Kind friends...
I offer this in hopes that someone will find it useful or interesting - 'Entertaining' is ok too inasmuch as I'm a 'happy camper' now my longstanding problem is solved...
So... For over a year I've been experiencing difficulties with my home wireless network despite recourse to a large variety of routers, after-market antennae, external amplifiers, etc...
Today I got a 'break' when my housekeeper inquired as to why an 'unplugged' florescent 'work lamp' flickered whenever she heated her coffee -- The below attached image neatly answers her question and explains my problem
Despite the existence of a 'second bottom' fashioned of a louvered and otherwise perforated piece of sheet steel - the leakage manifested as a prominent 'lobe' extending from the front and right of the appliance and registering as 'excessive' (CIP 'pegged' at > 10mW/cm^2) upon a certified 'microwave oven survey meter' to a distance of some 12 feet (said instrument being an intentionally rather 'deaf' passive field strength indicator)...
Four "takeaways":
1) Despite what passes for 'conventional wisdom', magnetrons operating on "ISM 7" (Fc= 2.450 GHz) can and do disrupt digital networks operating on the same band - and, I might add, at considerable distance (to over 400 yards)...
2) While the 'swept' nature of the 'signal' issuing from leaky RF heating devices equipped with conventional PSUs (i.e. magnetic transformer+doubler) does not preclude interference with digital communications equipment, it essentially 'masks' itself from 'standard' UHF/SHF 'fox hunting' gear
3) Should you choose to employ on-premises staff, you may save yourself a great deal of agro (to say nothing of fire insurance premiums) via provision of furnished quarters (with emphasis upon appliances).
4) Whoever 'Emerson' is they (To render John Cleese), deserve a 'thorough, rollicking spanking'
Now I've several trenchers of crow awaiting my 'attentions' on multiple (especially) D-link review fora
OBTW -- To any readers from the 'old country' (UK) -- Please investigate the phrase 'happy camper' as apparent in American slang prior to drawing conclusions!
Best regards
