|I haven't abandoned you kind folks, thanks for your continued support; great information!|
Where I work, we sell the same 6 Way Mains Conditioner that I found on Amazon (That's how I knew of it's existence), the Tacima one. Now this isn't a completely fair test, because I have reshuffled equipment - but only because the new Mains Conditioner allows such a manoeuvre, with an additional 6 sockets.
So I have all my PC equipment on the Mains Conditioner, cables tidied up too. The Lamp & Fan are now on a different Mains Block, so if it is somehow creating anomalies on the mains, they are now hopefully being filtered.
So I activated my Desk lamp about 6 times, and switching my fan on/off about 20 times (including right next to the HDD's to check for the airborne possibility), and it's not caused a single hiccup! No USB HDD's reconnecting, no Homeplug failures.
1) I'm very lucky at the moment
2) The Mains conditioner is doing something good
3) It's merely because I was able to relocate the Fan/Lamp - onto the second Wall socket in fact, off a separate standard Mains Block.
I could further test, by swapping the Mains Conditioner with another regular 6-way block, but it's still not identical conditions compared to before since the Lamp/Fan is moved.
With this new set-up, I would still expect my Homeplugs to fail though because I've kept it off of the Conditioner (under the presumption the Condition will hamper/destroy data connectivity), connected to the block with the Lamp & Fan in fact.
If this set-up ultimately works... I'm wondering if it could just be Mains Interference from the Lamp/Fan being turned on? The cables running past, possibly along side, the PC equipment DC/AC power leads, if that's even possible.
I might still pick up the Mains Wiring tester, it's cheap and can check that all is well; why not. (In fact we always used to sell that as well, but just of recent we have ceased stocking it in store, typical!)
Thanks for all your help Derek, StuartS and Fingers, if I notice the interruptions occurring at all in the next week, I'll be back. (Not so much to trouble you more, more-so to share this mysterious quest for knowledge, hehe).
Edit: Gave you a "Best Answer" Derek, hopefully it's solved and ya deserve it :D
