Having similar problems in OX28 for the last few days.
No problems reported in the area. When I am back on line, remote tests show everything fine.
Sometime just rebooting by cycling power on the modem/router restores service, but not always.
It doesn't look like a problem with my equipment or the modem, although I guess I should check the power levels.
If there is some local work going on which results in short interruptions, that would explain things. But, as I say, nothing reported on status page (although obviously I can only access that when things are working).
Just had another break. I tried removing the 10dB attenuator and retried. This time I have a connection, but it may have been a coincidence. With the attenuator removed, I have power levels downstream of around 9dBmV and upstream of about 44dBmV. I seem to remember that the optimum levels are both 0dBmV, but is that correct? It is a super hub 2.0. Can anyone point me to the documentation before I go searching?
I couldn't find the documentation on the ideal power levels. But I tried putting the 10dB attenuator back in and the connection is still OK, so maybe the attenuator is a red herring. With the -10dB back in, I see upstream power of about 51dbmV which looks correct: it has to increase the power to get through the attenuator. Downstream is now around 0 or -1dBmV which is what I have an old note saying is about right. I hope someone can confirm. Perhaps more importantly in both cases I see an RxMER around 40dB which looks good to me. But maybe I need to get a VM technician in, although I still suspect that is nothing to do with my installation.
Downstream: no lower than -6dBmV and no higher than 10dBmV - Close to 0 is optimal.
Upstream: no lower than 31dBmV and no higher than 50dBmV --- 44dBmV to 46dBmV is optimal.

Thanks for the information. Looks as if I can't get perfect levels with the supplied 10dB attenuator, but it looks as if I could be just marginal with it present. Maybe I should look to see if I have 5dB somewhere. Or get VM to fix it properly. And the temperature is fairly moderate just now.
