Drasticky snizeny WiFi signal (¿po updatu?)
« kdy: 07 Květen 2018, 15:26:57 »
Dobry den, poslednich par dni (pravdepodobne po nejake aktualizaci - Ubuntu Mate 16.04) se mi na notebooku (viz nize) drasticky zhorsil prijem WiFi signalu. Sedim metr od routeru a mam jednu carku... I driv byl prijem cca o 20% horsi nez na Windows, ale ted uz je to k nepouziti...
