Modem: ARRIS SB6183 (Software Version SB6183-18.104.22.168-GA-04-37-NOSH)
Router: ARRIS SBR-AC1750 (Firmware 1.0.10)
For the past 5 months, I've been experiencing fairly persistent intermittent connection speed problems, requiring routine power cycling of my modem, a few times each day.
Last Saturday, a Cox tech came to my house and said that my connection is fine. The wiring at my house is fine.
I just got off the phone with a rep at Arris.
He said that the SB6183 is the only modem currently sold by Arris which requires a power upstream bond channel between 51 dBmV - 45 dBmV. Without this, users will suffer performance problems. He also proclaimed that this problem is often overlooked by technical support representatives, due to it being an anomaly.
The Arris rep said that Cox needs to increase the signal strength being sent to my modem, within these numbers: 51 dBmV - 45 dBmV.
It is best to be in the middle of this upstream bonded channel power interval: 51 dBmV - 45 dBmv.
Please adjust my upstream bonded channel according to the requirements for my modem.
Continuing to experience performance issues, in regards to speed.
Just got off the phone with Cox tier 2 tech support rep, stating my modem signal is within range.
The Upstream Bonded Channel cannot be adjusted to ensure it is within ideal power range for this modem.
On the phone with Arris now. Tempted to return this SB6183 asap.
Both modems need a an upstream bonded channel power signal 51 dBmV - 45 dBmV.
Without this signal, they will experience performance issues.
Suggested solutions for Cox:
Use attenuator: to adjust
Add new / change current splitter configuration
Adjust amplifier / service amplifier at house / service port at street
A rep was here for 10 minutes, installed an attenuator.
My levels are better now.
