OrbiRBR50 Ethernet Connectivity Problem
I've just recently upgraded my router to the OrbiRBR50 from an older Nighthawk7000 that died during a thunderstorm surge. The wifi and satellite set up was easy and seamless. All wireless devices in t...

My desktop Apple Mini(Yosemite 10.10.5) previously had an ethernet connection with the Nighthawk is now having difficulty recognizing the ethernet connection with the new Orbi. Its wifi connection is fine but I prefer the ethernet connection for speed. The ethernet in setting says no connection.
One simple test is to power off the internet modem, unplug the Orbi, and plug in the Mac with the ethernet cord. Power them up (modem first), and the Mac should get an IP address from the modem and be connected. If the R7000 was fried while the Mac was connected, MAYBE the overload also fried the Mac's ethernet port?
(Since this is desktop instead of a laptop, connecting it to a different router is not a trivial task.)

Hello CrimpOn, are you suggesting that I connect my Mac directly to the cable modem via an Ethernet cord in order to get the IP address from the modem?
Yes. The modem waits for something to connect and when whatever device it is makes a DHCP request for an IP address, the modem sends the request to the ISP and returns the answer to the device. Doesn't matter if it is a computer, a router, or whatever.
So, when the Mac is plugged directly into the modem and the modem is turned on, the Mac should get an IP address and be connected to the internet. We know the modem works because the Orbi is working. We know the cables are good. We know other devices connected to the Orbi work. If the Mac doesn't work when connected directly to the modem, then the ethernet port could be defective.

Thank you, Crimpon. The MacMini still does not show ethernet being connected with the ethernet cord directly connected to the modem. I think we have narrowed down the problem to the Mac itself, whether it be the port or some other configeration issues.
Does the mac Mini get an IP address via wireless?
Alternate solution if you cant get the LAN fixed, find a USBtoLAN adapter.
Yes you can connect your Mac directly to the modem via ethernet and it should get an IP address and internet access.

Thank you, FURRYe38. I think we have narrowed down the issue to the MacMini itself since connecting the mac directly to the modem did not solve the problem. The port was probably damaged or taken down along with the old R7000. Someone from the Apple support community is suggesting resetting the Mac's SMC and NVRAM. I will have to see how involved that route is.
Yes, seems like it. Hopefully the LAN port can be recovered. If not, see if Apple can fix it. Short term, find a USB to LAN adapter as a temporary solution if you need LAN support.
Good Luck.
