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?

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.

Airport extreme (gigabit ethernet) b/g not working

I have an airport extreme (gigabit ethernet) that I use as my base in an extended network. I Have always had it in Wireless N mode with b/g compatability. the other day my speeds went from being super fast and happy to less than 1mbps. I went and plugged directly in to the airport via ethernet and got blazing fast speeds again.. I switched my radio mode to n only and wireless speeds were fast again.. switched back to b/g compatible and they are in the toilet.. is it possible for the b/g compatible antenna to just crap out? if so this is very disoncerting as I have several wireless devices in my home that operate on b/g and don't want them to be left out in the cold.
Any input is greatly appreciated.

what I did with the b/g testing was I changed the name of the base station to another name so none of the b/g devices that were connecting to it could.. and so it was only the laptop I was using to run the tests.. and still the speeds were terrible.. of course then when I changed it to "n" only mode they were fast again. so I know that my laptop was the only client connected wirelessly or otherwise to the base station when running both tests.
I am extending the network with an airport extreme base station dual band. The solution I have in place currently is to basically swap them. I Have the Dual band running as the main base station in N mode with b/g compatability, and I have the Gigabit ethernet AEBS running as the extender... so far my speeds haven't suffered at all and hopefully it will hold that way. but I still can't understand why the AEBSn would suddenly just stop providing any kind of speed when running as the base in b/g compatibility mode.

Thunderbolt to Gigabit Ethernet Adapter problem

Hi all
I have replaced my black 2008 mabcook with the new 13" retina MBP.
I bought the Thunderbolt Gigabit Ethernet Adapter to connect to my office network.
A access without any problem to Intranet content and file server, but when I use Internet, where I must connect via a proxy, I constantly get error messages like "the server unexpectably stopped the connection" or a Proxy error "The number of HTTP requests per minute exceeds the limit".
I got my black macbook back to my office to test and I have no problems with it.
At home, I also have no issue using the thunderbolt adapter.
Any suggestions?

It is always best to speak to the IT and see what they think.
I was just guessing in my post - they should give you the full answer even if they cannot alter the settings for you.
From your side you can try to work out what is generating big amount of http requests (applications you run on your MBPr while in the office?).
Also USB to Eth dongle may slow you down :-)

but I understand that buying something worse than you already have is not really an acceptable solution.

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.

Leopard Defaults to Wireless, even when Gigabit ethernet is plugged in...

This is a bit of frustration for me, but after installing 10.5.5, it seems as though leopard defaults to use the wireless connection instead of the "fastest available" connection.
When I plug in ethernet, i stay connected via wireless, even though I have an IP over ethernet. when I try to access ethernet-only local services, I am denied unless I turn off the wireless connection.
This did not happen in previous updates of Leopard. I found that without turning the wireless off I could access the local services just by plugging in the ethernet.
Any ideas?

You can reset the Service Order on the gear drop down in System prefs > Network which might help.
Sorry no idea if or when it changed, I've always just turned Airport off on the menu bar when using my USB mobile modem.

As a Verizon FIOS client, can we just use Ethernet cable to connect to time capsule, or do we need their router to connect to the time capsule?

As a Verizon FIOS client, can we just use Ethernet cable to connect to time capsule or do we need the Verizon router to connect to time capsule?

The Time Capsule is indeed a wireless router with simultaneous dual band capability...and a hard drive for backup purposes. You can use that to your advantage if you configure the Time Capsule as I suggested in Bridge Mode.
The Time Capsule will provide a 802.11n 5 GHz band and a 802.11n/g/b compatible 2.4 GHz band to allow virtually any device to connect to the network.
I suppose that you could also use the "g" wireless network provided by the Verizon router as a "guest" network or something similar if you really do need another wireless network.
It might be possible to configure the Time Capsule as the main router on the network....that's a question for Verizon. But even if you might be able to do this, I'm sure it is not supported by Verizon, so you would be on your own in the event of any Internet connection difficulties on your service.
And, since the Time Capsule does not have a built in modem....you would still need to add a separate modem to the installation anyway.
That's why my suggestion is to use the Verizon device as the "modem" and let the Time Capsule provide the dual band wireless network and of course, handle the Time Machine backups.

Gigabit vs. Fast Ethernet (AEBS 802.11n)

Hi,
I have an AEBS 802.11n that I bought back in September 2007. It currently has the 7.2.1 Gigabit Ethernet firmware on it. I want to revert back to older firmware (because of some file transfer problems I have been having) and I see my choices are 7.2 Gigabit Ethernet, 7.1.1 Fast Ethernet, 7.1 Fast Ethernet. I am not sure which one to choose. Is it OK to put Fast Ethernet firmware on the AEBS even if it currently has Gigabit Ethernet firmware? What is the difference between those?
Thanks.

You should choose "7.2 Gigabit Ethernet".
The older versions are for the Airport Extreme N Base Station model previous to the one you own, which had only 100Mbps ethernet ports.

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.

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.

