I can't manage to go back to an old driver, even when I uninstal the card and Windows reinstal it by himself on the restart of my computer, it seems to be already and Intel faulty driver.
Do you guys have an idea where I could download the proper windows driver (can't find it on Intel website) and then force this one to be installed?
Thank you in advance.
For the record, by tweaking a lot the advanced settings, the bluetooth settings etc. as mentionned in several posts, I did managed to get the card to work properly for several days. Then out of nowhere, problems were back again!
