SB6120 Docsis 3.0 modem slows to crawl after few hours
Hi guys, I have an issue with this new SB6120 modem I got. Right after setting it up, I do a speedtest and it starts out at 50 mb/s, then gradually slows down to 25 mb/s by the time the download is complete.
But that's not my main issue. My main issue is that the speeds fall down to 6-7 mb/s after a few hour of the modem being on. I have to reset the entire modem to get back to the 50 --> 25 mb/s speed.
Is my modem faulty or is there something else going on? My older docsis 2.0 modem was stable at 27 mb/s with no resetting needed.
