WIFI does not reconnect after MBP sleeps

When my new MBP Retina wakes up the wifi dies not reconnect. I have to "Turn WIFI off" and back on again. My late 2011 works without a problem on the same netowrk. I have been to an Apple Genius four times. I have even returned the MBP and got a new one. Same problem....
Any suggestions. Could it be the Linksys wifi router? SOuld I get an Apple AirPort Extreme????
THanks
Monty

I can not believe it, a new wifi router fixed it (so far)
I've let my Mac slap about 10 times and it reconnected w/o an issue

WIFI does not reconnect after a standby

Since I installed "OSX Mavericks" on my MACBOOK AIR, the wireless network does not reconnect after a reboot or standby. I need to disable the wireless and reactive for the connection resumes!
Thanks for your answer...

Trash your Bluetooth preferences, restart your Mac.
Open Bluetooth Preferences (Apple Menu, System Preferences, Bluetooth)
Remove any audio devices that are shown in the upper section of that list.
Pair your Bluetooth Speaker or headset device and then connect and disconnect it.
Open /Library/Preferences/com.apple.Bluetooth.plist
If the LastA2DPDevice item is present, then you know you have just paired a A2DP device. You need to trash your Bluetooth preferences and restart your Mac again.
The problem is caused by an interaction with Bluetooth and specifically Bluetooth devices that use Advanced Audio Distribution Profile (A2DP) which is used to stream bluetooth audio from devices such as Bluetooth headsets and Bluetooth speakers.
The problem is caused when the Mac goes to sleep and wakes back up. It tries to connect to the A2DP device that was last used by the Mac. If that device is not powered on or is not in bluetooth range, it will keep trying to connect to that device (for an unknown amount of time). While it is looking for that Bluetooth device, the 802.11 wifi is also looking for the last wireless router or access point and fails to find it.
Why the wifi is unable to reconnect after waking from sleep is not exactly clear because wifi is a different protocol than Bluetooth. One hint is that it only seems to fail with wireless routers that run on the 2.4 Ghz band. That is the same frequency that Bluetooth uses (even though Bluetooth hops through different smaller bands within that frequency.)
I do not have the problem when at home and connected to my Airport Supreme Wireless AC router which is running on the 5 Ghz band.
To prove this, here is what I did...
1. Go to a location where you are having the sleep / wake wireless problem and take your Bluetooth speakers or Bluetooth headphones with you.
2. Now while at that location, Connect to the wireless network there.
3. Turn on the power to your Bluetooth device (speakers or headphones).
4. Turn Bluetooth on and connect to your Bluetooth device.
5. Put your Mac to sleep for 45 seconds (that is enough time for the Macbook to shut down power to Bluetooth.)
6. Wake your Mac back up and you will notice that there is no problem reconnecting back to the wireless network.
7. Now turn OFF the power to your Bluetooth device and put your Mac to sleep for 45 seconds.
You will see that your MacBook will not connect back to your wifi wireless network after it wakes from sleep.
That is because it is looking for your Bluetooth device that it cannot find.
Note that this test is only valid if you are using a Bluetooth device that uses the A2DP protocol. I did my tests with a Bose Soundlink Mini speaker.
I am connecting to a Netgear N300 Wireless Router (WNR2000)

Airport Extreme "N" does not reconnect after MBP wakes from standby/sleep

I have a closed network and do not have any problems with the new AirPort "N" base station except this one. When I open the lid on MBP the computer does not pick up the signal. I have my closed AirPort network in my list of Preferred Networks and yet I have to choose "Other..." from the drop down menu and type in the network name and password before to get it to connect. I do not have this problem on my PowerBook so I have only to assume that I have an incorrect setting on my MBP. Any suggestions? Thank You in advance.
MacBook Pro 15" 2.4Ghz 160GB HD Mac OS X (10.4.10)

I had this problem on one of my Airport N units. I deleted the base station from the preferred networks and also from the (I think) two locations from the keychain.
I then connected again and had the Airport added to the keychain again and since then I haven't had the problem.

