Hi @Skohon25,

Are you able to post some screenshots of a few traceroutes, WinMTRs, or PingPlotter results? Also are there any splitters or amplifiers that are connected to the coaxial that is screwed into the back of your modem? If so can you bypass the splitter/amplifier and plug it directly into the wall from the modem?

    Hey Ben,

    Thank you for reaching out.  I am going to attach several screen shots of my T3 Time-Outs, Channel Power, Packet Loss, etc. I added a splitter yesterday thinking it may boost the Upstream Power, but there was never a splitter in the line for the past year while we had no issues.

    I may go buy another modem today just to test and see if a new one would work.  I am currently using an Arris SB8200

    Thank you for your help!

    -Steve
