lose internet connection, have to reboot to get it back

by td92 / September 10, 2004 11:48 AM PDT

i've had this problem for a couple of years now and i'm pretty fed up with it. i dont know how to narrow it down except for reformatting, which i've done 3 times since it started.

the problem is i can either be surfing the net, or playing an online game, and i will lose my connection to the net. the only fix is for me to reboot my computer. i am on cable internet.

the most recent time i have reformatted, i only put the basics on my computer. i downloaded an Nvidia driver for my vid card, and the latest Direct X version. i also downloaded XP's recent hotfixes. i believe that the problem is with the hotfixes. it ran fine til i got those.

i've downloaded XP service pack 2 in recent months and it did not fix this problem at all. should i reformat again and not download fixes and updates for XP anymore?

is there anymore info that i should provide?

A few ideas.

1. Case cover off. Heat can cause parts to do that.

2. Motherbaord and network drivers are not supplied by Microsoft. Your post didn't tell about those.

the problem is i can either be surfing the net, or playing an online game, and i will lose my connection to the net. the only fix is for me to reboot my computer. i am on cable internet.

Specifics would be required of what you've investigated and what may be found to indicate the problem! Once something has been zeroed on, possible resolution might be forthcoming.

1. The article [Q305549] explains step-by-step of how to configure a connection to the Internet using the Network Connections tool in Control Panel.

2. The article [Q320558] discusses and warnes that if you use the New Connection Wizard to create a new dial-up modem or PPP over Ethernet (PPPoE) connection, you may experience any one or more of the following issues and therefore cannot create a dial-up modem connection or PPPoE connection to the Internet unless the fault is corrected in the system registry:

a. The Connect using a dial-up modem option in the New Connection Wizard is unavailable (appears dimmed).

b. The Connect using a broadband connection that requires a user name and password option in the New Connection Wizard is unavailable.

3. Please read through the article [Q314095] which describes ways to diagnose and resolve issues that can cause problems when you try to use an Internet browser, File Transfer Protocol (FTP), or Telnet to communicate with servers on the Internet. Also be aware of the discussion in the article, "Windows XP Internet Programs Cannot Connect to the Internet Through Broadband Connection (Q307164)," as necessary.

4. The article [Q813444] contains information and procedures used to troubleshoot situations where you cannot connect to SSL Secured (128-Bit) Web sites (https: followed by TWO forward-slashes).

Note: The following are areas discussed that in my opinion should be looked at closely:

a. Create a new User Profile - [User Accounts].

b. Register files - download and use "IEFix" - a general purpose fix for Internet Explorer (Win 98/ME/2000/XP).

c. Verify that the Microsoft Cryptographic Services service is started - [Q822798].

5. If IE appears to stop responding (hangs) when opened but the animated globe in the upper-right corner of the browser window continues to spin, look to see if there is a message in the status bar such as Detecting proxy settings... [Q220902] and report that information for further assistance.

6. The article [Q314067] explains that there are utilities that can provide useful information when you are trying to determine the cause of TCP/IP networking problems and lists recommendations for use. Although the list is not complete, it does provide examples that show how you can use them to track down problems on the network setup.

7. When using a multiple-homed WinXP-based computer with the Personal Firewall feature enabled, remote users may not be able to connect to the computer in response to a Remote Assistance request. If a network adapter and a modem with the Personal Firewall feature is enabled, Remote Assistance may not open the firewall port on the modem connection which can occur because Remote Assistance opens the firewall port only on the first bound network adapter of the multiple-homed computer, [Q308210].

8. The article [Q329441] explains that if you install Service Pack 1 (SP1) and then use the System Restore feature to restore Windows to a state before the installation of the service pack, you may experience the following symptoms:

a. You cannot create a remote access or Dial-Up Networking connection. All items on the "Network Connection" page of the New Connection Wizard are unavailable (dimmed).

b. The Network Connections folder is empty.

c. The Internet Connection Sharing (ICS) and Internet Connection Firewall (ICF) services do not start because of a dependency failure.

Note: In addition, this article describes and covers several type events which are recorded and displayed in the System log of the Event Viewer.

9. These two articles describes how to manage stored user names and passwords on a computer:

"HOW TO: Manage Stored User Names and Passwords on a Computer That Is Not in a Domain in Windows XP (Q306541)"


"HOW TO: Manage Stored User Names and Passwords on a Computer in a Domain in Windows XP (Q306992)."

a. You can use the Save Password option so that your Dial-Up Networking (DUN) password is cached and you will not need to enter it on successive dial attempts. The Remote Access Service (RAS) password for DUN is recorded in the system registry with parameters as follows:


[Dword]: Value Name and Value Data


0 [zero (disabled and password saved)]

1 [one (enabled and password is not saved requiring it to be entered on each session)]

b. The article [Q315231] describes how to configure Windows to automate the logon process by storing your password and other pertinent information in the registry database.

(1) This feature allows other users to start your computer and use the account that you establish to automatically log on and can pose a security risk.

(2) If you set a computer for automatic logon, anyone who can physically gain access to the computer can also gain access to everything that is on the computer, including any network or networks that the computer is connected to. In addition, if you enable automatic logon, the password is stored in the following registry key in plain text. The specific registry key that stores this value is remotely readable by the Authenticated Users group. As a result, using this setting is appropriate only if the computer is physically secured and if you ensure that untrusted users cannot remotely see the registry.


c. The article [Q322962] warns that when you try to log on to WinXPPro, you may receive the following message that occurs when your password is set to expire after a predefined number of days and explains how to prevent the password on a local user account from expiring:

Your password will expire in number of days. Do you want to change it now?

Note: In addition, the article [Q321305] describes the procedure should you have forgotten your password, or if your password expired and you cannot create a new one. In essence, if you have not created a password reset disk and you have also forgotten the password for all user accounts, you cannot log on to your existing Windows installation for security reasons. This information applies to starting Windows XP typically, to Safe mode, and to Recovery Console. In this case, you must perform a clean installation of Windows, re-create all user accounts, and reinstall all of your programs.

d. In addition, the XP interface provides an opportunity to set a permanent Internet connection when Fast User Switching is enabled. This wizard provides a prompt for choosing between the default, Anyone?s use which means the connection will stay open when switching to another user, or My use only which will drop the connection when a user switches. It may be useful to keep a Dial-Up Internet connection open simply because if it is not, a guest account will not be able to access the Internet using Dial-Up.

(1) Click Start, Run, and type regedit.

HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon

Note: Click the Plus box in front of HKLM to expand it and continue clicking/expanding appropriate folders (each word preceded by a backslash in the above address) until reaching the last, "Winlogon". Click it, to bold/highlight.

(2) Right-click in the right pane, select New, String Value, and name this key KeepRasConnections.

(3) Double-click this key and set the value to 1 (one).

(4) Click Registry in the main menu and select Exit to save the session. Or simply click the x in the URHC of the window to close the Registry Editor tool. Respond with an affirmative to save the editing and to close the editor.

I have cable also, and when my laptop would boot me off after say about 10 mins, I discovered by going into the device manager, adapters, and in the properties under power management, I disabled "allow the computer to turn off this device..." solved the problem. I figured if I was reading a long article or something, the computer was thought I was being idle, so turned off the network adapter to save power. Since then, I disable that function on all my networked computers.
