DPC2100r2 Problems

[freebullets]

I'm using a subscribed DPC2100r2 with Haxorware. For the past few months, internet has been dropping occasionally, and the modem needed a reset. For the past couple days, it's been dropping every 10 minutes, and I'm getting high pings. Log:

I don't remember seeing the TLV-11 message until now. From this thread, I take it that's my issue? What does the error mean, and how can I fix it? Is the stock firmware for my modem available for download somewhere? I forgot to back mine up when I installed Haxorware a couple years ago.
