My boss' computer TOSHIBA Satellite L40-A suddenly cannot connect to the internet anymore after he installed Kaspersky Internet Security (multi-device). Because of this, he uninstalled the Antivirus but still cannot connect to the internet.

on Command Prompt, typing ipconfig /all will only display the following:

-------------------------------------------------------------
Windows IP Configuration

Host Name . . . . . . . . . . . . : Toshiba
Primary Dns Suffix . . . . . . . :
Node Type . . . . . . . . . . . . : Hybrid
IP Routing Enabled. . . . . . . . : No
WINS Proxy Enabled. . . . . . . . : No
-------------------------------------------------------------

There is no ethernet or wireless LAN settings displayed.

1.) I tried netsh int ip reset reset.log but it's says RESETTING , FAILED. see below:

-------------------------------------------------------------
Resetting Global, OK!
Resetting Interface, OK!
Resetting Unicast Address, OK!
Resetting Neighbor, OK!
Resetting Path, OK!
Resetting Route, OK!
Resetting , failed.
Access is denied.

Resetting , OK!
Restart the computer to complete this action.
-------------------------------------------------------------

On the other hand, netsh winsock reset catalog is successful.

2.) I have also tried updating the wireless adapter (Qualcomm Atheros AR956x) driver into the latest version which is 10.0.0.329 but still no luck.

3.) I have also tried uninstalling the wireless adapter driver and restarted. the laptop automatically reinstalled it with the latest driver version but still the same.

4.) I tried using a wireless WIFI adapter to isolate the problem but it still cannot connect to the internet and also not displayed when running ipconfig /all.

I have successfully gained access and reset netsh.exe using the following link, but still did not fix the problem.

Use the Kaspersky removal tool to remove any left over components: http://support.kaspersky.com/common/service

Was there a previous security program on the computer? If so you may need to run it's removal tool as well.

Also check Internet Options in the Control Panel for a Proxy, if there is one you should disable it. It's under Connections then LAN Settings.

Can you post the results of running the following command in a command prompt:

IPCONFIG /ALL

Easiest way is to run it with the option to directly copy it into the clipboard so you can just paste it here.

IPCONFIG /ALL | CLIP

Well your issue is that you don't have any interfaces listed in the IPCONFIG.

Do you see them if you go to Control Panel / Network and Sharing Center? If so are they disabled?

If you don' t them there, do you see them in Device Manager?

Jeez, that shows me for using mobile and missing that entire section.

I wonder if they are indeed both listed in Device Manager with errors and needing a reinstall.

I missed the first time myself so don't beat yourself up on that :D

OC6 - I also skimmed past this:

4.) I tried using a wireless WIFI adapter to isolate the problem but it still cannot connect to the internet and also not displayed when running ipconfig /all.

Did you see this in Device Manager / Control Panel as well? If not then it sounds like Kaspersky is locking down the network connections.

Triple6: I already tried reinstalling a new driver, downloaded an older driver version... not working for both.

Couriant:
It is ENABLED in the NETWORK AND SHARING CENTER.
It is shown in the DEVICE MANAGER... with NO ERRORS.

Kaspersky has already been uninstalled and I have also tried the Kaspersky removal tool.