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

ATI/Radeon 9800 Pro 128 AGP 4x/2x in Gigabit Ethernet dual 450 PMac G4

Hi,
This is my first time posting to these discussion group... I've been going through related threads and have not found an answer to my problem...
I have a Gigabit Ethernet dual 450 G4. Awhile ago I upgraded the processor to a Sonnet 1.8ghz so I could run Leopard.
I just bough the ATI/Radeon 9800 Pro 128 AGP 4x/2x video card. I researched around and that seemed to be a card that would work in my machine. I even read a review on Amazon where someone had also upgraded to the 1.8 processor used this card with no issues.
I do have an older monitor - Apple Studio Display CRT with the ADC connector. So I also bought the Apple DVI to ADC adapter kit.
I installed the card and do not get any picture at all - I believe I have installed everything correctly. I'm pretty sure I can hear the fan on the video card in the machine. The monitor is getting power from the adapter since the button lights up when I press it - but it does not stay lit -- the monitor never turns on. Using my old graphics card the monitor makes a little "beep" when it turns on.
In reading the other topics I am wondering if it might be a power issue? According to Other World Computing's profile my machine has a max of 220 watts. Although they suggest this video card as one the will work in my machine.
I have disabled the hard drive that came with the machine (too small) and am using two Maxtor hard drives that I added - one ATA (120gb) and one SATA (500gb) that is connected to an SATA pci card. I also have two additional pci cards with usb 2.0/firewire ports.
In looking at the topics here I came across the link about taping the 3 and 11 pins on the video card. Even though the card I have is 4x/2x not 8x I thought I'd give it a shot. That did not work either.
Any help you can give would be greatly appreciated.

I don't wish to sound redundant here, but I've been reviewing the vendor's page:
It's OK- I don't mind beating this dead horse....
The maker says such to protect themselves from possible claims that may arise due to over loaded systems and power problems when their card is installed in said system.
Of course, 300w would be nice, but they didn't even specify the PSU rating a couple years ago. The Sawtooth, with it's 237w PSU, used to be listed as a compatible machine for the 9800...... They just didn't consider how far a Sawtooth might be modded.
Within reason, the early G4's (Sawtooths) are capable of using the Radeon 9800 Pro. The GE has the same 338w PSU as the DA (they are interchangeable), so there is plenty of power for the 9800.
One thing to remember, the requirements of the ADC port of the AGP slot are removed by using a non ADC card. This really changes the calculations of the power available.
It's kinda' a long post, but, if you care to get ALL the details, check the following:
http://discussions.apple.com/thread.jspa?messageID=7065653&#7065653
I think you'll be satisfied with the explanation.......
Which leaves your second, and very appropriate, point.
The main enemy of all, though, isn't power. Heat is the biggest concern.
Reducing heat/increasing cooling by using a third party fan on the 9800 is highly recommended. The 9800 is a hot card, and the stock fan is prone to early failure.
Adding additional cooling to remove the extra heat produced by the 9800, by using an exausting PCI fan, will also help the PSU provide adequate voltage to the system, by reducing the amount of hot air moving out of the PSU.
Super heated air moving through the PSU reduces the cooling ability of the PSU. A hot PSU doesn't produce reliable power.
So, add the 9800, add some cooling, and enjoy!

Supplementing Airport Extreme 802.11n network with Gigabit Ethernet wired

Right now, I have an AEBS (Gigabit Ethernet) as my Internet router and network host, with an Airport Express elsewhere in the house to extend range for wireless devices. I'm steadily gaining A/V items with Internet or networking connectivity. AEBS and the A/V equipment are in different rooms. I am concerned that setting those devices up for wireless will cause needless complexity with inferior performance to Ethernet.
Here is what I think I should do:
1. Get wall panels installed by both the AEBS and A/V equipment wired for Ethernet;
2. Set up a Gigabit Ethernet switch in the basement, into which all these Ethernet outlets would run; and
3. Connect both the AEBS and the various A/V devices into the wall (and thereby through to the Ethernet switch) through their Ethernet ports. The goal is to have all of the devices on the same AEBS-hosted network to share data and have access to the AEBS Internet connection.
Any reason this should not work? Would the AEBS and the Ethernet switch need to be in the same room for any reason? I'd just like to make sure all of my ports are running in the right direction. In particular, I'd like to know if I am making this more complicated than it needs to be.
Thanks for your comments.

What you are planning should work without any problems.

Airport Extreme has been updated with Gigabit ethernet - so soon!!!

I just bought a brand new state of the art AE two months ago and then Apple just updates it with Gigabit ethernet so soon after?! I feel cheated in every way!

If you want to measure speeds - actually the Kona disk utility is a pretty decent free tool you can use - it's typically used for testing disk for media encoding/decoding, but it's got a nice graph you can look at to see what the drive performance looks like over time.
To make sure you're running as fast as possible - try connecting the disk directly (assuming you're using a USB-2 bus and a USB-2 hub) and transferring files, then compare that to what you're getting across the AEBS .. also try eliminating the hub - I've found many hubs that are "rated" as USB-2, but don't run very close to rate. With the older AEBS you should get 100Mbps wired and 130Mbps with 802.11n .. best case is you're running about 25% of what the USB-2 bus is capable of.
oh, and you can verify your connection speed with Network Utilities -- look at the Info tab for each of your interfaces to see your negotiated rates
