Well, I got my R850 MiFi hooked up. Only get between 1 and 2 bars of signal (out of 4 or 5).
It's barely enough bandwidth at times to stream internet radio, which is what, 80Kbit/sec?
I moved the MiFi into the other room, and my fast.com speedtest went up from 200Kbit/sec to 1.7Mbit/sec, but judging by the fact that the radio is skipping badly, it's having trouble. I have my main router connect to it via WiFi client mode.
Edit: I'm downloading three Linux ISOs at once, and I'm getting something like 5-6KB/sec for two of them, and 85-200KB/sec for the third.
I checked Sprint's coverage map for this device and my address, and they show two items, "Best" (which they say is what you get from an indoors experience), and "Fair" (which is supposedly what you get if you're "on the road" there).
So, if their coverage map shows "Best", why am I only getting 1-2 bars of signal, and such poor xfer rates? When I signed up for the service, they claimed 12-40Mbit/sec speeds. Which I thought was perfectly fine landline-esque speeds.
