Upstream Power 50–52 dBmV, No Splitters, Downstream Perfect – Request Line Tech Visit
Hi,
I’m looking for help with a persistent upstream signal issue that hasn’t been resolved by remote troubleshooting.
Situation:
Modem connected directly from wall jack (no splitters)
Xfinity performed a remote reset/reprovision, but levels did not change
Downstream (looks good)
Power: ~+6 dBmV across channels
SNR: ~43 dB
Very low/no uncorrectables
Upstream (problem)
Transmit power consistently 50–52 dBmV on all bonded channels
From what I understand, this indicates the modem is compensating for return-path loss, not a configuration issue. Since downstream levels are clean and there are no splitters in the unit, this seems like a line / drop / tap balance issue, not an in-home wiring problem.
Because reprovisioning didn’t help, I’m requesting a tech visit to check upstream levels at the drop and tap and correct the return-path signal.
Please let me know what the next step is to get this scheduled.
Thank you.
