is there anything i can do to resolve this annoying problem - just to add sometimes the laptop will start up fine and tha internet connection is automatically on without any trouble...
i tried to do this (i have found it on some forum but did not bring any effect..


Method 1: Run Ipconfig /all at the command prompt to check if you are able to obtain an IP (internet protocol) address Click Start, click Run, type "cmd" (without the quotation marks), and then click OK to open a MS-DOS command line window. Type "ipconfig /all" (without the quotation marks), and then hit the ENTER key.

Step 1: Disable the IP Helper service:

1. Hold the Windows key and type R, enter "services.msc" (without the quotes) and press Enter

2. Scroll down to the IP Helper service, right click on it and select Properties

3. In the dropdown box that says "Automatic" or "Manual", set it to Disabled and then click on "Apply"

4. Then click on "Stop" to stop the service from running in the current session

5. Click OK to exit the dialog

Step 2: Disable IPv6

1. Go to “Control Panel - Network Connections”.

2. Right-Click on the connection and click Properties.

3. Uncheck the Internet Protocol (TCP/IP) Version 6 in the list and click OK.

4. Please reboot the computer to see if it works.

Note: You should do this for each network connection.







if you have any ideas please help ...

Hi horseman -
First I assume that you have attenpted to direct connect to the modem by Ethernet cable, and have the same result - - -
If this is the case please follow these directions (Program can be transferred via USB flash drive) -

Please download MiniToolBox, save it to your desktop and run it.

Checkmark the following checkboxes:
•Flush DNS
•Report IE Proxy Settings
•Reset IE Proxy Settings
•Report FF Proxy Settings
•Reset FF Proxy Settings
•List content of Hosts
•List IP configuration
•List last 10 Event Viewer log
•List Installed Programs
•List Users, Partitions and Memory size.
•List Minidump Files

Click Go and post the result (Result.txt). A copy of Result.txt will be saved in the same directory the tool is run.

Note: When using "Reset FF Proxy Settings" option Firefox should be closed.

Thank You -

is there any kind of wifi virus going on you are aware of ??

We will never claim to know of any , or all active infections as some develop today and some are still active from 10 years ago -
But I would say "Not that I am aware of" -

These are all listed for the one log on session -

Are you locked into PCTools Antivirus system ?? If not I would say that MSE provides simpler system and Windows7 Firewall is very good -
Performance review -
PC Tools received generally excellent marks for its efficacy at detecting and removing malware.
However, CNET Labs determined that there's a high cost for those results, with abysmal marks on system performance.

"The performance strings in the Performance registry value is corrupted" shows up in errors also -
This would at minimum require a chkdsk /r and a sfc /scannow to check for corruption / errors (CDs are not required for Win7 unless badly corrupted) -

Detektor Winampa - Generally regarded as a very lo rated program (I found most reviews gave it a 1 star rating)

127.0.0.1 localhost = your Hosts file ........
Clear your cache and reset your Hosts file -
Copy and paste between these lines in Note pad. Not any other program, it must be Notepad -
--------------------------------------------------------------------------------------------
@Echo on
pushd\windows\system32\drivers\etc
attrib -h -s -r hosts
echo 127.0.0.1 localhost>HOSTS
attrib +r +h +s hosts
popd
ipconfig /release
ipconfig /renew
ipconfig /flushdns
netsh winsock reset all
netsh int ip reset all
shutdown -r -t 1
del %0

--------------------------------------------------------------------------------
Save as flush.bat to your desktop. NOTE - The .bat extension is very important
Right click on the flush.bat file to run it as Administrator. Your computer will reboot itself.
(Credit Jacee Bleeping Malware Response) -

You could uninstall these items and then try, one at a time, to reinstall them -
Need for Speed™ Carbon
Need for Speed™ Most Wanted
GTA San Andreas (Version: 1.00.00001)
µTorrent (Version: 3.0.0)

Just basic observations for now, but Remove PCTools, Remove games, Reset Hosts file -
Followed by Run a Disk Check /r and System File Check -
Get back after this if the problem persists and we can review it further -

Thanks -
