Q: Wifi not connecting, but why?

what does this mean: Wi-Fi has the self-assigned IP address 169.254.102.185 and will not be able to connect to the Internet.  I have no problem connecting my iPhone to the same wireless internet.  Does it matter if I'm also connected directly to the ethernet cord? I wasn't able to connect to wifi prior to connecting to the cord.  Need wireless active so I can utilize wireless printers in area.

iMac, iOS 9

    If you turn off Wi-Fi, can you get an IP address via Ethernet?

    i tried but I am not sure what to do to follow what it said. I cannot simply restart the router- its a business.

    Apparently I'm able to get on the wifi but not the internet? The symbol is the baseball diamond shape with a computer inside it instead of the wifi symbol. does that help you?

    1. If the computer is connected through a switch to a cable or DSL modem, and the modem is not acting as a router, then only the first device to connect will get an address. You need to change the configuration of the modem so that it shares its Internet connection with all devices on the local network, or else connect a router.

    2. If there are other devices on the same network, and none of them can get an address, then the problem is on the DHCP server (most likely, the router.)

    3. If other devices are working normally, or if there are no others, the problem may be caused by a faulty cable or port on the hub. Switch connections with one of the working devices.

    4. If the Firewall is on, turn it off in the Security & Privacy pane of System Preferences. You'll first have to unlock the settings by clicking the padlock icon and entering your administrator password.

    5. Open the Network preference pane. If the preference pane is locked, unlock it. Make a note of your settings for the Ethernet service. It may be helpful to take screenshots of the various tabs in the preference pane.

    From the Location menu at the top of the window, select Edit Locations. A sheet will drop down. Click the plus-sign button to create a new location. Give it any name you want. In the new location, set up the Ethernet service with the same settings you used before. Click Apply and test.

    I am currently connected through an ethernet cable. I can access internet but not the company server.  I'm probably going to have to be added. However- this doesn't solve my wireless issue.  Please explain what the preference pane is for the Network as mentioned in #5. I didn't see a place to unlock...

     

    thank you so much!

    It looks like you're connected to another Mac that is sharing its Internet connection, not to a router. Most likely, it's the wrong network. You would have to find out from the network administrator which is the right one. You also have some pretty strange-looking network names in your vicinity, but I don't know whether that's significant or just somebody's idea of a joke.

    those are my old networks.  I named them that. yes, as a joke. So my neighbors would freak out.

    there are no other macs around here- all these people are PC people.

    I had to contact the network admin to get on their shared server, etc. so I'll just have him do it all. Not a huge fan of him but whatever.

    thanks for all your help. IDK why I couldn't just get on the wifi like I do with my phone. same concept right?
