Constant T3 timeouts for the last 3-4 weeks.

Hey everyone,

For the last 3-4 weeks, I have been experiencing drops in my internet connection. I'll be in online meetings or just randomly browsing the internet and the internet will cut out. Most of the times it will only last for a minute or two and then be working again.The lights on the mode don't show any disconnection when it happens, except for yesterday when it rebooted by itself strangely, but all the other times, the lights are fine.

Since I'm working from home these days, these disconnections during live meetings is really affecting my work. It seems like they are happening more frequently. So i went and checked my Arris sb6141 modem logs, and they are made up of mostly T3 timeouts.

I called cox and the lady didn't seem to know what I was talking about when I asked about signals coming to my house maybe being bad. She assumed I was talking about wifi signals. She went through all the usual steps that I had already taken before checking logs such as: reseating coax, hard reset, connecting straight to modem by bypassing wifi router, etc.She said I was connected but I tried letting her know, that these disconnections happen all throughout the day and connection is lost for 1-2 minutes at a time.

And then she proceeded to say I needed to buy a new modem. Needless to say, none of this helped and again, the internet went out not even an hour after getting off the phone. 

I am really frustrated, and don't know who to contact to get this problem addressed as normal tech support hasn't helped. Any help or advice would greatly be appreciated.
