Sounds like this could be a speed/duplex mismatch. Can you confirm speed/duplex? I tend to force things to 100/full just to be on the safe side.

Thanks for this. But I don't think that can be it.
A duplex mismatch would only manifest itself at high transmission rates (which can make it difficult to diagnose). The sort of traffic I am generating in a simple ping test should not cause any difficulty and I should not get the ICMP "host unreachable" response. (And forcing 100/full would defeat the purpose of autonegotiation and might actually cause later problems when a device tries to autonegotiate with the fixed device).
I can't do anything about the switch settings anyway. The Asus is a home DSL device with an umanaged switch in it. It is designed to be plug and play for any home user. I have just changed the OS.
So - have I just got a duff switch in the Asus (and if so, why the hell does it work when I connect another switch)? Or should I be looking for something else?
Maybe the switch you used to test is better at autonegotiating speed and duplex then your other kit? Don't give up yet! :)
Oh, I'm not about to give up! I've got bugger all else to do on wet bank holiday sunday.
