Problem speeding up to gigabit ethernet

Hello,
Hopefully someone here will be kind enough to help me out with this one...
Im trying to set up a gigabit ethernet network with my PowerBook G4 12" 1.5 GHz, a gigabit switch, and an iBook G4 1.2 GHz. The problem is that when I connect everything together I only get 100baseTX speeds max. On both the iBook and PB if I go into Network Preferences and configure ethernet speed Manually (Advanced) it only shows autoselect, 10baseT, and 100baseTX. No 1000base...
I have tried multiple cat 5e and 6 cables, all known good.
I have also tried the setup without the gigabit switch (ethernet cable between the two computers) and still get the same result.
Oh and both systems are running 10.4.7
Any help with this would be very much appreciated.
Thanks in advance!
PowerBook G4 1.5 GHz, a gigabit switch, iBook G4 1.2 GHz Mac OS X (10.4.7)

No problemo. At least now you won't be tearing your hair out trying to figure out why you can't get the data moving any faster. Happy 4th.

MOVED: problem with killer e2200 Gigabit Ethernet Controller

WiFi does not use Killer network, and even though your device is connected through ethernet, it is still wireless. Might be that Killer NIC and your device (and its driver) cross over each other and cause random issues. Try standard Ethernet->Modem connection (straight 1m connection) and see if you get internet drops then too.

Macbook Pro does not see Fast Ethernet but works fine with Gigabit Ethernet

Hi to everybody,
It is some time I have a problem connecting my unibody Macbook Pro (late 2008) to the ethernet cables in my office. There are 16 wall jacks in the lab, of which 13 are Fast Ethernet (100 Mbit/s) and 3 are Gigabit Ethernet. No matter what I do, if I connect to the 100 Mbit/s jacks, my Macbook does not see the connection and keeps saying "Cable unplugged". If I switch to a Gigabit jack, then a connection is quickly established.
I have spent one whole afternoon debugging. Here is what I did:
My computer dual boots Mac OS X and Linux. No matter which operating system I use, the problem is the same.
Using different Cat.5 cables does not change the situation (I tried three of them.)
All the 13 Fast Ethernet jacks do not work.
All the 3 Gigabit jacks work smoothly.
What puzzles me is that my computer happly uses the newest technology (Gigabit ethernet) but has problems with the oldest one. Has somebody else experienced the same problem?

After a lot of struggle, I discovered that other people had this very issue as well. It seems that the cause is a faulty Realtek chip used in the ethernet cards of some MacBooks and other brands. There is apparently no way to fix this: I solved my problems by buying a Gigabit Ethernet switch which I connected to the Fast Ethernet wall jack. (Another option might be to use a Ethernet-to-USB adapter - but I did not try this as I have no adapter of this kind.)

How do I maximize LAN speeds using Gigabit Ethernet, jumbo frames?

I move a lot of large files (RAW photos, music and video) around my internal network, and I'm trying to squeeze out the fastest transfer speeds possible. My question has to do both with decisions about hardware and what settings to use once it's all hooked up.
This is what I have so far:
-- imac 3.06GHz, macbook pro 2.53GHz
-- Cisco gigabit smart switch capable of jumbo frames
-- Buffalo Terastation Duo NAS (network attached storage), also capable of Gbit and jumbo frames
-- All wired up with either cat6 or cat53e.
-- The sizes of the files I'm moving would include large #s of files at either 15MB (photos), 7MB (music), 1-2GB (video) and 650MB (also video).
-- jumbo frames have been enabled in the settings of the macs, the switch and the buffalo HD.
-- I've played with various settings of simultaneous connections (more of a help with smaller files), no real difference
-- Network utility shows the ethernet set to Gbit, with no errors or collisions.
-- have tried both ftp and the finder's drap and drop
-- also, whenever I'm doing a major move of data, I kick my family off the network, so there is no other traffic that should be interfering.
Even with all that, I'm still lucky to get transfer speeds at 15-20mbps, but more commonly at around 10. The other odd thing I've encountered while trying to up my speeds, is that I might start out a transfer at maybe 60mbps, it will maintain that for about 30-60sec and then it appears to ramp itself down, sometimes to as low as 1-5mbps. I'm starting to think my network is mocking me
I also have a dual band (2.4/5) wireless n router (not jumbo frame capable), but I'm assuming wired is going to trump wireless? (NOTE: in my tests, I have disabled wireless to force the connection through the ethernet).
Can anyone help with suggestions, and/or suggest a strong networking reference book with emphasis on mac? I'm willing to invest in additional equipment within reason.
Thanks in advance!

