Dear aleki_intel,

Thank you for your reply. I already know about those pages ... the problem is that I am using the latest firmware and my wifi card is still not working properly.

From your reply I understand that I should write to 'mailto:mailto:linuxwifi@intel.com linuxwifi@intel.com' or 'mailto:mailto:linux-wireless@vger.kernel.org linux-wireless@vger.kernel.org'? Is that right?

Best regards,
