I can connect Ok to internet/network with an ethernet cable but my wireless connection has stopped working. The wireless connection properties shows all boxes ticked and Ipv4 & ipv6 are set to addresses being automatically assigned. However the wireless connection status says that both of these are not connected. I have tried uninstalling the wireless driver, when it reinstalls the problem is still there.



Any suggestions?

Hey DW

First thing we could use is some info abt your sys specs, wifi card, and OS (32 or 64)

Ken

Machine is Acer Aspire 7720Z Pentium Dual CPU T2310
os is 32bit
wifi card Atheros Ar5007EG

This had all been working fine until a few days ago. I did install AVG 8.5 free edition last week as I had some sort of virus. This has been cleared up now, I think the wireless was working after installing AVG but I can't be certain

I am having the exact same problem. I completed a windows update, and since then I have been unable to connect to the internet. Both my IPv4 and IPv6 connectivity shows up as: Not connected, though both boxes are checked off and set to automatic. Does anybody know what I can do to fix this? Microsoft support is $59, and I can't get my computer to connect with an ethernet cable, so I'm at a loss here. Please help.

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

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

PRESS OK

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.
