Retina MBP 15 slow to connect to wifi after waking?

My new 2012 rMBP 15 is very slow to reconnect to wifi after waking from sleep. I've read the Apple support pages with no solutions found. It can take 10 to 45+ seconds for the wifi to lock on to my home wifi network after the computer wakes from sleep. While my Macbook Air (2010), iPad3 and iPhone 5 all reconnect almost instantly to the same wifi. Also I've noticed that after the wifi icon in the menu bar shows it's locked on there is an additional delay before actually being able to connect; like reloading tabs in safari or refreshing my Gmail inbox (in it's own tab not 'Mail app'). Any Ideas how to trouble shoot / fix this issue?
Really irritates me that this top of the line computer is slower than my other devices.....

Also SAME PROBLEM here, but also after booting, plus snail speed:

Mac Pro slow to connect to internet after waking

Since I upgraded to Lion my mid-2011 2.8 GHz Mac Pro takes about 10-15 seconds to connect to the internet. After waking from sleep in the past, I could launch my web browser and it was connected immediately. It is bad for my email. It is set to check every 2 minutes and I get a huge log of connection errors. I am using the ethernet port with a direct connect to the modem. I also have a wireless router for my MBP and it connects immediately through Airport. Why is my direct connect slower than Wi-Fi?

Sometimes if you set your Ethernet connection to Automatic, rather than specifying the speed you know it will connect at, it will spend several seconds re-negotiating speeds, duplex, flow control, etc with the connected equipment.
For fastest wake times, know what speed it will ultimately settle on, and set that as the speed it should use.
System preferences > Network > Ethernet > ( Advanced ) > Ethernet ...
set Manually: speed, duplex, and frames size.

My iMac won't automatically connect to wifi after waking from sleep mode

After dowloading the newest software update and performing a firmware update for my Airport router, my Imac won't connect to Wifi automatically after waking from sleep mode

Please re-download and install the 10.7.3 update. You can locate it at 10.7.3 (Client Combo). Follow the on-screen instructions. Then test it out, if you still have the same problem please restart, when you hear the startup tone hold down the Option Key and then choose the Recovery Partition. Then open Disk Utilities and Repair Disk Permissions 2x. Then exit DU, restart normally and re-test.

MBP very slow to pick up signal after waking from sleep

my MBP 2.33 takes about a minute after wake-up is complete to pick up a signal from the extreme N station (sits right next to it).....my old G3 ibook takes about 5sec....does anyone have a fix? the same problem? it is really annoying....it takes almost longer to find the signal then to restart...this is every time the MBP goes to sleep....
i have all the latest upgrades including the latest extreme firmware....i don't think it has anything to do with the airport, i get the same thing when connecting to my express stations....

HT4623 safari slow / crash connection during WIFI after upgrade my iPhone to ISO 6, why

It's a great OS ?

Many people are reporting the same issue. Download the update in iTunes (select "Download Only") then apply the update when the download has finished. It's safer that way.

Freeze when connecting to wifi after waking from sleep

This problem was isolated to my Powerbook when I wanted to connect to a public hotspot (it started with the latest updates). Now, however, after updating my iMac G5 with all the latest updates, it's happening to it at home on my own wireless network.
When I wake my computer, it freezes when trying to reconnect to the wireless network. The only way to get access is to hold the power button down long enough for it to shut down and then upon restart I have a workable computer that can connect to the internet fine.
I've repaired permissions and repaired my disk from the install CD. I've waited up to fifteen minutes to see if the freeze would terminate with some process timing out, but no luck.
The beachball appears when I rollover the airport status in the menu bar (and the volume and clock) but doesn't appear when I rollover other items in the menu bar (quicksilver and norton). However, if I click on anything everything freezes and the beachball "just won't quit."
Anyone have a clue what's going on? All help is very much appreciated.
thanks,
bryan

