you don't need modem mode etc. you can can do it over wifi.
login via telnet, (Default user: MSO, Default pass: changeme)
type,
cd /
routeShow
scroll up a bit and there will be a table, the first mac will be marked as UHCL, thats your mac, make a note of the ip address to the left of it.
ie, 10.157.17.86 -- 00:11:22:33:44:55 -- UHCL
then type,
cd ping
ip_sweep 255.255.255.0 10.157.17.86 (change the ip to yours, but make the end number 1 ie, 10.157.17.1)
then it will check that range up to 10.157.17.255
once its done you can go up a range 10.157.18.1 etc.
once your finished and you want the list of found macs,
type
cd /
routeShow
then scroll up, there is your list, copy and paste to notepad
