Q: Internet Sharing stops working

So I used to share my internet from my laptop to my devices such as smartphone and iPad (from ethernet to wi-fi). It worked fine. But now, when I tried to connect my devices to the wi-fi produced from my mac, it connects, but when I try to open any browser it won't work, so devices are connected to wi-fi, but no internet connection. I've done everything to make it work again, from resetting my wi-fi setting (the one from internet sharing connection) and so on. I wonder if anybody can help me.

 

P.S.: Below is my wi-fi configuration, in case you need to know how it looks like.

    The usual problem when you seem to get a connection, but cannot get web sites to come up is DNS information is not available or is not valid. Without proper DNs settings, you cannot make any symbolic connections.

     

    If this gets you Apple, Inc:

     

    http://17.172.224.47

     

    then DNS is the issue.

     

    Non-responsive DNS server or invalid DNS configuration can cause long delay before webpages load

    Hello, thanks for your help. You mean opening that link from the device I connect to the wi-fi from my macbook? No it gets me nowhere. And I have a question, when sharing internet from ethernet to wi-fi, is my following wi-fi column correct with the 'self-assigned IP' or should it show another thing?

    Sorry, I cannot seem to see your graphic. Was it posted with the camera Icon on the forums?

     

    Self-assigned IP appears on the end device momentarily when it is starting up.

     

    In a properly operating system, that self-assigned IP is replaced in under a second with a proper IP Address provided by DHCP.

     

    On the Mac that is doing the Sharing, a self-assigned IP Address is what will always be seen from "inside". That is not important, as long as the end device shows a valid IP Address and a valid Router Address.

    Still can't see it?

    OK so my ethernet connection status: connected. So you're saying, it doesn't matter if my wi-fi status is showing 'self-assigned IP' while sharing the internet ? Then I don't get what the problem is... My iPad is now connected to the wi-fi produced from my macbook (which I am using right now) but doesn't get any internet connection. Ugh please

    You need to take steps to CREATE this network using the WiFi pane, and it Must show the correct name after it is created.

     

    So when you are sharing your Ethernet connection to your WiFi devices, and you go to inspect the sharing side (that would be WiFi on the computer doing the Sharing) it will be self-assigned and that is normal. The network-name will be the one you assigned, by default  the computer name of the Sharing computer. There will be no Router address.

     

    Then of course, you need to enter that password you created, or you get no connection from the remote device.

     

    On the other devices that are using the Shared connection, there MUST be a valid (not self-assigned) IP Address. There must be a reasonable-looking Router address (but it will not be the same one as on the Ethernet port on your Sharing Mac), and you must have something under DNS Addresses.

     

    Then when you enter:

     

    http://17.172.224.47


    You get connected to Apple main page.

    Ha! I think I get where my problem is: my IP address in my iPad is different from the one in my macbook, so are the subnet mask and router. Then, what should I do?

    my IP address in my iPad is different from the one in my macbook

    Each device MUST have a different IP Address -- that is how you tell them apart and decide what packets go where. Not only different, but it should be in a different range of addresses.

     

    so [is the] router

    That is a good sign, because when you create the shared network, it creates a new Router in software.

     

    Why don't you post the specific addresses. Most of these will be private, unroutable Addresses such as 192.xxx.yyy.zzz, 10.10.xxx,yyy or 172.xxx.yyy.zzz  anyway, so you are not giving anything away when you post them.

    yeah i know, but the one in my macbook starts with 134.130 something, but the one in my ipad is 192.168 something. Probably it's because I connected my devices to my friend's home's wifi...

    This is the default for the new little network you create:

    1. Router Address: 192.168.2.1
    2. Starting IP Address: 192.168.2.2
    3. Ending IP Address: 192.168.2.254
    4. Subnet Mask: 255.255.255.0
    5. DNS Server: 192.168.2.1

     

    These numbers will certainly be different from the Network provided by your Ethernet connection. But that is just fine, because you have a Router in software to translate the addresses to the ones needed on the rest of your Network.

    Everything matches with all the numbers you mentioned above. But still, it won't connect to the internet. Yes, my phone says it is connected to the network I create from my macbook, but when I open anything, like browser, it doesn't work.

    What happens when you do this.

    Then when you enter:

     

    http://17.172.224.47


    Do you get connected to Apple main page?  If not, what is the message?

    no, it won't connect to apple main page. The page just loads without end

    If that were a Mac, I would ask you to open System Preferences > Network > Wi-Fi and use the (diagnostics) button.

     

    I have no idea where that is in iOS.
