A spark gap (aka noise jammer) is laughably broad and would also cause interference with everyone in the neighbourhood. But a frequency selective Wifi noise jammer is very effective, especially if aimed at the base station with a directional antenna.
I wouldn't recommend disassembling a microwave oven to get at its magnetron, because you will probably electrocute yourself at best, and if you manage to turn it on (e.g. by jamming the door closed sensors), literally cooking your eyeballs.
- bigiain 10y agoI have a cheapo Chinese 2.4GHz video transmitter which quite effectively jams 2.4GHz wifi for hundreds of feet in every direction (as my neighbours let me know...) I've got a friend who claims you can force a DJI drone to autoland from well over 1km with some microwave oven guts duct taped to a satellite tv dish.

- adrianratnapala 10y agoI think microwave ovens usually use mangetrons rather than masers: https://en.wikipedia.org/wiki/Cavity_magnetron https://en.wikipedia.org/wiki/Cavity_magnetron It's true though that both of them are coherent microwave sources. And the magnetron is arguabbly more "laser-like" than a maser.
