注意，看这里。现在putty连时用ip 192.168.1.188
http://blog.appdevp.com/archives/290
先设置电脑IP 192.168.1.3
路由器上的网络插入电脑，putty登录192.168.1.1
root
输入下面这些信息：
设置lan ip(即访问路由的ip，与一级路由不同网段)
uci set network.lan.ipaddr=192.168.2.1
设置wan口类型为静态
uci set network.wan.proto=static
设置wan ip
uci set network.wan.ipaddr=192.168.1.200
网关指向上级路由
uci set network.wan.gateway=192.168.1.1
dns指向上级路由
uci set network.wan.dns=192.168.1.1
2.配置无线网络
打开无线
uci set wireless.@wifi-device[0].disabled=0
设置功率为17dbm
uci set wireless.@wifi-device[0].txpower=17
设置无线信道为8
uci set wireless.@wifi-device[0].channel=8
设置无线模式为ap
uci set wireless.@wifi-iface[0].mode=ap
设置无线SSID
uci set wireless.@wifi-iface[0].ssid=xxxxxx
无线链接到lan上
uci set wireless.@wifi-iface[0].network=lan
设置加密为WPA2-PSK
uci set wireless.@wifi-iface[0].encryption=psk2
设置无线密码
uci set wireless.@wifi-iface[0].key=kf42
————————————————————————-
3.应用配置：
应用提交
uci commit
重新启动网络
/etc/init.d/network restart
————————————————————————-
将电脑上的网线和路由器拔下来，插到另外的上级路由器上。重启，路由器就会显示xxxxx的wifi信号了
电脑连上xxxxx，ip改成192.168.2.3，用putty就可以登录192.168.2.1了。
我连上后，改vi /etc/config/network 192.168.2.1 改成192.168.1.188 本电脑改回自动ip，ssh 192.168.1.188也可以
config interface 'loopback'
option ifname 'lo'
option proto 'static'
option ipaddr '127.0.0.1'
option netmask '255.0.0.0'
config globals 'globals'
option ula_prefix 'fd36:f77a:1bcd::/48'
config interface 'lan'
option type 'bridge'
option ifname 'eth0'
option proto 'static'
option netmask '255.255.255.0'
option ip6assign '60'
option ipaddr '192.168.1.188'
~
在文件/etc/config/dhcp应该有一段是这样子的：
config 'dhcp' 'lan'
option 'interface' 'lan'
option 'start' '100'
option 'limit' '150'
option 'leasetime' '12h'
list 'dhcp_option' '6,87.216.1.65,87.216.1.66'
之前一直上不了网，终于找到原因了：
ping www.baidu.com ping不通
ping 119.75.217.56 显示：ping: sendto: Network unreachable
百度一下找到：
在我的板子上ping路由上的IP的时候可以ping通，但是ping外网的IP的时候提示“ping: sendto: Network is unreachable”
后来使用route命令看了一下
# route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.0 * 255.255.255.0 U 0 0 0 rausb0
发现网关（Gateway），是空着的没有设置，于是执行一下命令设置了网关：
# route add default gw 192.168.1.1
# route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.0 * 255.255.255.0 U 0 0 0 rausb0
default 192.168.1.1 0.0.0.0 UG 0 0 0 rausb0
最后终于可以ping通外网了
# ping 119.75.217.56
PING 119.75.217.56 (119.75.217.56): 56 data bytes
64 bytes from 119.75.217.56: seq=0 ttl=52 time=38.349 ms
64 bytes from 119.75.217.56: seq=1 ttl=52 time=30.369 ms
64 bytes from 119.75.217.56: seq=2 ttl=52 time=30.541 ms
64 bytes from 119.75.217.56: seq=3 ttl=52 time=29.659 ms
64 bytes from 119.75.217.56: seq=4 ttl=52 time=29.786 ms
另外如果网络的其他信息没有设置好，也会出现这样的情况，可以参考如下设置（http://www.lslnet.com/linux/f/docs1/i57/big5378732.htm）
ifconfig lo 127.0.0.1
route add -net 127.0.0.0 netmask 255.255.255.0 lo
ifconfig eth0 192.168.10.0
route add -net 192.168.10.0 netmask 255.255.255.0
试了一下，终于可以了
已经装了：
opkg install mjpg-streamer
telnet 192.168.1.1
一。让设备联网
1.1 pppoe用户：
设置wan口类型为pppoe
uci set network.wan.proto=pppoe
设置pppoe用户名和密码、mtu
uci set network.wan.username=xxxxx
uci set network.wan.password=xxxxxx
uci set network.wan.mtu=1492
1.2二级路由模式（非DHCP获取）：
设置lan ip(即访问路由的ip，与一级路由不同网段)
uci set network.lan.ipaddr=192.168.2.1
设置wan口类型为静态
uci set network.wan.proto=static
设置wan ip
uci set network.wan.ipaddr=192.168.1.200
网关指向上级路由
uci set network.wan.gateway=192.168.1.1
dns指向上级路由
uci set network.wan.dns=192.168.1.1
1.3交换机模式（当交换机用，WAN口空置）
关掉wan
uci set network.wan.proto=none
设置lan ip（本路由登陆IP）
uci set network.lan.ipaddr=192.168.1.100
网关指向上级路由
uci set network.lan.gateway=192.168.1.1
dns指向上级路由
uci set network.lan.dns=192.168.1.1
关掉lan的dhcp
uci set dhcp.lan.ignore=1
2.配置无线
打开无线
uci set wireless.@wifi-device[0].disabled=0
设置功率为17dbm 太高会烧无线模块
uci set wireless.@wifi-device[0].txpower=17
设置无线信道为8
uci set wireless.@wifi-device[0].channel=8
以下2行是开启300M
uci set wireless.@wifi-device[0].htmode=HT40-
uci set wireless.@wifi-device[0].noscan=1
设置无线模式为ap
uci set wireless.@wifi-iface[0].mode=ap
设置无线SSID
uci set wireless.@wifi-iface[0].ssid=xxxxxx
无线链接到lan上
uci set wireless.@wifi-iface[0].network=lan
设置加密为WPA2-PSK
uci set wireless.@wifi-iface[0].encryption=psk2
设置无线密码
uci set wireless.@wifi-iface[0].key=xxxxx
3.最后应用配置：
应用
uci commit
重新启动网络
/etc/init.d/network restart
二。安装组件
查看已安装的组件包
opkg list-installed
更新组件包package
opkg update
安装luci的web配置界面
opkg install luci
启动uhttpd服务
/etc/init.d/uhttpd enable
/etc/init.d/uhttpd start
这时，在浏览器打开192.168.1.1（如果没修改过）进入web配置界面
本地源设置：

