Can you please just fix my internet without trying to sell me cox home care every time you have an outage in my area.

It sounds like you might have an older modem.  Unfortunately, cox is so unethical that they will charge you for a higher speed then your modem supports.  Even though they can clearly see the model of modem that you have on the network.  The old Cox is gone, they've become criminals.

One other possibility (kinda remote though).  When I first realized there were data caps, I enable bandwidth monitoring on my cisco router.  Little did I know that this limited my speed to 25mbps.  Make sure you didn't do something similar on your router.

The funniest part.  I'm a very heavy user and I didn't notice for a long time.  I ran at 25mbps for weeks.  That's when I realized that I'm paying for more speed then I need.

To get a handle on where my data usage was coming from, I run custom firmware on cisco router with a custom per device bandwidth monitoring app that runs on the router.

This is the *ONLY* way a consumer can accurately see what is using bandwidth on their network.  That is what makes Cox's data cap literally criminal.

Without properly informing the consumer of their data usage, Cox is just stealing money from their customers. And, no, the crappy bandwidth meter doesn't count.  It's a joke.

With your cell phone data limit, the actual device that you hold in your hand tells you what your data usage is.  And it tells you what specific apps use that data.

The actual device that you use with cox, the cable modem, does nothing of the sort. Call cox and ask them to tell you which devices are using the data on your network, they can't and won't.  They will just try an upsell you.

Criminal ... Cox should be ashamed.
