Q: Wifi disconnects after sleep and takes long time to reconnect with Mavericks

So far this worked for me. (deleting com.apple.Bluetooth.plist) Hopefully it keeps working!

Today wifi failed again, after to pair my MBPr to some bluetooth devices.

The event sequence went as follows:

1. None Bluetooth devices -> Wifi wakes up OK

2. After pair Apple Magic Mouse -> Wifi wakes up OK

3. After pair Jabone speakers -> Wifi wakes up OK

4. After pair Belkin speakers -> Wifi takes too long to wake up!!!

5. After unpair and remove all devices -> Wifi keeps wrong

6. After delete com.apple.Bluetooth.plist -> Wifi goes OK again (even without reboot)

Apple can't say that is due to the belkin device because it works great with my iPhone 4S. Lukilly I don't really need to use the belkin device with my MBPr but Apple must solve this issue.

I have been having the exact same issue for about rwo months now with a 2013 rMBP I bought new in October.  I have spent an exhorbitant amount of time working with a Senior Apple Advisor and to no avail.  Apple seems baffled by this problem and the Senior Advisor consulted with Engineering many times about my problem and said they could not duplicated it.  For me the trouble occures after pairing to a Jam Classic bluetooth speaker.  If I delete the bluetooth.plist file the problem is solved, but only until I repair the speaker.

A soft connection reset can sometimes fix this issue.

Turn off WiFi
Open Network Preferences
Select WiFI in left hand pane and click minus button.
Click Apply
Click plus button and rebuild connection as prompted.

Hi Martin,

there is absolutely nothing in the log. The Wi-Fi is On, not showing any signs of error. It only does not see any of the networks around. The first entry appears only after it connects, that it is registering etc.

Fairly, as stated already before, in the long term nothing helps except patienly toggling the Wi-Fi occasionally with toggling BT On/Off and wait it turns on correctly. I have posted also here but again this (https://discussions.apple.com/message/24176836) is my separate thread, where I write everything I have tried including 2 clean re-installs. I do not know if the BT is the trouble but I do not have any BT device connected nor nothing paired from the history. Just nothing, it is turned of and unused.

The biggest problem is that the error cannot be re-produced on demand. Sometimes it works, sometimes it does not. I can be any help to anyone at Apple if only they take this issue and look deeper in it as this clearly must be either driver or OS issue.

I've tried almost everything described in this thread to solve the problem, but to no avail.

However, what has actually helped me is to manually change the wifi channel on the router, using the wifi router UI. I'm using Netgear Genie WNDR 3800.

My iMac, mid 2011 is the only Apple device which is loosing the wifi connection. Apple TV, two iPhones, iPad all work fine. So does the MacBook Air after the upgrade to Mavericks. However, none of these devices use Bluetooth. Only my iMac does.

I'm not an IT professional, but I think that the problem is in Mavericks, given that all other devices work, and only my iMac is using the Bluetooth. Also, the only thing that changed after the problem appeared is Mavericks.

I have had exactly the same problem mac book pro retina 13 inch late 2013 loses wifi when lid closed and put to sleep especially when bluetooth is on.

i noticed this dosent happen when power is connected and so have unchecked put hard drives to sleep when possible and enable power nap when on battery.

this seems to ahve soleved the problem

will report back how i get on over the next few days

this worked for me thanks!

This helped for me.

Turning my "BLUETOOTH" off has totally rectified the problem on my MacBook Air.

Happy days :-)

I've had this issue as well since upgrading to Mavericks on MBA 2013 version.

I've tried a number of the fixes including turning Bluetooth off (not BT as I'll explain), sleep changes etc. This morning after more fiddling my computer did connect automatically to wireless. I have Bluetooth on, it slept last night and I'm now going insane

I'm in the UK and BT is our main Internet provider (so as not to confuse the Bluetooth acronym). They offer a roaming wireless service that is provided from each of their Wireless routers (unless disabled). So if my Router's wireless connection wasn't connecting I'd find a web portal asking me to login to a BT wireless hotspot. I've taken this off my network settings now as it just added time to fixing the issue each morning. This would connect each time my normal wireless connection disappeared.

This problem will come back - its intermittent and although I know many people are fixated on Bluetooth being turned off as a fix - it can't be the whole story as it doesn't fix it for everyone all the time.

My conclusion is there might also be an encryption problem to be solved. Bluetooth may be partial causation but might be unrelated for some instances.  I can go weeks without it occuring and then it just appears (without any config changes).

For me this problem has been solved by replacing by basic Netger router with an Apple AirPort Extreme.  I took the computer to the Apple Store to have this problem looked at and of course while I'm in the store, the problem would not occur.  I figured the only differene was that I was on a different network.  So, I tried an AirPort Extreme router and problem solved.  The Apple Store people thought it must have been a security issue between the Netgear router and Mavericks.

Go to System Preferences -> Network . In the left pane click on gear icon -> Set Service Order -> click, drag and drop Wifi above the rest especially Bluetooth -> apply and then see if Wifi still gets disconnected

I went so far as to remove all services except Wifi.  It did not help with this issue.

Update on my solution:  to date I am still having no issues when on my AirPort Extreme router. However, over the weekend I went to a family member's house and used the computer on his network which is not an apple router, and the problem came back!  So, to recap: I do not experience the Bluetooth/wifi problem in the apple store on an apple network, and I do not experience the problem at home with an apple router. Everywhere else I have connected to a non-apple network i consistently get the problem. Can any of you network experts out there think of what would make the apple router different from other routers on this issue?  What would be the link between Bluetooth and wifi that is different with an apple router?  Even though my AirPort Extreme router solved this problem for me at home, I would still like to get to the bottom if it since it is quite frustrating anytime I use the computer on a non-apple network.
