Thanks Jennifer! I really appreciate the offer. What info do you need from me? Here's a shot at the map.

I'm using a uml290 with 100' of LMR600 cable to a 16dbi Yagi antenna. When I'm not dealing with support, I have the modem in a Cradlepoint mbr95 router.

Here's my stats from when the network tanked about a month ago:

Here are some stats after an almost 2 week outage (the same period as above) during which I physically troubleshot 4 local towers sitting in my car with the modem in a netbook, on the phone with several techs. I later received a callback stating that they had discovered a network problem.

Note the router captures LTE SINR as "lte".
