Got a free 'upgraded' modem, and my internet has been cutting out about 10 times per day ever since.

As a non, Cox employee, gamer, reading this, let me preface this by saying, the modems cable companies sell ya'll are ...GARBAGE. I've been with Cox a long time. They come do stuff when they say they will they have people on a chat room at 3:00am when I'm gaming on the weekend. They won't come out and tell you this... But you need to ditch whatever modem they are selling you and get a Motorola or some third party that you look it up on their website or call and ask if it's compatible.  I have the Motorola Arris SB6183. Bought it like 5 years ago. Not expensive. It screams. Also, don't run 30000 feet of Wal-Mart cheap cable to your 2002 VCR, DVR's and whatever in your home. Use CAT 5 or 6 cables to connect to gaming systems. Wi-Fi users are mostly "Noobs" (Speaking the language) And ask Cox how much it'd cost to run that high dollar cable inside the home that they have on the outside. Luckily I had a buddy work for them, gave me some. He don't work for them anymore, so I'm not getting anyone in trouble by saying that.

I had THE WORST luck when I had this house initially, and it was due to a roommate with 5 or 6 splitters and Wal-mart junk cable running across the carpeted floor, etc. There's probably a 10 page log on my account at Cox and they probably had me flagged back in 2004-2006 as a "problem customer" or "Needy".  Ask them how many times I've called in the past 10 years, since my buddy gave me that cable and I bought a 3rd party modem. Maybe twice in 10 years. ALSO, you need to set your router up for static IP on your console and manually put the DNS servers by running tests. GOOGLE and YouTube how to do it all. IT's out there.
