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.

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

Macbook pro runs really slow after sleep mode

My MBP ( MacBook Pro (13-inch, medio 2012), 2,5 GHz Intel Core i5, 8 GB 1600 MHz DDR3, Intel HD Graphics 4000 1024 MB), runs very slow after sleep mode. I notice that when I wake it up, my memory usage is nearly 8 GB. After a restart it is back no a normal level, between 2 and 5 GB depending on how many programs I am running. Any ideas what causes this? My IOS is Yosemite 10.10.2
Kind regards

Hi Japib
Thanks for your reply. Here is my report:

Can the Gigabit Ethernet LAN Port be used with a Thunderbolt to Gigabit Ethernet adaptor and then to a Thunderbolt Hard Drive as a back up drive?

Can the Gigabit Ethernet LAN Port be used with a Thunderbolt to Gigabit Ethernet adaptor and then to a Thunderbolt Hard Drive as a back up drive?

If you use ethernet to connect the two AirPort Extremes together, you'll have Gigabit speeds available at all of the ethernet ports on both routers.
If you connect the second AirPort Extreme using wireless only and configure the Extreme to "extend a wireless network", then the maximum speeds that the second router can attain will be limited to the capability of the wireless connection. So, if you connect at normal "n" wireless speeds of say 130 Mbps, that will be the maximum speed available at the ethernet ports on the second AirPort Extreme.
I think you can easily see the difference between Gigabit ethernet, which is 1000 Mbps compared to "n" wireless at 130 Mbps. Even if you can manage to connect at 5 GHz speeds for wireless, the max speed will be in the 300 Mbps range, more than 3 times slower than Gigabit ethernet. Normal "n" speeds will be about 7 times slower than ethernet.
For streaming high definition video and other demanding sources, you'll need as much bandwidth (speed) as you can get. Ethernet is always the best choice if you can possibly use it. And...there's no wireless interference on an ethernet connection.

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.

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:
http://apple.stackexchange.com/questions/70931/how-to-force-thunderbolt-ethernet -connection-when-switching-networks-without-res
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.

HT5299 Thunderbolt to Gigabit Ethernet Adapter

Can 2 Thunderbolt to Gigabit Ethernet Adapters and Ethernet cable be used to create a long Thunderbolt cable?

I do not believe so because ethernet is made to send a different format of data than thunderbolt, so it will not be able to handle the same kind of information. The adapter exists because thunderbolt can send signals used for ethernet, but I don't think the ethernet cord will handle everything that you need for all thunderbolt connections. I could be wrong though, I suppose it is worth some more research, or if you have the materials, it is worth trying.

How to use thunderbolt to gigabit ethernet adapter

hi mates. i just purchase the Thunderbolt to Gigabit Ethernet Adapter last week for my Mac Book Pro Retina. but i have no idea how it work. i tried just plug in the adapter and the LAN cable in but no luck...
Any idea how it works?

Plug in the Adapter and the cable to the adapter and the other end of the cable to a switch or router then Reboot the system. Then check the Network section in System Preferences to see if the Ethernet shows up. If it does your done. If not then you have a bad adapter, a bad cable, both bad adapter and cable or the Thunderbolt port is bad.
Or at the last a corrupted install of OS X.

Registering thunderbolt to gigabit ethernet adapter MAC-adress in the company LAN

Dear community,
I have a technical question regarding the thunderbolt to gigabit ethernet adapter!
In our company the current situation is to register the MAC-Address of every ethernet port which wants to join the local area network...so far so "normal"
The fact that the Apple notebooks have no longer an built-in ethernet port makes it complicated regarding security standards!
Is it correct that when I register the MAC-Address of an ethernet adapter to our company LAN I'm free to plugin every MacBook via Thunderbolt afterwards? There's is no "connection" between the adapter and a certain MacBook?
That doesn't sound very secure...
Can someone answer my question or does anyone have the same problem and found a workaround?
Thanks in advance,
Dennis

In OS X Yosemite, is there option to enable 802.3ad (aka LACP) to bond the interfaces?
Or is it only achievable via command line configuration?
Yes it is exactly the same process as Mavericks (and earlier). You open System Preferences, click on Network, then at the bottom click on the small gear symbol (unlock the padlock first if needed), and then select Manage Virtual Interfaces. You then add a new Link Aggregate interface which will be your bonded network interfaces.
LACP is the only type of bonding Apple support.

