It is a fascinating topic when we wrestle with what our ears tell us vs what the theory/spec sheet tells us.

FWIW - I agree with the theory both here and in Ronnie's question to HQ via Rick which says it should make no difference (where a router or how many routers are involved).

However, my suspicion is that there IS something here that we (collectively) do not quite understand yet.

I will be sitting on the fence for a while I think until I get time to move a few units around at home.
