From the Apple Support database article regarding network connection priority: If you connect to the Internet or a network in several different ways (using Wi-Fi or Ethernet, for example), you can change the order of the network port configurations your computer tries when connecting to the Internet or network. If there are multiple active ...

It's in your Network Preferences. Here's screen shots from 10.7.3. Access the settings from the gear at the bottom of the network type sidebar. Choose "Set Service Order..." to drag them into the preferred order.

If you wanted to connect to two different networks you could use this. So say you had an internal network which you had your own computers all linked to but were not connected to the internet, you could use one port to connect to this network. Then you could connect the other port to a broadband router/modem and access the internet on your Mac Pro. It's ...

First of all, connect the adapter and reboot. In many cases, it will solve the problem. You need to reboot because the adapter is not hot-pluggable. For the same reason, if you remove and re-insert the adapter, it won't work until you reboot. If you still have difficulties, I've found driver information while looking at the Thunderbolt to Gigabit Ethernet ...

Gigabit ethernet to gigabit ethernet. Next would be FireWire 800 to FireWire 800. Thunderbolt target disk mode is testing to be equivalent to FireWire 800 in target disk mode. It looks like the OS can keep a gigabit link fuller than target disk mode is able, even when the target mode link has vastly higher bandwidth available.

When your connections starts timing out, can you do arp -an in Terminal.app and see if you still have all MAC addresses in the ARP table? as in - your router's MAC address, or the host you're trying to ping? If you do (and you have the time before it starts working again), can you flush the arp table (sudo arp -ad) and then see if your router's MAC address ...

I recommand you to never use a configuration where you may have at the same time different interfaces up on the same machine. You won't have any easy knowledge and control of this dual connectivity. This may lead to huge difficulties to analyse even the simplest network trouble. This may also cause loops within company or personnal networks very hard to ...

From Super User: If I have two internet connections on osx, how can I use both to increase my bandwidth?: Short answer: no. With 2 links, you have 2 IP addresses. It can be done with some specific higher end NICs (e.g. Intel quad cards), but they will appear to the rest of the network as a single IP address in that mode. If the assumption is that you ...

If you are using VMWare or Parallels you can connect a virtual machine directly to one specific network interface (WiFi in the example) and use the other interface as the default for OS X: In the specific situation described in the question it may be too much of a hassle though.

StarTech makes the USB31000S, which is a USB 3.0 to Gigabit Ethernet adapter with support for VLANs, jumbo frames and checksum offloading. List price is about USD 55. These are based on the ASIX AX88179 chip, which has drivers for OS X 10.6 - 10.8 available (bottom of previous link). Any other product using this chip would also work.

You sure can! Open System Preferences, then go to Sharing and select Internet Sharing. Change "Share your connection from:" to Wi-Fi, and then in the box below it select Ethernet.

Here is a step-by-step guide for you: Temporarily disable any Firewall/Internet Security solution/packet filter on your Mac (like LittleSnitch/Hands Off!/Kaspersky Internet Security etc.) Connect to the administrative interface of your router with a working Mac. Make a note of the internal interface (probably 192.168.0.1 in your case) If your router uses ...

I've seen this happen when the local DNS server has DNS caching enabled, but doesn't flush the cache often enough (or at all). You can set your Host Name/Computer Name to a static value using scutil in Terminal. This means that your Mac will no longer change it's name automatically, so it's important that there are no other machines on your network that ...

The MAC Address is unique and a property of the actual network hardware (although it can be spoofed). So your adapter has its own MAC address, as does the the network interface in a Thunderbolt display, and the Wi-Fi in your MacBook Air. Different Thunderbolt to Ethernet adapters will have different MAC addresses, but moving one between different ports ...

It's not USB 3.0, but the Belkin F5D5055 USB 2.0 Gigabit Ethernet adapter is supported out the box by 10.7 (haven't checked 10.6) and delivers better performance than the Apple 10/100Mbps adapter. I can get speeds of around 35MB/s with my mid-2011 i7 Air.

