I thought got be the Xmas lights! I connected the Xmas lights using a Belkin surge supressor, and the problem is gone!
This is the puppy I am using ---> http://www.belkin.com/IWCatProductPage. ... _Id=400738 I like it because of this: EMI/RFI Noise Filtration 150kHz ~ 100MHz up to 40 dB reduction ! I don't care about Joule Rating, if the Xmas lights got fried, good! I get new ones!
One of these days I will hook my Oscilloscope to the AC line after taking the necessary precaution, remove a pair of Belkin surge supressor, and share with guys some pictures.
If you are not using Ethernet over power or have no xmas lighs installed, this may not apply to you, but just in case, these are my two cents.
