Re: Not reaching full speed

Changed apartments, now speed has been terribly slowed. I have the 250mb package, but only 50 is coming through.

Re: Not reaching full speed

Will give this a try https://photos.app.goo.gl/BadYMCeQrLRPfYSU6 and then, I have channels with an average of 80, 000 uncorrectables; 20, 00 correctables; so as low as 500 uncorrectable.

Re: Not reaching full speed

You have a lot of uncorrectibles.  Likely an impairment in signal.  A good tech visit is needed.  Keep calling back until resolved, even if it takes several tech visits.  Could be bad line feeding lock box, kinked lines in lock box, noise interferring with signal, bad cable or connectors, etc.

Re: Not reaching full speed

The upstream power is fine. The downstream power is on the high side. The front end receiver of the modem may be being overdriven / overloaded a bit. That may be the cause of the uncorrectable errors which by the way may not be all that numerous depending on the total uptime of the modem since the last reboot. You could try knocking the downstream power down with the use of a 3 or a 6 dB attenuator pad such as this one;

Re: Not reaching full speed

Not sure why you posted the same high downstream power stuff and stats before ? Did you try using an attenuator ?

Re: Not reaching full speed

Was using something else that was not, attenuator came in. Using a 6db, but have three just in case.
