Every time my new macbook air wakes up the wi-fi connection doesn't automatically connect even though I set it to auto connect

It's definitely a bluetooth problem. As soon as I turned off the bluetooth (I had turned it on to try and connect with a dock - which didn't work, but that's another matter!!), deleted and re-instated my home wifi network, all was fine.

Annoying that you can't seem to have wifi and bluetooth on at the same time, but I assume apple will supply a fix for this at some stage??

Thanks for the advice here though 🙂

Well had enough of Apple, they should reply to this forum and sort there crap.

Do they care?

Well going to order Surface Pro 3 unless apple start to listen to there customers

This is really strange for a company with such a good reputation. They have a current flagship model with a clearly demonstrable bug that a number of people are experiencing but they don't even clock it as an issue.

In an age where everything is bluetooth and on the MBA where there are very few wired ports anyway it is crazy that you have to disable bluetooth when on the battery in order to get a robust wireless connection.

This solved the Bluetooth issue for me:

Got escalated support on my Bluetooth issues. The fix worked.

This fix is for those who used the migration assistant and are having bluetooth weirdness.

Go to:

Macintosh HD->Library->Preferences

drag (the old migrated files)

com.apple.Bluetooth.plist and com.apple.Bluetooth.plist.lockfile

to your Desktop,

stop Bluetooth and logout. ( I had to restart)

Login and restart Bluetooth.

You my need to delete any devices and re-pair. If eveything works then delete the files that you dragged to your Desktop.

My Air now works as it should.

An dutch website found the solution that works (also with an terminal command), you can find the article with translation here: http://bit.ly/1z1ii5z

This solved my problem:

I had this same issue, i think, after updating to Mavericks on my macbook pro retina. After trying a lot of solutions mentioned here and elsewhere regarding bluetooth and different system settings, i tried something else because nothing of this worked for me.

Logging on my wifi router and changing the bandwidth range from 2.4Ghz to 5Ghz, and also changing the security from "WPA/WPA2 personal" to only "WPA personal 2" solved my problem. I have not tried only changing one of the mentioned settings, so not sure which one of them solved it.

My mac now autoconnects right away after sleep and reboot/power on.

Hope this helps.

I have the same problem. Apple should fix this.

May 2014 MBA with OS X 10.9.4. Connects reliably on private and public Wi-Fi access points. Private is gen 4 Airport Extreme. Never have had to turn off Bluetooth to make Wi-Fi work! Some public Wi-Fi APs are extremely overloaded, and your Wi-Fi connection attempt may just time out. At home, if you are using Timed Access Control (by hardware Ethernet address), and you forget to add the current machine, or try to connect outside of allowed time window, you won’t be successful with a wireless connection.

In System Network Preferences > Wi-Fi > Advanced… select Remember networks this computer has joined. In preferred networks, drag the Network Names into the order of most frequent to less frequent access. Click Ok, and then Apply on the outer panel.

it is very simple, and it worked for me

system reference -> Network -> uncheck "Ask to joint new networks" (Known networks will be joint automatically. if no known networks are available, you will have to manually select a network.)

I had a very similar problem, but seem to have solved it ✅

On my Macbook Pro 2014, OS X Mavericks 10.9.4, I would lose wifi every time I logged in. The wifi icon would appear connected at first, and in Network Preferences my wifi service showed a green light. But I would have no network connection - no LAN drives, no internet, nothing external. Then my wifi service would go amber, saying No IP Address. I would have to reconfigure the wifi by deleting the wifi service, rebooting, logging in, then setting up a new service.

This happened every time I logged in, and therefore every time I booted the machine up. Not satisfactory, of course.

I booted in safe mode and logged in, and the problem didn't occur. Wifi was working and all expected services resumed. I then restarted and logged in on my daughter's profile and, again, everything worked fine. Rebooted again, logged in as me again and... no wifi again. I've only had the Macbook a few weeks, and it only got like this after about 10 days, just after I got back from holiday. As it only happened on my profile on full / normal startup mode, I guessed it must've been something I'd installed...

I downloaded the free app CleanMyMac and played with the Extensions, disabling anything that wasn't essential. I would deactivate one at a time and restart and log back in again as me. If it didm't work, I'd have to go through the laborious reconfiguration process every time, which got a bit tedious. But finally, using the process of elimination, I narrowed it down to the QuickLook extensions, iWorks QuickLook Generator and iBooks QuickLook Generator. After disabling these two extensions (at the same time, I was getting a little impatient), I rebooted, logged in as me and, what do you know, the wifi works again after logging in as me every time! I then reactivated all the others I'd deactivated, and restarted a few more times, and the problem's gone. Phew!

(If I had to guess, I'd say it was the iBooks extension, because that file had a created date of around the time I got back from holiday and when I first noticed the problem. But I've had enough of playing around for now, and rebooting, so I'm going to leave them both switched off until I realise I need one of them!)

It's extension conflicts, boys and girls. That's what did it to me.

I had this problem and had pretty much resigned myself to manually reconnecting every time. I did try most or all of the solutions presented above. It was restricted to the wireless router at my home, and not any others that I use, so I didn't try the more drastic solutions since it seemed to be hardware-related. The problem started when I upgraded to Yosemite.

Then, like magic, after applying Security Update 2015-003 on 3/20/2015, it seems to be magically fixed. I would highly recommend applying this update if you are having this problem.

Had the same problem and called Apple Support this morning, which seemed to have fixed my problem. Here is what I did:

1/ Switch off your mac, plug in the charging cable. Press Shift-Control-Option keys and the power button at the same time. The light on the charging cable should change (Green to Orange or vice-versa). This will reset the hardware of the System Management Controller. So basically I did the step "Resetting the SMC on portables with a battery you should not remove on your own" in Intel-based Macs: Resetting the System Management Controller (SMC) - Apple Support

2/ Then instead of switching on the mac directly, we did another thing to reset the memory where network info is saved: How to Reset NVRAM on your Mac - Apple Support

Switch on your mac, and then immediately press Option, Command (⌘), P, and R (all 4 buttons at the same time), keep them pressed until you hear a 2nd startup sound, then you can release.

3/ Once your mac is back on, we remove the wifi network in the preference, and then we reconnected to it once again (just enter the password)

Hope this helps.

Too bad. Now it is magically broken again. I can't tell for sure but it seems like it was related to installing the update to Safari 6.0.6, of all things.

I simply used the "Assist me..." button and went through the motions and mine now works fine.

Thank you, thank you!!!!!!! Changing to WPA2 Personal did the trick.

None of the other suggestions like resetting SMC and disconnecting blue tooth worked for me.
