Wifi adapter could not bind IP protocol stack to network adapter

Hello!

I registered to forums to get help to solve wireless adapter issue I am having.

I have been looking for help in Lenovo forums and AV provider: problem is still on.

Background

I changed AV software from Symantec to F-Secure. I uninstalled Symantec software and installed F-Secure software. Laptop is Lenovo T520.

What happened

First I recognized that ping commands caused Windows to crash. Then I uninstalled some VPN softwares and ping started to work. Operation did something to wireless and LAN connections, they did not work anymore.

LAN started to work by removing LAN drivers from device manager and reboot. After reboot Windows reinstalled LAN drivers and LAN was ok.

Wireless is a pain in there. I have tried almost everything. All Lenovo provided network softwares and power management tools are uninstalled and reinstalled together with wireless drivers. Wireless driver is not recognized by Windows.

None of automatic repairs or wifi uninstallation operations have corrected problem.

I collected some logs which might help, but now I do not know how to proceed. Windows reinstallation is something which I do not want to do.

It seems there is collision between Windows registry and device manager?

What can I do to repair wireless?

Thank for your help.

Hello!

Windows service WLAN AutoConfig is started and and running. Service has been running all the time. It seems Windows service does not do the trick this time.

Thank you for your help.

Hello!

I ran commands succesfully followed by Windows reboot. Unfortunately, wireless bind error still persists.

All drivers are latest ones available from Lenovo T520 driver download page.

Thank you for your help.

Hello!

Since I have struggled with situation more than two months, system recovery is not an option.

I ran sfc /verifyonly, output is below.

C:\temp>sfc /verifyonly

Beginning system scan. This process will take some time.

Beginning verification phase of system scan.
Verification 100% complete.

Windows Resource Protection did not find any integrity violations.


Thank you for your help.

Is there a way to remove completely wlan drivers and wlan nic so wlan card and drivers can be re-registered from scratch?

Ok... Hold your breath.

Issue was resolved by installing Cisco VPN Client. Quite interesting.
