I was plagued with the same puma 6 with the Arris SB6190 I now have the SB8200 planning for the future. My area has its monthly cycle of great quality and a week of **. reason I replaced the SB6190. Some things I have learned. This thing called MoCa if your neighbors use a MoCa network like the panoramic wifi Cox offers and you or them do not have a POE MoCa filter you may be getting some interference from their network. MoCa filters are cheap or Cox may provide one. this helped my modem since the SB8200 has no MoCa blocking capabilities due to the DOCSIS 3.1. But look in to a MoCa filter, did help my situation but still my area is bad in connection as usual
I pay for 300x30 current speed 12x30 alway great here in my area.
I collect a lot of uncorrectable when the quality in my area gets bad not sure what causes these to include a few days of errors. ranges from level 3 to level 6 errors. I belive a lot of our connection issues have become more frequent every time a new speed level is added and cox is unable to sustain in the beginning. im looking fwd to cox fiber I have my fingers crossed that it makes it to my area.
good luck
