Brian A. I believe I have a similar problem to Ravix.

Whilst browsing trouble free I will loose conectivity. I use the Windows

diagnostic tool to determine the problem. The problem is fixed but occurs

every 15 mins or so. Your previous explanation to Ravix was a bit too tricky

to understand. Appreciate any assistance you can provide.

 

Thanks

Hi Prangie,

Could you please give more Info about your Operating system, how many

machines involved in the connection, are you using a Router/Modem.

What did you tired, what firewall you have installed on this problematic

machine (S).

I seen in the past, this can happen if you performed in the past incomplete

uninstall of protection software which left orphans behind causing this issue

to arise and losing connection.

Also bad Line, noise in the line can make you lose connection.

More info for anyone to be able to help.

HTH.

Hi Prangie,

Let's start with simple approaches:

= Do you use WEP or WPA encryption method for this Wireless?.

If you don't, I advise you to implement an encryption method to secure your

connection, preferably WPA more secure than WEP.

 

= Open the PC-Chillin firewall and allow full access to the DHCP to the

internet, it looks like when your computer try to renew the IP from the

Router the Firewall blocking it causing the Lose of connection, also the

Network Name (SSID) be allowed or trusted in the Firewall (make sure you

select the right Name not the Neighbour name?).

 

= Click start >> Control panel >> Network and Internet Connections >> Network

Connections >> Right click the wireless connection and select properties.

On the Wireless properties click on General tab then highlight the Internet

Protocol TCP/IP then click on properties, make sure the machine getting the

IP address Auto and the DNS Auto too!.

Click Advanced button click IP Settings Tab, make sure the DHCP Enabled and

Automatic metric check box is checked.

 

= Make sure the DHCP server/Host is enabled on the router Configuration

Page/interface by typing the IP address for the router on the Browser

address:

192.168.0.1

Here are steps see your settings, it will be different according to your

Location (country & ISP):

By typing the IP: 192.168.0.1 click [OK] or Hit Enter;

You will get Login into the router:

Before you can change any settings, you need to log in with a password. if

you have not yet....

How to setup wireless router

http://www.microsoft.com/windowsxp/using/networking/setup/wireless.mspx

4 steps to set up your home wireless network

http://www.microsoft.com/athome/moredone/wirelesssetup.mspx

 

= Check the Power settings for the NIC, make sure the computer not

configured to turn this device when it is Idle for power saving feature by

going to Device Manager and expand the Network Adapters, then select your

Wireless NIC, click Properties then Power management/or settings and uncheck

this check box:

[ ] Allow computer to turn OFF this device for power saving or something

similar.

 

= If you are using the Manufacturer of the Wireless Card Utility to manage

the wireless Connection , then you need to turn the WZC OFF, as if both

running they can conflict and cause the lose of connection, or turn the

Manufacturer wireless Utility and use the WZC utility to manage the

connection:

<Quote from old Post::>

I recently had this issue with a client, how installed the Wireless

manufacturer Utility to manage the connection, while the Windows Zero

configuration (WZC) was ON.

Both the manufacturer and WZC were conflicting and making the Wireless lose

on start or after a while.

Try to Disable the WZC if you have the wireless Adapter/USB or whatever kind

of wireless manufacturer utility installed and Also be sure the Wireless

Utility for the manufacturer is Auto running in the servcies.

If you have just the windows Wireless utility to manage the wireless

connection then proceed:

 

Try this:

Open a Run Command and type in:

services.msc click [OK].

On the services control Panel scroll down to Windows Zero Wireless

configuration and Be sure the service to start Automatically instead of

manually.

Click Ok then close the services control panel window and Reboot and see if

the service will hold it's settings to Auto.

If not then try this Key in the Registry:

Open Run and type in:

regedit.exe click OK and on the Registry Editor Locate this key and change

the value in the Right Pane/window to (2):

[-]HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WZCSVC =

 

[ON]Start REG_DWORD 0x00000002 (2)

 

 

[-]HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\wscsvc =

 

ON]Start REG_DWORD 0x00000004 (4)

 

Be worn, backup or write down the settings before and after the editing, if

any thing gone wrong you can restore back.
