Networking/Internet problem

Question

Hi everyone.   I'm trying to figure out why my newer desktop, a Dell Dimension 8300, 3.2GHz, Windows XP will not let me view any web pages.  It is networked to the older desktop (Dimension XPS R400, 400 MHz, Windows 98) via a Linksys router, which is connected to a Toshiba cable modem.  The older computer accesses the web fine, but when I open internet explorer on the 8300 it says 'detecting proxy settings...' for a second then displays Page Cannot Be found.  It won't even let me access my router's options at http://192.168.1.1...  I have tried unplugging the router and modem to let them reset, which is what I typically do when this happens, but it didn't work.  The built-in network adapter on the motherboard, an Intel PRO/100 VE, doesn't seem to shut off when the computer is off, therefore not allowing me to reset the connection.  I tried uninstalling the device and system restore but nothing seemed to work.  I don't think it's a hardware problem, but perhaps something with a connection setting.  The only thing is all my settings under network and internet settings are correct and how they should be.   The connection on the 8300 does recognize the cable if is plugged or unplugged, and there are small numbers of packages being sent and received.  It will even ping IP's in the command prompt with 0% package loss.    Occasionally it will also say little or no connectivity.  It has said that before, and all I needed to do was unplug the modem and router to correct that.  Problem is, the ethernet jack on the computer is always powered and won't connect to the internet.  Even with the computer off, my modem says it is connected to the PC, which has never happened before.   Can anyone help?  I'm thinking the proxy message might have something to do with it, but under the control panel all the internet settings are fine.   Thanks, Matt   Edit: I even tried just the cable modem connected to the computer with USB, and it still didn't work... Message Edited by gibinaw on 10-18-2004 07:17 PM

Try running winsockfix for XP from the following site:

http://www.spychecker.com/program/winsockxpfix.html

and if that doesn't help, try lspfix from the following site:

http://www.cexx.org/LSPFix.exe

Also make sure that you system is free of spyware and malware.

Hmm... Thanks for the suggestion, but that didn't seem to do the trick.  I did manage to reinstall winstock2, which helped, but it still displays 'little or no connectivity.'  The major problem now is I can't seem to get an IP address.  Should I reinstall the TCP/IP protocol?  Under network properties, uninstall for this protocol is grayed out.  Any other suggestions?   Thanks again, Matt

You can try resetting the TCP/IP stack. For Windows XP, the instructions can be found at:

http://support.microsoft.com/default.aspx?scid=kb;en-us;Q299357

Also, if you open Internet Explorer and go to Tools > Internt Options, click on the Connections tab, then click on the LAN settings button, are all of the boxes in LAN settings unchecked? They should be.

That didn't seem to work either.  I noticed that even with the computer off, the router and modem recognize the PC as on, and it never does that for the other computer...

Copy and paste into Notepad, save the file, copy the file to a CD or floppy, move the CD or floppy to the other computer, open the file, copy and paste the text into a forum message. Steve

What you are seeing is the Wake On LAN feature of the network card. This should have absolutely no effect, because when you reboot or power on the computer, Windows will automatically request a new IP address from whatever dhcp server is connected. It is apparently not getting an IP address from either the router or the modem. Since the USB connection does not work either, I doubt the problem is with the network card, and that's why I suggested fixes to winsock and the tcp/ip stack, since both of them would affect both USB and ethernet connections.

After resetting the cable modem and router, open a command prompt window and type ipconfig /all followed by Enter. Copy and paste the output from this command into a new forum message, and perhaps we can detect where the problem lies.

Do you have any need for the Tunnel Adapter (it supports IPv6 protocol). If not, see if removing that adapter from network properties solves the problem. See the following (note that you should page down past the advertisements to see the accepted answer that worked in that situation:

http://www.experts-exchange.com/Networking/Microsoft_Network/Q_20775223.html

If there are any other adapters that you do not use or if there is a network bridge listed in network properties try removing those as well.

Although I doubt it is a firewall problem, just to be sure, if you are running any software firewalls, temporarily disable them.

Oh man, i am having the same problem, only none of my computers can connect.  I was using my existing true mobile wireless router fine with my laptop via wireless and my desktop via ethernet cable.  I wanted to be able to change my router settings so i tried to load the router software onto my desktop.  It brought me to a connection wizzard and I ran through the steps, mind you I already had a connection that worked fine but I didnt see the harm in it.  I got to the end and the wizzard wigged out and gave me 10,000 error messages.  I closed the application through the task manager and ever since i cannot access the internet with any application.  My network connections are recognized in the manager and I can see the few packets that had passed in and out.  I tried to disconnect the router and go straight to the cable modem with the desktop but with the same result.  No connection.  Could it be my proxy server settings? F.

First, of all, it gets very confusing trying to address 2 different problems in the same thread. This thread was started by gibinaw, and I would prefer to deal with that problem here until there is a resolution. You should start your own thread and the forum members can start to help you in your own thread.

Before you post a new thread, however, note that you do not need any software to configure most routers, as all of the settings can be accessed through a web based configuration utility. Look in the manual that came with the router and find out how to connect to the router through the web based configuration utility. Note that it is best to do this through a wired connection rather than a wirelss connection. Then, if you can't resolve the problem using that utility, start a new thread, and give the details of your router model, version(s) of Windows involved, network setup, and what you have done to attempt the to fix the problem. Then perhaps someone can help you.

I deleted the protocol but I am still having a problem.   Byt the way, when I try to open windows firewall, it asks if I want to start the Windows firewall/Internet Connection Sharing (ICS) Service because the associated service is not running.  (I think this is alg.exe, but when I try to open it, it does nothing.)  When I click yes, it tries for a second then displays that windows cannot start the windows firewall/ICS service.   -Matt

volcano11 · Answer

Matt,

alg.exe is the Application Layer Gateway Service that should be a running process. Go to start > Run and type services.msc followed by Enter. Click on the Application Layer Gateway Service and in the left hand pane, click on Restart the Service.

This reminds of me another possible reason your internet connection could be broke. Did you recently uninstall Norton Antivirus. I friend of mine found that his interenet connection no longer worked after uninstalling Norton Antivirus. I eventually traced the problem to the fact the uninstalling Norton did not delete 2 registry entries that prevent the dhcp client service from starting before Norton Antivirus is loaded. Manually deleting the registry entries solved the problem. To check to see if this is the case on your system, while in the Services program, look at the DHCP client entry and make sure that service is started. If it is not started and you cannot start it from within the Services application, it could indicate a registry entry that is preventing it from starting.

Has this computer ever been able to connect to the internet with either USB or ethernet?  What other software has been installed or unitnstalled on the computer?  Has it been upgraded to SP2?  Steve

volcano11 · Answer

So is this a new problem? Can you now enable/disable the XP firewall? Does setting the Application Layer Gateway Service back to manual (that's what is set to on mine) solve the taskbar problem? And, back to the original problem, Is the dhcp client service running?
