Windows unable to connect to WiFi / unable to connect wireless connection in windows 7 /XP /Vista

This issue occurs because of a difference in design between Windows 7 and Microsoft Windows XP Service Pack 2 (SP2). Specifically, in Windows XP SP2, the BROADCAST flag in DHCP discovery packets is set to 0 (disabled). In Windows Vista, the BROADCAST flag in DHCP discovery packets is not disabled. Therefore, some routers and some non-Microsoft DHCP servers cannot process the DHCP discovery packets.

To resolve this issue, disable the DHCP BROADCAST flag in Windows 7. To do this, follow these steps:

1.    Click Start, type regedit in the Start Search box, and then click regedit in the Programs list.
If you are prompted for an administrator password or for confirmation, type your password, or click Continue.

2.    Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{GUID}
In this registry path, click the (GUID) subkey that corresponds to the network adapter that is connected to the network.

3.    On the Edit menu, point to New, and then click DWORD (32-bit) Value.

4.    In the New Value #1 box, type DhcpConnEnableBcastFlagToggle, and then press ENTER.

5.    Right-click DhcpConnEnableBcastFlagToggle, and then click Modify.

6.    In the Value data box, type 1, and then click OK.

7.    Close Registry Editor.

When you attempt to open a .PDF file that came as a mail attachment in Windows Mail, the following error may occur:

This file does not have a program associated with it for performing this action. Create an association in the Set Associations control panel.

This may happen even though you have Adobe Reader installed. Also, the same file may open correctly when saved to disk and then viewed.

This article applies to Windows® Vista systems with Adobe Acrobat Reader(v8.1 as of this writing) installed.

Proposed solution

This error occurs if the file type association for .PDF is incorrect. You can fix this using the steps below.

Removing .PDF file type association

• Download unassoc.zip and save it to Desktop
• Extract the contents to a folder and run the file unassoc.exe
• Select .PDF from the list and click Delete file type
• The file type association for .PDF is now removed.

Repairing Adobe Acrobat Reader

• Right-click on the Adobe Readershortcut and click Run as administrator.
  
  
  
  From the Help menu in Adobe Reader, click Repair Adobe Reader Installation.

The repair process should fix the .PDF file type association. Restart Windows and see if you're able to open .PDF attachments directly from Windows Mail.
