new modem needed?
I have an arris SB6183 and the 400Mbps plan. I used the modem with little to no problems for the last two years (bought it new), then recently started having problems after I moved. I get random packet delay/drops (once every 5ish min) and occasional modem resets (1-3 times daily that I've noticed). My speeds are also much slower than I'd expect, never surpassing 100Mbps. I wanted to get someone out here to check the downstream power levels as they sit around 9ish dBmV (close to the spec limit) and I have read that high power levels can cause some issues that I have experienced, but the tech on the phone told me the issue was that my modem is old and I need a new one, does this sound right? This modem is still being sold in stores today, so it seems odd to me. My modem logs are also absolutely full of critical alerts, can post if they'd be helpful.
Note: I know that 400 is pushing the capabilities of the modem I have, I am more than fine with only getting 300ish due to the modem. Perhaps that could be causing the slow speeds, but I don't see how it would be causing the resets and packet loss.
