Have you bypassed the router, if you have one, and plugged your computer directly into the modem? Are you using one of our modems or do you have a 3rd-party modem?

I am having the same problem. I have bypassed the router with the same problem. I have used 2 different routers that generated 2 different IP addresses from Cox. Both have the same problem. They are black listed on dnsbl.spfbl.net. The error has something to do with a mail server. Since this is a residential account, I am not running a mail server. Since this is impacting multiple Cox customers on multiple cox IP addresses, can’t Cox investigate and fix?
- @NickL,
I know this has been frustrating. Can you try doing an ipconfig release renew (with the router attached)?

Cox Support Forums ModeratorDo you mean with the laptop wired to the router? Use the windows command prompt? I tried to do this while on WIFI through the router interface and it never reconnected. I had to do full restart of everything to get back to where I was. I am way outside of my league here and I am afraid I will break things to the point I can’t connect at all.
Also since already happened to me on two different Cox IPs, I am not sure I will get a different resultyes, this has been incredibly frustrating. I am paying for a service that I can’t fully use....
if you answer my questions above, I will see what I can do....
- @NickL,
Yes, hardwired directly into your router. In the Command Prompt, enter “ipconfig/release” then press [Enter] to release your computer's current IP Address. Enter “ipconfig/renew” then press [Enter] to renew your computer's IP Address.
