Just got fiber optic. Nice.
The Huawei HG8245h modem-router given me by the ISP has four LAN ports.
(1) I hooked my desktop up to LAN1 of Huawei modem-router. Worked fine. Good ethernet connection, pretty good wifi from Huawei modem-router.
(2) To see if I could get better wifi, I hooked up my Apple Airport Extreme wifi router to LAN2 of the Huawei modem-router. It can't connect. Error message: NO DNS SERVER.
(3) Next I disconnected my desktop and I hooked up Apple Airport Extreme to LAN1 of Huawei modem-router. No Internet.
(4) Through trial and error, I set router mode on the Apple Airport Extreme to Bridge Mode and got it working.
(5) Then I connected my desktop to LAN2 of the Huawei modem-router. No Internet. Error message: NO DNS SERVER.
(6) Finally, I connected my desktop to one of the LAN ports of Apple Airport Extreme. Connection!
So, now I have my Apple Airport Extreme managing my LAN entirely, both wifi and ethernet. Speed is very good with both.
I should be happy, but I'm not. I want to understand why I can't have both my desktop and my Airport Extreme connected to LAN ports on the Huawei modem router.
MY QUESTION: I want to know why I can't get my ISP modem-router to assign any additional DNS addresses. It can assign only one. Do I need to change settings in my Huawei modem-router setup?
