Transmit rate is sometimes slow after waking up from sleep

I have been having intermittent problems with my wifi network at home ONLY on my MacBook. I have several other devices accessing the network, both wired and wireless. What will happen is after sleep it gets really slow or inoperable access to the network. If I turn airport off and on it works better. I have Applecare and have gone around and around with Apple about this. They even tested my card for a day in their store and had no problems. I updated my system software, deleted all network prefs and keychains, etc. etc. This was with an AEBSn (not dual band). Finally I decided to upgrade to a Time Capsule so I could get dual band functionality. I am using the old AEBSn to extend the wifi to a guest house and a very old 802.11g Express to only join the network (not extend) to connect an older usb printer to my network.
I was extremely impressed with the Time Capsule for a few hours today and then I had the SAME PROBLEM. This time I knew about the option-clicking of the airport menu. My normal transmit rate is 130 for the MacBook where it is sitting now. I quickly checked it when the slowdown happened, which is the last time I woke it from a longer sleep and the transmit rate was 1! I turned the airport off and on and it jumped back up to 130 and acted happy again. What is going on here?

I don't know what changed over time but I don't have this problem anymore. The Time Capsule has been great. I have it on top of a free-standing bookcase to avoid overheating and give better reception. It has been wonderful. I only have a few dead zones in obvious places (like right next to exterior walls that are steel-framed).

Hello, I have a macbook pro late 2011 15 inch with 4 gb ram. My macbook runs extremely slow when logging in after waking up from sleep, locking up and I am unable to use the keyboard. Is there a fix?

My macbook runs extremely slow when logging in after waking up from sleep, locking up and I am unable to use the keyboard. Furthermore, when just using safari to watch streaming television, my computer gets really slow, and locks up, and the dock appears blank and I sit here frustrated. Anytime i wake up my computer, my keys don't respond and I've waited at most 3 minutes untill i can type in my password. Even sometimes when i type in my password and hit enter, it takes forever to open up my mac. I have barely used any storage in my macbook, since i only use it for college, and I have run clamscan wiht no viruses showing... Any ideas?

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, or by a peripheral device.
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 andWi-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.

W510 eSATA/USB2.0 combo port does not respond after waking up from sleep mode

Has anyone tried to connect external DVD/CD player or burner to the eSATA/USB combo port and experienced very slow system performance after waking up from sleep mode? It might takes minutes to launch an application program that usually takes just few seconds. My W510 can not even restart. It will just stop at the Thinkpad logo if I tried to restart after waking up from sleep.
The funny thing is if I moved the external DVD/CD player to the USB2.0 port in the back, everything went back to normal. I don't know if this has anything to do with the fact that the combo port has something to do with eSATA.
Thanks

It seems that this problem is unique to my system. I am hoping that one of the Mac Guru's will have at least a pointer in the right direction.
Thanks.

Ethernet interface disappears after waking up from sleep

Hi guys,
I've been trying to debug a networking problem without any luck and I think it's about time I ask the forum for help.
My ethernet interface no longer works after I wake up my computer from sleep. I have no idea why.
Before sleep:
# ls /sys/class/net
lo wlp2s0 enp3s0f2
After waking up from sleep,
ls /sys/class/net
lo wlp2s0
Here are the list of services I have running.

Furthermore, plugging in the ethernet cord after the computer has started doesn't connect to the internet, even when I have the ifplugd service running. I am forced to run:
sudo ip link set enp3s0f2 up
sudo dhcpcd enp3s0f2
However, I can't run these commands after the laptop wakes up from sleep since it no longer sees the ethernet interface.
I am thoroughly confused. Please help me.