I had this problem, too, and an Apple Support call and Genius Bar visit later, I had the answer: if you're using Network Locations that preexist your Thunderbolt display, it doesn't seem to auto-add the possibility of "Display Ethernet" to your available network ports. To solve this, either: Create a new Location in your Network system preferences. It will ...

Could you first check that you are really using the network interface you should: ifconfig -a Could you look at the output of the following commands (if en0 is the network interface name of your Ethernet card): netstat -I en0 To help locate the problem could you make a specific Location with just your Ethernet card activated and if possible only using ...

I just installed menumeters. If you go into the preferences for MenuMeters it is possible to add a network icon to the OSX menu bar. Clicking on the icon, indicates the current network (i.e., wifi or Ethernet). This is a reasonable solution, but it still requires you to click on the icon to see whether ethernet is connected.

If this is recent, you may be the victim of a bad malware protection update from Apple. They have posted a support article explaining how to check if this was the cause, and how to fix it. First, check your version number While pressing the Option key, choose System Information from the Apple menu. Expand the Software section and select ...

Time Capsules are Gigabit Ethernet routers. This means a top speed of 100 MB/s over cable (but is pretty unlikely). It will however be comparable to the speed of USB2, so I think you should try it before dismissing Ethernet.

I'd suggest using rsync from the terminal. It may still be slow, however: It should be faster than finder. You can stop the transfer any time. It will resume from where you left the next time you issue the same command. So, it should both reduce required time and also make it possible to stop it and resume if you actually need to use your computer. sudo ...

I've had this problem for a long time now (beginning after an upgrade to Mavericks) and, after months of research, I think I finally found a fix. First of all, there are quite a number of people with the very same problem in the Apple forums: Why in OS X Mavericks internet is so slow? Mavericks network issue So this is a known issue and I really don't ...

This is fixed in Mac OS 10.8.3. In MacOS 10.8.2 although I faced an issue: I have a version from Delock running driver V1.3.0 (but V1.2.0 showed exact same behaviour). Adapter runs fine on first connect. If unplugged and plugged in again it will not work unless I reboot. Best solution I found is to reload the driver by hand. That saves you at least the ...

Your best bet is Apple's Thunderbolt to Gigabit Ethernet adapter. There are also assorted USB ethernet adapters available from various sources (including Apple), including a few Gigabit ones that use USB 3.0, but the Thunderbolt one will likely have the best performance, so unless you're using both Thunderbolt ports already, that's the better choice.

If you have somehow modified the default service ordering, you can set it again in the network tab using the gear. This makes the Wi-Fi inactive for internet routing whenever you connect the cable. What you ask is scriptable if you know some programming, but there isn't a simple trigger to actually turn the Wi-Fi radio off at the user level of the OS.

You should be able to do this via Ethernet or wireless, depending on whether you want to buy a wireless dongle for your TV or whether you have the Ethernet adapter for your MacBook Air. If you have the USB Ethernet adapter, you should be able to follow the instructions found here: Set up the Sharing -The first step is to set up sharing on the host Mac. ...

192.168.1.15/24 is a so-called slash notation, which specifies both the IP address and the network mask at the same time. It's an alternative but shorter notation, which says: your Mac's IP address should be set to 192.168.1.15 and the network mask to 255.255.255.0. In addition to that, you will need to enable the tftp server on your Mac. To do that, look ...

Wired ethernet (gigabit on both ends) will be every bit as fast as Firewire to Thunderbolt and without the cost of the adapter. Depending on how noisy your Wireless environment is, you might have a limiting factor in the speed of the old iMac hard drive that's lower than WiFi throughput, but wired ethernet is so much more reliable, I'd do that if you can. ...

Below is a network diagram based on what I have read thus far. I have made some assumptions about the IP numbering conventions, but that will have no effect on the overall scenario. I am assuming that you are using two different subnets rather than 2 different classes of networks. But, either way, you have two very different network IP addressing schemes ...

First, I see dropbox running in your menu bar; have you disabled that, yet? Second, try removing any other startup/login items. Look in: Login: ~/Library/LaunchAgents/ ~/Library/LaunchDaemons/ System Preferences > Users & Groups > Login Items Startup: /Library/LaunchAgents/ /Library/LaunchDaemons/ /Library/StartupItems/ ...
