Send it back on the post to hunt the baby tech bros.

Or to destroy a data center.

Just like the T-800 and K2-SO. Reprogram all the droids.

With a just a few just large enough neodymium magnets.

No signal, no movement, no data.

I mean, that won't really work. It dampens the signal, not eliminates it, and in order to block communications, you need a net width small enough to block 1/4 wavelength which is 5cm/4, so <1 cm holes with a material thick enough for the damping.

That would be a net that weighs like 20kg lol and it would essentially be a solid cage at that point

Not to mention that it would have to fully encompass them.

Better to just use a signal jammer like they do for drones.
