I plan to contact Verizon and see if they can help from their end concerning the 4G modem.
Morning of May 29:
Upgraded firmware on CBR400 to version 4.3.0
Speed tests: http://www.dslreports.com/speedtest?flash=1
state | download | upload | latency |
|---|---|---|---|
3G connected, 4G disabled | 413,444 | 380,309 | 121,107 |
4G connected, 3G disabled | 58 | 127 | 485 |
So the 3G is working better than the 4G currently.
