My modem (SB6120) is intermittently losing connection (four times tonight, although usually it's at most once a day). Upstream and downstream power are fine, as is the S/N ratio. Coxtech1 told me that everything looks fine from their end as well. Powercycling the modem restores the connection; powercycling the router doesn't. Strangely, when this happens the pattern for the top four modem lights doesn't change (green, blue, blue, green, all steady).
Is there any reason to think it's anything besides the modem itself?
