High latency or timeout to first hop in Spectrum network
I'm having high latency issues on my first hop to Spectrum network. See my Ping Tracer graph below:
The first row is my home router. The timeframe was this morning from around 8 am to around 10 am. I think this is a fairly typical representation of my connectivity.
My cable modem is a Motorola SURFBoard SB6180, which is not on the Spectrum approved modem list: https://www.spectrum.net/support/internet/compliant-modems-spectrum-network/ This device was provided to me when I initially signed up for Internet service through Time Warner.
How likely is the issue my cable modem?
Would Spectrum replace the device?
Thank you for any help you can provide.
