Gigabit Ethernet connection

Is the only current option for an Ethernet connection for a MacAir the USB adaptor? I've seen where the Sonnet thunderbolt adaptor will be coming but I can't find it for purchase. I'll be using my MAP mainly connected to a hard line and fear it's going to be too slow. The laptop isn't an option due to travel.

The Sonnet Thunderbolt Adapter is not available yet.
But unless you have a really super speed internet connection or are doing a lot of machine to machine transfers then the gigabit over 10/100 speed of the Apple USB adapter.
The Apple Adapter is rated as 10/100 Mbps. The USB 2.0 port itself is rated at 480Mbps though it has a lot of overhead. Both of these should be faster than your ISP connection unless you are very lucky.
802.11g WiFi speeds should be comparable to the USB Ethernet speed.
802.11n WiFi speeds could be faster to the USB Ethernet speed.
Again, both of these should be faster than your ISP connection unless you are very lucky.
The 10/100 Mbps speed from a practical standpoint will only make a visible difference for machine to machine transfers where the other devices are 10/100/1000 Mbps capable.

Gigabit ethernet connection to existing Airport wifi?

I have a new iMac with a Gigabit ethernet port. If I want to connect it with a gigabit ethernet cable to my 2010 Airport Extreme box, and therefore to my existing wifi network:
1) How do I determine if the Airport Extreme [802n (4th Generation)] is gigabit ethernet capable? Airport Utility does NOT tell me if it is 802.11n (Gigabit Ethernet) or 802.11n (Fast Ethernet).
2) Will the gigabit ethernet's INTERNET connection be faster on this iMac than on the other wireless-connected devices? In other words, is there a real internet advantage to using gigabit ethernet connection?

Does this mean a Mac on Ethernet can see all devices on an AE wifi network, including a USB printer connected to the AE?
Yes, wireless and wired devices are on the same network. Wireless and Ethernet are two doors that open into the same room.
Does connecting a Mac with gigabit ethernet prevent/replace a wireless connection?
The Mac can connect using either wireless or Ethernet, but not both at once. If you connect an Ethernet cable to the Mac, that connection will become the active connection.....assuming that you are using the Mac's default settings. If you want to use the wireless connection on the Mac, then you will need to physically disconnect the Ethernet cable.
I guess I'm asking about the advantages and disadvantages of connecting a Mac via gigabit ethernet.
Advantages......Faster speeds on your local network between network devices.....no speed loss up to 330 feet or 100 meters......and there are no wireless interference issues in a wire. A wireless signal loses speed the further it gets from the router and with any obstruction that it hits. Other wireless networks around you tend to generate noise that will also slow down your wireless signal.
Disadvantages....you have to run the Ethernet cable.

Using Xsan to carry data over dual gigabit ethernet connections?

A designer (mostly non-technical) colleague of mine has claimed that Xsan transfer data (not metadata) over dual gigabit ethernet, in lieu of Fiber Channel, with metadata flowing over a third ethernet. Is this true? Has anyone done an install in this manner? I can't find any reference of this, anywhere.
If anyone can help shed some light on this, I would appreciate it!
Thanks,
Ben

If you're planning on connecting to the SAN in this manner, be aware that the amount of bandwidth is MUCH smaller than fibre channel. (That's why X-SAN used fibre between clients and the SAN)
So... if you're thinking of pulling uncompressed HD through ethernet (even Dual Ethernet) you're going to be woefully disappointed.
Having said that, we regulary connect dozens of "story editors" to our X-SAN via a single gig E "reshared" connection. The secret is that we ONLY use "off-line RT" media for this connection. We've locked out our "Full Res" media from this kind of connection because it will only jam up the system and bring our internal system to it's knees. I would regard this kind of "tapping in" to the SAN as a "secondary" method, not your primary way of accessing the media.
Good luck.

How do I extend an existing wireless network with a 2nd time capsule? I want to tether them with a gigabit ethernet connection.

I am having trouble with extending a wireless network using 2 timecapsules (1 is 1 terrbyte hdd, the other has a 2TB HDD.) The first one is connected to the WAN (cable modem) and our LAN. I would like to connect the 2nd one to the ethernet LAN and have it 'rebroadcast' the 1st ones wireless n network in order to expand the overall range of the network. Your help is very much appreciated.

