DSL bandwidth and cooking my dinner are related?

Whats the correlation between the act of getting my dinner heated and BitTorrent download speeds?

I experienced today something that was rather obvious after taking a look at the frequency spectrum. I was rather amused to see two of my laptops suddenly experience some sort of simultaneous network connectivity problems. In one, Azureus was showing a drop on my combined downloaded speeds and in the other the Internet radio I was listening started to break down and buffer repeatedly... I just then realized that had been few minutes since I had started heating some food in the microwave. The kitchen stands about half the way from my living room to the wireless access point and it kind of made sense that the microwave could be the reason. Sure enough, once it was done the speeds peaked up again.

Some reading later on showed that indeed, operating microwaves can impair the signal quality in wireless networks. I just thought that microwaves irradiated much less. On the other hand, probably the signal levels are so low that small inference easily degrades the signal. I found it amusing.

Microwave Owens: 2.450 GHz

US/Canada 802.11b/g Channel Nominal Frequencies go from 2.412 GHz to 2.462 GHz in steps of 5 MHz
(Europe seems to use very similar frequencies if not the same.)
