Fedora 15 altında, Netgear WG111v2 (USB) adaptörüm AP cihazıma iyi bağlanır, yaklaşık 20 saniye normal indirme hızına izin verir ve yaklaşık 20 saniye normal indirme hızına izin verir ve ardından yaklaşık 100kbps'ye düşer. Bunun nedeni nedir ve onu normal davranışa nasıl değiştirebilirim? Windows altında 800kbps oranı normaldir. İlginç bir şekilde, dmesg'de cfg80211'in bir çıktısı var (aşağıya bakınız).