Suggest that you download and install the much more useful AirPort Utility 5.6 for Mac OS X Lion.
I assume that Time Capsule 1 is operating correctly at this time.
Open Macintosh HD > Applications > Utilities > AirPort Utility 5.6
Select Time Capsule 1 and click Manual Setup
Click the Wireless tab below the row of icons and make a note of each of the setttings on this Wireless page.
Make sure that the Ethernet cable is connected to the WAN "O" port on Time Capsule 2.
Open up AirPort Utility and select Time Capsule 2 and click Manual Setup
Click the Wireless tab below the icons and enter the exact same settings that you wrote down for Time Capsule 1
Click the Internet icon, then click the Internet Connection tab
Make sure that the settings look like this:
Connect Using = Ethernet
Connection Sharing = Off (Bridge Mode)
Click Update and allow 25-30 seconds for Time Capsule 2 to restart to a green light
Very important......perform a power cycle of the entire network as follows:
Power off every device in any order that you wish
Wait a minute
Power up the modem and let it run for minute by itself
Power up Time Capsule 1 the same way
Power up Time Capsule 2 the same way
Continue starting devices one at a time the same way until the entire network is back up

Dropping Gigabit Ethernet connection

Hello,
I found out a strange issue on my mac mini 2011 with Gigabit Ethernet port and what I see that it is works on automatic mode, in 100 mbit speed, but today I bought cisko 1 gbit switch and I still see in network utility 100 mbit. If I force the 1 gbit speed in seeting I will get error message like cable was unplugged.
Don't tell me that I have broken logic board. My varanty finished 2 months ago.
Thank you.

OK ****! - was I wrong...
After the above entry I packed up my MacBook, headed out to the Mac store and dropped it for repair; they had it overnight. "The Genius" called me to pick it up the next day. The answer:
There's nothing wrong with your MacBook. They copied files back and fourth between my MacBook and many other hosts on their network; it performed as expected.
I gave him a short history of the problem, and he said, "OOOOOooohhh, it's the Belkin." I brought my baby home, did a little research, found that others had a similar problem and found an acceptable fix. I ordered the new switches, a 5-port for my desk and an 8-port for the servers in the back room; incidentally, these items were inexpensive.
I swapped out the Belkin F4G0500 for the TrendNet TEG-S50g and everything started popping:
The MacBook received (and retained) a DHCP lease
Files copied between the Mac and other hosts at gigabit speeds
I should say the rest of my gear, 3 Linux Servers, a Linux Desktop/Laptop, and printer all made use of the Belkin at gigabit speeds (100MB file between Host A <--> Host B in 2 seconds), it was only the Mac that had trouble with the Belkins.
I split this evenly between Belkin and Apple as a responsibility to fix for we the buyers. It's 2012, we should have layer 3 (switching) sorted out by now. This was minor but pricey pain in the ***.
Troubleshooting Techniques:
Create Files of a Specific Size
You can use the "dd" (Unix) program to create files of a specific size. To test gigabit speeds, specific file sizes take the guessing out of the equation.
Open the Terminal (Utilities directory)
To create test files, enter both of the following lines (line one, then line two, giving each time to finish):
dd if=/dev/zero of=~/Desktop/output_100MB.dat bs=1M count=100   # Creates a 100MB file
dd if=/dev/zero of=~/Desktop/output_1GB.dat   bs=1M count=1000 # Creates a 1GB   file
The files created in Step 3 will now be on your desktop ready for transfer/testing.
Quit the Terminal.
File Transfer Calculator
This calculator will give you an approximation of what transfer times should be; at least it's close enough for me. There will be a little flux due to various (network) conditions, within 2-3 seconds it seems, but generally these estimations should hold.
For my problem, I wanted to test a 100MB & 1GB file transfer between 2 computers (both with Gigabit Network Cards) on the same switch.
EG: for the 2 files, I fill in the calculator:
100MB file: Size: 100; Size Lable: MB; Speed Lable: -none ; Select Speed by interface: Wired Lan Gigabit Ethernet --> click Calculate = estimated 2 seconds.
1GB file: Size: 1; Size Lable: GB; Speed Lable: -none ; Select Speed by interface: Wired Lan Gigabit Ethernet --> click Calculate = estimated 9 seconds.
Verify Gigabit Speeds on the Switch
The Trendnet ports will light up GREEN for each port that is functioning at gigabit (1000 Mbit/s) speeds; ports that are only running at Fast Ethernet speeds (100 Mbit/s) will light up AMBER. Transfers must occur between any 2 computers lit green on the switch.
When I copy the files to another (host) computer I see transfer times for:
The 100MB file is on the money: 100MB   50.0MB/s 00:02 seconds.
The 1GB file takes a little longer: 1000MB 47.6MB/s 00:21
Here we see approximately 50.0MB/s transfer times for both. The File Transfer Calc estimate was off by 12 seconds but I did notice that the transfer degraded slightly (in speed) the longer it persisted; even though that's true, the MB/s is similar.
If you have a similar setup as me (1 switch under your desk, and 1 in the server room), repeat the transfers to (hosts) computers in the back room with a green light on the switch. The transfers should be similar if not the same.
It's not perfect but it's a week later and I'm almost $200 down; it's close enough for jazz and better than what I had before. I'm tired of screwing with it.
Cheers all,
TT