一次替换文件里的内容：
sed -i 's/jsl.openwrt.bobiji.com/aqb.openwrt.bobiji.com/g' /etc/opkg.conf
sed -i 's/aqb.openwrt.bobiji.com/openwrt.mrx.one/g' /etc/opkg.conf
sed -i 's/openwrt.mrx.one/jsl.openwrt.bobiji.com/g' /etc/opkg.conf
sed -i 's/jsl.openwrt.bobiji.com/openwrt.mrx.one/g' /etc/opkg.conf
df -h 查看空间
记一下如何好使的：
一定要先设置wifi后安装下面这些，不然没空间！！！就设置不了wifi了，没空间写不进数据了
http://www.znck007.com/forum.php?mod=viewthread&tid=21570
我刷了openwrt， 不好使，后来在openwrt下，用命令
mtd -r write xxxx.bin firmware 重新装了openwrt-ar71xx-generic-tl-mr13u-v1-squashfs-factory.bin
路由器网络 连接插入电脑，打开网页，直接就可以192.168.1.1了，设置wifi（上面的链接）
putty连上后
opkg update
opkg install kmod-video-uvc 只装这2个就能显示图像
opkg install mjpg-streamer 只装这2个就能显示图像
opkg install ser2net 引出rx tx ttl
opkg install kmod-video-pwc 不装，浪费空间
opkg install kmod-usb-ohci 不装，浪费空间
ls /dev 怎么都不显示/video0,硬重启了一下路由后，再打这个命令就看到video0了。
按这个设置的
http://tieba.baidu.com/p/2565884424
http://www.right.com.cn/forum/thread-76305-1-1.html
不用装什么驱动
mjpg_streamer -i "input_uvc.so -r 640x480 -f 30" -o "output_http.so -p 8080 -w /www"
192.168.0.2:8080/?action=stream（动态视频）

