解决openwrt WiFi速率问题 WiFi下载限速提升到11mbps
修改ap设置，带宽20mhz，高级设置中无线信号覆盖密度设为正常，底部关闭wmn

sleep 15
/etc/init.d/network restart
uci set wireless.default_radio0.wmm=1
wifi up
sleep 10
date -s "`mmcli -m 0 --time|grep -E "Time " | awk -F " " '{print $5,$NF}'|awk -F "+" '{print $1,$3}'|awk -F "T" '{print $1,$2}'| awk '{gsub(/^\s+|\s+$/, "");print}'`"
