I have a Linksys WRT-160N V3 for about a year and installed dd-wrt on it, I had some problems with 'N' dropping connections and a very strange problem where rebotting a W7 laptop made the XP one disconnecting (see here).
I never used Tomato, only heard about it, so I read the how-to then installed it on my router (taking care of the password and resetting the nvram and all), and now my problems dissapeared!
So I'm just sharing my experience with you to thank the developers for their work :)
