我有 Atheros Wi-Fi 设备 (ath9k),路由器是 Dlink DSL-2750B。我已将路由器配置为仅 802.11n,但我没有 300Mb/s。
这是iwconfig
输出

嗯,我只有 90Mb/s,然后是 300 Mb/s。为什么?
输出iwlist

我怎样才能获得像标准 300Mb/s 那样的比特率?
答案1
请尝试以下解决方案:
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
重新启动系统以使设置生效。
