I’m afraid I don’t know the specific answer and I’ll refrain from guessing, but I did want to address this:
And the advice of getting a new WIFI card because of this? excuse me? why I should waste money and buy another WIFI card when this is a clear Linux problem.
Linux in general, and Fedora Linux in specific, are put together by volunteers. A lot of times, support for specific hardware is provided by heroic, passionate people who, on their own time, decipher how the hardware works and create drivers for it. But, it’s impossible to provide complete coverage of all hardware in this way.
Ideally, hardware vendors would work directly to make sure their device works with Linux. Many do, in fact — including Intel. But, it’s not always perfect, and unfortunately they don’t really provide direct end-user support. If you bought a pre-built computer sold with Fedora Linux pre-installed, that vendor could take your problem to Intel to get help. But the rest of us… unless it’s a specific known situation, sometimes all we can do is give suggestions for things to try based on what we do know.
I know that this isn’t the same as a great corporate customer-support experience. But that’s because you’re not a customer. By running a system with Linux, you’re part of the Linux community. By running a system with Fedora Linux, you’re part of the Fedora community.
Please be patient with us as we try to help you figure this out. I hope we can be friends even if we can’t get you a solution instantly.