I'm going to pick and choose to answer just a few of the items you have listed. Hopefully others will address other items.
• This setup was getting me speeds as high as 10-15MB/sec, and as low as 5-6MB/sec when I was transferring video files around 1-2 GB in size
I would think a single large file would get the best sustained transfer rates, as you have less create new file overhead on the destination device. It is disturbing that the large files transfer at a slower rate.
• Would a RAID0 config get me faster write speeds than RAID1? I have another NAS that can do other RAID configs, which is fastest as far as write times?
RAID0 (Striped) is generally faster, as the I/O is spread across 2 disks.
RAID1 is mirrored, so you can not free the buffer until the same data is on BOTH disks. The disks are NOT going to be in rotational sync, so at least one of the disks will have to wait longer for the write sectors to move under the write heads.
But RAID1 gives you redundency. RAID0 has not redundency. And you can NOT switch back and forth between the 2 without reformatting your disks, so if you choose RAID0, you do not get redundency unless you provide your own via a backup device for your NAS.
• what is the most efficient transfer protocol? ftp? smb? something else? And am I better off invoking the protocol from the terminal, or is the overhead of an app-based client negligible?
Test the different transfers using a large file (100's of MB or a GB sized file would be good as a test file).
I've had good file transfers with AFP file sharing, but not knowing anything about your NAS, I do not know if it supports AFP, and if it does, whether it is a good implementation.
If your NAS supports ssh, then I would try scp instead of ftp. scp is like using cp only it works over the network.
If your NAS support rsync, that would be even better, as it has the ability to just copy files that are either NOT on the destination or update files which have changed, but leave the matching files alone.
This would help in situations where you cannot copy everything all at once.
But no matter what you choose, you should measure your performance so you choose something that is good enough.
• If a client is fine, does anyone have a suggestion as to best one for speed? Doesn't have to be free -- I don't mind supporting good software.
Again just test what you have.
• Whats a good number to allow for simultaneous connections, given the number of files and their size?
If the bottleneck is the NAS, then adding more I/O that will force the disk heads to move away from the current file being written will just slow things down.
But try 2 connections and measure your performance. If it gets better, then maybe the NAS is not the bottleneck.
• What question am I not asking?
You should try using another system as a test destination device in the network setup to see if it gets better, worse, or the same throughput as the NAS. You need to see about changing things in your setup to isolate where the problem might be.
Also do not rule out bad ethernet cables, so switch them out as well. For example, there was a time I tried to use Gigabit ethernet, but could only get 100BaseT. I even purchased a new gigabit switch, thinking the 1st was just not up to the task. It turned out I had a cheap ethernet cable that only had 4 wires instead of 8 and was not capable of gigabit speeds. An ethernet cable that has a broken wire or connector could exhibit similar performance issues.
So change anything and everything in your setup, one item at a time and use the same test so you have a pear to pear comparision.

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.

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.

Gigabit ethernet (tg3) problem

Hi all
i have this ethernet
Ethernet controller: Broadcom Corporation NetLink BCM5789 Gigabit Ethernet PCI Express (rev 21)
using tg3 driver but link is up to a speed of 100 as ethtool shows
Settings for eth0:

I tried changing speed with ethtool but nothing happens
It is connected to a Gigabit switch wich operates perfectly (other computers on switch work in Gigabit speed)
Any ideas?

Kind of worked it out. I think that the port is 'mini display port' only and not Thnderbolt, doh. I now have a Mini Display port to VGA Adapter and a Thunderbolt to Gigabit Ethernet Adaptor which I cannot use. Since I bought them from an Apple shop with in store support I feel miffed. Thank you for your help gmalone1.

IMac i5 27" - gigabit ethernet speed slooooooow

I know there are other (older) threads about this (https://discussions.apple.com/thread/2236017?tstart=0) but I thought I'd start a new one.
I have just purchased an iMac i5 27", and find that plugging it into my Netgear GS605 gigabit ethernet switch doesnt work as expected. My older 24" iMac works as espected, just fine.
I am able to get a gigabit connection (green light on switch) and if I try to copy large files form another Mac or my Lacie 2Big Network 2 NAS it works fine. BUT, if I then try to surf the web, my download speeds are ridiculously low (should be 30MB/s, getting 0.4)??
If I manually downgrade the ethernet controller settings to 100B/T, the internet speed works just fine, but obviously local transfers are then crippled to fast ethernet speed, which on a 200GB Time Machine backlup isn't much fun!
I have had many conversations with Apple Support, and returned one of these iMac's already, to find the next one does the same thing - all very frustrating.
So is there a fix? Can the Broadcom chipset be to blame? Is it to do with Jumbo frame support (whatever that is) - the Netgear switch supports it, but not sure about the iMac, and why does the internet speed drop so dramatically, when the file transfer speed works as expected over gigabit ethernet?
Grrrrr. Really frustrating I can't have high speeds on both types of transfer.
Any help gratefully received!

