Bridge Connections (WiFi) no longer work with an unexpected error.

Hi,

There are a lot of possible factors for the bridge connections to have an unexpected errors. To isolate this matter,
I have a couple of questions for you:

• 
  Were there any changes made before the issue occurred?

  Have you tried updating your drivers manually?
  
• 
  What troubleshooting steps have you done so far?
  

I recommend that you perform the troubleshooting steps indicated in the article entitled

If the issue persists, reset your TCP/IP and see if there are any changes. It is possible that your TCP/IP were
corrupted. To do this, follow these steps:

    and hit
    Enter.
    

Exit

and
monitor your network connection.

Disable auto turn-off of

  Uncheck/disable
  the check box radio for

• 
  Restart the PC
  (Important).
  

Reconfigure TCP/IP

To do this, follow these steps:

• 
  Run
  Command Prompt
  as
  Administrator.
  
• 
  Run
  these following commands:
  
  • 
    netsh
    int
    tcp set heuristics
    disabled
    
  • 
    netsh
    int
    tcp
    set global
    autotuninglevel=disabled

Let us know how it goes.

Windows 98 and ME no longer updatable...

Quite right, XP is still listed in technet. Win 98 unfortunately isn't. Windows 3.1 and 3.2 are listed though.