Aggregation 4 gigabit ethernet low speed

Hello
I've got a Synology DiskStation DS3612xs (Ultra-high performance of 1000+ MB/sec throughput and 100,000+ IOPS)
connected to my MAC PRO with 4 gigabit Ethernet connection with Link Aggregation,
and I only got 233.9Mo/s
the same performance with dual gigabit link aggregation.
What am I doing wrong to get the same speed result with 2 link aggregation than with 4 link aggregation ??
is this a apple bug ?

no the 4 link aggregat by apple is not fast enough.
if I have to different computer connected to my DiskStation via 2aggregat ethernet
each computer got 233.9Mo/s speed.
but when I connect only one computer via 4aggregat ethernet : I got only 233.9Mo/s speed
BUT I should have the +/- 466 Mo/s speed as I got with the 2 different computers insn't ???
Please help.
Thanks anyway

Can you use Airport for internet and Gigabit Ethernet for file sharing?

i would like to complicate my network setup by using my Airport connection to the internet for internet access and then use the Gigabit Ethernet connection between my G5 tower and the MacBook Pro for file sharing, Compressor's distributed rendering, and possibly iTunes music/video sharing for Front Row.
is this possible? could i just run a cat 6 cable between the two and network them together? or do i need to get a Gigabit Switch?
i suppose i could just try running the cable between them and see what happens. i don't think these new machines require cross-over cables since the ethernet ports auto-detect that now, but is a cat 5e or cat 6 cable required for Gigabit speed?
thanks,
scott

Yes it would work. The Ethernet network would be used for local file transfers and the Airport for internet. However you will need to make sure Ethernet is at the top of the list of network ports in the Network Preferences.

Is gigabit ethernet compatible with standard ethernet

I want to buy the new (5th generation) Airport Extreme, but because it only has Gigabit ethernet ports, I'm wondering whether I'll be able to connect my cable internet modem (Time-Warner), which uses standard ethernet.
Thanks for you help!

I'm wondering whether I'll be able to connect my cable internet modem (Time-Warner), which uses standard ethernet.
Yes, you will. The ports on the AirPort are compatible with Ethernet, Fast Ethernet, and Gigabit Ethernet connections.

Thunderbolt Gigabit ethernet adapter is recognized - but no internet connection

Hello.
I just got a new macbook air. I need to connect it to the internet via ethernet cable - thus i purchased the Thunderbolt gigabit ethernet adapter, plugged it in - and nothing happened.
The cable is being recognized, in the networks section it shows the IP-address etc. and the little dot next to "ethernet thunderbolt" is green. but when I open safari, there is no internet connection.
Why is this? I have updated all available software. I also tried downloading the Thunderbolt Firmware Update (1.2.1) but I'm told it is not supported (i.e. it isn't installed).
Who can help me? I'm quite puzzled and don't seem to be able to find this same problem anywhere on the net.
Thanks for your help
enel

Is that quite lousy and am I a fool? ;-) I have turned it off. It didn't do the trick, I had already tried that numerous times.
BUT this time I also switched off the DSLmodem (an idea I hadn't had up until now, strangely enough - I had it only now while actually counting to 15) and then I ran the assistant again and the network was then finally being recognized for the first time.
Then I had to once more turn the router off and finally all the little status buttons turned green.
Yeah!
Thanks a lot for your help and your readiness to help! I really appreciate it.

