Here's some of my short experience using this router:
3.13.5 Firmware
V1.8 Hardware.
Streamyx 1.0mbps

1. Router will hang after 4-5 hours of torrenting. I'm just doing very mild torrenting of 1 torrent at a time, limited to 150 connections per torrent.

2. Download and upgraded to 3.13.12 from website. At first would run even 12hours of torrenting but eventually would hang after maybe 6 hours.

3. Got the latest DD-wrt and flashed it in webui. Now been running for about 24hrs of torrenting without any hiccup. So far so good. Anyway plan to do a reset every 3hrs with DD WRT if it still occurs.

Speeds via Wifi can reach 10MB/s when connected via 300mbps at 10ft. (Using Intel Centrino 6300N card). Not sure I should be happy or not.

Range seems about 3-4 feet further than my oldie WRT54G v7. I'd put my WRT54G at at about 15 feet direct but with 2-3 walls.

Slightly stronger signal at the tail end of the reach also.

Wired connections can reach 30-35MB/s which is kinda expected with my dated hardware but all with Gigabit LAN.

So I'd very much encourage anyone running heavy P2P to give DD-WRT a try.
