Update on 4gCommunity
I was puzzled, this morning, when I realized that I was only getting about 2.5 Mbps. There were even periods of time when I was only getting 900 kbps. Ouch! When I went to bed I was getting a steady 9-10 Mbps.
I went to the hidden menu (192.168.128.1/hidden) on the Franklin R850 and saw that I was connected to Band 26. Yesterday it had mostly stayed connected to Band 25 (typical, for our house). I disabled Band 26 so see if I could force it to connect to Band 25-- but it wouldn't make a connection to the network. No Band 25. No Band 41.
It was dead, Jim.
So I re-enabled Band 26 and it connected.
I did a profile and PRL update to see if that would make a difference. It didn't.
At this point I was convinced that I'd gotten a defective Franklin R850 or that I was somehow being throttled or limited by 4gCommunity or Sprint or some dark force in the universe that had it in for me.
Just to be sure, I grabbed my FreedomPop Netgear Fuse, because it is LTE-only and has similar specs to the Franklin. I also knew that it pretty much ALWAYS gets around 13 Mbps and connects to Band 25.
To my surprise, it connected to Band 26 and only got about 2.9 Mbps.
No grand conspiracies. No dark forces. Just some apparent network issues or maintenance going on that have Band 25 unavailable. (I don't think we have Band 41 available, around here.)
The moral of the story: sometimes there's nothing wrong with your stuff. The problems may be upstream and will probably go away without any action on your part.
