I'm running cerowrt on day-to-day basis on my wndr3800 for quite a while
and it works like a charm. It is rc7-smoketest10 build. Managed to
configure everything I needed apart from dyndns client which is not a big
So far wndr3800+cerowrt is the best performer out of many routers I tried.
I tested wndr3800 stock, linksys e3000 and e4200 with stock and tomatousb,
pfsense 2.0 appliance, cradlepoint mbr1400 and some others. Speedtest on
wndr3800+cerowrt is constantly at or almost at the top of the list and
during the speed test ping times are not deteriorating as badly as for the
other routers. Feature-wise cerowrt is also the best (for my particular
setup), so currently it is my main router at home even though initially I
bought it for playing and testing.
I've just received another wndr3800 and going to install openwrt on it to
compare them side-by-side and to have a playground for routers.
Overall, excellent job, Dave! I'm keeping my eye on cerowrt.
