I did read you posts(s) but nowhere do you state you are using a static IP.

To collect IP configuration information easily, do the following:

Open a Elevated Command Prompt:

Press WIN + X to open Start context menu.
Select Command Prompt (Admin)​.

Paste the following into the Command Prompt window, exactly as shown, including double quotes:

cmd /c "ipconfig /all > postme.txt & ping yahoo.com >> postme.txt & reg query "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings" | find /i "proxy" >> postme.txt & notepad postme.txt & del postme.txt"

and press ENTER.

A file will open in Notepad. Please copy and paste the contents here. Close the Notepad window and the file will be deleted and the Command Prompt window will also close. Post results in a reply here.
