    I have no idea what happened but after putting a new MoBo into my old laptop (AFAIR wlan worked fine on it before) laptop stopped detecting WiFi card.

    I have two wifi cards - one Atheros (laptop should not boot with it cause it's not whitelisted) and two - Broacom.

    The thing is, if I put in any of them, laptop will boot normally just without seeing the WiFi card. ONCE it happened, that it displayed proper error message "unauthorised Wifi card installed" but after next restart it was no longer the case.

    Looks like something happened to the WiFi port or some itnernal connection, but I took the laptop apart twice and saw no sign of anything that might have been wrong.

    Any ideas?

    Bad board? The WLAN randomly not being detected was one of the first signs of the failing nVidia boards (of which I've been through myself).

    That would be the second one.
    But this one seems to be deprived of the famous overheating bug cause it runs 20 C lower than the previous HP frying pan I replaced with this one upon failing.

    Hmmm. Surprising, considering it is still using the same chipsets that were responsible for the fiasco originally.

    If it goes anything like mine, first the WLAN disappeared, then I had problems powering it up, and then finally nothing at all except for lights.

    Were one of those Wifi cards in the original board? I wonder if it could have been damaged during the first overheat.......

    My current wifi card likes to randomly stop working. Possibility of a relation to the above problem?

    Most likely due to HP's famous wifi problem. I have a Dv6000 and I know it's a huge issue where the card would generate way too much heat and just eventually burn out. If you don't fix the problem, it'll continue to generate more heat and eventually just burn out the entire motherboard. What laptop do you have?

    I already reflashed. And this is not the problem of the card, cause I have two and neither is working.