Hi bryan. Welcome to the Discussions.
1. You wrote: "When I wake my computer, it freezes when trying to reconnect to the wireless network. "
1.1. How do you know that the problem is specifically related to trying to reconnect to your home WiFi network, as opposed to some other potential cause of a wake-from-sleep freeze?
1.2. Are you using an AirPort base station or third-party base station? If third-party, what specific make and model?2. You wrote: "I've repaired permissions and repaired my disk from the install CD."DId Repair Disk find any errors, even those it may have corrected? If so, did you write them down?
3. You wrote: "The beachball appears when I rollover the airport status in the menu bar (and the volume and clock) but doesn't appear when I rollover other items in the menu bar (quicksilver and norton). However, if I click on anything everything freezes and the beachball "just won't quit.""Could be one of the other menu extras you have installed, i.e. the icons on the right side of the menu bar other than the Spotlight icon. Often menu extras are launched as Startup or Login items. My "Troubleshooting Startup and Login Items" FAQ can help you pin that down if such an item is causing the problem. Note that your AirPort connection won't work in Safe Mode, but it gives you a way of testing if the wake-from-sleep or menu extra freeze is related to a menu extra, especially a third-party menu extra launched as a Startup or Login item.
4. See if your computer's serial number is in the range specified in the "iMac G5 Repair Extension Program for Video and Power Issues" document.
5. As far as general iMac G5 troubleshooting goes:5.1. Rule out potential hardware problems. Run the Apple Hardware Test that came with the computer. Instructions for doing so will be found in the hardcopy manual that accompanied your computer. For additional details, see my "Apple Hardware Test" FAQ.
5.2. Check the diagnostic LEDs, a feature of your iMac G5. See "About the iMac G5 diagnostic LEDs."
5.3. If your iMac G5 will not turn on, see "iMac G5: Troubleshooting when your computer won't turn on."
5.4. See also the iMac Service & Support site.
5.5. Check the iMac G5 Discussions for similar reports from other users.
5.6. As a general check, run the procedure specified in my "Resolving Disk, Permission, and Cache Corruption" FAQ. Perform the steps therein in the order specified. While you've done some of these steps already, it won't hurt to double-check this.
5.7. If the computer is either under warranty or covered by an AppleCare Protection Plan, don't hesitate to take advantage of your warranty and contact AppleCare.Good luck!

Retina macbook pro can't auto connect to wifi after wifi router rebooted

My macbook pro with retina can’t automatically connect to wifi after the wifi router was rebooted. There is exclamation mark on wifi sign. As I clicked the wifi sign, it shows no Internet connects. However, It is strange there is a tick in front of my wifi name. In order to use wifi, I had to click off wifi, and then click on. The previous version, Macbook pro, has no problem like this. I had deleted all files under wifi library, but still fail. Appreciating for any way to solve it!

Unable to Connect to WiFi after iPhone power off; WiFi & internet are working with MBP; common problem, no solutions?

