I want to add a MSS value to my ADSL ROUTER. But It looked like making a mistake by myself. Now I have
some problems with my ADSL ROUTER. And the ADSL ROUTER dosn't work any more.

I use 'ip' command to add a MSS value to my ADSL ROUTER.

First, I run this command
xx.xxx.xxx.xx> ip tcpclamp add ppp_device1 mss 1452

and I got a error message
ip: tcpclamp - device "ppp_device1" has not been defined

then, I run this command
xx.xxx.xxx.xx> ip tcpclamp add 1 mss 1452

and I got a error message again
ip: tcpclamp - device "1" has not been defined

Third, I run this command
xx.xxx.xxx.xx> ip tcpclamp add ppp_device 1 mss 1452

I got a error message again
ip: tcpclamp - syntax error in "add ppp_device 1 mss 1452"

Last, I run the command
xx.xxx.xxx.xx> ip tcpclamp add ppp_device mss 1452

Nothing displayed.

I thank it may be succeed. I want to save the config. But I didn't know how to do. So I run 'help' command
to see which command I can use. But it too simple. I choose the 'save-cust' command. After I entered
'save-cust' command, it displayed "Updating flash filing system ...". And all of the LED light of MODEM
turn light.
After waitting a long time, I exit telnet. It haven't any change. So I press the 'reset' switch. But
it still haven't any change. Then I turned off power and waitted a while. Then turned on power. But
now, the "POWER","Line" and "PC" turn on, others turn off. And my ADSL ROUTER doesn't work anymore.

Could anyone can tell me how to fix it? Thanks a lot!
