I'm experiencing a high number of times where my Motorola Surfboard SBG6580 keeps "resetting" the connection and my provider Charter Communications refuses to do anything about pinpointing why it keeps losing the connection because "it's not our modem you're using" and "there's no issues in your area". My modem is kinda old - about 4+ years old I think and this happened about a year ago (modem kept resetting, losing connection, etc), so I did a search and found a forum that talked about how ISP lines are "dirty", old and sometimes bad causing the modem to have to "scream" at a high frequency to communicate with servers and keep doing the "endless cycling" to reconnect to a server. The forum recommended trying a ARRIS BDA-K1-RA Drop Amp with Active return to help keep the connection active.
This helped until a month ago - everything was stable, then the dropping and cycling has occurred every few days, then it will be stable for a couple days, then it will re-cycle again.
Now, I'm not sure if this is a sign that my modem is "dying" of old age and needs replacing or if Charter Communications is to blame for my issues and they just refuse to do anything since I'm not using their modem for $7.00 a month.
