First time posting, long time lurker.
Have had excellent LTE coverage, first on my Nexus 5, now using a Nexus 6, for over a year now. I work at Colorado and Exposition.
For about a week now, I've had issues with the phone connection dropping on LTE, although the icon still will show full or nearly full bars and the LTE symbol. I have to put into airplane mode and back, it'll establish connection, and everything is fine for as long as I'm using the phone. Then I put it in my pocket, pull it out to use again a few minutes later, and the process repeats. If I set the network mode to 3G, it functions normally (i.e. don't have to reset the connection using airplane mode).
I received OTA Marshmallow about 4 weeks ago (first or second day after release) and had no problems previously until 8 days ago. This only occurs at my work location. LTE connection is fine at home (20th and Youngfield) and fine at Children's Hospital (Aurora), Castle Rock Outlet Stores, and downtown (Buell Theatre area) during this last week.
Thanks in advance for any advice on what my problem could be...
