Wifi is actually very easy to use.

Wifi element can accept spark from any metal (Except NSCN), but can only give spark back to NSCN, PSCN and INWR. As you can see in this image, the spark is going into WIFI at the end..

...And then back out the other WIFI particle, which is surrounded by an excessive amount of NSCN just for example.

Different particles of WIFI have a preset frequency, and can send sparks over ANY distance without any lag at all. There are 99 frequencies, all of which are 100 degrees apart, a link to all others in the same frequency will be shown when mouse over one of them. They behave like insulation with heat, and must manually be heated in order to change the frequency of the element, which visibly changes color to reflect this. For example here, the WIFI on the outside is -270 temp, while the inside is 700 temp. Particles of WIFI do not exchange heat with any other particles.

It should be noted that wifi channels start with -273.15 to -200.01 being the first channel, but from there they go by hundreds (-200 to -100.01 being the next)

As a result of this mechanic, any WIFI particles that get sparked will all release a spark if they're nearly the same temperature. If you have 20 WIFI particles and only one of them gets a spark, if all the WIFI particles are nearly the same temperature, then they will all release a spark at the same moment. In this example, I only added one particle of WIFI, but it received a spark too. You can't easily see, but there's one particle of NSCN touching it that allows it to give off spark.

Lastly, WIFI particles of different frequencies will not give spark to one another. You may use this to make sure that a spark to one wifi will not spark all of them by accident, and with 99 channels you can massively change the way electronics are designed. In this example, I have the wire set up to infinite loop.
