Solution: Can't Browse the Internet After Installing / Upgrading AVG Anti-virus | How to Remove AVG Miniport

Problem:
Can't browse the Internet after installing or upgrading AVG 9.0

Symptoms:
  1. In some system, Local Area Connection (LAN) says the cable is unplugged even though it is plugged in.
  2. IPConfig command returns nothing.
  3. In the Device Manager under Network Adapters, there are several entries of AVG miniport driver and these entries have yellow exclamation mark. ("WLAN Miniport (IP) - AVG miniport driver")
  4. Properties shows: "Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19) Click Troubleshoot to start the troubleshooter for this device."
  5. You cannot uninstall the AVG miniport driver entries (remove or delete). Update and rollback doesn't work either. System Restore will not help.
Screenshot:

Culprit:
The devices appear because they are called up by registry entries which should have been deleted as part of the AVG uninstallation

Solution:
Uninstall your network adapter (the one without exclamation mark) and install it again. This usually solves the internet connection issue but the AVG miniport driver entries still exists.

How to remove AVG miniport driver entries in Device Manager:
Try any of the following solutions:
  1. Go to Network Connections and disabled then re-enabled Firewall protection for your network connection.
  2. Download and use AVG remover. It is a cleanup utility provided by AVG to remove any trace of AVG antivirus.

Japanese Keyboard Not Functioning Correctly After Installing Windows 7


This is a common problem for laptops bought in Japan. Japanese laptop = Japanese OS. If you want to convert it to English operating system, you will face a very common problem after converting.

Problem: After upgrading/converting your OS (Windows Vista to Windows 7), your Japanese laptop keyboard is not functioning correctly (different layout). The most common affected keys are the @ sign which is located along with number 2 in standard keyboard, (, :, +,

Reason: Windows Vista and Windows 7 somehow identifies some Japanese keyboards as an English device.

Solution: You will need to go to the Registry and tell Windows that you have the standard 106/109 Japanese keyboard instead of the English 101 version.

Go to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\i8042prt\Parameters
and change the following entries to this value:

LayerDriver JPNREG_SZkbd106.dll
OverrideKeyboardIdentifierREG_SZPCAT_106KEY
OverrideKeyboardSubtypeDWORD2
OverrideKeyboardTypeDWORD7

If you don't know how to do it, here's the step-by-step guide from Microsoft:


  1. Click Start
    Start button
    , type regedit in the Start Search box, and then click regedit in thePrograms list.

     User Account Control permission
    If you are prompted for an administrator password or for confirmation, type the password, or click Continue.
  2. Locate and then click the following registry subkey:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\i8042prt\Parameters
  3. Right-click LayerDriver JPN, and then click Modify.

    Note If the LayerDriver JPN registry entry does not exist, create it. To do this, right-click a blank area in the details pane, point to New, and then click String Value. Then, typeLayerDriver JPN to name the new string value.
  4. In the Value data box, delete the existing value, type kbd106.dll, and then click OK.
  5. Right-click OverrideKeyboardIdentifier, and then click Modify.

    Note If the OverrideKeyboardIdentifier registry entry does not exist, create it. To do this, right-click a blank area in the details pane, point to New, and then click String Value. Then, type OverrideKeyboardIdentifier to name the new string value.
  6. In the Value data box, delete the existing value, type PCAT_106KEY, and then clickOK.
  7. Right-click OverrideKeyboardSubtype, and then click Modify.

    Note If the OverrideKeyboardSubtype registry entry does not exist, create it. To do this, right-click a blank area in the details pane, point to New, and then click DWORD (32-bit) Value. Then, type OverrideKeyboardSubtype to name the new DWORD value.
  8. In the Value data box, delete the existing value, type 2, and then click OK.
  9. Right-click OverrideKeyboardType, and then click Modify.

    Note If the OverrideKeyboardType registry entry does not exist, create it. To do this, right-click a blank area in the details pane, point to New, and then click DWORD (32-bit) Value. Then, type OverrideKeyboardType to name the new DWORD value.
  10. In the Value data box, delete the existing value, type 7, and then click OK.
