Seems completely random, interrupts my work from home just about every day.
I have some modem logs and connection info. (Taken during a time when it is working, not sure if any of these numbers change when things go wrong)
Drops are 3-10 minutes long.
We pay for 250mbps package.
We've had techs out probably 4 times, issues were found each time, but this issue is persistent.
T3/T4 errors are of the hardest problems to get Cox to even admit, never mind fix. First thing to do is rule out your side. How does the coax get from the street to the room the modem is in? Any splitters/amp/filters?
I wish I knew exactly.
What I do know is there's a node/tap on the other side of the street, then we have a box on our side just for us, then a cable through the yard that was replaced around a year ago, then box on side of the house, then somehow it gets into our attic and comes down into our bedroom on the second floor.
What are T3 and T4 errors?
Would replacing the modem help in this case?
Thank you for responding!
I suggest visually tracking the coax from the box to the bedroom on the second floor. What actually are T3/T4 errors is complex, but they are usually caused by noise on the line, usually from a bad connector or damage to coax that creates a leak. Instead of signal leaking out of the coax, bad signal leaks in. Generally cellular signal, but can be many things. In your case, your upstream OFDMA channel is low. Usually you want it as low as possible, because the modem increases it's upstream signal when Cox's side tells the modem it can't "hear" it. However if it's too low, any intermittent noise on the line can cause problems. Think of it like talking to someone at a party. You base how loud you speak on how much party noise in in the room. If it's really quiet, you may whisper, but then if someone starts yelling, the other person suddenly can't hear your whisper. So like goldilocks, you want the signal not too high but not too low. Around 42 is the sweet spot IMO.
TL;DR Make sure you have a direct connection from box to modem. If so, problem is likely outside and you should contact Cox to have a technician out to investigate. If they escalate it, make sure to get the ticket number for follow up. If they can't fix it or won't escalate it, file a FCC complaint.
That's normal. Been happening to me for a while. My TV signals constantly cut in and out
T3/T4 errors are like flat tires. Common, but still a problem and each case is caused by something different. Isn't your issue related to outages in your area?
I suggest making a post with technical data on your problem. Your last one was locked because the moderator thought you were asking for credit or talking about billing, which isn't allowed here. In your new post, include;
What model modem/gateway do you have? How does the coax get from the street to that modem? Splitters/amp/filters? Can you show signal levels?
Hi jaws222,
We don't want that to be your norm. At your convenience, please send us an email with your account details to Cox.help@cox.com. I'd like to check your equipment diagnostics and ultimately we may need to get a technician out to investigate further.

So I'm guessing cox we'll be down for 3 or 4 days at this point? Any idea what the issue is? Last time it went down for 3 days we were never told.
Hello jaws222,
I'd be happy to check any details for your immediate area. Please send us an email with your full service address for further assistance.
