150M Speed Issues / Power Levels

Pushkar · 05-10-2016, 18:37

Hi all,

Long time no post here... regrettably getting horrible speeds and only about 5mb on a 150mb package now.

Could somebody check these power levels?

Many thanks.

Upstream is too high, errors and poor snr on 227mhz. Check the connector into the modem, if it's loose tighten it up and the levels may well fall back into spec

And 219 sorry

Thanks - connector is fine and have reset numerous times now.

Reckon an engineer can sort it, or looking more like an area fault?

I think it's a loose connection somewhere, 219mhz and 227 always seem to be affected by a loose connector. And I've had a few recently with upstream being affected as well, which I hadn't seen until recently. I could be wrong, it's hard to detirmine without being there. Back when I was a service tech if I had a customer complaining ceebeebies was breaking up, it was carried on 219mhz then, and was almost always a loose connector.

Thanks - I will try and remove all connections and replug in again in the meantime.

As well as the SNR issue above you only have a marginal single upstream channel on QAM32. Power level is too high for a reliable connection and is probably resulting in high packet loss and consequent poor speeds.

If there are no wiring issues as suggested above and no return path attenuators on the back of the hub you'll need a tech visit.
