I apologize if this is a stupid question, but I'm not very tech-savvy. Using a iMac (21.5-inch, Mid 2010), running El Capitan version 10.11.6. Router is Amped Wireless ATHENA, High Power AC2600 Wi-Fi Router with MU-MIMO (RTA2600).
I have a Mac computer that is hardwired for Internet (I have a cable plugged into back of computer). My husband also has a computer hardwired, which is not a Mac. We also have wireless service.
Earlier we had to reboot the modem and router. Now, my husband's computer will work with Ethernet, but mine will not. I can only get connectivity with my Mac via wireless (192.168.X.XXX). I've checked network settings and it says Ethernet is connected but cannot connect to the Internet.
Why not? It is setup as DHCP. I have no clue what to do. Again, none of this happened until we rebooted/reset the router and modem.
Any help would be greatly appreciated!
I did do a "renew" as suggested and the IP address came back as 169.254.xxx.xxx. I also noticed the "router" field is blank. Subnet mask is populated.
