Replaced 4G modem with another 3G. So two-3G modems are running at top of tower. 4G would not stay connected with 3G signal. [crying]
Gordon, June 13
On June 11th we took the 4G back to Tuscaloosa and tested it with VZ Access manager on Chris' macbook. I worked well, making an LTE (4G) connection and staying up. As I remember download/upload speeds (measured at dslreports.com) were around 2.5 Mbit/sec.
On Jun 12 we took the 4G back to the tower. It would only connect for a couple of minutes at 3G speeds (EVDO-a1) and then drop out. This was with and without the 3G modem connected. Also, I never have seen the 4G modem make a LTE connection. So it appears only 3G service is available in this area. With the external antenna at the top of the tower we have good signal, with an RSSI of about -63 dBm.
I tried settings on the cradlepoint to limit the 4G to 3G speeds only, and to 3G or lower, but it still did not stay connected.
Replaced the 4G modem with a 3G and things are working well. Both 3Gs are connected at 3G speeds (EVDO), and have stayed connected for 23 hours. load-balancing=spillover is enabled.
Attached are the info pages shown from Status -> Internet Connections, after pointing a browser at 192.168.0.5. The 3G that has been on the tower since the beginning has phone number 303 241 0359, unique identifier d163a26c. The new 3G modem is phone number 303 241 0137, unique id 76f22d5e.
