1.6 TB usage in a day

vega23 Hi, I'd like to look into this for you. Please send am email to cox.help@cox.com and include your full name, address and a link to this forums post. 

Did you get any definitive answer from them ? or they are simply blaming on you ?

Support is useless.  They have no concept of how much data 1.6 TB is.  I was thinking there is an edge case where the old modem is glitching.  It was 10 years old.  So replacing it with a new one at least lets me rule that out.  Also if someone had hacked the wifi connection there is a new pw now.  I really just want to cancel but have no choice it's the only highspeed in my area.

There's something ironic about complaining about the lack of technicality of support. When you wouldn't need that support if you had the technical ability to use your own equipment. So yes, Cox support is bad so doesn't that mean you should stop using them? Even if they had more granule modeling and control of bandwidth. Would you really trust it? I know they say they test it through a third party but we see issues here all the time. If nothing else, you should have your own system to monitor bandwidth use so you can fact check theirs. Keeping honest people honest as they used to say. There are so many other reasons that you should not use ISP equipment and use your own. It's usually cheaper since you don't have to pay for the gateway. It's usually better performing because a lot of the design of the gateway is put into reducing support call volume and using automation to do things so they don't have to write support documentation on how to do it. If you make the router automatically select Wi-Fi channel, you don't have to worry about showing customers how to change the Wi-Fi channel. Last Cox uses. Comcast's x 1 platform so not only does Cox not have direct control over changes and patches but it is unknown how it will work with the Cox spectrum transition. Now is really the time to buy your own router. Especially with everything scary going on and cyber security right now. The X1 platform because it's so widely used makes a huge Target. Granted it's backed up by Comcast money, but sometimes it's still better to be a smaller weaker Target than to have a big hitbox.

Hard to follow thru with a gauntlet tossed to the floor of " I am leaving Cox " when they are often the only cable service and DSL is hardly a equal and wireless services often have latency issues. Need to break up COX like they did with Bell Phones, and make Baby Bells.

Most data issues has nothing to do with a PC, phantom data spikes often happen from streamers and cameras. I have a router that logs data and I can see the data on my wifi with UNIFI in my house, I see massive data via my security cameras when my wife pokes in to look

I got around 90 GB usage today as well, when I have not used much. This is ridiculous and they are simply blaming it on us. I cannot see this current cycle usage also. Last cycle I'm able to see with categories.

Yes the support is the worst! When I called they said they raised a ticket, escalated it and gave me a ticket number. When I checked the status of the ticket by mailing them, I came to know there was no ticket raised at all and they are definitely not willing to raise a ticket. I cannot see my current cycle usage as well and it's so much irritating. 

haripriyar, we are not aware of concerns viewing data usage online or via our app.  If you are unable to view your data usage.  Please email us at cox.help@cox.com for support.

Switch to the Current Usage tab.  The Usage cycle row indicates the range of days covered.  If today is the first day in the current cycle, there's no data to view yet.  Check it again tomorrow.   

There are several different types of ticket numbers. More than likely, they submitted a remedy ticket, and the first level of support won't be able to see it. Did the ticket# they gave you start with CUI?

Yes, I made an educated guess that swapping the modem would fix it.  Because my old modem was 10 years old I decided to just scrap it and buy a new one.  Usage has been back to normal for the past 3 days.  No way to know what the true root cause was.

If it happens again id have to assume its hacking and take additional security precautions on my end.  Had I listened to Cox chat support I would have paid extra for unlimited data when under normal circumstances I use <10% of my monthly quota.  I hope this thread can help others in a similar situation, given how incompetent / greedy their chat support has shown to be.

Hi! Which category in current cycle usage showed the spike? 
please help me on this because my usage is still showing very high when I’m not even watching anything for more than 3 hours.

I'm at just over 6TB of usage for the cycle, 5/18 - 6/17. 

Do you use a VPN? What about security cameras, or Amazon Echo/Alexa?

VPN caused the spike.  I don't have Alexa or cameras.