It seems to be fixed after the kernel update. On an related note, I've switched from using dhcpcd to netctl. I've enabled netctl to automatically connect to the network using:
# systemctl enable [email protected]
# systemctl enable [email protected]
So when I check for the status of the ethernet profile, I get told that's it's inactive.
#netctl status ethernet-dhcp
netctl@ethernet\x2ddhcp.service - Networking for netctl profile ethernet-dhcp
Loaded: loaded (/usr/lib/systemd/system/[email protected]; static)
Active: inactive (dead)
Docs: man:netctl.profile(5)
But I turned off the wireless, so I must be connected to the ethernet, So how do I know which profile I'm connected to?

Lose connection to external USB hard drive after waking up from sleep

My Mac lost connection to the external USB hard drive after waking up from sleep. I can still see the folders in the hard drive in Finders, but when I double clip a folder no file within the folder is displayed. I have to reconnect the hard drive with iMac to read its contents.
May I ask how this happens and is there a solution?
I'm using Paragon NTFS for Mac OS X to read from and write to NTFS format of USB external hard drive.
Thanks!

... I un-ticked the "put hard disks to sleep when possible" option in the Energy Saver panel in the System Preferences, and it seems the problem is solved. will have to sleep and wake up my iMac to further verify if this is the solution ...
Alternative advices are always greatly appreciated!

Track pad freeezzzz after waking up from sleep mode

HI
i have OS X Ver 10.5.1
i have enough ram, disk space, and have the 2.4 GHz Core 2 Duo processor.
but when my mac wakes up from sleep the track pad is just not behaving properly, i.e it keeps jumping positions and freezes until i restart. if this continues it will be very frustration to use leopard.
also i did not get the option to archive and install at the installation so i cant even down grade, this is one of those time i trusted that everything will go right and looks like the problems just begun.
please help me !

Hi,
I have almost the same problem with my T540p, except that there is no internet connection not only after waking up from the sleep mode, but also when starting windows and sometimes the internet connection will get suddenly lost during normal windows run.
I tried installing all kinds of drivers - latest from intel, latest from lenovo update (which is always different version from the one from intel), some older versions. Nothing helps.
Re-enabling the WiFi device like Aaziz1982 suggested, doesn't help.
Here is a more detailed description of my problem: http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/T540p-WiFi-Connected-no-internet/m-p/177818...
Does anyone have other suggestions?
Thank you,

Compaq C700 - CPU fan not running after waking up from Sleep mode

Hi guys,
Waking up from Sleep mode does not start the CPU fan.
Kernel: 2.6.32-ARCH
KDE : 4.4
Let me know what other details you need.

I was having the same problem after installing mountain lion.
What i did was in Finder went to /Library/Preferences/SystemConfiguration/ and deleted all the networking plists (refer screen shot). Then restarted the Mac and in Network Preferences reconnected to my WLAN.
That solved the problem.

Dead USB controller after waking up from sleep

Hi,
I posted this a while back but the issue is still unresolved. I am experiencing USB port sleep issues after upgrading to Tiger (currently running 10.4.8). Sometimes the build-in USB port that has my keyboard connected to literally wakes up dead from sleep. Here is the error message from the Console log
(XX-Computer kernel[0]: USBF: 24445.528 AppleUSBOHCI[0x15ab800] Watchdog detected dead controller (hcca #: 56759, hc #: 64465).
This happens with no set pattern, sometimes it wakes up fine, other times the port is dead. A restart is required to bring it back to life.
Any ideas why this is happening? If I plug in my keyboard to the other USB 1.1 port everything works fine (the port remains dead until the next restart). I also have a USB2 PCI card that works with the keyboard without any dead port issues but I can't use it for waking the computer (does not trigger wake up), but I simply prefer to use one of the equipped USB ports for my keyboard.
I have 2 external FireWire HD's connected at times, one daisy-chained to an external FireWire CD Burner. I have a USB 1.1 hub connected to the other equipped USB 1.1 port, and a USB 2 PCI card installed.
I run system maintenance tasks frequently (Onyx) and repair permissions prior and post SW installs and updates.
Thanks for any input.

It seems that this problem is unique to my system. I am hoping that one of the Mac Guru's will have at least a pointer in the right direction.
Thanks.

