Logging into Router via browser shows a different network than mine.

Hi, thanks in advance for looking at this!

When I try and connect to my own network via the browser, typing in 10.0.0.1, it takes me to my neighbor's apartment. I've contacted technicians about this, they have no idea what's going on. They've checked the wiring on the outside of our building, and they say everything looks good. I'm unable to make any major modifications to my internet because of this, and I am limited to making changes via the XFi app. 

I am wondering if anyone has ever seen this problem before, or if anyone has fixed this.

Thanks!
