Did you set your console to 115000?

Re: 1800 Rommom mode

Hi ,

you are getting junk characters because console baud rate is not matching with that of router.

start checking it by changing baud rate of hyper terminal from min value to max one point you will get rommon mode...

Start from 300...try if u get access ok otherwise disconnect the hyper terminal..

then check with next value....follow the same procedure..

then 1200...then 2400...and so on...til you get console access of router

For each and every you need to disconnect the hyper terminal.

Re: 1800 Rommom mode

It looks like the connection is being made from a commserver of some sort. The commserver needs to be set to the same baud rate as the router for it to function properly. If this is not possible to do you'd need to go onsite and connect directly from a laptop with console cable. The terminal program needs to be the same baud rate as the router