HP ZBook 15 freezes after waking up from Sleep Mode

I've got a brand new HP ZBook 15. It arrived with Windows 7 and a HP Windows 8 DVD. I installed windows 8 on it immediately using the DVD and installed all drivers with the HP Support Assistant. Apart from having a lot of problems with the Ethernet, which are now partially resolved, I've got a huge issue when putting the Laptop into sleep mode and waking it up after 1-2 hours. Everything will start normal, and I can see the start screen image (the image which appears before you log in with your PW or PIN), but it will then immediatly freeze. This can only be resolved with a restart. Sometimes, even after restarting, I will be able to log in normally, but the system freezes again after reaching the desktop. I've tried talking to HP Support but they just gave me some drivers to install (i.e downgrade my drivers) which did not resolve the issue. BIOS is L70 Ver. 01.07 Does anybody know how to resolve this?

Hi BananaCode, To get your issue more exposure I would suggest posting it in the commercial forums since this is a commercial product. You can do this at Commercial Forums.
Thanks.

I can't be the only one with this issue. MacBook Pro Retina Late-2013 WiFi disconnects after waking up from sleep.

Did anyone buy a MacBook Pro Retina 13" from Best Buy this Black Friday?
I'm having an issue where the WiFi disconnects after the MacBook wakes from sleep but only after a couple of minutes.
Once the WiFi disconnects, I can't reconnect to the same network and sometimes it won't find nearby networks.
I have to turn off the WiFi and wait for at least 5 seconds before turning it back on for it to auto-reconnect to my home network.
If I wait less than 5 seconds, it will continue to attempt connection to the home network but won't connect.
I've tried reformatting and deleting my network configurations as well as resetting my modem, power cycling it, etc.
I am using 2Wire Gateway modem/router from AT&T on b/g network.
I've tried connecting to a friend's network under Time Warner Cable and the same issue occurs.
I exchanged the MacBook at a Best Buy for a brand unopened one (I hope) and the same exact thing happens with this new one.
Really, I can't be the only one with this issue. Unless in a 0.00001% chance I received two defective units in a row?
Please.. does anyone have a clue why this is happening?

You're definitely not the only one. I have the same issue. I spent 6 hours over multiple days on the phone with Apple support trying a variety of things (some of which are mentioned above), and none of them worked. They finally sent me a replacement laptop. I made sure to try it periodicaly as I was moving files and installing applications to see if I ran into it again and things seemed okay at first but now I am running into the same issue and it is terribly annoying. I've got 5 other devices that connect to the same router and I've never had this issue with any of them.
My router is a Linksys E2000. I haven't tried changing the router channel but I have tried to cnnecting to other networks in the building I live in and I have run into the same issue there.

Hi, Lately many times my MBP15 shuts down a few second after waking up from sleep mode. Any ideas why? I think it happens everytime I try to open safari right away...

I think it happens everytime I try to open safari right away, but I'm not sure. After shutting down it automatically restarts and gives me a message Ÿour computer had to shut down because of a problem, press any key to restart..." and when it comes on again it gives me an option to send an error report to apple.
Any ideas?
Thanks

Yeah your Mac is having a Kernel Panic and the option to Restart the system when that happens is checked. So the system Restarts Automatically. Uncheck that option. For some unknown reason it is located in the Energy Saver applet in System Preferences.
As to the ROOT cause it could be software or hardware problems. There should be a Kernel Panic report in the console logs.
But if you do a search of these forum you'll find many that are having these restarts waking from sleep. So it would seem to be a hardware problem.

After waking rMBP from sleep and typing password, rMBP goes back to sleep after a few seconds and won't wake for about 7-8 seconds.

Absolutely embarrassing. What is going on here? When will we see a fix?

This happens rarely but consistently! I't seems to happen about 5% of the time waking from sleep. It MAY be more prone to happen if I had been moving with it in my bag, but it can happen at any waking time after any duration of sleep.
