Did some more testing with this and thought I would provide some data for others to compare with. Not particularly happy with the results. I conducted my tests from the office (oops) and now I can understand while some are unhappy with the downloading/streaming performance. Appeared to have a 'good' signal at the office, 4/5 bars (circles) on LTE. For the office, think large tower, plenty of windows, overlooking the city, so not underground but in a densely populated area. This is compared to 2/5 bars where I usually download at a friends and haven't really had problems there (less populated).
I chose to download the most recent episode of 'Elementary', an hour long HD show, at medium quality with the resulting size 634MB. It took just over 90 minutes to complete with about 10-12 disconnects. I tried to keep up but honestly just lost count there.
After some of the disconnects I ran a speedtest to quickly verify bandwidth and connectivity before resuming the download. The transfer rate ultimately comes out to be less than 1Mbps based on the math but it includes the disconnects and switching apps to perform a speed test and switching back.
And checking on my internet provider, admittedly much later during peak evening hours ET, shows connection speeds to several other speed test provider hosts. All of which meet or exceed expectations for a 20Mbps upload rate.
