WL-500gP Hidden Admin Page

The official Asus firmware for the Asus WL-500g Premium wireless router does not support telnet'ing into the router. Other firmware versions, like Oleg's, DD-WRT and OpenWRT does. Without telnet (or SSH) support, it is impossible to mess with tweaks and fine tunings, since these are not available through the web interface, but can only be executed from a command line. This is probably the reason why Asus has equipped the WL-500gP (and other router models) with a hidden admin page that works like a router command line.

This hidden admin page is just a web page with a textfield for issuing commands, a text area for displaying command output and a button for executing commands. You'll find the hidden admin page at: http://$ROUTER_IP/Main_AdmStatus_Content.asp (replace $ROUTER_IP with the actual IP address of your router - if you have not changed the default setting, the IP is As far as I know, the hidden admin page is not mentioned in any of the official WL-500gP documentation.

Since this admin page is basically undocumented, you have to piece together how to use if from forum posts etc. By browsing the wl500g.info forum, I discovered that executing the command 'wl cmds' will output a list of available commands: Type in 'wl cmds' in the textfield and click the "Refresh" to display the list. It's a rather long list and there are no descriptions of the commands, so it is difficult to know how to use them.

Executing the command 'wl -h' will output some help. - No, it won't!

Besides the 'wl' commands, it is also possible to execute basic Linux commands. For instance, memory (RAM) usage can be checked by typing in cat /proc/meminfo and press "Refresh":
