Mavericks: Wifi takes a while to connect after sleep

Not sure if this question has been asked, but I'm finding this rather annoying. I just upgraded from Snow Leopard and there was a feature where with one simple touch on the trackpad, you can wake your Mac up after the screen goes to sleep after a period of inactivity. I understand that this feature is no longer available after the Lion and Mountain Lion upgrades. With Mavericks, after my Macbook goes to sleep, I push a key and it wakes up, but the wifi takes a while to reconnect, however with Snow Leopard, when I woke up my macbook, the wifi didn't have to reconnect. Is anyone else having this problem? Is this a bug? I hope Apple can come up for a fix for this, because aside from the fact that I can no longer use Pro Tools 9, I'm having free "buyer's remorse" for upgrading.

Nope, turning off my other router made no difference. Even after a couple of minutes of trying to get to any web page after waking/opening the lid it can't find anything online. Had to toggle wifi off/on again to get online.
Apple, please fix this annoyance. Thanks.

Windows 7 brightness reverts back, wifi takes long to reconnect after sleep

Hi fellow members,
My brightness setting keeps reverting to max. I have tried setting via power manager and also from control panel.I can adjust but when the computer restarts, the brightnes reverts to max. It started happeing around a month ago. I didn't have these issues until about 2 months ago. I have had my x301 for over an year without issues.
Another issue I have been experiencing is that wifi takes a long time to reconnect after sleep. About 5 minutes. This is also a new issue.
I have the latest BIOS, latest power manager, all drivers are upto date. Here are the specs.

Check in the Windows power profile for the brightness issue. Windows will apply it's own at boot, then Power Manager will override, which leads to a momentary discrepancy.

HT1338 MacBook now takes 1 minute to go to sleep after all windows closed, any help to return it to normal

MacBook now takes >1 minute to go to sleep after all applications are closed. Need help in returning it to the normal 10 sec for sleep

First, Try using Disk Utility to do a Disk Repair, as shown in this link, while booted up on your install disk. You could have some directory corruption. Let us know what errors Disk Repair reports and if DU was able to repair them. This could just be a start in repairs and you may need a better utility to finish the job.
Then Repair Permissions.
No need to report any Permissions errors........we all get them.

20" iMac takes 3 minutes to respond after log in

as the subject reads, my iMac take about 3 minutes to respond to any keystrokes or mouse inputs.
Hot corners do NOT respond, and the dock does NOT respond either.
the mouse moves and the clock ticks but no inputs are allowed.
i leave the cursor on the hot corner so i know when its done thinking and finally allows me to make inputs.(thats how i know its about 3 minutes or so until it works)
all the log in items have been removed.
still to no avail.
im conducting a Verify disk and Repair disk now.
will update soon.
i google "my imac takes 3 minutes to log on" and found another person with the same problem but its a pay site, and im not paying... hahaha.
this started happening after 10.6.1

Help viewer takes 5 minutes to launch after transferring data from ibook

I have bought an iMac and transferred my data from my old iBook G4 (Tiger) using the migration assistant. The iMac is running Tiger 10.4.11 as is the iBook.
When I launch the "Help Viewer" the beach ball starts spinning. Two messages appear one after the other a couple of times:
1. *AFP connection status* (in German: AFP-Verbindungsstatus) telling me that the iMac is searching for "yrib", which is the iBook's name and
2. *Connection failed* (in German: Verbindung fehlgeschlagen)
After about 5 minutes the help viewer's initial window shows finally!
What do I need to do so the help viewer does not take 5 minutes to launch?
thanx
ps.: if it was possible to insert images I could show the screenshots...

News, news!
thanx to BDAqua, but it still is not working!
Called apple, twice. Each time 45min. couldn't help! Now here's what I did and found out.
In Macintosh HD > Library I deleted the Preferences folder. And the "AFP" message didn't show, just 6 times the other one. Which turned my access to the help viewer down to 15 seconds!
Now the problem was that I couldn't get any access to the network. And I found out where the problem lies, just I can't solve it.
In Macintosh HD > Library > Preferences > SystemConfiguration there is a file called
preferences.plist
If this file is not there (=deleted) I have access to the help viewer in 15 seconds, still needing to click 6 (it's exactly 6) times the OK button of the "Verbindung fehlgeschlagen" message.
If the file is there, it's the old game.
Anybody any idea?
I tried to figure out something using the "Property List Editor", but wasn't successful.
thanx

When I click on Firefox for the first time after I boot my PC it takes three minutes to but after that new Firefox windows open promptly.

