Upstream

Question

Do these levels look ok?&nbsp;&nbsp;&nbsp; For a while my upstream was running between 41 and 45.&nbsp;&nbsp; Overnight they shot up to 48 to 51.&nbsp;&nbsp; .&nbsp;&nbsp; Could home wiring go bad that fast, or maybe a plant issue somewhere down the line.&nbsp; Could a plant amplifier be going out?&nbsp; I'm not loosing connection so far.

What are you questioning...the Power Levels?&nbsp; Cox would have to provide your optimal specs but these look good.

We just had some bad weather and the modem disconnected overnight.&nbsp;&nbsp; Is that a sign of a plant issue?&nbsp;&nbsp; Unicast errors etc etc.

bruce · Answer

Disconnected overnight?&nbsp; How did you know it disconnected?&nbsp; You may have had a temporary power outage...somewhere on the route...but as soon as power restored, your modem renegotiated and returned online.&nbsp; The outage could have been at the plant but it could have been anywhere.
Do you have a bad connection now?

Signals have come down a bit (not going over 52).&nbsp; I guess there was maintenance in the area.&nbsp; Thanks for replying to me posts. &nbsp; I was just concerned over power levels because last year a plant tech had to repair a hardline to an amp that was&nbsp; barely connected.&nbsp; It was either due to past&nbsp; hurricane damage or whoever did it didn't care.&nbsp; Upstream has been around 41 to 45 until recently. &nbsp; I was concerned that this issue was returning because the amp isn't fastened to a pole &nbsp; It's just hanging after the power company changed poles.&nbsp;

Its all over the place.&nbsp; From 40 up to 51 and back down again.&nbsp; Not the normal 3 db variation that you would expect.
