Unlock Shampoodles without Wifi access

Title sums it up a bit. I've got an animal crossing save that is only two years old, and nwfc got shut down way before that. I can't change the wifi to a wep key, and turning the security off just seems too risky, especially since I live with other people.

I've tried hotspot apps, basically attempting to filter the wifi into a hotspot so it would connect to the wifi. I did have a phone with a hotspot and I remember it would pop up but wouldn't be accessible. Anyway, please help guys! If I can figure out the wifi stuff would be so much easier