Unacceptable.
btw, i've already tried creating another user, and while things are ok in the beginning, slowly but surely the same symptoms begin to appear and then become chronic.
Have you tried Safe Mode (It will take more time to startup in Safe Mode because it runs a directory check.)
PS: i am sitting here proofreading this, and i can hear the machine every 5 seconds or so, going >"chunk-chunk" - ***!!??
That actually sounds like a bad hard drive. Run Apple Hardware Test

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

What file transfer speeds are possible over Gigabit Ethernet - Hatter?

Thanks in advance for taking the time to consider this.
Our still photgraphic studio has a range of MACs all connected via a gigabit D-Link switch to a series of Buffalo NAS raids. Wiring is CAT5e, all devices have gigabit ethernet cards and the link lights on the switch suggest that all devices are connected at that speed.
We currently get file transfer rates of between 5 and 12 MB/s depending on network traffic.
We would like to upgrade our NAS to a NAS/SAN, preferably using the existing wiring (and avoid the expense of Fibrenet). 50 or 60MB/s would be great if possible.
Any ideas for a suitable archtecture and Hardware would be gratefully received. Cable lengths are a maximum of 30 metres.

I'm getting sustained speeds of 90-100 megabytes/second on a transfer across GigE from one mac to another, both working on high-capacity SATA drives.
It drops to ~65 megabytes per second if the source drive is my 2TB Firewire 800 external.
both rates are right on the real-world maximum for GigE and FW800 respectively, which is a great sign that nothing else is bottlenecking the transfer.
My experience with NAS boxes has been disappointing in the past, with transfer rates of 5-35 MB/sec - painfully slow for large files, which destroys the purpose of NAS for me, which is reasonably high-speed off-computer storage.
I'm MUCH happier, and didn't have to pay very much to set up a Mac with 4 SATA drives onboard, acting as a file server... I'm actually getting files FASTER than I am from a FW800 drive directly attached now.

Not getting full Gigabit Ethernet Speed on iMac Core Duo

I am using Airport to connect to a Linksys Wireless Access Point connected to my DSL modem. I am using ethernet to connect to a 3Com OfficeConnect 8-port Gigabit switch. I have 2x 500 GB LaCie Ethernet Disk Mini's (with Gigabit interface) connected to the switch.
The lights on the switch tell me that the drives and iMac are connected at full speed, however I can transfer a 650MB .dmg file to a firewire 400 drive in 1/4 of the time it takes to transfer the same file to one of the gigabit ethernet drives.

I have no idea what that all means, but i do know that I am not getting gigabit ethernet speed.
Can anyone help?
Thanks

If you are transferring data via wireless then you cannot approach Gigabit Ethernet speed. 802.11g has a maximum transfer speed of 54 Mbps while 802.11n is about 130 Mbps. This is much slower than a FW400 port. Your router and switch must both be Gigabit capable and your drive must be connected to Ethernet to even hope to achieve Gigabit speeds - no wireless.

KT4-Ultra FSIR Gigabit ethernet problem

Hello,
just wondering if anyone has had a problem with getting the onboard gigabit ethernet to work? I've had some problems, but I connect to a functioning 10/100 network, so that may be the problem.
thanks,
bill

Hi Gert.
Thanks for the reply. No I don't know what GIGABIT is!?
I thouth 'Broadcom NetXtreme BCM5702 Gigabit Ethernet' was the name of the network card sitting on the motherboard!?
It looks like I'm accessing internet via that network card from Linux (which I am using right now)...
So do you know what I need to do to get the integrated network card work in windows 98. It should've been 'plug n play' but it don't seems to work. This is what I've tried so far (well, at least something like this): 'Control Panel -> Network -> Adapters -> Add -> Broadcom -> Broadcom Gigabit Network... something...'.
Is this aproach totaly wrong...

Killer e2200 Gigabit Ethernet Controller (NDIS 6.30) problem

Hi everyone, i had this problem since november:i had a gaming pc(specifics below) with a Killer e2200 Gigabit Ethernet Controller (NDIS 6.30).The problem is that my pc disconnects every 30 min more or less,for a minute.I tried formatting my pc and installing windows 8.1 (before, i had win 7 home premium) but still nothing.I don't know where the problem could be, because other devices (smartphone,tablets adn also other pc) don't disconnect.
If you could help me, i'll give you other informations as much as i can.
Thanks
i'm using a TP-LINK EXTENDER 300 Mbps which is connected with ethernet cable to my PC.It's an universal WI FI range extender.
EDIT: I posted this topic into "other MSI product"

Thunderbolt to gigabit ethernet problem

On my new Macbook Air (Intel Core i7) I'm trying to connect to my office network using a Thunderbolt to gigabit ethernet adapter, but the network system preferences say that the cable is unplugged. Any suggestions for how I can go about checking what's up?
Many thanks,
Adriaanh

I had this probem also in 10.9.
I was selecting Thunderbolt 1 from the dropdown list of interfaces.
It took a while to realize that Thunderbolt Ethernet is actually the correct option, lower down in the list.
