New arris modem 6141

[occalifornia]

The odd thing I have learned is that for some reason the retail "white" 6141 often fail to lock whereas the company issued "black" modems lock every time, even with same certs.

What could be the reason for this?

I've seen no issues in the same environment with either Retail / OEM White / Black or between Rev's. (Granted, I work in a test environment rather than in a home or production environment.)
