The newest build of CeroWrt - 3.10.24-8 - is working quite well for us. There’s a Release Note page that gives the current status. Note that, although it has been very stable, this is still an experimental release. It’s available at http://snapon.lab.bufferbloat.net/~cero2/cerowrt/wndr/3.10.24-8/
The CeroWrt development team has been working to nail down a no-brainer set of instructions for eliminating bufferbloat - the lag/latency that kills voice & video chat, gaming, and overall network responsiveness. The hard part is that optimal configuration of the Smart Queue Management (SQM) link is difficult - there are tons of options an ISP can set. Although CeroWrt can adapt to any of them, it’s difficult to find out the exact characteristics of the link you have.
