ContributionsMost RecentMost LikesSolutionsRe: High data usage Good to know because I was thinking about changing my router/modem after this just to be able to monitor where the data is going. Cox is unable to look this information up with the router/modem I'm renting from them. It might be worth it to buy our own modem even though they say they cannot give us tech support on non-cox modems. They evidently can't (or won't) give us tech support on their own modems so why not? Re: High data usage I changed my password a few days ago and left most devices offline. Only 1 computer, 2 smart tv's, an iphone and a ps4have been online.Hardly used any internet yesterday and still used 26GB. I have checked all options at cox.com and nothing will tell me where all the data is going, just that it is being used. It seems that something is awry with Cox. Re: High data usage I'm having the same problem beginning Dec 18th. My data has doubled from the last 2 months and I'm not doing anything different. We have a PS4, 2 iphones, a mini ipad, an iMac, and a few other small wifi devices. I'm also having to pay extra and have five more days to go! Yesterday, we used 26GB! I have no idea what's going on.
