I own D-Link WBR-1310 RevB. This router is frankly a pain in the ass.

I get dropped connections so many times, and god is it an annoyance. If I'm playing online, fort forwarding on this thing is such a pain, not just the latency gap. Same for when I'm watching Netflix. I've seen threads online about flashing other firmwares onto the RevA version, but I tried following this guide: http://forums.dlink.com/index.php?topic=11132.0 and it didn't work for my RevB. Is there anything out there for RevB? Tomato firmware, anything?
Thank you.
