Thunderbolt ethernet not working when computer wake up from sleep.

thunderbolt ethernet not working when computer wake up from sleep.
it will not happen in Mountain loin.

I had this problem on SL and on Lion as well, and it occures for WiFi and Ethernet connections.
In fact the internet connection was not broken as I could ping the destination usin the IP (not DNS name).
In this case the problem was related to mDNSResponder task which handles all dns queries.
It was the most frequent problem in my day to day work with SL and now Lion. It was never fixed by any patch from Apple. I tried almost all voodoo including fresh install, all possible config changes - no solution.
The only version with no problems related to network was 10.5.8. All the other versions had issues of different kind (WiFi instability (lost signal), DNS problems (for wireless and wired connection) sometimes associated with machine sleep and wake up and sometimes with no reason.
QUESTION: Is your problem independent of the access point / router you connect to.
I must say networking was (and still is) the weakest part, besides the other OS X weaknesses I experienced during 4 years of OS X usage.
No problems in the same network with Linux or Windows beeing ran natively on my iMac So hardware is OK.
Software is of poor quality. Not much more to say in this matter.
I found a very interesting article dated 1996 about programming which I think is still valid.

Internet connection not working after computer wakes up from sleep. OSX Lion

After upgrading to Lion, I noticed that my internet connection doesn't work when I wake my computer from sleep. I have to turn off the WiFi connection, turn it back on and it will work. I guess this is a glitch that will be fixed later on. Just wanted to point it out. I don't know if someone else is having the same problem? I am not very happy with the upgrade to Lion, things seem to be slower, I've had several freezes requiring to reboot. I guess Lion needed a little more twicking before release. Not worth the $29.99 price tag.

Internet connection does not work when Macbook wakes up from sleep

I recently installed MAC OSX LION. After that whenever the macbook pro wakes up from sleep, the internet connection does not work. I get a message 'DNS lookup failed'. I have to Turn off the WIFI and turn it back on every time. Has anyone come across this?

Same problem here. But I am afraid it has nothing to do with Safari because I don't even have Safari open. When it wakes from sleep, it has no internet connection and i cannot get me mail unless I shut wifi off and then back on. This happened back at the start of Snow Leopard too and it was something Apple eventually fixed.

Firefox not working when PC wakes up after sleep but Chrome is working.

When laptop wakes up from sleep, already opened tabs in Firefox are not getting connected to internet. After two minutes opening a new Firefox window is connecting to internet. But this problem is not happening with Chrome.

When you are doing this, set the drive to never sleep, slider completely to the right and display sleep to something like five minutes. Or just hit Control-Shift-Eject, to sleep the display. Uncheck "put the hard disks to sleep..." That said, the firmware on the externals may be spinning them down. But this shouldn't be happening if they are being written to.

Wireless not working after laptop wakes up from sleep mode

After my laptop wakes up from sleep, the wireless network stops. Even when the wireless is enabled, it is unable to scan the wireless networks. In order to make it working again, I have to restart my laptop. Here are some of the details that might be useful.

Well, the above two links have the problem similar to mine but not exactly. In first one there is a problem with network manager - that it is unable to restart after coming from sleep mode while that is not a problem in my case and I tried all the solutions provided in the second link, but didn't work.
What I figured is when I execute '#pm-suspend' and then close the lid. Then, after I open the lid I wireless works fine. 'pm-suspend' is not invoked if I close the lid. So I needed to invoke the above command when an acpi event is generated when I close the lid. So here is what I added in the /etc/acpi/handler.sh file
button/lid)
case "$3" in
close)
(sudo /usr/sbin/pm-suspend) #added
open)
This works fine for now. Still, I don't know why this solution works - Why executing pm-suspend solves my problem?

My HP Pavilion dv6-2153ee recovery is not working when i choose it from boot menu selection

my HP Pavilion dv6-2153ee recovery is not working when i choose it from boot menu selection . it's run but then the windows run without running recovery. help me please?

Hello Tajamal,
Welcome to the HP Forums!
I understand the webcam isn't working since upgrading to Windows 8.1. I would have to suggest returning to Windows 8 since there are no 8.1 drivers, as indicated here: HP Pavilion dv6-7043cl Entertainment Notebook PC Drivers
Please let me know if you have any other questions.
Have a wonderful day!

My iphone is not working when i plug off from charger.

My iphone is not working when i plug off from charger. Evenmore when it is on the charger and it still not working, it asks to connect to i-tunes but i can't and i can see only emergency calls. What should i do?

If it only works when connected to a charger, that would indicate a battery issue.
As for the other issue... do as it suggests and connect to iTunes then restore. There is no logical, intelligent expectation that anything on the device can be accessed as long as the "Connect to iTunes" screen is displaying.

OSX 10.7.5 How can I make my computer wake up from sleep?

My computer won't wake up from sleep whether I put it to sleep by a hot corner or by closing the lid. Has anyone a solution, plezase?

