[Wlug] Test needed on declared-ill Modem. Who has a lab? -- + update from ISP

Thanks, Karl.

This makes sense. Why didn't I think of that! We have inadequate elex here
which dips & dims lights frequently. Had sudden power outages a few times,
including one very recently. I am not piping the modem logs anywhere; only
check this if I notice an obvious problem.

Results:  Non available. Case (Motorola SB 6120) has only 2 screws, hex, 2
different sizes. No problem. Backplate then comes off & that's it. Nothing
else to undo except whet seem to be clips, but we have no prybar tiny &
thin enough to pry up these clip things. Case appears uncrackable, execpt
maybe by dropping it from an airplane onto solid concrete.

However. If it's only the power supply, I could test this by simply
replacing the wall wart with an equivalent one from anywhere. Then I'd have
to get the ISP to reprovision it, then watch to see if it worked any better
after that.

I do have an update from Ch4rter business office, which is relevant to my
original beef with this ISP.  Yesterday afternoon, I followed up by calling
the business office, to ask why they changed their policy on what
networking components their customers can or cannot own and administer
themselves.  The last person I spoke with said I am "grandfathered-in" to
be allowed to own & run my own modem, since my account was opened before
July, 2012 when the new poilcy was instituted (I'm a customer since there
was something other than dial-up). Biz office says these techs who came to
see me Thursday simply had "inadequate training" or "incorrect information"
from their own supervisors.  Both techs did look not older than about 3
days over 19. For the trouble call, I was promised a sup-tech & maybe one
of these was, but only sup-ing the second guy how to open cardboard boxes
of modems, smile at geekly grannies, & maybe how to drive the van.

This modem is not in warranty & no longer manufactured (mine 2+ years old).
But Motorola tech support confirmed that any old power supply 12V,  0.76A
would run it. I'll borrow a power supply from somewhere, then try this
thing one more time here before Responsibly Disposing of it by donating to
a worthy friend's parts bin.

Thanks very much,
Liz J
