Hi! Obviously that speed was between the router itself and the USB drive, tested with "dd if=/dev/zero of=/mnt/sda1/test.bin bs=1M count=100" , not through the LAN or Wireless.
It was slower when transferring through network, around 5MB/s over the wireless at 4 meters.
Also samba limits the speed pretty much due the cpu load.
You're so active. WOW.
Did you experience TX power penalty like this? Any test, any solution?
