带有ath9k的802.11n：仅为90 Mb / s

我有用于Wi-Fi的Atheros设备（ath9k），路由器是Dlink DSL-2750B。 我只为802.11n配置了路由器，但我没有300Mb / s。

这是iwconfig输出

  wlan0 IEEE 802.11bgn ESSID:"Skynet" Mode:Managed Frequency:2.437 GHz Access Point: EC:22:80:E7:12:C5 Bit Rate=90 Mb/s Tx-Power=15 dBm Retry short limit:7 RTS thr:off Fragment thr:off Power Management:off Link Quality=51/70 Signal level=-59 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:1 Invalid misc:1506 Missed beacon:0 

好吧，我只有90Mb / s然后300 Mb / s。 为什么？

iwlist输出是

如何获得标准300Mb / s的比特率？

Answer 1

尝试以下解决方案：
sudo -i echo "options ath9k nohwcrypt=1 ps_enable=1" >> /etc/modprobe.d/ath9k.conf modprobe -r ath9k modprobe ath9k nohwcrypt=1 modprobe ath9k ps_enable=1

重新启动系统以使其生效。
