I tried to update an old Dell XPS 15" from 2011 with Windows 7 installed.
First I tried to install the updates but I always had network errors like "The updates can't be downloaded"
I try to use the ping
command and it worked.
But when I tried to load a web page I had again a network error.
After I tried to boot into safe mode and I managed to load some websites (but this mode prevents to update Windows)
Do you have any suggestions ? Why can't I load web pages ? It's like a port is blocked by a software, I don't know...