OSX 10.9.1 macbook pro 13 retina - wifi does not reconnect automatically when waking up from sleep mode since I have a Bluetooth apple magicmouse

Hello,
My config is OSX 10.9.1 new macbook pro 13 retina (2014).
The wifi does not reconnect automatically when waking up from sleep mode since I have a Bluetooth apple magicmouse.
It was not the case before I bought the BT mouse.
Is this problem between Wifi and bluetooth coming from the OS?
Is there a fix already available or scheduled?
Thanks

Hello alexandrefromfrance
Check the Symptom: The network connection drops unexpectedly section for steps on what to do when your MacBook Pro does not connect after waking from sleep. I have also quoted the section on troubleshooting the issue as well.
Wi-Fi: How to troubleshoot Wi-Fi connectivity
http://support.apple.com/kb/HT4628
Symptom: After restarting or waking from sleep, my computer might not connect to the Internet
After waking from sleep or starting up, your computer may not show that it is connected to a Wi-Fi network.
After start or wake, your computer may indicate that it is connected to a network, but does not connect to the Internet.
Solution
Use these steps if your computer does not automatically connect to your desired Wi-Fi network.
Check your TCP/IP settings in the Network pane of the System Preferences. Click the "Renew DHCP lease" button
Choose System Preferences from the Apple menu.
Choose Network from the View menu.
Select Wi-Fi, then click the Advanced button in the lower-left hand corner of the screen.
Click the TCP/IP tab from the top of the screen.
Click the "Renew DHCP lease" button.
Select the Wi-Fi tab and view your Preferred Networks list.
Select each network and click the minus sign to remove those networks from your Preferred Networks list.
Click OK and close the Network preferences.
Remove your stored network passwords using the Keychain Access Utility.
Open Keychain Access from /Applications/Utilities. Your window will look like this:
Remove your AirPort network passwords from the login keychain: Select the "login" keychain from the Keychain sidebar. Click the "Kind" column to order the list of keychain items by their type. Remove all entries of the kind: "AirPort network password".
Remove your AirPort network passwords from the System keychain: Select the "System" keychain from the Keychain sidebar. Click the "Kind" column to order the list of keychain items by their type. Remove all entries of the kind: "AirPort network password".  Note: The above steps will remove your Wi-Fi network passwords. If you do not know them, or if your network does not use passwords to restrict access, you should contact your network administrator.
Restart your computer.
Join your Wi-Fi network. You will need to enter your password for your network again if it requires one.

External hard-drive does not reconnect after sleep

Hi everyone
I am trying to use my Energy Saver to SLEEP my iMac after 1 hour. It goes to sleep no problem, but on wake-up, my external USB hard drive does not reconnect. There is also an error message that I didn't disconnect the drive properly. I fear this may be one of Mac OS X's "features". Has anyone encountered the same thing?
On a side note, I also find that my USB keyboard does not always reconnect as well. I use a windows USB mouse that I have connected to wake it from sleep, however my USB keyboard (the small one for Macs), sometimes does not allow me to type unless I unplug it and back in.
Another point of note is that both the HD and the keyboard are connected to the iMac through a 7 port USB hub.

I think this might be the issue. If the iMac is waking back up, it will likely be waking up this HUB, but the HUB might not be re-initialising the connection between OS X and the external drive or the keyboard.
After waking the iMac, if you unplug the external drive from the HUB, then plug it back in again, does OS X pick it up again? Have you tried plugging the external drive directly into the iMac and then testing what the result is?
If you read back on what you've said, you pointed out that you have a USB mouse that you use to wake the iMac from sleep. Is this mouse directly connected to the iMac? If so, it surely can't be a coincidence that a directly connected USB device can wake the iMac from sleep, but any USB devices connected to the iMac via a USB HUB cannot.
I would suggest you test the drive as it is directly connected to the iMac. I would complete the same test with the keyboard too. I think you'll find it's the USB HUB.
I hope this helps.

Airport does not reconnect after standby...

Is anyone having issues w/ wireless not reconnecting after standby? In order to resolve the problem, I have to turn airport off then back on. Most of the time I can get back on using on/off method, but seldomly I have to reboot. This is my config:
SSID is not broadcasted, using capital letters and numbers for SSID Name.
WPA TKIP set for router encryption. WPA Personal selected on Airport.
I don't seem to have this problem on my Macbook running Leopard, so I'm pretty sure it's hardware/driver related to my Macbook Pro. I have to keep tabs on this, but I almost think this problem does not appear when a network SSID is broadcasted and/or unecrypted. It could be my imagination but not sure.
Any ideas or same issues out there?