opkg list_installed命令查看安装程序的列表
opkg remove+程序名称卸载
将不是必须的程序删掉就行了
恢复路由默认设置：
System->Backup /Flash Firmware -> Perform reset
恢复后设置 wifi:
network -> wifi -> Scan -> 选择你的wifi -> join network -> 输入密码->submit
network -> wifi -> Add -> Interface Configuration -> ESSID输入要生成的wifi名 xxxCar，选择lan -> Wireless Security设置 WPA-PSK/WPA2-PSK Mixed -> Key输入要设置的密码
到这里就可以上网了，可以看到xxxCar wifi了
到System -> Administration里设置putty要登录的账号密码，root + 密码
在System -> Software可以查看到剩下的空间
在network -> interface -> LAN -> Edit -> DHCP Server -> Advanced Settings -> 勾选 Dynamic DHCP 和 Force 并在DHCP-Options里输入3,192.168.10.1 这样使用xxxCar wifi的设备会自动分配IP，IP为192.168.10.x
ttl刷机：
我的路由器上的线，黄色连接usb2ttl上的gdn，红色接txd，蓝色接rxd (蓝色线在焊点模块的内侧，红色在外)
usb2ttl需要安装驱动
插入网线，设置本地链接：192.168.1.100 255.255.255.0 192.168.1.1
打开secureCRT,看usb2tll的com是几
Serial
COM4
115200
取消RTS/CTS
连接，打开View->Char window，输入tpl，然后 打开路由器开关，当出现Autobooting in 1 seconds的时候，按回车执行tpl命令进入安全模式，这里绝对要掌握好时间

发现网关（Gateway），是空着的没有设置，于是执行一下命令设置了网关：
# route add default gw 192.168.1.1
# route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.0 * 255.255.255.0 U 0 0 0 rausb0
default 192.168.1.1 0.0.0.0 UG 0 0 0 rausb0
最后终于可以ping通外网了
# ping 119.75.217.56
PING 119.75.217.56 (119.75.217.56): 56 data bytes

64 bytes from 119.75.217.56: seq=4 ttl=52 time=29.786 ms
另外如果网络的其他信息没有设置好，也会出现这样的情况，可以参考如下设置（http://www.lslnet.com/linux/f/docs1/i57/big5378732.htm）
ifconfig lo 127.0.0.1
route add -net 127.0.0.0 netmask 255.255.255.0 lo
ifconfig eth0 192.168.10.0
route add -net 192.168.10.0 netmask 255.255.255.0
试了一下，终于可以了
已经装了：
opkg install mjpg-streamer
telnet 192.168.1.1
一。让设备联网
1.1 pppoe用户：
设置wan口类型为pppoe
uci set network.wan.proto=pppoe
设置pppoe用户名和密码、mtu
uci set network.wan.username=xxxxx
uci set network.wan.password=xxxxxx
uci set network.wan.mtu=1492
1.2二级路由模式（非DHCP获取）：
设置lan ip(即访问路由的ip，与一级路由不同网段)
uci set network.lan.ipaddr=192.168.2.1
设置wan口类型为静态
uci set network.wan.proto=static
设置wan ip
uci set network.wan.ipaddr=192.168.1.200
网关指向上级路由
uci set network.wan.gateway=192.168.1.1
dns指向上级路由
uci set network.wan.dns=192.168.1.1
1.3交换机模式（当交换机用，WAN口空置）
关掉wan
uci set network.wan.proto=none
设置lan ip（本路由登陆IP）
uci set network.lan.ipaddr=192.168.1.100
网关指向上级路由
uci set network.lan.gateway=192.168.1.1
dns指向上级路由
uci set network.lan.dns=192.168.1.1
关掉lan的dhcp
uci set dhcp.lan.ignore=1
2.配置无线
打开无线
uci set wireless.@wifi-device[0].disabled=0
设置功率为17dbm 太高会烧无线模块
uci set wireless.@wifi-device[0].txpower=17
设置无线信道为8
uci set wireless.@wifi-device[0].channel=8
以下2行是开启300M
uci set wireless.@wifi-device[0].htmode=HT40-
uci set wireless.@wifi-device[0].noscan=1
设置无线模式为ap
uci set wireless.@wifi-iface[0].mode=ap
设置无线SSID
uci set wireless.@wifi-iface[0].ssid=xxxxxx
无线链接到lan上
uci set wireless.@wifi-iface[0].network=lan
设置加密为WPA2-PSK
uci set wireless.@wifi-iface[0].encryption=psk2
设置无线密码
uci set wireless.@wifi-iface[0].key=xxxxx
3.最后应用配置：
应用
uci commit
重新启动网络
/etc/init.d/network restart
二。安装组件
查看已安装的组件包
opkg list-installed
更新组件包package
opkg update
安装luci的web配置界面
opkg install luci
启动uhttpd服务
/etc/init.d/uhttpd enable
/etc/init.d/uhttpd start
这时，在浏览器打开192.168.1.1（如果没修改过）进入web配置界面
本地源设置：
vi ect/opkg.conf
dest root /
dest ram /tmp
lists_dir ext /var/opkg-lists
option overlay_root /overlay

