Please also send me details on how to try this firmware.
My symptoms are similar but different in some ways.
I've wasted the better part of two years blaming Comcast and looking at the routers on either side of the LB2120.
After an outage yesterday I did an experiment that Comcast recommended -- just unplugging the ethernet between the LB2120 and the cable modem, waiting 10 seconds, and plugging the cable back in -- no power cycling -- and I was floored when the LB2120 immediately connected to the cable broadband and stayed there.
Their theory was that the LB2120 was being "impatient" when testing the broadband to see if it was up, and that it would then switch to cell, and back to broadband, and back and forth. Often I'd get 300+ SMS in an eight hour period before I could get over here to physically reboot everything.
Anyhow it sounds like this firmware might help or eliminate my problem.