I always have the same problem; I assume it has something to do with the fact that I regularly switch my cable modem to "standby" when done surfing the internet. Seemingly Airport loses the signal (or whatever) because the modem isn't feeding a signal being in standby mode? When I turn the modem back on, I have to turn Airport back on as well. So far, I've just felt it to be a small inconvenience.

Airport Extreme in extender mode does not reconnect after main router reset.

I have an Airport Extreme 4th Gen (extender). set to extend the signal from an Airport Extreme 5th Gen (main). Whenever the main router resets (after reconfig, etc) the extender does not reconnect. I would have to restart the extender before it will connect again to the network. However, my Airport Express set to extend will automatically reconnect. Is this a settings issue? Please advise.

Ok, well I am hoping you are not doing a re-config of your 5'th gen all the time? This should only be done very rarely... we're talking like less than once a year for many people. Unless there's something else going on there, I wouldn't worry about it if you have to power-cycle the 4'th gen once in a few blue moons.

Broker does not reconnect after db restart

Hi,
we have a enhanced cluster with two brokers running on solaris 10. the ha store is a oracle 10 db. after a db downtime of 10 minutes the cluster could not reconnect to the ha store. we have in the broker logs the following SQLExceptions. it was impossible to use any imqcmd. we had to terminate the two brokers. after starting them everything was running fine, no more exceptions. why do the brokers not reconnect after a db downtime?

Hi Tom,
near the end of the pasted exception it says: Closed Connection.
i think this is the cause of the failure. this is expected because the oracle data store is down. The problem is, that after the db was back online. the broker continued to throw the same exception. i expect, that the broker throws away the closed connections and reopens new ones to continue his work.

The wifi does not work after update 5.1.1

Express does not reconnect after reboot of Extreme

My extreme is conencted (via ethernet) to my router (bridge mode)
My Express is connected to Extreme to expand wireless network (bridge mode)
However when i reboot the extreme, the Express is no longer visible
I have to reboot as well. is this normal?
Also, logically (as per above config) the extreme & express are part of ONE wireless network
So a device conected will "roam" between the 2 as if it's only 1 wifi point (?)
However when i connect a wireless security camera, it shows me express & extreme seperately (eventhough same name & login)
and I have to choose to which one to connect.
IThis means if it's connected to Express & Express stops working, then
it will NOT got directly to the extreme (eventhough it's well in range)
Plsd to hear
Egon

Apple wireless mouse does not reconnect after changing batteries

The wireless mouse on my iMac quit working after I changed batteries. There was no response to mouse clicks, or movement, or scrolling. Eventually I connected a USB mouse, did an orderly shutdown of the system, rebooted, and the mouse started working again.
The long story ...
The first time I encountered this problem was the first time I changed batteries in the Apple Wireless Mouse that came with the iMac 3.06 GHz Intel Core 2 Duo I purchased in January 2010. (The OS is 10.6.2 without updates.) I switched the mouse on, the green light on the bottom of the mouse blinked for awhile (at least a minute), but clicking or moving the mouse got no response. The new batteries were Eneloop 1.2v rechargeables. I tried clicking and moving the mouse several times over a period of ten or fifteen minutes, nothing.
I started searching the web for clues about what to do and maybe a half hour or so later I tried the mouse again and it worked.
A few days later I wanted to see if the problem was reproducible. I don’t remember now whether I removed the batteries and reinserted them or just power cycled the mouse, but again the mouse quit working. The green light would blink for awhile, about a minute, then would go off completely. I took this to mean the mouse was searching for the Bluetooth network, not finding it, and giving up. Over the period of half an hour or more I tried switching the mouse off and back on several times. The green light would blink, but nothing more.
I started searching for tips about reconnecting an Apple wireless mouse after changing batteries. I ran across a (2005) discussion on MacRumors forums titled “Wireless mouse troubleshooting problem...” The symptom was a little different, the mouse was partially functional. In this discussion some contributors thought weak batteries could be to blame. So I replaced the rechargeable batteries with new alkaline batteries. Still no go.
I attached a USB mouse and looked at the Bluetooth preferences pane. I was surprised to see the Apple Wireless Mouse was listed there with status paired and connected. Still at this point switching the mouse off and on would produce blinking light on the mouse, but no functionality.
I tried various things in the Bluetooth preferences to see if I could get the mouse connection to restart. When I tried to delete the mouse connection there was an alert saying this was the only mouse connected, was I sure I wanted to disconnect. I said yes, but nothing changed in the Bluetooth preferences pane. I tried unchecking the Bluetooth “On” box, etc. Eventually I only succeeded in losing response to the keyboard as well.
I attached a USB keyboard, shutdown the system, and rebooted. I didn’t know if having the USB keyboard and mouse plugged in would interfere with the wireless devices, but it did not. After the reboot both the wireless keyboard and the mouse were functional again.
Since then I have tried removing the batteries briefly a couple of more times to see if the problem would recur. I actually put the rechargeable batteries back in. Both times the connection was remade as soon as I clicked the mouse. I also now have seen the Apple support article about setting favorite Bluetooth devices http://support.apple.com/kb/TA21371 . I'll try that if this issue comes up again.