一次替换文件里的内容：
sed -i 's/jsl.openwrt.bobiji.com/aqb.openwrt.bobiji.com/g' /etc/opkg.conf
sed -i 's/aqb.openwrt.bobiji.com/openwrt.mrx.one/g' /etc/opkg.conf
sed -i 's/openwrt.mrx.one/jsl.openwrt.bobiji.com/g' /etc/opkg.conf
sed -i 's/jsl.openwrt.bobiji.com/openwrt.mrx.one/g' /etc/opkg.conf
df -h 查看空间
记一下如何好使的：
一定要先设置wifi后安装下面这些，不然没空间！！！就设置不了wifi了，没空间写不进数据了
http://www.znck007.com/forum.php?mod=viewthread&tid=21570
我刷了openwrt， 不好使，后来在openwrt下，用命令
mtd -r write xxxx.bin firmware 重新装了openwrt-ar71xx-generic-tl-mr13u-v1-squashfs-factory.bin
路由器网络 连接插入电脑，打开网页，直接就可以192.168.1.1了，设置wifi（上面的链接）
putty连上后
opkg update
opkg install kmod-video-uvc 只装这2个就能显示图像
opkg install mjpg-streamer 只装这2个就能显示图像
opkg install ser2net 引出rx tx ttl
opkg install kmod-video-pwc 不装，浪费空间
opkg install kmod-usb-ohci 不装，浪费空间
ls /dev 怎么都不显示/video0,硬重启了一下路由后，再打这个命令就看到video0了。
按这个设置的

不用装什么驱动
mjpg_streamer -i "input_uvc.so -r 640x480 -f 30" -o "output_http.so -p 8080 -w /www"
192.168.0.2:8080/?action=stream（动态视频）

opkg list_installed命令查看安装程序的列表
opkg remove+程序名称卸载
将不是必须的程序删掉就行了
恢复路由默认设置：
System->Backup /Flash Firmware -> Perform reset
恢复后设置 wifi:
network -> wifi -> Scan -> 选择你的wifi -> join network -> 输入密码->submit
network -> wifi -> Add -> Interface Configuration -> ESSID输入要生成的wifi名 xxxCar，选择lan -> Wireless Security设置 WPA-PSK/WPA2-PSK Mixed -> Key输入要设置的密码
到这里就可以上网了，可以看到xxxCar wifi了
到System -> Administration里设置putty要登录的账号密码，root + 密码
在System -> Software可以查看到剩下的空间
在network -> interface -> LAN -> Edit -> DHCP Server -> Advanced Settings -> 勾选 Dynamic DHCP 和 Force 并在DHCP-Options里输入3,192.168.10.1 这样使用xxxCar wifi的设备会自动分配IP，IP为192.168.10.x
ttl刷机：
我的路由器上的线，黄色连接usb2ttl上的gdn，红色接txd，蓝色接rxd (蓝色线在焊点模块的内侧，红色在外)
usb2ttl需要安装驱动
插入网线，设置本地链接：192.168.1.100 255.255.255.0 192.168.1.1
打开secureCRT,看usb2tll的com是几
Serial
COM4
115200
取消RTS/CTS
连接，打开View->Char window，输入tpl，然后 打开路由器开关，当出现Autobooting in 1 seconds的时候，按回车执行tpl命令进入安全模式，这里绝对要掌握好时间

之后，就可以直接打开192.168.1.1，看到页面了
外网访问时，要把openwrt里，防火墙全部改成aceept
可以加密码。
修改/etc/init.d/mjpg-streamer文件
start函数里面，增加：
config_get username core username
config_get password core password