Ethernet Intel(R) 82579V Gigabit Network Connection prblem

Hello!
My laptop (HP Probook 6570B, with Windows 8.1 64 bit) doesn't recognise the ethernet driver. The driver is showing a code 10 error ('this device cannot start').
I tried to uninstall the driver and tryed the hp latest network driver as well as the latest original driver from Intels website.
PCI\VEN_8086&DEV_1503&SUBSYS_17AB103C&REV_04
PCI\VEN_8086&DEV_1503&SUBSYS_17AB103C
PCI\VEN_8086&DEV_1503&CC_020000
PCI\VEN_8086&DEV_1503&CC_0200

Hi:
Try manually installing the driver as follows.
First, download and install this free file utility.
http://www.7-zip.org/
Then download and save the W8.1 Ethernet driver file from Intel.
http://downloadcenter.intel.com/download/23071/Network-Adapter-Driver-for-Windows-8-1-
Now right click on the Intel driver file and select 7-Zip from the menu.
Have 7-zip Extract to, and I let it extract the file to the name of the folder (PROWinx64).
Then go to the device manager and click on the problem ethernet controller.
Click on the driver tab. Click on Update Driver. Select the Browse my computer for driver software option, and then at the bottom of that window, select the Let me pick from a list of device drivers on my computer.
Click on Have Disk and browse to: PROWinx64\PRO1000\Winx64\NDIS63\e1c63x64, and select the Intel(R) 82579V Gigabit Network Connection from the list and see if the driver installs that way.

Gigabit Ethernet AEBS just connects 100Mbit in Leopard

Hi,
I have an AEBS Gigabit version connected via Ethernet to my Macbook. Since I upgraded to Leopard I just get an 100MBit connection. When I force my Macbook to connect at 1000 MBit, the Ethernet-connection won't work.
Someone a solution or similar problems,
Thx

Since the AEBS is a stand alone device and operates the same regardless of the OS of it's clients, this isn't really an AEBS issue.
This would seem to be an issue with Leopard and the MacBook.
Have you tried making a Gigabit connection to any other device with your MacBook?

Slow internet connection with gigabit ethernet?

I have a 1Gbps (1000Mbps) internet connection from my ISP, using the internet speed testing service provided by local authorities, my internet download speed is shown to be at least 250Mbps (close to the max limit of the test) when my iMac directly connected to my wall ethernet socket.
However, when Mac is connected to the internet through my 2012 Time Capsule (all ethernet and time machine disabled), my internet download speed is slowed to 96-98Mbps.
I understand that all ethernet ports on the 2012 spec Time Capsule is gigabit ethernet, and I have checked my connection using the network utilities, which confirms that my linkspeed is 1Gbps. The hardware tab on my Network preferences also shows that my ethernet is set to 1--base T, full-duplex.
So where did the 60% speed decrease come from?   Is this ~96-98Mbps speed limit a hardware limitation? Or is my time capsule set up incorrectly?
I understand that similar questions might have been posted in the forum before, but I haven't b thread with the exact issue I described above.   Any help would be appreciated.

Many thanks for your incredibly detailed reply. All the information in your solution is correct, and while it did not directly solve my problem, it would have taken my a lot longer to figure out the issue without the information you provided.
I didn't realize we're missing so many functions in airport utility 6.0.
Anyways, upon reading your advice, I installed Airport utility 5.6 on mountain lion and checked the link speed settings.    Apparently it was automatically set to 100Mbps when connected to my cable modem.
Strangely, if I manually change the link speed to 1000Mbps full duplex, Time Capsule would report an "ethernet unplugged" error along with the consequential "internet connections" and "no DNS servers" error.   Since my ISP has been supporting consumer 1Gbps internet for a few years now, and since I am able to get an over-100Mbps actual link speed with directly connection to my cable modem, I am certain that my cable modem connection supports 1000Mbps local connections.

