You need to install Entware, so you can subsequently install the tcpdump package(s). Since you're using a router w/ Atheros chipset, you need an Atheros compability version of Entware. I found the following thread, which may prove helpful.
It will probably require a special DD-WRT build though. At which point, better to use OpenWRT. _________________ Before asking a question on the forums, update dd-wrt: Where do I download firmware? I suggest reading it all.
Some dd-wrt wiki pages are up to date, others are not. PM me if you find an old one, I am trying to update them.

Old is also your router.
If you are really interested in adding additional functions then make sure your basic hardware supports it.
