My wife is over in Denmark by herself\u00a0at the moment but wanted to share her in room internet connection (a cabled Ethernet connection) to her other devices over Wi-Fi. She had recently upgraded her MacBook Air to Mountain Lion (Mac OS X 10.8) but had used internet sharing on that computer in the past on earlier versions of the operating system.<\/p>\n

Anyway, attempting to setup internet sharing proved a little challenging and presented issues. Normally, you should just be able to go via the Sharing applet in System Preferences and choose the Internet-facing connection and to which other network connection you want to share. In this case, we wanted to share from the Thunderbolt Ethernet adapter to the Wi-Fi adapter. Unfortunately, it’s not enough to simply do that it seems after many failed attempts to get it to work – you actually need to hard code an IP address for the Wi-Fi interface on the Mac doing the sharing (at least that is what worked).<\/p>\n

This is what we did:<\/p>\n

    \n
  1. Undo all network sharing,<\/li>\n
  2. Go into System Preferences<\/strong> and then Network<\/strong>,<\/li>\n
  3. Click on Thunderbolt Ethernet<\/strong> (or whichever network interface you wish to share from) then click the Advanced<\/strong> button,<\/li>\n
  4. Click the TCP\/IP<\/strong> tab and take note of the Router<\/strong> address,<\/li>\n
  5. Click the DNS<\/strong> tab and take note of the DNS <\/strong>addresses and then click\u00a0OK<\/strong>,<\/li>\n
  6. Click on Wi-Fi<\/strong> (or whichever network interface you wish to share to) then click the\u00a0Advanced<\/strong> button,<\/li>\n
  7. Click the TCP\/IP<\/strong> tab up the top,<\/li>\n
  8. Next to\u00a0Configure IPv4<\/strong> select\u00a0Manually<\/strong>,<\/li>\n
  9. Next to\u00a0IPv4 Address<\/strong> type in 10.0.0.1, 172.16.1.1 or 192.168.1.1 (so long as it doesn’t match the first number in the router address of which you took note in Step 3),<\/li>\n
  10. Next to\u00a0Subnet Mask<\/strong> type in\u00a0255.255.255.0<\/strong><\/li>\n
  11. Next to Router<\/strong> type in the address noted in Step 4,<\/li>\n
  12. Click the\u00a0DNS<\/strong> tab,<\/li>\n
  13. Type in the DNS addresses noted in Step 5 (just click the plus symbol underneath when you want to add a new one),<\/li>\n
  14. Click\u00a0OK<\/strong> then\u00a0Apply<\/strong>,<\/li>\n
  15. Go into\u00a0System Preferences<\/strong>\u00a0and then\u00a0Sharing<\/strong>,<\/li>\n
  16. Click on\u00a0Internet Sharing<\/strong> in the list on the left,<\/li>\n
  17. Next to\u00a0Share your connection from<\/strong> choose your connection from which to share (in my case, Thunderbolt Ethernet<\/strong>),<\/li>\n
  18. Next to To computers using<\/strong>, tick the network interface to which you want to share the internet connection (in my case,\u00a0Wi-Fi<\/strong>),<\/li>\n
  19. If you are sharing to Wi-Fi then click the\u00a0Wi-Fi Options<\/strong> button (otherwise skip down to Step 22),<\/li>\n
  20. Give your network a suitable name, select appropriate security (WPA2 is available otherwise WEP) and provide a password,<\/li>\n
  21. Click\u00a0OK<\/strong>,<\/li>\n
  22. If you are prompted to start\u00a0Internet Sharing<\/strong> accept the offer otherwise tick the box next to\u00a0Internet Sharing<\/strong> on the left.<\/li>\n<\/ol>\n

    Once done, you should be able to hook up your other devices and get a connection to the web and this certainly got things working on the other side of the world after a lengthy LogMeIn<\/a> and Skype session!<\/p>\n","protected":false},"excerpt":{"rendered":"
