First of all, a modern microwave shouldn't leak much, it should leak barely anything!
Just that you know, nearly every wireless transmitted signal is in 2.4 GHz. That often includes, baby phones, microwaves, wireless flash systems, wireless cameras (which aren't Wi-Fi standard based), Bluetooth, ....
Regarding some mentioned points, 802.11n works in 2.4 AND also in 5 GHz, depending on the accesspoint. Only 802.11ac works solely in 5 GHz, but most devices aren't yet 802.11ac ready.
If you buy a new accesspoint (802.11n or today better 802.11ac), make sure it's a dual-band device, that works in both frequencies. That way you keep compatibility to all your devices (game consoles and older mobile phones/tables often only work in 2.4 GHz).
