MacBook Air :: What Made It Finally Connect To Wifi After Sleep
Apr 19, 2012
I finally got my mid 2011 MBA to connect to my preferred network when waking from sleep. It is something you may have read elsewhere but I can confirm it worked for me. You have to disable the "deep sleep mode". When a Air goes into deep sleep is when (for me) it failed to wake my network back up. I switched off deep sleep and not only does it wake up faster it wakes up connected to the Wi-fi network. How do you turn off deep sleep? Using the terminal commandÂ
sudo pmset -a hibernatemode 0Â
If you are like me you may say what is a terminal command? Go to spotlight (that magnifying glass icon top right corner of your screen) and type terminal. Click the Terminal next to Applications. Copy paste the command I posted above and supply your password if you have one. What this does is disables the deep sleep mode that the Air's use for maximum battery life while left sleeping and on battery. This is why my Air always connected to wi-fi when it was plugged in to power, because it never enters deep sleep when on external power. Now the computer goes to sleep and wakes up as intended and no more turning airport on and off to start wi-fi back up. Try for yourself and if it does not work...your Air is broken (I guess). Â
If it did not work and you want to put the computer back to the way it was go back to terminal as above and then copy and paste this command back in.Â
sudo pmset -a hibernatemode 3Â Â
In case you worried your computer now does not sleep, it does. It goes into plain sleep mode as the old Macbooks that awoke just fine used to do.

Does anyone else notice the MBA takes a long time to reconnect to your wifi network after awaking from sleep? I'd say it takes 10-15 seconds vs. a MBP which takes less than 5 seconds.Not a huge deal, but I'd say it's one of the slowest notebooks I've used to reconnect to a wifi network.

I have a pretty old Titanium Mac Book that runs OS 10.3.9. It's a moderately slow machine, but still works- and although I realize that it won't be able to stream video or anything, I figure it would work for email, and basic web browsing- But I'm wondering if it's going to be compatible with any new products such as a USB wifi antenna - because the room where I want to use it won't alow for an ethernet connection-  Also, will the old 10.3.9 OS allow me to connect wifi to the newer airport extreme base stations?Â

I don't know what's wrong with it.My ipod touch connects just fine and yet when i try to connect my new macbook it won't allow me to connect.I've never owned a macbook - so i have no idea how to fix this.
I currently have the network setup assistant running and configuring - but it's been about an hour and it hasn't done anything.Is there something else i need to do?

It is on my home network which I have been using for months. I have made no changes to my router or network setting. Other devices will still connect to the wifi with no problem and I connect through the ethernet connection with no problem. I have disabled the wifi and restarted my computer with no luck.

I'm basically trying to make a "save as" version of a project so I can change what I have without risk of losing everything I've done. But every time I save a new version of the project (and even rename it, store it on another drive, etc.), the changes I make to the new version are also made to the original.I'm also not getting the popup "duplicate project" window (which should give me a choice of where and how to save the project) I'm supposed to get when I click on "Duplicate Project." How can I simply save a fixed version of my project?Â

I am not sure if this is related to the other wifi issues posted on this thread. I am hoping it is an easy Leopard configuration thing. But my wifi used to work perfect--until I patched my OS version. Now, whenever open the lid, it can never connect to my wifi router immediately like it used to do. It spends cycles hunting, and I end up having to manually go into network preferences and try a few times to connect, including rekeying the password.

Evey time it goes to sleep or I turn it off it forgets the fact that there is any wireless around. I have to look for the networks. Then if it wants to will find them and trying to connect to my own wireless network (apple extreme) is a challenge. I do have parallel desktop installed, could that be the problem?
Here is some info:

There is a problem of a periodic signal loss. The reason for this is the password reset network settings in the airport. It happens randomly during sleep. The system log says only connect and disconnect from the network. What may be the reason?

I have the original 1st generation Core Duo MacBook, and I'm having some trouble with the wifi. Often, when I go to a new location like to a library or a friend's house, I won't be able to connect to the wifi (it will timeout) or it will connect, but the signal strength will be very weak or the internet will be very slow.
It's not that it's out of range, I'm in an area that's known to have wifi and others around me can pick it up fine with full strength. At home, my wifi works fine, but the router is in the same room I use the computer in.

My Macbook Pro has been great since I got it last June. Recently I just did an software update that I believe included something with the wifi/airport setting. Now I cannot connect to ANYTHING. My work wifi network I can connect with my iPhone and others have connected to my "puck" wifi from CLEAR. I have ruled out that the connections I am trying to connect to are the problem. When I try to connect with my MBP I it tries and then gets greyed out in the top with the exclamation point. It says:Â
Alert: No Internet ConnectionÂ
When I have tried to "fix" using the normal processes when clicking on it it says it cannot help me. I have researched and cleared the network settings in the keychain access. There was another thing that said to delete the apps.apple.alf.pfile or something like that but when I went to the area in Library/Preferences that file didnt exist. I need my Macbook to access the Internet.Â
I am running Mac OS X Lion 10.7.3Â It is a 2.3 GHz Intel Core i5 4GB 1333 MHz DDR3

