Comcast Wireless Gateway constantly drops connection

Hi all,

I've been having issues with Comcast and a consistent signal from them over the past 3 years.

They issued me a modem back in 2009, I bought a new router to go with it every year until 2013 when I started having drops on the brand new router. I thought it was just that specific router I bought, so when 2014 started I got a new one.

No dice, I still had the same issues, and the drops would be as frequent from every 10-15 minutes or sometimes only 1-2 times a week. This was all remedied once Comcast issued me a new Wireless Gateway in November 2014 that is a modem/router combo. This worked great with zero drops until February this year when they started back up.

Up until now, the drops in connection would be painful, but only 3 times a day at most. For whatever reason these past 4 days, I literally cannot watch a 5 minute video on youtube without my connection dropping. It also sucks because whenever I game on my PS4 I keep on getting kicked out of multiplayer matches for a split second, and by the time it takes me back to the main menu of the game, my signal is back. I rejoin the game, 1 minute later I'm dropped again, and repeat. It has become so frustrating and from what I've read online it's an issue with Comcast since most people have had technicians come to their house multiple times and nothing is resolved properly.

As of now, this is the troubleshooting log:

As of now I don't know what most of that means, but I've become so frustrated as to how I can't stay in a match for more than a minute, especially because now is my vacation from work.

Any information as to what steps I should take would be helpful, and I can provide any other info as needed.

Thanks!

1- Do you have a splitter before the wireless gateway?
2- Does the connectivity effect both WIFI and LAN?
3- Does the problem happen over multiple devices?

CC's remote techs can see your equipment, read the logs, do several types of resets from a power cycle to factory reset. They can see the quality of your downstream & upstream signal to your equipment but frequently the problems CC customers suffer are related to overselling community bandwidth and simply letting the customers live with it. Most people imagine Comcast as this huge, uniform corporate machine in complete control of it's assets but what you should picture is a huge patchwork of small cable companies, with different infrastructure, software and abilities being bought and ruthlessly managed by CC. If you want the problem fixed, you need to go through a few low level, low effort field techs before they send someone with average intelligence to actually troubleshoot the problem and solve it. Document everything. Keep logs of downtime and have billing prorate the bill. CC phone support is good for general information but if you have a wire problem, they are a little blind to it because of poor training and high turnover of RSTs.
