My wireless connection failed suddenly one morning. It was working fine for 2 years!

The properties window of the Wireless/PRO 2100 BC adapter show it is working fine.. and the suspected corrupted driver w70n51.sys (ver 1.1.6.0) was re-installed successfully.... but still failed to connect. The WZC service failed to start although the RPC and TCP/IP stuff are nicely in place. The D-Link router has no problem as it could internet with my handheld palmtop.

I doubt the winsock is bad, as I could also connect to Internet via cable LAN.

Apprepriate any advice.

Hi jack kC,

Update Java:

• Go to Start > Control Panel double-click on the Software icon > add/remove programs.
• Search in the list for all previous installed versions of Java. (J2SE Runtime Environment.... )
  
  It should have next icon next to it:
  Select it and click Remove.
• The current version can be downloaded from Sun here: http://java.sun.com/javase/downloads/index.jsp Scroll down the page to 'Java Runtime Environment (JRE) 5.0 Update 7' and press the 'Download' button. On the new web page, click the 'Accept License Agreement' button. Then select 'Windows Offline Installation, Multi-language' in the Windows Platform area just below the Accept button.

You might want to save this page on your favorites, so you can find it again when you return. You can also click on your name and click on "Find All Posts" to find your thread.

Run HijackThis, click on "Scan" and check the boxes next to all these items.

Then close all windows, and browsers, except HijackThis. Tell HijackThis to "Fix checked".

Restart your computer in Safe Mode. How do I Safe Boot my computer?

Show hidden files. How do I show hidden files?
At the end if the fix you can return the files to hidden status if you want.

Delete the following files in red (it could be that they are deleted already):

C:\WINDOWS\system32\anti_troj.exe
C:\foo.mht

Go to "Start" -> "Run" and type in the box: "cleanmgr". Let it scan your system for files to remove. Make sure these 3 are checked and then press "Ok" to remove:

• Temporary Files
• Temporary Internet Files
• Recycle Bin

Restart your computer and post a new log in this thread.

thanks bobbi.

I followed the steps listed until "restart computer in safe-mode".

The computer failed to restart in safe-mode and kept looping to try to restart.

The computer is now crashed as I cannot restart in any mode.
Any advice wld be appreciated

Thks.
(sorry didn't reply earlier, as I was out of town)

Huh? What happened exactly? What did you do and where does it crash? The more infromation you can give me the more detailed I can search...

Hi Bobbi,
sorry didn't response earlier.
the laptop was dead. the "C" drive was even locked down. can reboot in any mode.

finally give up and sent to ACER repair centre. They repaired it with this report:

Line 1: Symptom sub code= NW07- Wireless LAN function fail
Line 1: FRU subcode= S106 - System gets virus.
Action code = SE07 - Recovery system

Well, in short, some resources were not recoverable. The whole OS was then reinstalled.

Now working fine.

Ok.... Good luck, and safe surfing.
