Connectivity Issues - Service dropping, Packet Loss & Latency

[gk1227]

Same problem with SB8200.  "Config File Rejected due to Invalid or Unexpected TLV 11 encoding.  Modem periodically drops from DOCSYS 3.1 to 3.0 (blue lights change to green).  DS profile assignment change. DS Chan ID: 32; Previous Profile: ; New Profile: 1 2 3.   Also curious to hear of any resolution.  Problem has existed for about 2 weeks.

I having similar problems all of sudden. Speed test was showing me was getting all of the speed originally specified (300/30), now all of a sudden only getting 48/30.
