Anyone else having coverage issues in Rosemont, IL?

frp0511

    My office is at the intersection of Devon and Higgins in Rosemont, IL, right where the westbound entrance to I-90 starts off of Devon.  The coverage map indicates 4G LTE, Excellent signal.  However, in my 4th Floor office, I get at most 2 bars, and super, wicked slow data.  Is anyone else having this problem?
