No network connectivity anymore

Hi,

I run a x64 version of Windows 7. Everything was working fine but after I've installed a zyxel vpn client it was impossible to connect using any of the network adapter (ethernet and wifi).

If plug in my network cable, my local area connection gets activated but there is no IP connectivity. The same with wifi connection, I start my network write the wpa key but cannot get ip connectivity.

There is a particular information in the event viewer that i m pretty sure is related to this : Windows couldn't automatically bind the IP protocol stack to the network adapter. But I don't know in what I can use this information except googling it.

I've tried using netsh to reset settings of ip stack to normal using << netsh int ip reset >>. I've also tried to re-install both ethernet and wifi drivers. Of course I did uninstall the VPN client but did'nt help either. I've run a check of the system files using sfc command and guess what : nothing abnormal.

So guys any help would be greatly appreciated

Hello,

please try to use a restore-point before installing the vpn client. This should help you in this situation.
We have the same problem with checkpoing secure client. It seems the vpn is installing a virtual nic on top of your existing drivers.

Unfortunatelz I didn't create a restore point but I did uninstall the VPN Client. Do you think the virtual nic your speaking of did not uninstall. Do you have any idea of uninstalling that Virtual nic if that's the problem.

I did find out you were right !!!  There was NDIS Filter driver installed in my connections elements and it did not uninstall when I uninstalled the VPN. So I unchecked it and problem solved. Thanks a lot
