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:
Supported ports: [ TP ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Half 1000baseT/Full
Supports auto-negotiation: Yes
Advertised link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Half 1000baseT/Full
Advertised auto-negotiation: Yes
Speed: 100Mb/s
Duplex: Full
Port: Twisted Pair
PHYAD: 1
Transceiver: internal
Auto-negotiation: on
Supports Wake-on: g
Wake-on: d
Current message level: 0x000000ff (255)
Link detected: yes
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.

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.

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.

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"

Other topic is removed
>>Please read and comply with the Forum Rules.<<
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.

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.

No, it does not work on a livecd(x86_64), someone has reported it works on a ubuntu distribution(possibly a 32-bit version), but I did not check it as the laptop does not have a cd driver.
Just now I tried it by using a 32-bit usb-image livecd, still does not work.

Gigabit ethernet + TC doesn't mean gigabit transfer rates to the TC drive..

Alright.... I've spent a ton of time trying to figure this out (probably more than I should have) and I thought I'd post my findings so that either a) I'll save someone else time out there or b) someone can tell me I'm a complete moron
So I had an airport extreme. I replaced it with a Time Capsule. I have a Windows (boooo) PC connecting directly to my TC using a gigabit ethernet card (which I bought specifically connect it to the TC) so (I thought) I could enjoy gigabit transfer speeds to the internal hard drive from the wired PC. I had some fun plans of shoving my itunes directory on the TC and letting appletv sync (yes through my pc) and keeping lots of videos there, etc. Who cares - it'd be at gigabit speeds! But, in reality, things didn't quite work that way (though my itunes directory does still live on my TC...for now).
Well, I had a semi-unique situation to do some pretty massive testing because I have 2 gigabit network cards, 1 100mb network card, and a wireless-n network card and two internal hard drives - both very fast. I also tried Cat 5, Cat 5e, and a Cat 6 cable.
And here's what I (think I) figured out:
The hard drive in TC can not achieve gigabit transfer speeds. Your transfer rates will be limited by the IO to the hard drive. In fact, it can't even come close.
Using my "fastest" setup - so Cat 6, fastest internal drive, gigabit ethernet, and transferring a file exactly 1 gig in size I was able to have a sustained transfer rate of 140 megabit per second - that's 17.4 MB/s for folks not wanting to do the math (that's reading FROM the TC. Writing TO the TC dropped the speed down to 106 megabit/second or 13.35 MB/s). Going to a 5e cable knocked that down to 130 megabit a second. Putting in a Cat 5 cable knocked me down to 110 megabit a second. Switching between my two gigabit network cards did nothing. Switching my cards between two computers did nothing.
Now, just changing the above setup to use my 100Mb network card resulted in these results: 67 megabit read (8.4MB/s) and 65 megabit write (8MB/s)...
And using wireless N, I got about 10MB/s up and down.
And just as a final test, connecting my two computers together using the 2 gigabit network cards through the TC, I was able to achieve standard gigabit speeds.
SO what does this all mean?
I think the IO to the hard drive in the TC can only read at about 140 megabit/s and write at about 110 megabit/s. I'm not sure if it's the HD itself or how it's connecting to the TC - but that's why I'm not aware of anyone getting faster transfer rates to the drive in the TC (maybe you guys are?). The gigabit ports themselves are fine - and if you're doing anything from one gigabit port to another gigabit port you'll be fine.
So stop beating yourself up trying to find some elusive XP specific issue with gigabit transfer rates (though vista had a problem - shocker), or that you must have a defective gigabit card (which is why I have two cards now instead of one :)), or that your cable must be bad ("maybe my cat 5e isn't good enough?")... it's just this drive ... or how the drive is connecting to the network - can't handle the gigabit speeds.
Unless someone else out there has another explanation? Do these speeds mesh with what you're seeing in "optimal" situations? Or maybe there's just a throttle switch for goobers like me using Windows instead of MacOS!

Hi,
the interfaces available today which connect your drives integrated electronics to your computer can handle that speeds. but the drive itself is limited by the mechanical things going on in there
You can get such transfer speeds if the data you request is in the cache of the drives internal electronics for example. Some drives have 8 MB of cache memory. So if you request to read or write less than 8 mb and (in the read case) you are lucky enough to have those few megabytes cached then you may get that performance

How big of a hardrive can i use in my gigabit ethernet g4 dual 500.

