Hi, I have a strange problem with a compaq windows 7 machine, I cannot access the internet at all though it is connected to the router by cable and wireless connections, both with valid IP addresses. I can access the internet perfectly with everything else connected to the router including the machine i'm using for this post. I can also see the laptop in my workgroup and access files on it, and vice-versa access files on this computer from it, but it will not access the internet. There must be something i'm missing (i'm no expert with windows 7!)

Wireless window states "Currently connected to (my wireless router)" but below says "No Internet access"
Wired lan is also plugged in.

Anyone any ideas please?

So you have connection but Internet doesn't seem to work. Is this the case with every browser you use (e.g. Internet Explorer, FireFox, etc.)?

Hi, thanks for the reply.

Nothing can connect to the internet from that machine be it browser, antivirus and program updates or anything else. It's not just on my network either, it's the same on any other network i've tried connecting to too. :D

Right click your wireless connection icon and select Repair.

that option isn't available. I have connect/disconnect, status or properties. In the status window i can 'diagnose' but the troubleshooter says it couldn't identify the problem.

I have already tried restoring to a time before the problem but that hasn't helped either.

Below is the ipconfig /all output in case that helps:

In the Command Prompt (with Administrator privileges), type (one at a time):

ipconfig /release

ipconfig /renew


If that doesn't work, type:

netsh winsock reset

And restart your computer just to make.

If the problem still persists, try updating the wireless adapter driver.

I have tried the release / renew but every time it fails to renew stating:
'An error occurred while renewing interface Wireless Network Connection : unable to contact your DHCP server. Request has timed out.
An error occurred while renewing interface Local Area Connection : unable to contact your DHCP server. Request has timed out.'

The netsh command didn't help either :D

This is not solely a wireless issue by the way, I have it hardwired to the LAN too.

Uninstall (temporarily) whatever security program you may have. And try connecting again.

Also, check your drivers in Device Manager. Anything missing or corrupted in there?

That got it! It was some webroot rubbish that was installed on it. I hadn't turned it off because there wasn't that option anywhere and I couldn't find out how to configure or inspect it's settings properly, so had left it alone until you pushed me to uninstall it. I should have tried that before now shouldn't I ;)
It's not a program i've ever used and now i've seen it in action I hope I won't ever have to again!

Thank you so so much! ;) :D
