Linksys wrt54g with HyperWRT cannot telnet wl command

Hi, I am new to telneting to routers, but I need to do it as part of a project.
I have the wrt54g with hyperwrt frimware. I need to telnet in through a wondows command line and use the wl commands.
I can manage to telnet into router, but no wl commands will work. The telnet connection hangs and is non responsive after entering a wl command.
I think that there could be a problem with my configuration setting on the router, but I have no idea where to start. I have been googling for two days with no answers. Any help is greatly appreciated.

Thanks
