Yep.  At least, reliability of the NFS; I've seen it
throw timeouts. :(

Yeah, I forgot to mention, it's running openwrt, so tuning the 802.11
transmit power is no problem.  In fact, openwrt runs it at max power by
default: http://forum.openwrt.org/viewtopic.php?pid=23263

(However consensus in OpenWRT-land seems to be that it won't help that
much, except in the WRT<->WRT WDS case, since it won't affect
transmissions from the clients.)

by the way, having played with DD-WRT, I think I'll probably go for that
next time.  the rodent-driven UI is sometimes quite nice ;)