Hello and thank you for being available to receive this enquiry.
I like Mozilla.
I like Firefox.
In recent months I have experienced and accumulation of problems. Today (September 25th, 2011) I have set about trying to deal with them.
After consulting your Troubleshooting Section I have made a range of changes that I hope shall resolve problems like freezing, unresponsive scripts, non responding windows and browser crashes.
At the time of writing I have rebooted after making those changes so I have yet to discover whether they solve those problems.
However, I have chosen o write now as I already am re-experiencing the first problem I encounter when I boot my PC, i.e. Firefox takes three minutes at least to start after I click the icon. Once it has started, however, ne Firefox windows open promptly.
How do I solve this? I rememebr a time when Firefox opened with lightning speed whenever I clicked the icon.
Thank you for your valued help and interest.
Patrick O' D.

Hello Patrick O' D,
In my experience t here are two different problems with the speed of firefox on startup
# your os and setup
# firefox - and exactly what you use with it
Some factors will be down to your OS and for instance what does start up initially, many of those factors will affect other programmes/applications and not only firefox.
Some other factors depend on Firefox and how you set that up, I always like to have the option to using Firebug but realise it cold clash with other software or slow down firefox startup so I only enable it as I need it. see for instance: https://addons.mozilla.org/en-US/firefox/performance/

Slow reconnect after sleep

My early 2006 iMac takes a long time to reconnect to my wireless network after sleeping. It finds the network no problem just takes up to a minute to "wake up" and find and join the network. Is there any way to speed up this process? My Macbook connects about ten times faster after coming out of sleep so it has to be something with the iMac and not the network.
Thanks for any help.

How to make trackpad automatically reconnect after sleep?

I have a magic trackpad and an MB Pro.
When I return to the computer after it has been sleeping overnight, the magic trackpad will not reconnect automatically. If the computer sleeps briefly, the connection is restored automatically. If the trackpad is powered off after sleep, it will reconnect when powered on. But after a long sleep, or perhaps when I have disconnected the laptop for a while I cannot easily make it reconnect.
It will not reconnect if: I click the power button, click the trackpad, select the trackpad by name and connect from the bluetooth menubar item, connect manually through bluetooth preferences, or turn off the trackpad entirely then turn it on again (force into discovery mode).
The only somewhat reliable way I have found to reconnect is: 1) turn off trackpad power, 2) go to trackpad preferences, 3) set up bluetooth device, 4) power on trackpad, 5) select continue when device is found.
When disconnected, in bluetooth preferences, the device is shown as being paired. I added it to Favorites. It is discoverable. Battery power is good.
I can reproduce the same symptoms with these steps: 1) put the computer to sleep, 2) manually turn off the trackpad, 3) turn on the trackpad again (it blinks, indicating attempt to discover), 4) wake the computer.
Can anyone help me find a less time-consuming way to re-establish a connection when the computer wakes from sleep?
Thanks,
Tom

Hi Jeff,
Thanks for the suggestion. I tried the 'root bridge' in Access Point mode but the remote devices did not try to reconnect. I also tried 'non-root bridge', 'root bridge with network clients', 'automatic' etc. I let it sit for a few minutes after each change to see if it helped.
I've going to change it to 'Access Point' again and leave it overnight to see if one of the three remote Workgroup Bridges that are currently unavailable will re-connect.
I know if I ask the site electricians to power the remote Workgroupd Bridges off and on they will connect for a while - its quite frustrating!
Thanks again

Solution for 'my mac will not reconnect after sleep'

After lots of trial and errors I found the way around the problem of dropped or very poor wireless connection after you put your mac to sleep.
I have no idea what the problem really is but this procedure has stopped me from throwing my brand new MacBook through the window.
1) Go to System Preferences -> Network -> Advanced
2) Remove any network you have there memorized
3) uncheck option 'Remember any network this computer has joined' (leave the other options also unchecked)
4) press ok and switch AirPort off ... then on (make sure you have 'Show AirPort status in menu bar' checked)
Now the only real change we've made is to stop Mac memorizing our network - but here lies the solution.
Put your MacBook to sleep and than wake it up. It will not connect to the network (none are memorized) but all you have to do is choose your network name from the list on the menu bar. It might ask you for the key but in my case it simply asks for permission to use my KeyChain (memorized WPA2 password).
Once I press 'Allow' .... it works as it should! eureka!
Do not check 'Remember this network' when asked for password.
As long as Mac does not store your network details it reconnects without problems, once you allow it to store these details, re-connection after sleep goes pear-shape.... figure it out Apple!
I hope this might help you (as it most certainly works for me)
best regards
ffar

I've run Keychain utility. I also removed (as suggested in various places) any entries referring to my wireless password in KeyChain and allowed them to be memorized again. It doesn't change a thing.
Please understand me correctly. My Airport does re-establish connection automatically (if network details are stored) but connection is extremely flaky, slow and with frequent dropouts. So the Keychain is not to blame here (I think).
If I establish connection 'semi-manually', as described in my previous post, it is perfect, just as it should be. This would indicate to me that the problem lies not with the Keychain, but in the way OS stores network details.
If I do not allow OS to keep network details - re-connection works.

