[Bruce Schroeder]

And have you tried a known working Ethernet patch cable?

I've been using HaikuHelper on my Mac as a "push notification gateway" to the Haiku app on my phone, and it seemed to have been working fine. Recently though, I've noticed that the OP2 has become unresponsive on my local network, resulting in repeated disconnect / reconnect events from HaikuHelper.

A quick search didn't reveal any information about the capabilities of the Ethernet port. Is 10/Half all that can be expected? Does auto-negotiation work reliably with the OmniPro II, or should the port be forced?
