Recently, I have discovered that my data usage has been excessive. Consistently, I have been using about 10-15 GB per day and about 300 GB per month. Now, as of mid-February, I am using 50-100+ GB per day and I am currently at 1.3 TB used.
I've worked in a data center and the IT industry for many years and performed the following:
-Reset my WIFI password to another cryptic and long password
-Enabled traffic monitor on my router. To elaborate, my router indicated I've used about 5.7 GB of data and Cox says I used 50 GB.
-Verified all attached devices to my router and mines and firmware upgraded.
-Executed nmap from external to my home IP and verified I don't have any dangling open ports.
-Reset my router MAC and reset my modem to pick up a new IP.
-Exchanged my Cox modem for a new modem.
Any ideas? My apps and devices are all monitored and everything is normal. 6 GB daily usage vs 50 GB and 300 GB monthly trend to 1.3+ TB?
It sure sounds like someone else is using the data associated with your account.
