    I found a thread here from a few years ago on a very similar issue but different circumstances so I thought it was best to start a new thread.

    My Macbook Pro (mid 2010) connects to my wifi network but there is no internet that comes through. The internet is not the problem as all other devices connect to it and use it.

    Here's the troubleshooting steps I have taken so far with no luck:

    * Rebooted the computer over a dozen times.
    * Rebooted the modem/router combo unit 2 times with the Mac off, then rebooted Mac.
    * Typed 8.8.8.8 in the browser to see if that loads because I read a suggestion to do it. Doesn't load.
    * Disconnected my Mac from the home network and connected to my phone's 4G hotspot. Still no internet.

    I then opened network diagnostics and under Network status, the first four things listed are in green. That's wifi, wifi settings, network settings, ISP. All green.

    Internet has a red button next to it and the word failed next to it.
    Server has a red button next to it and the word failed underneath.


    This is all the information I can think of at the moment to provide. If this is a DNS problem I have no idea how to fix that. But I don't know what it is and am at a loss. Any help would be appreciated, so if anyone who think they might know how to resolve the issue has more question, please ask me. If I can provide more information to help nail down what I can do to fix it, I'm all ears.

    Have you successfully connected via your phone's hot spot before?

    Have you tried to connect to your router with an ethernet cable? I've had a router fail even though it connected fine on my wi-fi network, just didn't pass through the internet anymore. It might have needed a hard reset, which is different from a reboot. Have you tried that with your modem/router?

    Thanks for the reply, yes, that's my number 4listed thing I tried. Hotspot connects but no internet. I have done a hard reset on both. Neither worked.

    If your modem/router is owned by your service provider, you can call them for support. They should be able to walk you through tests to determine what the problem is. They might help even if you own the modem/router.

    What I was trying to find out is whether, prior to this incident, you have ever successfully connected your MBP to the internet via the phone hot-spot. It may be that the failure to connect that way isn't related to this incident. If you have done it successfully before, then the most likely thing is that the problem is in your MBP.

    I take it you don't have an ethernet cable?

    That wouldn't do anything - 8.8.8.8 is a Google DNS server

    You can try to ping it from a Terminal window, though. Try that and let us know what it does.

    Also, take a screenshot of your TCP/IP configuration for that wireless connection in System Preferences
