查看分配的DHCP客户端IP：

cat /tmp/dhcp.leases

扫描无线路由器/AP：

iwinfo wlan0 scan

查看Openwrt路由无线信息：

iwinfo wlan0 infowlan0     ESSID: "OpenWrt"          Access Point: 00:1F:A3:65:55:8E          Mode: Master  Channel: 5 (2.432 GHz)          Tx-Power: 20 dBm  Link Quality: 30/70          Signal: -80 dBm  Noise: unknown          Bit Rate: 32.5 MBit/s          Encryption: WPA2 PSK (CCMP)          Type: nl80211  HW Mode(s): 802.11bg          Hardware: unknown [Generic MAC80211]          TX power offset: unknown          Frequency offset: unknown          Supports VAPs: no  PHY name: phy0

重启无线：

wifi down && sleep 5 && wifi

一个bash脚本，输出当前无线客户端IP/MAC/名称/速率：

#!/bin/bashecho -e "# IP address\tname\tMAC address\ttx bit\trx bit"for interface in `iw dev | grep Interface | cut -f 2 -s -d" "`do  maclist=(`iw dev $interface station dump | grep Station | cut -f 2 -s -d" "`)  txlist=(`iw dev wlan0 station dump|grep 'tx bitrate'|awk '{print $3$4}'`)  rxlist=(`iw dev wlan0 station dump|grep 'rx bitrate'|awk '{print $3$4}'`)  len=${#maclist[@]}  for ((i=0;i<$len;i++))  do    mac=${maclist[$i]}    tx=${txlist[$i]}    rx=${rxlist[$i]}    ip="UNKN"    host=""    ip=`cat /tmp/dhcp.leases | cut -f 2,3,4 -s -d" " | grep $mac | cut -f 2 -s -d" "`    host=`cat /tmp/dhcp.leases | cut -f 2,3,4 -s -d" " | grep $mac | cut -f 3 -s -d" "`    echo -e "$ip\t$host\t$mac\t$tx\t$rx"|awk '{printf "%-15s %-25s %-15s %-10s %-10s\n",$1,$2,$3,$4,$5}'  donedone
