I have a few hard to get locations for voip. Wireless is an option but it is bulky and requires wall power for the phone. There is plenty of old 50 pair phone cable. I took the first four pair from one cable and patched it into a POE switch. Instant power but no ethernet. I changed the switch port to 10mb and it works!!! Of course I will not be using this for data because of the 10mb limit.

After killing the NetAuthAgent application, everything works well again:
