I have internet access but I noticed that in System Preferences/Network, although the W-Fi status is "On" this statement is below: "Wi-Fi has the self-assigned IP address XXX.XXX.X.XX and will not be able to connect to the Internet." There is a yellow dot preceding the "Wi-Fi / Self-Assigned IP" icon on the far left of the System Preferences/ Network window. The Network Diagnostics shows all the items under Network Status as green. My modem does not have a router. It is behind a Verizon (ISP) router that I do not physically own or have access to. I can only access the settings at: "my home.modem manufacturer's name.com". Is this still a problem that needs correcting? Thank you.
UPDATE: My ISP says: "Okay that's the issue as it is a 6100 modem it does not have a feature or wireless option you need to get one wireless router from ups store...I will send you a free modem which is an advanced one.."
