Cannot connect to the internet (windows 7 laptop)

[joea9]

Hi, I'm trying to fix my sisters laptop, which just wont connect to the Internet. I've checked everything I can find, nothing helps, so really need some additional advice please.

Here's a description of the problem -

When looking at the icon in the system tray that shows the connection bars, when I hover over it, it says "not connected - connections are available" . On the related pop-up window It does show my wireless connection. When trying to connect to that wireless network, it eventually says "the connection was unsuccessful - this computer has limited connectivity to "bthomehub.....".

At this point it gives an option to troubleshoot, when i select this it says -

"problems found - there might be a problem with the driver for the wireless network connection adapter"

if I look at the troubleshooting report from this window it says "windows couldn't automatically bind the IP protocol stack to the network adapter"

In 'network and sharing centre' it shows the computer being connected to the homehub, but no connection from homehub to the Internet .

Attempted to ping ebay, got this response - "ping request could not find host ww w.ebay.com please check then name and try again."

under wireless connection status it says -

"ipv4 connectivity - no Internet access"

"ipv6 connectivity - no network access"

From looking around on the internet I have tried the following -

netsh winsock reset catalog

netsh int ip reset reset.log

reinstalled drivers for wireless network connection adapter

checked that windows has no restore points

tried ipconfig /release at command prompt, got the error "the operation failed as no adapter is in the state permissable for this operation"

tried ipconfig /renew at command prompt, got the error "the operation failed as no adapter is in the state permissible for this operation"

I tried removing various antivirus/system protection apps...at this point i then got a yellow icon over the connection bars in the system tray, and it now says im 'connected'. but it says 'no internet access' .

This is my ipconfig /all result -

Thanks in advance,

Joe

This might not work but is an easy start, switch off or unplug the Router for about 30 seconds then plug it back in again and wait for all the lights then try to connect

Have you tried doing a wired connection, to see if there are any problems, if no problems try configuring the wireless while connected to the wired network.

[MANEMAN]

Yeah ! what Rong and Alan have just said.

If you're no further forward you'll just have to go along with "Alan's Theme Tune" - "It's all going downhill now." and get someone in who knows what they are doing.

If you cant do a simple thing like this. ( No reflection on yourself, - because many cant.) You may just need the physical presence of someone who can.

The frightener ? - It may mean money changing hands. :(

Just to restate the answers aleady given :

C'mon back and let us know what you've done

Hi. Did you ever get a resolution to this issue? It has suddenly happened to me. One day all working fine, next day can't connect. Both wired & wireless interfaces down. AV (Avast) has been removed, drivers reloaded, no ad blocking software and all of the other tips followed. Any help greatly appreciated.

Is the service from your ISP down?

[level490]

No, ISP is fine. As is all of the hardware (both wired & wireless, as I get flashing green lights on the router). The connection exists at the ethernet level, just not at the IP level. From various posts elsewhere on the web, the issue seems to be related to someting (normally AV software) blocking the binding of the IP stack to the physical adapter. If one is lucky, poking the AV sofware fixes the issue. I have removed all of the AV software (Avast) and I still have the problem. I am wondering if the AV software deleted something ... I was hoping that someone might have another idea / solution. I don't really want to do a full Windows reinstall.

Resetting the adapters etc. using netsh has also failed to fix. Although I am not sure that I am using the correct parameters. OS is Windows 7 Home + SP1.
