My problem is when, by default, the 802.11n mode is enabled, the USB dongle's connection speed is only around 1 Mb/s (with both drivers). When I turn it off with "options rtl8192su ht_enable=0" in its config file, I get my full internet speed, about 30 Mb/s. I'm asking whether it's a problem in the firmware or somewhere in the driver code? If it's the latter case and you're interested in, I would like to help debugging the problem and help you to fix this issue. Thank you very much. All the best, Ákos
