Superhub : Loss of Connection.

[MacmillaN]

Over the past two days i have lost connection to the internet in the evenings.
It happens at random times through the evening...

Hopefully this Helps!

Seems all right. Do you have a TBB graph?

[MacmillaN]

No Sorry i do not have a TBB graph, Do i need one?

[Kushan]

No but it's free and is a great way to monitor your connection. Gives you a good idea of exactly when the problem is occouring.

I am on the fence. Next time it happens I would have a look at your upstream power and error logs and see what says. I would bet that the high upstream has something to do with those T3 and T4 timeouts.

When I had upstream powers that high on QAM16 my connection was basically useless. Nowadays it's around 48dbmv and good. I'd get VM out to look at it.
