Jamming isn’t so trivial because it’s not really the volume but the signal to noise ratio that really matters no matter how much energy the aliens use. Therefore, I propose that this question doesn’t make technical sense.
Tell that to my microwave and WiFi router.

Wi-Fi is interesting. It’s designed for maximum bandwidth at low power levels. It also has a carrier sense system to prevent interference with other unknown devices on the unlicensed spectrum. Most things are sacrificed for that bandwidth, such as exploiting multipath and spatial propagation differences to squeeze out every last drop of data. Orthogonal carriers are spaced very close together maximize the available spectrum.
Still in this case, Wi-Fi operates at other frequencies that do not get microwave interference, and wireless network might explicitly be trying not to interfere with the microwave because it could be a device trying to share the unlicensed spectrum. The other Wi-Fi frequencies don’t go very far and aren’t good at penetrating walls, so the amount of power that an alien spaceship would have to use to block these signals categorically is crazy high.
