http://ubuntuforums.org – Hello all, I'm running Kubuntu 12.10, with the D-link DWA-556 network adapter As the title suggests, I'm using the ath9k driver, and the speeds are just abysmal, often less than 100 kbps. I've tried several fixes... and nothing has worked for me. My attempts have been: Code: nick@desktop:~$ cat /sys/module/ath9k/parameters/nohwcrypt 1 nick@desktop:~$ Code: nick@desktop:~$ cat /etc/pm/power.d/wireless #!/bin/sh /sbin/iwconfig wlan0 power off nick@desktop:~$ (This temporarily helped, but not much) Code: nick@desktop:~$ cat /etc/modprobe.d/ath9k.conf optio (Hardware)
