Gordon, May 29

The cradlepoint CBR400 router and the Verizon modems have been working, but have some issues.

On May 27 and 28, the router would go offline periodically, and not be pingable from the local network at address 192.168.0.5 (cbr400). From the web interface (http://cbr400), System Settings -> System Control -> Advanced, I turned off "Enable Watchdog Reboot" to see if that would help. The CBR400 stayed up all night. When we arrived at the trailer (9:20) it was pingable, but the web interface would not respond. Tom reported that the internet was not available. However the router_check.sh script on the high dsm, which runs every 15 minutes, did not report a problem in pinging eol or google.

The 3G modem has been working fine. On the web interface for the CBR400, the signal strength is typically -75 dBm, with 4 bars.

The 4G modem does not connect. The status page shows a signal level of -79 to -84 dBm, which I presume is acceptable.

The CBR400 sends log messages to the syslog on "flux". The 4G modem is known as "WAN:9d7c85c4". The logs show "carrier reject", and that it reverts back to 1XRTT (2G):

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

Until we can get the 4G modem to do better than 1xRTT, we'll use the 3G and disable the 4G.

Here is the display of Status -> Internet Connections -> "Modem: Novatel Wireless CDMA" with an EVDO connection:
