Hello,
I've had the Motorola SB6120 for quite sometime and while I've had some connection issues in the past, it was generally due to much signal noise, followed by a reboot. I then had the lines reworked a bit and have been smooth since. Just the last couple days I have been getting no connectivity, however, the modem is sending and operating as normal without rebooting. I cleared DNS cache but that did not work. It will stay online for a while, but never more than 2-3 hours.
My modem log doesn't really look any different than when it is operating normally - though does show some high upstream @ 51dBmV.
The main confusion is that my "LINK" light is blinking as normal...
Firmware issue potentially???
Thanks for your time!