Thunderbolt to Gigabit Ethernet Adapter or Thunderbolt port stopped working

Hey problem if anyone can help:
I use a Thunderbolt to Gigabit Ethernet Adapter, and all of a sudden it stopped working to connect to the internet on my Macbook Air (MacBook Air (11-inch, Early 2014 with OS X Yosemite 10.10.1 (14B25)). In my system information it says it is connected even when not, see below:

Can anyone help me figure out what the issue is? Is it the Adapter, the Thunderbolt port itself? A gremlin? Thanks!

Which model MacBook Pro do you have? Does it have a Thunderbolt port? If so the TB->Ethernet adapter MAY work (although it's specifically designed for those MacBook models that lack an Ethernet port).
The adapter would certainly be the cheapest way to go - if it works. Personally, I would rather have the Ethernet port on my MacBook Pro working, but this may be an expensive fix, I don't know. If I were you, I would at least take your computer to your local Apple Store/AASP and get a free diagnosis and estimate to repair your MBP. If it seems as if it's going to be too costly, then you may certainly try the adapter and see if it works.

Thunderbolt to Gigabit Ethernet Adapter Issues!

I just bought a thunderbolt to gigabit ethernet adapter for my macbook pro. There is no connection registered. I've checked updates but I'm completely current on them. I've tried renewing the DHCP license. Can anyone give me any tips?

Have you tried to manually configure the adapter? If you enter the IP, DNS etc.. does it work?
My Macbooc Pro 17 "retina works perfectly with manual settings but, wih DHCP fails.

Thunderbolt to Gigabit Ethernet Adaptor and iPad 4

Is there a way to connect the Thunderbolt to Gigabit Ethernet Adaptor to an iPad 4?

I've never seen any ethernet adapter for the iPad. I carry an Airport Express (any portable router would do, though) if I think I'm going to be in a situation where the only internet access is going to be wired. This happens frequently when I travel in Japan.

Mbp running slow after sleep mode

My MBP runs extremely slow after sleep mode (closing lid). It seems like Safari will take up much RAM. But I use a memory freer which supposedly should solve the problem. So after all I am not sure what is the real cause and what could solve this.
BTW it runs normally after a reboot.
Mine is a mbp 13" refurb purchased in March, 2012.
Processor 2.4 GHz Intel Core i5, 4GB RAM

I too have been noticing problems in slow behavior after sleep mode. It has gotten so bad I have been restarting it regularly or shutting down much more regularly. It behaves almost like normal after a re-start.
It is almost like the hard drive is failing? Last time this happened I put a new HD in. I am usually running a large number of different programs, always multi-tasking, which has been a mac fortie. Seems worse with the last few updates. My I mac is 24" imac 2008 model. replaced drive just before apple care expired.

Thunderbolt ethernet not waking after sleep

I have the same problem with my MBP retina with Maverickks 10.9.1 losing connectivity after waking after sleep while on battery.
People from apple support don't help in solving the problem.
Does any one have the right solution? I would appreciate.
Apple please fix this problem!!!

Thanks for the link, Judy.
As far as I know, I am up-to-date as far as OS updates are concerned. At least this is what the mac is telling me when I go to updates. The article you've linked here looks to be more specifically for OSX Lion and Snow Leopard, but not Yosemite.
I would think that the likely fix here is to upgrade the firmware for thunderbolt, but I don't know how to check what macbook pro thunderbolt firmware or what thunderbolt display firmware is present. What I see in System Information doesn't match the firmware updates associated with your link.

Do you know from this info if they need updating? It's not really made clear what to look for from the article. The article refers to Thunderbolt firmware v1.0, the Thunderbolt display firmware update is v1.1.
Any ideas? Is there somewhere else I should look for this info?

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.
