DD-WRT vs Factory default ROM on D-link DIR-880L

I bought D-Link DIR-880L last year. One of the features of it is DD-WRT compatible.

Three weeks ago, I downloaded the dd-wrt firmware and flashed it on the router.

The version I downloaded is DD-WRT v3.0-r30432 std.

Based on the forum, it said 30432 is the working version for DIR-880L.
