Thanks for the feedback and diagnostics. I believe you have something there and I will implement your advise. However, if I just go into hibernation or standby and shut off my WiFi access and/or unplug my hardwire when I'm done computing, then I can totally avoid this issue. Which pretty much proves your diagnosis. The downside, I don't get my updates unless I shutdown and start-up with the noise again ~OR~ seek out my updates manually. Trade-off, six-o-one/half-dozen the other.
It's ALWAYS something...huh? ;p
Salutes and Smiles to ya for your Efforts!
Like your Pink Floyd quote. Dark Side of the Moon fan myself. Yes, we are ALL MAD.