Wireless network does not automatically reconnect after sleep

I have a Belkin wireless G+ mimo modem router network. When I wake the mac from sleep it does not automatically reconnect to my wireless network and i have to manually select the network from the airport icon in the menu bar and then it connects without having to reenter my secure password. How do i set the mac to auto connect to the network after sleep? There are about 6 other wireless networks in range which may be effecting this reconnection.

In may case the network was already at the top of the preferred networks list.
Based of of a hint over at MacOSXhints.com, here's how I fixed this problem:
1. In the Network references pane, delete the Airport connection that does not like to reconnect.
2. Click Apply and Quit the System Prefs app.
3. Put the computer to sleep.
4. Wake the computer.
5. Go back in to the Network pref pane and re-add the Airport connection. Do not try to connect to the network at this time.
6. Click Apply and Quit the System Prefs app.
7. Use the Airport menubar app to connect to your network.
8. Verify connectivity
9. Put the computer to sleep.
10. Wake the computer.
11. Verify connectivity
My machine now consistently reconnects when coming out of sleep or restarting.
God luck!

MacPro takes 1 minute+ to reconnect to LAN on wake from sleep

Hi - I am having issues with my MacPro when waking from sleep. When the machine wakes, it restarts very quickly, less than a couple of seconds. But I then get loads of error messages from open apps (mail/safari etc) that they have lost their network connection. It takes at least a minute for it to regain network connectivity.
I have other macs on the network and they reconnect immediately on wake from sleep so it can't be anything on the network itself.
The Mac pro has a mnually assigned IP address so its not waiting for ever to find the dhcp server and I have also trid connecting into a different port on the switch to make sure it is not a defective port.
Any suggestions for where I can look to resolve this?

I know for a fact, for me, that Vista and Intel Macs, and Mac Pro in particular, and from reading of the problems reported - in general on most Intel Mac owners (MacIntouch etc) that routers and modems were the cause of trouble.
Some newer cable modems included.
In some cases firmware updates helped. Some brands seemed to be "avoid if at all possible."
Maybe it is the Intel LAN - for Windows there were a lot of updates for my Mac Pro that reduced high latency and improved things somewhat.
... but I was seeing wake from sleep problems and having to use "network diagnostic" or just power cycle the modem and switches, which did work. I have NOT had to ONCE do so SINCE investing in new modem and switch. Zilch, nada, trouble-free.
Trial and error.
And yes, other Intel Macs are going to behave differently. They don't have the same Intel LAN chipset. Our hands are tied and I doubt Apple has done any real update.

T440p wifi slow reconnect after sleep

Hi,
I have a T440p with the intel 7260AC wifi card. I recently upgraded my HDD to an SSD and did a clean windows 7 install. Now, when waking up from sleep, it alwas takes about a min before it reconnects to a wifi network. The reconnect used to be instantaneously.
I turned off the setting in power management of the Intel 7260AC to "allow the computer to turn off this device to save power". But this didn't solve the problem. I also have the latest intel wifi 7260AC drivers 17.0.2.5.
Anybody knows what could be causing this?

Did you also install Access Connections?

T500 takes 15 minutes to boot after bios update

symptoms:
it takes around 10 or so minutes to get to the thinkpad press f1 to set up screen, after that it gives me a screen that says ME is initializing, this is after a bios update and subsequent roll back of the bios. both bios updates now give me the same result. sleep functions also seems to not work, once im into windows my t500 operates as usual.
what I've done:
in addition to rolling back the drivers Ive disconnected /reconnected the cmos battery and turned off AMT. ive also made sure that all of my drivers are up to date.
machine is a 2081-cto running on win7
anyone have any idea what i can do? i still have a long warranty but would like to solve it myself so i dont have any down time.
Solved!
Go to Solution.

Hi guys and welcome to the forum, dinny.
You might try fiddling with the BIOS setting for the security (TPM) chip:
F1 at boot to get to BIOS setup, then Security, then Security Chip.
I have mine set to "Disabled" but have seen other reports that setting it to "Enabled" can cure bootup delays.
Worth a try, please let us know if it helps you.
Good luck,
Frank
