I'm in the Orlando metro area and same thing, crazy slow "4G"... my speedtests are maybe 10MB down and 1.5MB up when I have friends on AT&T in Palm Beach/Miami getting 49MB down and 15MB up!
Most of my issues seem to be with apps though, like email taking forever to update (I use Exchange), Facebook taking about 1-2 minutes to update, Speedtest giving me 189ms ping results on average with the server being 20 miles away (Cocoa Beach, FL)...
I just called Verizon and they are going to open a ticket with their network team and have them look into it...
We will see...
Well, I think it has to do with performance inside buildings. I went outside again for lunch and ran a test and I was getting 15 down and 11 up no problem. As soon as I walked back into my office, it dropped back to 3G service and speeds. It now says LTE again but I think that may be a lie. I am surprised how pathetic the building penetration is for this LTE.
