      <description>好久没有更新路由器的版本，新年正好更新下。
1、检查现有版本 cat /etc/banner #查询现有版本编号  DESIGNATED DRIVER (Bleeding Edge, xxxxx) -- 我用的是snapshots版本，xxxxx为详细版本号
cat /proc/cpuinfo #如果懒得去看路由器，可以直接查询硬件型号  system type : Atheros AR7161 rev 2 machine : NETGEAR WNDR3700/WNDR3800/WNDRMAC 和官网wiki信息对比: https://wiki.openwrt.org/toh/netgear/wndr3700 , 只有v1，v2两个型号。(差别是flash，直接用df命令进行比对，确认为v2版本)
2、下载对应版本及更新 去官网检索对应的固件，ar71xx系列地址: http://downloads.openwrt.org/snapshots/trunk/ar71xx/generic/
cd /tmp #下载固件文件 wget http://downloads.openwrt.org/snapshots/trunk/ar71xx/generic/openwrt-ar71xx-generic-wndr3700v2-squashfs-sysupgrade.bin #下载md5校验文件 wget http://downloads.openwrt.org/snapshots/trunk/ar71xx/generic/md5sums #md5校验 md5sum -c md5sums 2&amp;gt; /dev/null | grep OK  确认文件下载正常就可以刷入固件，因为3700v2的空间和内存足够，直接刷入。(建议使用有线状态刷入)
sysupgrade -v /tmp/openwrt-ar71xx-generic-wndr3700v2-squashfs-sysupgrade.bin  3、更新确认 cat /mnt/banner  _______ ________ __ | |.&amp;mdash;&amp;ndash;.&amp;mdash;&amp;ndash;.&amp;mdash;&amp;ndash;.| | | |.</description>
