Why is location services showing me in the wrong city?

I posted this in hardware but this is probably the better spot for it.
While using location based apps at home, sometimes it'll list me as being in Apopka when my actual city is Tampa. It's quite annoying when you're trying to use community based apps and you're not even in the right city. It'll sometimes adjust back to normal if I open up Maps or Waze but once my phone is idle for a bit, it'll go back to the same shenanigans. Is it a home WiFi issue or something wrong with the location services on my phone? I've tried turning off the location services, turning off WiFi, and turning off my phone in hopes of resetting whatever is the issue but it still occurs. Quite frustrating to say the least. Resetting my network setting and location services didn't seem to fix it either.

If it's a router issue, I have no idea how to fix it. We do have some Sprint Airave thing that boosts our signal inside the house. I'm wondering if that's messing with the GPS.
