Crestron is currently sitting on a firmware update that solves the ethernet socket problems that causes restarts. Unfortunately they have not deemed it important enough to release to the public. I have a copy of it after making a stink to get the problem fixed. This stabilizes the ethernet on all 2 series processors, allowing it to be used as intended.
Ask your rep for FW: 4.0007.0022+, 4.0007.0022 is the first firmware with the known fix implemented. Normally I would not resort to this, but as it will help many of the ethernet control problems, i figure you all should have a chance to try it.
