Why does the same network id show up when I look up available Wi-Fi no matter where I'm at?

Lately, maybe the last 2-3 weeks I have noticed something that seems odd and I can't find anything online I'm hoping someone here can help! I have an iPhone 4s that I only use for apps not for my cell phone, the phone is not on any service provider. I'm able to connect to the internet as long as there's available Wi-Fi which everyone knows already! I started noticing that no matter where I was whether it was at my house or 30 miles from my house the same Wi-Fi network id has been showing up. It is a secured network I've never accessed it… I mainly use mcdonalds Wi-Fi or Starbucks etc. If not at home. My question to you is… Is this normal? What reasons could this be happening? I have someone in my life unfortunately that has been known to track me in a number of ways, could this have something to do with a way they could be tracking me or maybe my car or something? I really have no idea, maybe I'm overreacting and it's normal that's what I'm hoping someone out there can help me figure out! Thank for your time!

Clear your network settings

SETTINGS
GENERAL
RESET
RESET NETWORK SETTINGS

that will remove all saved and known networks

be sure you know passwords to any coded ones so you can access them next

as to whether its a spyware of some sort I don't know but doing the reset will give you a clue if it doesn't disappear. Have you googled its name?
