> Yeah, I think it's more what lgats suggested, and simply that they have a naturally impermeable building in the middle. That kind of contradicts the OP... since they said that it was only recently that the signal stopped working, and that the building was not being remodeled during that time. So if the building is now impenetrable then something changed. Maybe modern phones just have a horrible time falling back from LTE to 4G/3G.. But if that’s the case then I feel like the OP would have checked for that since he seems to have already been tracking his connection strength over different locations and over time.
