W Fedorze 15 mój adapter Netgear WG111v2 (USB) łączy się dobrze z moim AP, pozwala na normalne prędkości pobierania około 800 kb / s przez około 20 sekund, a następnie spada do około 100 kb / s. Co jest tego przyczyną i jak mogę zmienić to na normalne zachowanie? Szybkość 800 kb / s jest normalna w systemie Windows. Co ciekawe, w dmesg jest trochę danych wyjściowych cfg80211 (patrz poniżej).
