I have a very similar issue - I have two PCs linked to it wirelessly - and both have a bridged connection to VOIP phones which are not exactly under heavy use, but along with up to four VPNs being run I don't think this thing was designed for this kind of abuse. I get dropped from my router regularly, which then vanishes from my view entirely. I'm sure it's great for a laptop with no added complication other than Netflix or some such - but those of us who have heavy IP demands with a lot of random traffic, this is just not the tool to use.
I am thinking in order to be actually effective, this would need a 2nd or 3rd unit to make use of the WDS mode and link the added paraphernalia over ethernet, but again - I'm not sure if I want to drop the $ on this unit or go with something more tried and true that also has WDS capability.