Hi there.
I wanted to now how big of a hard drive can i use in my gigabit ethernet g4 powerpc with a dual 500 processor . at the present time i have one 80 and one 20 gig drive in there now.
So my answer is how big of a drive can i use before i have problems with seting it up. Like i want to use a 500 gig drive in my computer and my old 80 gig too. i want to buy a apple tv and store my dvds on the big 500 hardrive so i have alot of room for the vidio files, for apple t.v . If i can use one as big as one terabite you now the real big one that would be fine. The more room i have the better for me. I will be able to watch the movies i downloaded from the internet and i wont have to burn them at all.
This is of corse if apple tv will handle it.

Hi-
If you need that much storage, and you'll have to buy a controller anyhow, get a SATA controller card, and put one or two 500gb SATA drives in. The enterprise class of SATA drives are made especially for multi media storage, have excellent seek times and fast data transfer rates. A "bargain" on a package can be had at OWC:
http://eshop.macsales.com/item/Other%20World%20Computing/SATAM500GPCI/
or
http://eshop.macsales.com/item/Other%20World%20Computing/SATAM10TBPCI/
The MaxLine Pro drives have great characteristics, and are reviewed favorably.
I have an OWC SATA card, and the card works perfectly, and is cheaper than other makers cards of equivalent specs.

Mac Mini Server Link aggregation - Thunderbolt or USB 3 gigabit ethernet adaptors

I am setting up a late 2012 Mac Mini as a file server with Server 2.2. It has a Promise Pegasus R4 RAID and LaCie 4TB drives daisy chained via the Thunderbolt connection. 4 users on MacPro's will connect to the server to access these hard drives via gigabit ethernet.
I imagine the gigabit ethernet will be the bottleneck, so I'm now looking at link aggregation. Not a problem on the MacPro's but the Mac Mini will require an adaptor to get a second gigabit port. From reading this forum I understand the Apple Thunderbolt to Gigabit adaptor will work, but I'm concerned that it will need to be fitted 3rd in line after the R4 and LaCie drives. The 10Gbps bandwidth Thunderbolt has, may cause another bottleneck with all three working off the same port?
An option would be to use one of the USB 3 ports with this adaptor http://www.ebuyer.com/412005-startec...edium=products
I believe it work with OSX, but I have no speed information or if OSX link aggregation will work using it.
Any thoughts on the above would be appreciated and recommendations on a suitable Network Switch with LACP support welcome.

At present Mountain Lion Server cannot use a LACP bond, in my experience only of course. http://www.small-tree.com/kb_results.asp?ID=59 describes LACP/Bonds do not show up in Server Admin GUI on Mountain Lion
anyone know how to do it? or the location and the name of the plist file to configure the network interface in ML server?

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.)

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!

Thunderbolt to Gigabit ethernet does not work anymore.

I had purchased a Thunderbolt to Gigabit ethernet a few months back and has been working fine. Recently in my Network Preference it is not recognized anymore. I removed it hoping it would pickup and nothing. I switched ports and nothing. I tried my adapter on another MacBook Pro and it worked fine. I tried a new TB to Gigabit ethernet adapter and still did not work. Thinking something maybe wrong with my ports I tried a Thunderbolt to DVI adapter and works fine.

This is a late reply, but I had this same question and found the answer here:

To me, it was a network reconfiguration problem, I simply went to System Preferences --> Network --> Assist Me, had it reconfigure my connections, and now my Thunderbolt-to-Gigabit-Ethernet adaptor works fine.

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

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.

Thunderbolt to Gigabit Ethernet reconnect slow after sleep

Hello, guys.
I couldn't get the management of where I work to give me a working WiFi (they offered an insecure, unprotected WiFi... madness), so I had to opt for Gigabit Ethernet. I bought the Apple Thunderbolt to Gigabit Ethernet adapter for my 2012 rMBP on OSX 10.8.5. All software is updated via the App Store.
The adapter is working fine for the most part, but there is something that I find bothering: when the computer wakes up the adapter takes something like 30 seconds to achieve a working Internet connection, which is a pain. It's an issue I've never experienced in any other computer or setup, either wired or wireless, and it makes little sense (if WiFi is able to reconnect instantaneously, why can't this adapter?)
I don't know if it's a side issue of the adapter having to boot, the need for refreshing the IP address through DHCP or whatever, but it's something that I'd rather find a solution to. Of course, it feels like a first world problem (it certainly ain't critical) but if there is a known workarround I'd like to know.
Thanks.

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.
