Fixed it, heres how
I had this problem and went out and purchased a new lan card and it didnt work... plus i followed instructions from this site
Quote: updated vista, now ipv4 and ipv6 not connected - Tech Support Guy Forums TCP/IP stack repair options for use with Vista or Window 7.
Start, All Programs\Accessories and right click
on Command Prompt, select "Run as Administrator
" to open a command prompt.
In the command prompt window that opens, type type the following commands:
Reset WINSOCK entries to installation defaults: netsh winsock reset catalog
Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log
Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log
None of those worked, but heres what did!!! I found this out by myself...
AVG 2011 had a packet filter driver running and this stopped all internet access so showing those two IP4 and IP6 not connected. Once the check box for this filter driver was unticked and apply pressed, hey presto all net activity came back.
So what I would suggest is go into this place and untick any but the most essential drivers for your network card...
Control Panel, network and sharing centre, CHANGE ADAPTER SETTINGS
double click the adapter you appear to be using, ie your LAN card of your WIFI card
A window appears... click properties
A window appears witha tab "networking" and "the connection uses the following items..." Untick them all... and press ok...
Then go back into properties and reselect just these:
CLIENT FOR MICROSOFT NETWORKS - YES
INTERNET PROTOCOL VERSION 4 = YES
GO AND SEE IF YOU CAN GET NET RUNNING... IT MAY BE A BIT SLOW AT FIRST...
If you net is working... go back in and one by one click on those unticked boxes to renable and work out which ones is making the net go bye bye... and leave that one UNTICKED...
Then tick all of then except that one thats stopping your net.
Thats it. Good luck.
What ever is the one that is unticked still is probably a bad driver. Note its name and which software it seems to be connected to... like mine was AVG packet Filter Driver... and uninstall AVG and reinstall it... or in your case uninstall whatever software that driver came from... may be an antivirus or may be something else... and reinstall it. If it plays up, consider using a different piece of software made by someone else.
