新家上网需要一台好点的ADSL路由器，放在弱电箱里，组网为路由器+2个AP，
如果家里是光纤上网的可能需要PON接口的路由器，呵呵。
需要支持命令行调试的企业级路由器，最后由于价格原因，选择了AR207V，600￥。
下面只简述ADSL拨号上网的配置，关于AC+AP设置漫游的配置手册描述比较详细，不列出了。
其实ADSL拨号就是PPPOEOA，具体配置参考手册即可，这里补充手册不全的地方。

首先你的ATM口要激活

拨号如果不成功，可以debug查看，无非就是debug ppp和pppoe
term mo
term debug
debug ppp all
debug ppp lcp interface dialer 1
成功后可以看到dialer接口获取到了地址。
