Hello everybody,
I was playing around with the wifi cards and tried out to unplug the antenna on the wifi card on an old laptop of mine.
Well, I had no wifi signal in a range over 5 meters.
A friend of mine said he had this problem too, hp (I gues the laptop is too the pavillio 15). I told him to look after the antenna at the wifi card.
And there he saw something strange. THe wifi chip card had 2 letterings, one onboard (on the chip card) and one on the a sticker. On the onboard the wifi antenna was plugged in to the channel 2 (L2) and on the sticker it was the channel 1.
Well, he changed the channel, plugged the antenna on the L1 (channel 1 Onboard) and voila, it worked for him very well. No driver updates, no different drivers, nothing. Just the wifi antenna. (Also he had only a wifi antenna, no AUX antenna like some other notebooks)
Hope it helps for you too in that way (if the drivers are not the problem).
