②、用show命令显示当前默认参数，记下可用的VPI/VCI等配置信息，为下一步配置做预备。
>> show
Ethernet ip: 192.168.1.1
Subnet mask: 255.255.255.0
FullDuplex:Disable
FUNCTION VPI/VCI CLASS LLC/VCMUX Spanning Pkt Filter
Rfc1483 8/35 ubr LLC Disable ANY
Rfc1483 8/81 ubr LLC Disable ANY
Rfc1483 0/35 ubr LLC Disable ANY
Rfc1483 0/32 ubr LLC Disable ANY
Rfc1483 1/33 ubr LLC Disable ANY
③、用mode命令选择路由工作模式，原默认的是Bridge方式。
>> mode
Please select bridge or router:(b/r,b)r
Current mode is router
④、进入r1483子菜单，删除原配置参数。
>> r1483
> r1483> delwanip all
> r1483> home
⑤、用quick命令配置路由工作参数，其中VPI/VCI的数值可填入原配置参数，如最仍不能上网，则换一对数值再配，必有一种合适。User name/PassWord就是电信局指定的用户名及口令。
