See here for instructions on changing the MAC address. A MAC address is a unique hexadecimal number that all network devices have. Think of them as finger marks for computers. Your router has one and the network card in your computer has another. Cox and most cable broadband ISP use something called DHCP that gives out IP addresses automatically based on their MAC address. Different MAC means different IP. That is why you got a different IP when connecting direct to the modem. That is also why you can clone your routers MAC to your PC's MAC to get the same IP, or at least different then the one cached to the router.
However I would like to state this is a work around solution. Without knowing what triggered the first black list there is no knowing how long this will work. It's DHCP which changes the IP address perhaps every 24 hours(usually not though) so you might eventually get the same blocked IP again.
OH! BTW, see my thread on the R7000 router. You need to update the firmware because of a known vulnerability. See here for instructions.

I actually follow most of that but I didn't realize the relationship between the MAC address and the IP, although it makes sense now that I realize I got another IP when I replaced the router connection with my computer . I understand this is just a work around. I'll try it for testing purposes and get back to the bank to see if they can do anything. Not sure if they'll be able to help or not but I'll try. I do need to update the router firmware; haven't logged in to the router as an admin for quite sometime. I'll post again once I try everything out and let you know what happens. Thank you for all the input. I'm still a novice but glad to learn a little more each day.

Let us know how it goes. Good luck!

I was able to login to my router and update the firmware. Good idea! Long overdue in my case. I had some difficulties with the MAC cloning, although your instructions were right on target. I saw exactly what you indicated when I was logged into the router but I think I didn't reboot something properly. But no matter, since as you say it really is a work around. The IP I got originally should work but the bank is blocking it for reasons unknown.
So, I ran a tracert while on the router and got blocked and then plugged my laptop directly to the modem, getting a new IP, and ran the tracert again, which did not get blocked. I sent that info to the bank so they could see it is their server (or more likely their web vendors server) that is doing the blocking. I'll follow up with them next week. I can't believe I'm the only one who has ever had this problem and they should learn how to fix it.
