I took advantage of the free Windows 10 upgrade recently and now my Wi-Fi adapter won't work. I thought I had done my homework, at least on the Microsoft site, to ensure that my machine would be compatible. Now that I check even further, I see that Inspiron 3520 is listed as not compatible on the Dell site. Unfortunately it was more than 30 days ago, so the easy open to just revert back has disappeared from the machine. Do I have any option other than to just completely re-install 8.1? Of course I haven't a clue where my original documentation and system discs are now, since my machine is almost 4 years old and I haven't had any issues like this before.
Help?
