wifi

I’ve pretty much read all of the guides on here but I still can’t find one on what’s the best option when it comes to getting internet. Right now I’m using my home WiFi and I know that’s not preferred. How do most fraudsters get fast, untraceable internet? Is there a internet opsec guide

Hey I was wondering is there anyway to gain passwords through my home internet. My partner is cheating on me so I’d love to get into her Facebook or Instagram and read the messages as she denies it. The problem is the device she uses is a iPhone 11. I have complete control of the wifi though
