Packet Loss and Latency Spikes

This is not the first time this is happened (it happens periodically), but I am having issues with packet loss and disconnects between my modem and the ISP (hop 2). They are intermittent and very annoying. I pay $75 a month for fast internet, and I am the only person who uses it, yet I have constant problems. I had these issues with the old Cox-issed Cisco modem and my current Surfboard SB6183. Same issues with three different routers as well (Apple AirPort Extreme, Netgear Nighthawk X6, Linksys WRT1900AC). It has to be on Cox's end, but I get zero help when I call in and talk to support. They always ask me stupid questions (have you reset the modem, have you checked your router, have you tried connecting directly to the modem via ethernet, etc.) and say everything looks fine on their end. I had a tech out last month and he pulled a filter/splitter off and replaced it and said things were fixed. I was at work when he came and my housemate said that he was here for about 10 minutes. Below is a screenshot of Pingplotter, the status page of my modem, and the event log of my modem.

    I can't make it through a single game of Overwatch without getting disconnected. This is absolutely infuriating. The last time I had this issue was on Thanksgiving weekend. I am off work this week and was looking forward to relaxing and being able to play games online, and here's what I get. $75 a month to not be able to use the internet. Last time I had this issue I was literally able to play more reliably using my phone as a hotspot than I was using my home internet. Something is wrong here.

    I'm not seeing the modem online when I check from this end. Are there any cable splitters you can try bypassing and seeing if that helps?

    I unplugged the modem overnight. There are no splitters, I went and looked in the box last night. Just a ground and cables (reused DirecTV coax cable).

    @thehollowwaytape

    I do see the modem back online now with good signal levels but it is reporting lots of power adjustments trying to maintain sync. Do you have the modem plugged into a power strip with a lot of other devices? It may be helpful try connecting to a different power source and see if that makes a difference.

  • thehollowaytape's avatar

    It is plugged into a three-way splitter. I'll try plugging it into its own outlet and report back.

    I didn't have many major issues yesterday, but the issues are back today. I have the modem plugged into it's own outlet with nothing else, and my router is plugged into its own outlet as well. The PC I am running PingPlotter on is connected to the router with a brand new CAT 6 cable. I have connected directly to the modem and these issues still occur, it is nothing to do with the router. Here is another PingPlotter screenshot from a few moments ago.

    @thehollowaytape

    You could also try seeing if the modem works better on a different cable outlet. Otherwise it may be time to see about having a technician come out and troubleshoot further.

    @ChrisL

    I do not have another outlet hooked up here. Almost every time I get these drops I'm getting a Dynamic Range Violation, which from what I can gather is the modem having to exceed power specs to maintain upstream sync.
