If it's one of their new Netgear-branded modems, see if you can get your
tech to dig up an SMC.

We had the same issue.  They swapped out one Netgear modem for another
Netgear and the problem continued. The phone techs couldn't see the problem
and kept blaming our equipment.  They finally sent out one of the 'senior'
engineers I had worked with before on other jobs.  He managed to get a hold
of one of the SMCs from their warehouse.  No more issues.