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, or by corruption of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and Wi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

Thunderbolt Ethernet not working after Yosemite upgrade

Upgraded last night to 10.10, and now my Thunderbolt Ethernet adapter has no MAC address, and my MBP appears to think the cable is unplugged - it's not, and worked fine when the MBP was running 10.9 yesterday. Things which haven't worked:
Deleting and re-adding via Network Preferences
Changing default IPv6 to Link-local only
Rebooting with the thunderbolt adapter in
Rebooting with the thunderbolt adapter not in
Switching the thunderbolt adapter to the port further from the hinge and back again
Unplugging and replugging the ethernet cable
Plugging the ethernet cable directly into the wall jack instead of the hub it has always been plugged into
Unplugging and replugging the Thunderbolt
Changing Location to "Work" from "Automatic" and back again

the link provide above leads to http://plugable.com/2014/10/31/os-x-10-10-yosemite-ethernet-adapter-problems-we- can-help
...but these seem to be all 3rd party USB ethernet adapters and nothing to do with the Thunderbolt adapter of the thread - or am I missing something?
I have the same blooming problem, it seems to be totally hit and miss whether the adapter works or not.
I thought is was a faulty adapter, so even bought a second one for my MacBook Pro, so a bit more profit for the most profitable company in the world for a non working device. My ethernet cable works fine to an old apple USB adapter but is 90% useless with Thunderbolt.
Renewing the DHCP lease occasionally works, but totally unreliable, at the moment it fails.
Still looking for a reliable solution.
Come on Apple, please sort this out, you have a connector policy of turning everything you can into adapters and dongles rather than building them in, so you end up with a slim laptop and a bag of adapters to carry around, and then when they don't even work - doubly annoying.

10.9.1 thunderbolt ethernet not working

Upgraded to 10.9.1 and now when utilizing Thunderbolt to Ethernet I am getting message
"Thunderbolt Ethernet has a self-assigned IP address and will not be able to connect to the Internet."
Any suggestions?

Same here, Late 2013 13" MBP, with the dual Thunderbolt.
Upgraded to 10.9.1 and now neither TB registers with my ethernet adapter. The same adapter works fine in my wife's 2012 13" MBP with 10.9.0.
Something in 10.9.1 has killed both TB ports.

Thunderbolt ethernet not working after upgrading to Yosemite

After a very long and frustrating 2 days I have managed to upgrade my MacBook Air (13 Inch, Early 2014) to Yosemite. I have the official Apple thunderbolt to ethernet adapter but System Preferences/Network reports that the cable has been disconnected. It has not and other devices connected to the ethernet cable work fine. Any suggestions to get it working? Anyone else having the same problem?

I have a similar problem. My Macbook Pro Retina 15" (1st generation) can no longer connect to my university network through a Thunderbolt-to-Ethernet adapter since upgrading to Yosemite. (Actually, OSX 10.9 on a different machine altogether also has the same problem -- tested and verified.) I tried multiple dongles and multiple Ethernet cables, and finally called our tech support. We found a workaround for the problem by purchasing a USB to Ethernet adapter, but this now means that instead of a single device chain leading into the laptop, I am now using multiple ports. I hope a patch for this is in the works.

Macbook Air thunderbolt ethernet not working after 10.8.3 update

Hi,
Thunderbolt Ethernet for my Macbook Air (11-inch, Mid 2012) stopped working after installing 10.8.3 update. I am unable to conect to my router via thunderbolt Ethernet connection port.
Anyone else having the same issue? Any recommendations?

Unplug your thunderbolt adapter. Restart the router.
Go to your Mac and go to System Preferences >> Network
Use the - button in the lower left corner to delete your Thunderbolt to Ethernet adapter.
Now plug your thunderbolt adapter back in and use the + button to add "Ethernet Thunderbolt" to your list of connections. Move it back up in the order of network preference you want.
Your network access should now be reset.

Javascript (in Firefox 3) takes several minutes to start working when computer wakes from sleep, Mac OSX 10.5.8

Whenever I wake my Mac from sleep, with Firefox having been left running, some parts of Firefox take several minutes to start working again. These include switching between open tabs and any website functionality that uses javascript, eg gmail. This has gone on through many updates of Firefox. If I quit Firefox immediately on waking the Mac and restart it, everything is OK.

The following worked for me:
http://support.mozilla.com/en-US/questions/684867
"Problem: I had the same problem but with mac osx 10.5.8, Firefox 3.6.6 sometimes prints and sometimes does not, but the preview was always blank and I could not save to pdf file.
Solution: I downloaded Firefox 3.5.10, installed it on my desktop and opened it, tried print preview and it worked, quit Firefox 3.5.10 and ran 3.6.6 and voila! print preview is working fine and I can save to pdf fine.
I guess running 3.5.10 fixes the profile in a certain way. I have no idea how that happened but it worked."
