Hi,

Everything was ok until I started downloading a video and came up with access violation.
Following this, my wireless network connection was abruptly cut off.
I am now temporarily using Huawei Mobile Connect (mobile broadband connect) to connect to the internet.
This mobile connect is actually more for outdoors. Could just connect to sites but causes interruption when viewing
youtube videos, the circle just goes round and round. Downloading large files also gets cut off.


Here's ACCESS VIOLATION printscreen1:

Here's the ACCESS VIOLATION3 printscreen3

The network adapters in my device manger were initially shown as:
6to4 adapter (with a yellow exclamation mark) with a code 31 error
Intel® Wi-Fi Link 5100 AGN
Realtek RTL8168C(P)/8111C(P)Family PCI-E Gigabit Ethernet NIC(NDIS 6.0)

I tried to update the 6to4 adapter driver, and it says it is up to date.

When I click on show hidden, there were about
twenty over 6to4 adapters inside with additional
Microsoft 6to4 adapter #2, Microsoft 6to4 adapter #3 and Microsoft 6to4 adapter #4.

I used devcon.exe to uninstall them and it actually removed more than that, about thirty of them.
Here’s the printscreen of Network Adapters(show hidden) before uninstallation:

After uninstalling ALL OF THOSE 6to4 adapters, my wireless network connection is still shown with a red X on my taskbar.


Therefore, I reinstalled the 6to4 adapter back again but it seems that it just keeps on increasing.
There are altogether 4 of them now
Here's the printscreen after uninstallation of 6to4 adapters
In device manager, the network adapters are now left with Intel and Realtek

My network connection managed to connect online at one point when I tried MICROSOFT"S SOLUTION:
a) Click on Start > Type in computer management and hit enter
b) Under System Tools, double click Local Users and Groups then click Groups
c) Right click Administrators
d) Click Add to group then click Add then Advanced
e) Click Find Now
f) Double click on Local Service then click OK
g) NT (New Technology) Authority\Local Service should show up in the list, click OK then Reboot

After that, my wireless connection came back stronger than never.
But the wireless connection met with further access violation and download error leading to no internet connection
after I re-downloaded other videos with that particular downloading software again.
My wireless internet was immediately cut off when those access violation happened. I have since then uninstalled that software.

Should the 6to4 adapters be completely uninstalled? Or should I uninstall one of the two?

Though the signal strength is good and I can see my network SSID, I could not connect to my wireless internet.
Here’s the repair and diagnostics printscreen :

Now it could not even locate any IP address! I have not been using IE so I have not done any windows update for a long time. Firefox is my present browser.
Here's the ipconfig /all

I am using google DNS 8.8.8.8 8.8.4.4
Here's the tcp/ipv4 & ip settings

I also tried to disable and enable the wireless network connection icon but it still cannot connect.

I have also tried the below mentioned solutions from other forums like:
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
Ipconfig /flushdns
Ipconfig /release (no connection, cannot be done)
Ipconfig /renew (no connection, cannot be done)

sfc /scannow was also performed. It did find errors but unfortunately I did not save a copy of the results.
chkdsk was also done. No errors were found.

I HOPE I DID NOT MESS UP THE REGISTRY BY DOING THE FOLLOWING:
(HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters)
create a new “DWORD (32-bit) Value” entry line “ArpRetryCount” with the values set all to zero (the default value).

I even did a system restore and as it did not work, I revert back to the remaining ones until I am now out of restore points!

In have viewed many of the forums and tried many of the solutions but my wireless connection is still down with a red X.

I would be most grateful if someone can help me out.

Thank you in advance.
