I've tried the module in several outlets (including using an extension cord to get to a far away outlet). I also tried using a brand new USB cable as well. Is this just a bad module? It seems too coincidental that the previous poster also had the issue on a Mac Pro.
Given that the Mac Pro is one of only a few Macs available, not a very unusual coincidence at all. If you've tried all the things on the above referenced signal troubleshooting page, you might try factory resetting the PowerLinc as well. If that doesn't work, then its most likely a bad PowerLinc (I had one of my testing units go out just last week - and it's not very old).
