I just arrived from the US to Hong Kong. In the Hong Kong airport, my iPhone connected to the wifi & Internet with no problem. Now, I'm in the house where I'll be staying, and all of my devices (iphone, ipad, macbook pro) connect to the wifi with no problem, but I can't get to the Internet. Other computers (Window + Mac, iPhones, iPads) in the house are working just fine.

 

I've been through the diagnostics on the MacBook several times. It just says the network connection failed, but no clues as to how to actually troubleshoot & fix it. I've poked around & tried a few different settings, but I'm just shooting in the dark. Any help would be greatly appreciated!


MacBook Pro, OS X Mountain Lion (10.8.1)

    Double check your TCP/IP settings in system prefs---->network. Click advanced on wifi and make sure you're TCP/IP connection is set to DHCP and check the DNS tab has no entries in it (ie getting DNS from the router). If this looks normal, run the network utility and see if you can PING google.

     

    Sometimes with cetain macs, the encryption and/or channel the wireless router is using can cause the connection to fail. Escpecially if the router is running on 5ghz instead of the usual 2.4ghz band.

    Yeah dont do all that

     

    -Iphone>settings>general>reset>reset network settings

     

    -Reset the router by unplugging the power and plugging it back in

     

    -thats a 99% fix for that And make sure the router has WPA2 for security

    Hi

     

    Can someone please help me?

     

    I tried your method of resetting the network settings, security encryption set to WPA2, renew lease, forgetting the network but all these fail.

    I have also tried Enabling the WMM, placing the MAC address of the iPhone user to the connection control list,  it do not work at all.

     

    Can someone kindly advice me on how can I move forward to get it work?

     

    Thank you so much

    Is there any restrictions or rules of maximum devices on your router?

    Check your router settings if you have any like DHCP filter rules or IP restrictions.

    Hi all,

     

    I have managed to solve the problem and it has got to do with network range of 169.254.x.x

     

    If you guys happen to have ip addresses in that range, please change it to another range.

     

    At your router LAN settings, give a different range of ip address (such as 10.10.x.x/24, 192.168.x.x/24) while WAN settings would be provided by your ISP provider. The router would do a NAT route by translating private address to public address and then connect to the Internet

     

    And it should work!
