SB6190 Event Log with Internet speed 73 Kbps from Cox Preferred 100 Mbps service

I have intermittent connection issue.

The COAX cable is connected directly to Arris Surfboard Cable Modem SB6190

There is no splitter.

Event Log

The table below contains the log of events that the SB6190 has detected. This log can be important to the service provider to help diagnose and correct problems, if any should occur.

    We are looking into the slow speeds when accessing Netflix we send updated once our network team has gotten back with us thanks for your patience.

    Hi All, I checked the Netflix speed test, fast.com, at 1:00 am PST. It showed 100 Mbps. This is to confirm, we have slow speed during peak hours. iwinner

    Hi TiffanyR,

    The problem came back around 1 pm today.

    The internet speed dropped to 200 Kbps for COX preferred 100 Mbps.

    It is the same direct connection from COX to modem without splitter.

    The service was great before 1 Tbytes cap.

    I am looking at competitors now.

    This happens in January 2018.

    I am not going to activate TV service yet as it requires splitting the COAX signal.

    Hi Tiffany,

    Thanks, I'll stop over at solution store this evening.

    Initially I only have Internet service and I am adding TV service.

    I notice, the coax cable is directly connected to modem.

    There is no signal at the wall-outlet for contour (HD receiver).

    Hi TiffanyR,

    It is strange that I powered down the router and the Arris Surfboard SB6190 over night.

    I'll contact the Arris support on this issue.

    This morning I checked the COX status is "Service Connected" and speed via Fast.com = 100 MBps.

    http://192.168.100.1/cgi-bin/status shows good on downstream bonded channels signal noise ratio (SNR) around 35.0 db

    I cleared the log last night and this morning shows the CM event log empty.

    I am planning to add TV service, should I buy a 2-way HDTV/Digital Cable splitter (5 MHz - 2.4 GHz) from Home Depot or ask for Signal Amplifier + splitter from local COX store.

    i.e. I need the signal to the Contour and modem.

    Any negative impact to the internet speed after splitting the signal to Contour and Cable modem?

    Thanks,

    iwinner
