Can't connect to Internet

February 26, 2009 at 12:03:33
Specs: Windows XP
Have had a home network operating for several years. Have my wife's IMac and my son's PC on the network and both get to the Internet just fine. The host unit also has no problem reaching the Internet. My laptop automatically detects and connects to the network but I get the standard 'can't connect' message when I click on IE. What should I be looking at, please?

Did the ipconfig, and would be happy to transcribe any/all of it, but I'm guessing I may have spotted the issue. Media state is "media disconnected". In my ignorance. I checked all 3 of my network adapters through device manager and they are all enabled and apparently operational.

Please post the results of the ipconfig /all

You looking at it and I looking at it are two very different things.

Thanks for the ipconfig.

You have two adapters; wired and wireless
Clearly you aren't using the wired which is why it comes with with media disconnected. No problem there.

Your wireless is working and you are getting good ip.

I can ping both listed dns server which is also good.

But these do not look right
IP Routing Enabled "Yes"
WINS Proxy Enabled "Yes"

Both should be set to no. You must have clicked on bridging your wired and wireless interfaces at some point in time. Undo that bridge.

You would do a reg edit to disable wins proxy
How to disable WINS Proxy

To disable wins proxy, go to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Netbt\Parameters, change the value to 0.

Value Name: EnableProxy
Value Type: REG_DWORD
Values: Boolean (0 or 1)
Default: 0

Lets see if fixing these two things fixes your access issue.

First of all, I still can’t get on to the Internet – generating the same error message as before. (Not complaining) Second, this is undoubtedly “operator error”.
To set the stage, throughout all the steps below, I was using “ipconfig/all’ in Command Prompt to verify the settings in question.
It may help to know that before this weekend I had never used Registry Editor – in fact never knew it existed. As a result, this became a learning experience.
Started with settings of “yes” in both IP Router Enabled and WINS Proxy Enabled, as shown in Command prompt.
Used regedit.exe to go to:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Netbt\Parameters\ Enable Proxy.
Set value to “0”.
Closed Registry Editor.
Did fresh “ipconfig/all”; confirmed WIN proxy setting changed to “no”
Restarted computer.
Clicked on Internet Explorer; received same error message.
Wasn’t sure how to set the IP Router Enable to “no”, so did some research.
Came up with 2 registry entries that looked as though they might be pertinent”.
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Remote Access\Parameters\IP\EnableNetbtBcastFwd
Set value to “0”.
Failed to check “ipconfig/all”
Set value to “0”
Closed Registry Editor.
Did fresh “ipconfig/all”; confirmed IP Router enable set to “no”
Clicked on Internet Explorer; received same error message.
Restarted computer.
Clicked on Internet Explorer; received same error message.
(must be a service in the services list for startup that is doing a reset, ‘cause the next ipconfig check shows them both set back to “yes”)
By the way – probably not important – but the settings on the “hub” computer in my network has both of these set to “yes”.

Hub computer???

Do you mean you are using a pc as a router to get this pc to the internet?

In which case those settings, well at least ip routing, would be correct. But you would not have those set on a computer that isn't doing routing which this problem computer shouldn't be doing.

But you can't be doing ICS [internet connection sharing] since ICS uses 192.168.0.x for ip not 192.168.1.x

When booted and not connecting to the internet can you ping [your gateway]?
Can you ping the listed dns servers?

Problem list:

Don' t know what you mean by "hub" computer
Please post an ipconfig /all from this hub computer for review
Those entries going back after you changed them either indicates your dhcp server is providing them or you have a software application that is putting everything back after a reboot.

Please describe what network equipment you have [router/switch/wireless], who your isp is and how both computers physically access the internet.

Disable the windows firewall or other third party software firewall to make sure its not blocking your access.
