Good info. Thanks.
I'm not sure why you want a static IP address, Time Warner wasn't static and I used my RR on TW for over 2 years in joyous bliss without it ever changing IP numbers. And, static IPs come with an awful cost, am I right?
And it shouldn't be so hard to get ATT to be able to reveal if they are IPv4 or IPv6, but it is. Like pulling' teeth.
Anyway, I have found another ham in my club who believes he may well have some answers. In my case, I have the ATT combo router/modem and my own modem is plugged into it. Up until now, I (with a ton of help for a different ham) tried using both my router and plugging directly into the ATT router. Both attempts failed. But my new aquaintance just told me that we should plug directly into the ATT router. We will be doing that and more in the next week and if I come back successful, I will, we will promise to share what we did.
I have to say this at this point. It should not be so hard to make these RRs work. With all of our brains and technology, we somehow have failed to get our computers and our radios to talk to one another. I shouldn't have to hire a tech to get it to function, and neither should you. But here we are.
All for now. I will report back soon.