Hi, is this a question" Post?
or are you just offering an insight into your Mouse Issue?
Generally and at times we all have little idiosyncrasies appearing with the running of our Macs.
I use the same Logitech BT with my MBP. MB & iBook..(not at the same time) Only ever had one issue
and the cure was to completely Delete the mouse from BT -> Repair Permissions & Reboot then Re Install the BT mouse..Ihave just put a new set of batteries in the Logitech (only 2nd set ever)...L

Playbook WiFi does not work after update

Hi, my name is George and I am from Greece. I purchased recently a second hand Blackberry Playbook and the first thing I did was a software update. After the update the device booted normally but it couldn't detect any of WiFi (802.11b/g) access points that I have home and in my work (3 different hotspots in total). I searched on the support site for the problem and I saw that some others have faced the same issue and they fix it by doing a full wipe out (factory reset). So I tried the same with no success, now my device boots and I am unable to complete the first registration that can only be done via WiFi. I also tried to re-update the device several times using the latest Desktop Software, but the result is always the same no Wifi detected.
I contacted the Greek subsidiary of the store that the device purchased and they told me that I must contact with RIM central branch because the RIM support policy about this product (Playbook) is that customer gets support directly from them. The store that the Playbook originally purchased is Expansys France and I have scanned the invoice as evidence of legal purchase and valid warranty.
Please advice me how can I get support for the product because I sent an email and the reply tells me that I need to submit BlackBerry inquiry via approved channel Blackberry Playbook wifi problem. I don't know how to do this so if anyone can provide me with a link I will be grateful.
Thank you very much.

You can find the Playbook support numbers here.
www.blackberry.com/playbook   click on support
Finally, at the state you are now, find an open free hotspot (no password required, such as a Starbucks or McDonalds) to do this initial setup stage.

SMTP with SSL does not work after MacBook sleeps

Hi,
I have a brand new MacBook running Leopard, using Mail for a work MS Exchange account and a personal IMAP account. I connect to both mailboxes over SSL for security and this all works perfectly fine. When I close my laptop however (i.e. send it to sleep), it seems to corrupt my SSL session for the IMAP mailbox. Upon waking the MacBook up, the Exchange account work perfectly fine, as does the IMAP mailbox for receiving, although sending mail always errors out. If I quit mail, restart it and then click "Connect" on both (incoming and outgoing) of the SSL notices, everything starts working again.
Is there away to auto-Connect to IMAP mailboxes without the SSL notification or to recover SSL sessions after they time out?
Cheers,
Rob

My wifi will not work after compurter sleeps

Wifi works great until computer goes to sleep. When I turn it back on, it can't connect. Right now I am restarting the computer everytime. Very annoying. This only started this week. It has worked well since Christmas. This is an imac bought on Dec. 23 of this year.

This is a know issue. The work around solution is only letting the display sleep, set the options in System Preferences - Energy Saver - Power. If you don't want to use the work around then simply cycle the Wi-Fi when you wake up the computer. You can do this by click the Wi-Fi symbol in the menu and then choose Turn Wi-Fi Off and then Turn Wi-Fi on.
BTW PLEASE PLEASE PLEASE fill out your profile. Not having a profile completed makes it difficult for those trying to help you. You can do this by clicking Your Stuff in the upper right of this page, then click Profile and filling in the pertinent information.
