I had initially thought that maybe the little CPU in the BeagleBone = wasn=E2=80=99t up to the WPA encryption or the interrupt rate + usb = where just too much for it. Sometimes changing channels helps for a = little bit. Since I=E2=80=99ve been tinkering with this little project, = I=E2=80=99ve been paying a bit more attention to my overall WiFi = performance and I=E2=80=99m beginning to think there are just too many = WiFi signals nearby and congestion is just killing my overall WiFi = performance. Any other ideas? Thanks, Chris
