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 ...

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 ...

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.

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 ...

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.

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 ...

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.

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 ...

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.

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.

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 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.

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 ...

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 ...

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.

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. ...

Only if the application itself supports this. If it does, it will have config files that allow you to specify either an IP address to bind to, or an interface name to bind to. You would then find out your internal IP address by checking the Network control panel or the interface by checking ifconfig through the terminal. As far as I know.

I'm guessing here, but it your network settings may have the ethernet interface prioritized above the AirPort (this is the default setting), meaning that when both are connected it'll try to reach the internet through the ethernet connection. You can check this easily be looking at the order the network "services" are listed in the sidebar of the Network ...

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/ ...

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 ...

Even with multi-homing on iOS 7 starting to allow traffic over LTE and WiFi simultaneously, there isn't a good way to accomplish this on OS X Mavericks and lower. I have run Link Aggregation on macs since 10.4 and it's really nice when you have a gigabit switch. You will need a switch that runs LACP and two physical ethernet ports like is typical on G4 ...

Got it. All you have to do is add multiple Ethernet interfaces in Network Preferences. And then just configure each one to the correct settings and you're set to go. I tested this by hosting two different websites on two different IPs by multihoming my iMac and it worked!

It seems like this issue at least for me may have had nothing to do with the thunderbolt connection. Rather it was a more mundane networking issue. I.e., when I moved between networks, network settings needed to be reconfigured. Techniques like renewing DHCP lease and using the "assist me" procedure in network preferences seemed to be sufficient for me to ...

If you connect the Thunderbolt-Ethernet adapter and connect an ethernet cable, the MAC address immediately appears in the Network -> Advanced -> Hardware tab.

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 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 ...

There is a great deal of information here on the troubleshooting and diagnostic end of things, but sometimes when troubleshooting it's fun to return to basics and question some assumptions. As I mentioned in a comment, this looks very much like a QOS router kicking in due to your machine temporarily exceeding some bandwidth or packet rate cap. What if you ...

but will it affect speed of LAN transfers? Well, you can choose which one would be preferred (by dragging it to the top in the Network preference panel): As far as I know you cannot get a FASTER transfer by using both at once...
