High Split Caused Unstable Internet Connection
At the beginning of March, Spectrum had made the High Split upgrade in my local area. Ever since then, my internet connection has been extremely unstable, intermittently dropping for about a minute. Sometimes with the light on my router remaining blue, other times going red. I had my router replaced twice, my modem replaced once, and all of my cables completely replaced. None of it worked. And now my Spectrum Field Supervisor has basically been ghosting me after he sent the ping monitor data I sent him to the hub team. I have no other options other than to make a post asking for help or advice.
For context, my internet is in my grandmother's name, as I live with her. So everything would have to go through her. That means that it's extremely unlikely that she'll switch to any other providers. I will look into different providers when I move out, but for now I have to stick with Spectrum and find a solution. Our plan is the 400mbps download speed plan that we were seemingly grandfathered into, as it is $100/month when the 1gbps plan is only $20 more.
Any help or advice would be greatly appreciated, it's severely impacting my ability to play online games when it was perfectly stable before the High Split upgrade took place.
