I think in general creepypastas are not made to have continuations like this. Creepypastas are horror short stories, and like normal short stories are using twist endings and open endings for good effect. Once you make some sort of Part 2, it destroys the ending of the original, by either taking away the mystery of the open end or trying to put another twist ending on a twist ending while reverting the original twist or both.
There's a good reason, why we don't have something like "The Lady, or the Tiger? 2: The Choice Made". For the same reason there never should have been a "Abandoned by Disney, Part Xyz" or "Candle Cove - The untold Story" or "My personal encounter with the Slenderman 8: A blossoming Romance". If you really want to make a creepypasta, make something new, doesn't even have to be an original concept. You can use all the old tropes, as long as you tell the story competently. Psychosis was just a take on the old "Invasion of the Bodysnatchers" Plot and it turned out to be one of the best pastas out there. Just don't make a straight up sequel or -god-beware - a fan-sequel.
About the Wi-Fi:
I'd actually consider this to be another part that's just straight up silly and should have been left out (Didn't even notice it that much at first, but the more I think about it, the more farcical it becomes). I mean, what's the implictaion here. Are the demons using Wi-Fi? Is Zombie Mowgli browsing the web on his smartphone? Does Satanic Snow White have an Instagramm? Is Devil-Worshipper Nick on Ebay right now, searching for a new Sacrifical Dagger?
Wi-Fi is something that just doesn't add well to the kind of story this is trying to be. Wi-Fi is something that implies a non-supernatural cause, like a normal person setting it up for whatever reason, which isn't scary (When Hipsters go Camping: A real life Horror Story) - and the alternative, some supernatural entity installing a Wi-Fi hotspot in its home, is just comical (Vodafone Contract 666: Flatrate to Hell).
It could work fine if the plot was about cyberdemons from the internet. It doesn't work for Undead Mickey and Friends.
