custom firmware for DL-614+

[zimu]

I have a dlink 614+ wireless router (model 1- with 2 antennae), and was wondering if there is some custom firmware apart from that provided from dlink that i could upload onto it, which may give it some cool additional features?

anybody know of anything, or have the same router and have other firmware on it?

i currently have version 2.20cr on it, the one provided by dlink.

thanks!