You're also correct in that Time Capsule does not have a settings for "half duplex" for 1000Mbps link speed. But hooking my my mac directly with my cable modem, Mac network preference pane reports that the 1000Mbps connection between my mac and cable modem is full duplex, so my ISP does allow full duplex 1000Mbps connection.
After NUMEROUS tests, I discovered the problem is down to a FAULTY ETHERNET CABLE, which I did not use for my Mac -> cable modem direct connection. This was why I was able to get gigabit ethernet speed with a direct connection but not through time capsule!
I replaced the faulty cable with a new cat-6 ethernet cable and voila! problem solved!
So here're the test results (using an more up-to-date speed test) before and after I replaced the faulty lan cable:-
(while I'm at it, I've also thrown in some additional results demoing the wired and wireless throughput of the 4th gen Time Capsule)
Faulty cable through Time Capsule:-
New ethernet cable direct connection:-
Wired connection through Time Capsule:-
Wireless Connection (wireless-n 5GHz three streem 450Mbps transmit rate) through Time Capsule:-
I'm a bit surprised that a damaged cable resulted in a lower link speed rather than no connection at all.
Also, while the throughput of Time Capsule can't really match the link speed of the direct connection, I'd say it's not shabby at all.
Thanks again LaPastenague for your solutions.

Why would i connect a external hardrive to the airport extreme and what is the difference between LAN and WAN gigabit ethernet?

Hey just wanted to know what is the reason i would connect my external hardrive to the extreme and what is the difference between LAN and WAN ehternet. I know one is local and other is wide but can someone explain in simpler terms.

Connecting a hard drive to the Airport Extreme makes it available to be shared across all the computers on your network.
WAN (Wide Area Network) is your connection to the internet
LAN (Local Area Network) is your internal (or local) ethernet connections (computers, printers, etc...)

G5 Can't See Gigabit Ethernet Card

Some months back, I installed a gigabit ethernet card into my G5. It worked fine for a few months, then stopped working with a message: The cable for PCI Ethernet Slot 3, Port 2 is not plugged in. I wasn't working on the project that required that connection, so I just let it go. Now I need to connect to a different gigabit switch. I installed a new D-Link card into the same slot as before - same result. I moved the D-Link card to a different slot - and got the same error - still referring to Slot 3. Just for kicks, I installed the old card back into slot 2 (the one above the video card). Same error - and no mention of finding two cards or of anything in the other slots. It seems as if somehow all of the PCI slots are being ignored.
Running the System Profiler, I get a "No Information Found" for PCI Cards. None of the lights on either ethernet card come on. Any ideas? Everything else on the machine seems to be working correctly - the built-in ethernet is fine. There are a lot of drives connected to the system (4 on the FireWire 800, 1 on FW 400, 4 on USB). Is there some way to force a re-scan of the PCI bus? or turn it on?
Thanks!!
G5 2 X 2 GHz Mac OS X (10.4.8)

Thomas -
Yes - I tried swapping slots. A gigabit card worked fine in slot 3 for several months. It stopped working - I figured it was the card that was th eproblem. I have since replaced the card, and then moved the new one to a different slot. The Network control panel still reports a card in slot 3, even though there is nothing in slot 3. The new card is in slot 4 (and just for kicks the old card is in slot 2). Neither of these is recognized by the the System Profiler or the network control panel.

What's the maximum LAN speed with the Thunderbolt to Gigabit Ethernet Adapter on my MacBook Pro?

While I was at Yodobashi Camera yesterday, I got a Thunderbolt to Gigabit ethernet adapter for my MacBook Pro. I figure, since I'm paying for the high speed fiber optic (Sony Nuro), why limit my self to wi-fi speeds at home?
Before connecting the adapter, via wi-fi it the speed was 143.8 Mbps down and 181.5 Mbps up.
After connecting the adapter and making a direct LAN connection to the router, the speed is 783.2 Mbps down and 940.1 Mbps up.
I'm certainly happy with the speed, but since Sony Nuro is supposed to be 2 Gbps down and 1 Gbps up I was wondering what the maximum possible is with this computer and adapter. Before asking the provider I was curious what the maximum specs where.
The ether cable is a 3 m category 6.
Thanks,
doug

It's not really your computer that is getting the 2Gbps download - it is the router/ modem.
If you hooked better/ different hardware up you could probably push those speeds around your network too. The trouble is that most residential hardware is gigabit ethernet not fibre. Fibre cards & cable are expensive in comparison.
The existing hardware may allow you to 'bond or aggregate' multiple ethernet connections into one link to get more speed over ethernet. Obviously this requires more complex routers, switches & a network admin to set it up
Those speeds sound nice, this bottleneck will mean that other devices on you network can't choke up the whole connection & make other users sad.
