Background:

• I was surfing yesterday when all the sudden my connection dropped. I have never been able to reconnect since then (see attachment "Network" for current state).
• Interestingly enough, all my other devices connected to the same network continue to work perfectly fine (2 phones, 1 tablet). Only the PC seems to refuse to connect.
• Prior to this issue, all 4 devices were connected on the same network for 2+ years without any problems at all.

What did I try?
Pretty much everything that I could think off and found on internet, including:

• Check that the password I entered was correct
• Reboot computer / modem
• Deactivate / reactivate all possible configurations of network cards
• Uninstall / reinstall Wireless LAN Card drivers (including newer versions of the drivers)
• Update motherboard / chipset drivers
• Virus and malware scans with AVG anti-virus
• System restore to time when internet worked
• Clean format and reinstall of Windows 7 (incl. new partitioning)
• Deleting the wireless profiles under Start> control Panel> classic view> network and sharing center> manage wireless networks
• Run Windows built in diagnostics tool before and after reinstall. The result is always the same: "Problem with wireless adapter or access point - not fixed"
• Deactivate Windows built-in firewall (I do not have any other firewall or anti-virus installed, AVG has been removed after scanning the whole computer)
• ipconfig /release and ipconfig /renew
• flushdns
• Set a static IP, gateway, DNS etc.
• Install Xirrus Wi-Fi Inspector and run diagnostics

Where I'm stuck now?

Everytime I double-click on my network, windows requests for my network password. I enter it and the message "Windows was unable to connect to dvr-12556" pop-up comes immediately.


Interesting (unexplained even after all I did) facts:

1. Wireless profiles:


I do not see any wireless profiles under Start> control Panel> classic view> network and sharing center> manage wireless networks.



2. ipconfig results:

3. ipconfig CMD results:



Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

• Successfully reset the Winsock Catalog.

Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log

• Reseting Global, OK!
• Reseting Interface, OK!

Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log

• There's no user specified settings to be reset

4. Xirrus Wi-Fi Inspector diagnostics results:

See attachment "Xirrus"





5. Current Wireless card settings (after I tried everything):


See several attachments "Wireless card"



Conclusion:


It seems the problem is coming from the fact that my DNS / IP adress is missing, but I feel I have tried everything to fix it without success. Any idea ?


Thanks !!
