Beware of Electric Blankets - They sap your Wi-Fis, all of them

Just heard this story from a lady about a 2-month long quest to figure out why her iPad worked fine everywhere in her flat except in bed. If she walks over to her window, to the door etc, no problems. But as soon as she lies in bed, no singal.

Anyway, it turns out that electric blankets (specifically, earthed) can sap Wi-Fi signal very well. So she eventually discovered she had to fully unplug the blanket to resolve the problem.

Anyway, I didnt know, and found it useful, so here it is for you all.

iPad (All models), iOS 4

Maybe, just I thought for a Faraday cage effect, the device really needs to be completely enclosed by the cage, not just partially in line-of-sight of it.

So, will we be safe if we wrap ourselves in a Faraday cage blanket? Or is tinfoil still state of the art for this sort of thing?

Tinfoil, absolutely! But make sure to cover your head. That's where the tenticles slither in.

How about an electric blanket wifi hotspot?

That would make for a new wave of insomnia TV informercials!!
