So if the problem with the 10/100 switches is not the data transfer rate, then what is it? Seems to me that if it works at 10 Mbps and doesn't at 100, then the receiver must start to have trouble at some rate in between 10 and 100.


The Rio Receiver works only at 10Mbps.

The problem is that, when you connect a network cable to an Ethernet switch, the two ends negotiate a speed, whether they should use duplex, and (sometimes) the switch auto-senses whether you've got a normal or crossover cable plugged in.

You can see the effect of this: when you plug the cable in, it sometimes takes a fraction of a second before the link light comes on.

Where the problem lies is that the network hardware in the Rio Receiver is not very forgiving of network hardware that's a little bit out of spec.

If it takes too long to do the negotiation thing, the Rio Receiver decides that you've got no Ethernet plugged in, and switches to using the HPNA socket instead.

You can usually fix this by using a 10Mbps hub (where none of this negotiation happens, so there's no timeout). Alternatively, most Netgear stuff works fine (we had a bunch of Netgear DS108 and FS108 switches at empeg Towers).
