I think my cable modem is dying. It runs hot and lately my service has random disconnects that are typically resolved with a simple power cycle of the modem. It's a SB6121--a plain cable modem not a wifi router combo. My service provider claims there is no signal issue, but my modem is EOL and likely the cause.
My service tier is less than 100 Mbps and I don't see myself upgrading unless I receive a free speed upgrade (it has happened once). I'm considering three choices: 1) 644 Mbps (ARRIS SB6190), 2) 373 Mbps (ARRIS SB6183), and 3) 213 Mbps (ARRIS SB6141). All three will fit my service needs. But I'm wondering if a model that is capable of faster speeds might actually work more efficiently at a lower speed. Perhaps a newer model is more efficient and generates less heat, thereby prolonging the life of the unit. Is there any way to answer this without just buying them all and testing it myself? The reviews I've read don't focus on heat issues, just performance.
It has been in service for almost 4 years. I cannot say for sure if it's hotter today than when I first put it in service. But it does seem very hot around the CPU vents, leading me to wonder if it's overheating. Also a quick reboot doesn't fix it. A short 1-2 min cool down does, though. Thanks. I'll either try the mid-range one or the high end one. – jimp – 2018-08-29T21:25:49.713
