How can I prove my ex is hacking my browser and stalking me?

To really secure your Wi-Fi, I recommend changing your router password and SSID. After you implement those changes, reboot your router to ensure only authorized devices can connect. If you are unsure whether your computer is compromised, it’s a smart move to wipe your system and install a fresh copy of your operating system. Also, consider using U2F or FIDO2 keys for two-factor authentication; they are a great way to bolster your security. Most importantly, try to cut off all communication with your ex to avoid fueling any interaction.

It sounds like you might be misinterpreting some things about your Wi-Fi. If there are devices connected to your network, their IP addresses will be in the same range, but they won't be connected to another location like his workplace. It’s a good idea to consult with a local tech expert who can assess your Wi-Fi and security setup. Without specifics or screenshots, it’s tough for anyone else to help you out here. You might also be misunderstanding the situation, so getting someone knowledgeable to look it over could really clarify things.

If you suspect that someone is able to hack into your Wi-Fi, you should definitely take measures to lock it down. Go through your router settings and block any unknown MAC addresses. Make sure your password is strong and not easily guessable. If you really want to confirm if your ex is accessing your stuff, monitoring your own devices is key. If you find any concerning evidence, don’t hesitate to reach out to the police; they can help investigate.

Creating some false information that you know is untrue could help you trick him into revealing how much he knows. If he brings up something you never shared, that’ll confirm he's getting info from somewhere. But, keep in mind, it's possible someone you trust might be relaying details too. The police will need solid proof, and vague evidence won't cut it—so try to gather concrete examples.
