The Apple USB Ethernet Adapter is a simple, one-piece external adapter that plugs into the USB 2.0 port of your MacBook Air to provide 10/100BASE-T performance. Simply plug your Ethernet cable. Apple refers to this adapter as a 'camera connection kit', but it can connect any compatible USB device to the iPad. You can use this adapter to connect a wired keyboard, MIDI devices and, yes, USB-to-Ethernet cables.
Does the MacBook Air really not have an Ethernet port? How can you connect to wired networks? Indeed, MacBook Air models really do not have an onboard Ethernet port. However it is possible to connect to wired Ethernet networks with an adapter.

For the 'Mid-2009' models, Apple provided the external Ethernet adapter free of charge.
For the 'Late 2010' models and 'Mid-2011' models, Apple again provided it as a US$29 option. For the 'Mid-2012' and subsequent MacBook Air models, Apple offers an optional Thunderbolt to Gigabit Ethernet adapter for US$29. Apple Authorized site sponsor sells both the Apple USB 10/100Base-T Ethernet (MC704LL/A) and the Apple Thunderbolt-to-Gigabit Ethernet (MD463LL/A). Site sponsor sells third-party USB 3.0 to Gigabit Ethernet like those shown above. Is an external modem available for the MacBook Air?
Apple used to offer an external Apple USB Modem (56.6k v.92) for US$49 (MA034Z/A), but it no longer does. Just like all the other Intel-based Macs, Apple does not offer an internal modem with the MacBook Air, either. However, third-party USB modems designed for travel are available still. Photo Credit: USB Modems - StarTech (Left), Zoom Telephonics (Right) Third-party modems are compatible with MacBook Air models running Mac OS X 10.5 'Leopard' or Mac OS X 10.6 'Snow Leopard'. OS X 10.7 'Lion' and later versions of the operating system do not support modems at all.
Site sponsor offers USB modems compatible with the MacBook Air when running a compatible version of Mac OS X. Is the 'MagSafe' power connector that ships, or shipped, with MacBook Air models also compatible with the MacBook and MacBook Pro? The 'MagSafe' or 'MagSafe 2' power connector that has shipped with each MacBook Air model only provides 45-watts of power, and as such, cannot power a MacBook or MacBook Pro model, which all require more power.
Additionally, the 'MagSafe' power connector for the original, 'Late 2008' and 'Mid-2009' MacBook Air models is rotated 90-degrees to save space. A 'regular' MacBook 'MagSafe' power connector will provide power to these earlier MacBook Air models, but it won't fit when the MacBook Air sits on a flat surface.
On the other hand, a regular MacBook 'MagSafe' power connector can provide power to the 'Late 2010' and 'Mid-2011' MacBook Air models. The 'Mid-2012' and subsequent MacBook Air models have a 'MagSafe 2' power adapter and can be powered by its own power adapter or the 'MagSafe 2' power connector from a Retina Display MacBook Pro. The MagSafe 2 power connector is not backwards compatible with earlier power adapters, but an earlier MagSafe power adapter can be used to charge a MagSafe 2-equipped MacBook Air with the Apple MagSafe-to-MagSafe 2 from Apple or site sponsor (MD504LL/A).
The problem seems to be the Gateway entry of 0.0.0.0 it should only list 192.168.0.1 Default Gateway.: 0.0.0.0 192.168.0.1 Hey, I went to Network ConnetionsLocal Area ConnetionPropertiesIPv4 and tried 2 things: 1. Leave everything obtain automatically but went to 'AdvancedDefault Gateways Add: and I added 192.168.0.1 2. Manually enter IP address and DNS servers as follows: IP address 192.168.0.2 Subnet mask. 255.255.255.0 Default Gateway: 192.168.0.1 Preferred DNS 192.168.0.1 Alternate DNS Server 192.168.0.2 Neither of these options helped. When I bring up a new 'ipconfig' it still says: 'Default Gateway.: 0.0.0.0 192.168.0.1' Also, weird thing, when I hit ok and close properties, on the Local Area Connection Status window, next to IPv4 Connectivity, it says 'Internet' for about a minute before changing to 'no internet access', and further, I am getting a LOT of bytes both sent and received under activity, but no internet. Thanks for any more help you can provide. Have you check your proxy settings?
Check for malware/virus. Check for viruses, malware, none detected. How do I change proxy settings? This is not just an issure with my web browser, nothing requiring access to the internet can access the internet, even though it says that I am fully connected to the internet. Even the 'Local Area Connection Status' windows says 'Internet' available next to IPv4 connection. Also, my ipconfig now has the default gateway listed exclusively as 192.168.0.1, no more 0.0.0.0.