I have a MacBook Air that is refusing to connect to the home network. The MacBook is a late 2011 model 3,1 core 2 duo, 4Gb RAM 128Gb SSD connecting to a virgin media super hub. Tried the hub with and without enabled security. Sometime the MacBook sees the hub when you try to connect it immediately errors with could not join..... A network timeout occurred. Â The Bluetooth seems to be just as flaky. Won't connect to my iPhone?Thinking the wifi/Bluetooth card may be dodgy. Â

I have a MacBook Air. WIFI has been working just fine, until yesterday, after I turned it off to use a LAN network via USB adapter. Ever since I have not been able to reconnect via WIFI, and I get the message (that a lot of people get) of "wifi has the sel-assigned IP address and will not connect to the Internet." I've tried restart, shut-down and wait, tossed preferences, removed preferred networks, renewed DHCP Lease, all repeatedly, but to no avail.Â
the strange thing was, today I was somewhere that had 801.11g and 801.11n networks, and I was able to connect on the g network, but not on n. And what was more strange, was that the same Ethernet Lan connection I used yesterday no longer allows me to connect to the Internet, even though the sidebar says Ethernet was connected and showed green light.Â
At the same time my iPhone and iPad can both connect to any of the networks.Â

Just bought my daughter a 13.6" 2.4 GHz MacBook Pro, and it connects fine to my Apple TimeCapsule in 2.4 GHz & 5 GHz mode with no issues using DHCP. However, when my daughter brings the laptop to her mother's house, and attempts to connect it to her Cisco 2Wire160 (802.11g using WEP) router with DHCP, it doesn't connect. She can select the router, but it doesn't prompt for a password.
When she goes into System Preferences -> Network, WiFi say something about a self-assigned IP address of 169.x.x.x., when that router is chosen.
If I have her delete the router from Advanced in the Preferred Network section, and then connect to any of the neighbor's routers, she's immediately prompted for a password. Attempting to re-connect to the 2Wire160, still doesn't prompt for a password.

I received my new Macbook Pro 13 inch on Wednesday this week. I was so excited to get it, however, it's not all been rosy!!! I turned it on and expecting it to connect to my wifi straight away but oh no, it was having none of it. I tried for 3 hours to figure out a way to connect it but it wouldn't work.I have since tried again yesterday and today but still no joy.It can't be the router as our iphones are connected to it fine.

I have recently moved to a new place and am now using a shared wifi. To begin with it was slow and kept dropping in and out, now it won't connect at all and says there is no IP address and the wifi icon has an exclamation mark. I can still connect my personal hotspot from my iphone to the same computer, however.

This is driving me crazy. I have tried so many fixes but nothing has worked. Every time I hibernate / sleep my 2012 macbook air, the wifi drops and takes at least 20 minutes to come back on when I open the laptop again.Â
I can reboot, turn the wifi off and on, change preferences...everything. Nothing works.

Putting her MacBook Pro/Maverick to sleep works fine, but when she raises the lid the Wifi connection is broken, and cannot be acquired unless she reboots. Does a switch exist for this anywhere?

Ok so we've all heard about the issues with airport on the MacBook. Well I've had mine for about 3 yrs now and this problem with airport wifi connection has progressively been getting worse over the last yr. I took the MacBook in last week and they wanted �170 to put in a new network card and antena. Bit much I think.! So they told me I could buy a �35 USB wifi dongle thing.

Yesterday I purchased a new Macbook Pro and brought it to use on campus today and although the wireless status bar said I was connected I wasn't able to navigate the internet. It would sometimes prompt me to enter my atlas login information but after clicking submit wouldn't do anything or the apple homepage on safari would open and I wouldn't be able to navigate to anywhere else.I called the help desk and was told to go to the tech room, after going there and was told I couldn't be helped I was sent to another lady who called someone and by merely restarting my laptop I was able to navigate the internet. After that I went back to the building I spend all my time in and the I was back to square one. I have searched numerous forums with similar issues and attempted as much as I understood and could and am still unable to connect.Please help, I need so badly to be able to connect to wifi on this computer while at school!

Since about 2 days ago, my wifi on my Macbook air running 10.7.3 Lion does not connect to any wireless network, whether it's naked, WEP encrypted, or WP2 encrypted. It fails on 'Network Settings' Network Status step (Wi-fi and Wi-fi settings are 'green'). In fact, I can use my other Macbook running 10.7.2 Lion as well as my Android phone to connect to the wireless networks my Macbook air cannot connect to. Â
What I find really weird is I tried re-installing Lion on my Macbook air using the 'command-R' key on bootup. I was able to successfully connect to my WEP encrypted router during the re-install. But once it was done and re-booted I once again cannot connect to any wifi.Â
So something really funny is going on while OS-X is fully booted on my Macbook air.Â
This is pretty crummy situation to be in because the Macbook airs don't have a default ethernet jack built into it, so the computer is somewhat useless.

My father made a wifi network for our house. When I got my Macbook Pro in December 2011, I had no problem connecting to it. As soon as I turned on my computer, I was automatically connected. However, for at least 2 months now, I am unable to connect to my network. When I try connecting, a message will pop up saying: "Unable to join network, Connection timeout occured." I talked to someone from AppleCare, and they told me since my router to the wifi network was not from Apple, I would have to unplug the router and turn off my computer. Then wait 2 minutes or so, and turn everything back on. Is there anny way I could try connecting to my network without turning off my computer?
