I've got a brand new, unopened Belkin N600 DB router (yay 50% off sale), and I can't seem to figure out if I can use it as a repeater. As far as I can tell, it doesn't support DD-WRT or Tomato, but I'm wondering if there may be some way to rig it up to repeat Wifi. Also, I really need to know before I open it, because, being a bit tight on money at the moment, I'll probably sell it if I can't use it as a repeater.

Finally, two caveats:

• I can't use the other wireless router for anything other than broadcasting straight from the modem (parents are paranoid about anything technological).
• I can't run ethernet to the second router due to the layout of the house.

Thanks so much for the help everyone--if I'm being vague, tell me!

EDIT: Also, the manual here is pretty useless on this topic as far as I can tell.
