card from both Lenovo and Intel. - No change
2. uninstalled Kaspersky (read another thread that listed Kaspersky as causing multiple problems with an upgrade) - No change
I have not hooked up to a wired connection yet as I do not have access to the room where the wired connections are due to the fact that we have a visitor staying in our guest bedroom.
I have a lot of work on this computer and would rather not do a clean install if there is a way around it. If it comes down to that, I will do it, but I would rather not if at all possible.
Thanks in advance for your help!
