Thanks. That helps. I've decided there's something funky with that particular wireless router's wireless that's causing the problem. I've now got a different non-wireless router installed; everything works fine when I go directly through it via Ethernet cable; I'm just using the wireless part of the WRT350N as an AP; I'm getting the same problems as soon as I go through it. And I don't seem to have the problems going through other wireless systems.