Here's my setup: Internet <> Comcast/xFinity supplied cable modem <> new Apple Time Capsule <> iPhone 4 & MacBook Pro (see below for hardware details)
Internet on my iPhone 4 has been acting slow since yesterday evening. My MacBook Pro was running fine, but just to be sure I checked the Comcast website to see that I have only used 50GB of my allotted 250 GB of data for the month, so it's not that.
I decided it must be a problem with just my iPhone, so I opened up the multitasking bar and quit everything in there manually, and then I held the on/off button, and slid the slider to power off. When I started back up, I could not connect to the same WiFi I had just been using. I tried to reconnect and nothing. I tried to forget the network and try again, nothing. I tried to reset all network settings, nothing.
I have tried all the steps listed here: http://support.apple.com/kb/TS1398 "iOS: Troubleshooting Wi-Fi networks and connections"
Toggled WiFi off and back on
Made sure I am in range of the router (it's about 8 feet away and my iPhone reports full signal from the network)
Made sure all the hardware is connected and on
Checked other devices (I'm successfully connected with my MacBook Pro right now)
Checked for router firmware upgrades (I have a new Time Capsule from Apple with the current 7.5.2 firmware which I've been using for a month)
Restarted my device (again)
Checked that the network is available (it does show on my iPhone)
Restarted my Time Capsule
Checked my router configuration as described here: http://support.apple.com/kb/TS3727 "Wi-Fi: Unable to connect to an 802.11n Wi-Fi network" which involves simply checking to see that WMM is turned on, also stating that WMM cannot be enabled or disabled for Apple's AirPort products.
Reset my network settings (again)
I have searched and searched for fixes to this problem, and I have additionally tried:
Enabling/disabling Airplane Mode
Disabling any network password protection/encryption (no luck), re-enabling it (no luck)
Changing the network password
Checking for hardware addresses present in iOS Settings > General > About (they are present and not zero'ed out)
Switching Bluetooth off (nothing) and back on (nothing)
....and probably a few other things I can't think of right now
I have yet to try:
The "Freezer Trick" which apparently involves chilling the iPhone to get a temporary fix?
Restoring the iPhone (I would really rather not)
A different WiFi network (other than my own Time Capsule home network or guest network, both of which give the same Unable to Connect error)
So, after all of that, are there any more ideas? Is there a reliable solution to this issue? So far I've just seen a lot of "mess with the settings," "the freezer trick worked," and "blame it on the iOS 4 update."
Here are my hardware details:
iPhone 4; iOS 5; 32GB; AT&T; no cellular data plan (July 2011)
TimeCapsule6,113; Firmware 7.5.2; 2TB (September 2011)
MacBook Pro 3,1; Mac OS X (10.7.2); 2.4 GHz Intel Core 2 Duo; Hi-Res Display; 4GB RAM; 500GB HD (August 2007)
...and the Time Capsule config:
http://cl.ly/BCUt

Ugh. Apparently "messing with it" is still the answer. I decided to try the LinkSys router I was using before I bought the Time Capsule, and my iPhone connected with no problem.
I went through the steps again, and after rebooting my Time Capsule this time, I can connect again. The troubling thing it that this started with a power-off of my iPhone. No changes or installations, just a reset. Am I going to have to reboot my Time Capsule (which has no power switch, just a cord I have to unplug) every time I reboot my iPhone?

HT1145 Macbook slow to connect to wifi

Hi, I have a new Macbook Retina (2013) with Mavericks. Recently it has started becoming really slow to connect after shutdown/sleep. Once it does connect, the speed is good, although it periodically disconnects and reconnects, which often interrupts uploads/downloads. Has anyone else had this problem?

LG G3 cant connect to wifi after Lollipop update

After getting the update a couple days ago, I have not been able to connect to my WiFi. Had no issues prior to the update. I have done everything Ive read online, with no success. I am assuming this is one of the many Lollipop bugs? Has there been a fix discovered yet? Obviously this is a big issue as I don't want to use my data. Any help would be appreciated! Thanks.

I can connect to wifi, but it is so slow as to be unusable. I contacted Verizon via Chat and they sent me here. They also said, " I do show we are currently investigating that issue."
Hopefully, an update will be coming soon. I do not want to go through the hassle of a factory reset, especially considering what I have read from those that did and are still having problems.

Macbook Air Doesn't Connect To Wifi Upon Waking

Since installing Yosemite, whenever I wake my Macbook Air from sleep, it doesn't connect to Wifi. In order to get it to work, I have to open up Network Preferences/Assist me/Diagnostics and go through that process (then it works). Any suggestions on how to fix this?

Hey there alhs77st,
If you are still having this issue where your computer is not connecting to your Wi-Fi network when you wake it from sleep, I would use the following article to help resolve that. This section in particular:
Wi-Fi: How to troubleshoot Wi-Fi connectivity
Symptom: After restarting or waking from sleep, my computer might not connect to the Internet
Thank you for using Apple Support Communities.
All the very best,
Sterling
