MacBook fails to connect to wireless network after sleep mode

My MacBook fails to reconnect to my wireless network after waking up.
After turning on my MacBook it establishes a decent connection to whatever wireless network I choose (mostly at home). When I close the lid and open it again the network connection is lost and is only reestablished after reboot.
Hopefully someone has a solution as this is very annoying.

Instead of a reboot go to your Wireless Menu icon and select "Turn Airport Off".
Wait a second and "Turn Airport On."
For me this has been a problem for about 2 years. This is much faster than a reboot!

It's the same issue.

G580(2189) Wi-Fi doesn't want to connect to a network after sleep.

Hi.
My G580(2189) don't want to connect to a Wi-Fi network after sleep. It's not just my network at home, but at work and other points of interest as well. It usually after a reboot it works again. And sometimes, al tho rarely after just going back to sleep and waking it up again.
I've tried updating drivers, but always been confused to what hardware is being used in this laptop since it just says "broadcom" or something.
I did update my device to Win 8.1. But I'm pretty sure I had this problem before that tho.
And I tried to contact Lenovo support, since I'm not really a forum-kind-of-guy. But their support site it so confusing for simple person to person contact.
Tanks in advance for any advice.

hi Paverx,
Welcome to Lenovo Community Forums!
Can you try enabling Hybrid Sleep and see if that works,
Let me know your findings.

Unable to connect to wireless network after 10.4.8 update

Hi Guys,
I use Macbook which I have just updated to 10.4.8. After doing the update I can no longer connect to my wireless network. On 1st boot Airport asked to update the keychain. I said yes.
Selecting my network, and entering the WPA key results in "Password for this network is incorrect" which is a load of rubbish as I can connect a PC Laptop to it perfectly. I have restarted the router, put in the key in caps and lower case, and still always the same error message.
Has anybody else experienced this? If so, does anyone know how to fix it?
Thanks,
Paul.

I just brought home a new Macbook with the 10.4.8
system software. I had to reconfigure my wireless
router to "open system" - it still required the WEP
key code, but when it was configured as an open
system instead of an automatic system it allowed the
Mac to connect.
My other computers still work fine with the new
router configuration.
Macbook Mac OS X
(10.0.x)
10.4.8 came with your new macbook? or did you update?
the only reason i ask is this was a question from a day or two ago, people were wondering if it were abnormal that new macbooks were still shipping with 10.4.6 even though 10.4.7 was out, and some predicted that once it went to 10.4.8 the shipping software would be updated to the new update

Brand new macbook pro cannot connect to wireless networks

The first time I called apple tech, they thought it was a problem with my internet provider. I've called 4 times now, and I'm still getting the runaround.
I have an old (2001) G4 sitting right next to my macbook pro which can see numerous wireless networks and connect to them all. A strong connection at that. However, my brand new (refurbished) Macbook Pro Intel etc,.... supposedly best computer ever made, . . . . can see the same wireless networks but has never been able to connect. As a student, I saved for a year to buy this notebook so I could work at cafe's & study with my friends. My friends with PC's can all connect to these wireless networks. My friends with older, less expensive notebooks can connect no problem. I have never been able to connect. Bought this peice of junk 2 1/2 months ago - only because I didn't want to be stuck at home anymore with my desktop. Stupid me to trust apple.
I wish I could get my $ back, but I'm now being told that it's 30 days too late. Before they told me it was a minor thing and some software update could fix it. I did as told. downloaded and installed their 10.4.8 thingy - deleted all the keychain stuff - nothing. same peice of junk.
Now they are telling me to go back to the genius bar where folks are just rude to me and tell me they can't help me becuase I bought a "refurbished" model that didn't even save me $25. What do you know.
Anyone having problems like this? Anyone out there who can help me?

Okay,
I apologie for calling it a peice of junk. I know you all probably worship this machine. I'm just really frustrated. I noticed that this is a very common problem - though most of the posts identical to mine have dissapeared from apple.com - this well known defect is all over other discussion boards and websites like macdefect, etc,....
So, can any of you tech gods help me with this very well known, common problem that I haven't been able to fix with 10.4.8 upgrade?
Thanks for your time and assistance,

New Macbook Pro. wont connect to wireless network once it has had a update

hi
bought a new macbook pro last week, when you first start it up it connects fine to a wireless network, but once the software update is compltete it says that there is an error trying to jion network. there is already a powerbook g4 connected to the network and a pc. i have re installed tiger and it can connect fine until the software update has restarted the mac and the same error is back again. do i re install it again and never update it or is there a simple way to correct the fault

My girlfriends New Macbook Pro is doing the same thing. I does connect to non-secure wireless connections such as at the airport but doesn't connect to her home wireless connection that is run by an SBC DSL 2WIRE gateway. I can connect fine on her old IBM laptop that I am on right now through this network wirelessly.
There has to be a fix for this?

Can't connect to wireless network after Mac OS update

I just bought a mid-2007 Macbook (2x2 GHz, 2 Gb), which came with OS X 10.5.1 installed.
I connected to my wireless network (WPA2 Personal) without any problems and ran Software Update. This worked fine, including updating to 10.5.3.
But now I can no longer connect to the wireless network. It either times out when I enter the password, and/or crashes the Network Preferences.
I tried re-installing the system, but the installer said it couldn't install on this mac. That happened both with the 10.4.6 discs I got with the Macbook and with the 10.5 disk that came with my iMac.
Any suggestions?

Hi tankfield
Sandra has already addressed the reason why you can't use the wrong CD-ROM to re-install OS X.
However, the reason you had problems in the first place is that the 10.5.3 update contains some unacknowledged (by Apple) issues which cause flaky wireless connection. The same problem also appears on the latest update of Tiger. Apparently, not everyone is affected, but if you are then it's a real issue.
There appears to be no single solution, just several suggestions. Off the top of my head, these are:
- In your wireless router, switch off Mixed mode and only use G or N
- Change the wireless channel so it doesn't class with the neighbours router
- Don't use WEP encryption, only WPA or WPA2 (good advice anyway)
- Put AirPort first in Network Preferences, and your home network first in Preferred Networks
- Create a dummy location which is a clone of Automatic
.... and many more - none of which worked for me.
Finally, today I came upon this one which (so far) seems to be working.
- Start up Utilities/Terminal and type this command EXACTLY followed by return:
sudo sysctl -w net.inet.tcp.delayed_ack=0
(It will ask for your password)
In the unlikely event of this working for you, you will need to re-apply each time you reboot.
Good luck
Bob

HPC8180 Printer wont connect to wireless network, after firmware upgrade to Wireless Router

My HPC8180 has been connecting wirelessly since I bought it sometime ago. I recently had to upgrade the firmware on my Netcom NB9W wireless router and since then my HP wont resolve to the wireless network.
I run the Wireless Network wizzard on the printer, select the correct SSID and enter the WEP key as per instructions.
It then will not connect.
The summary I print out says it passes everything except:
No Filtering = Fail
Connected = Not Run
Signal Strength = Very Low (which is strange because it's about 10ft from Wireless Router).
Other networks detected matching your network name (SSID) = No
Summary says:
Network Name (SSID) altnet (correct)
IP Address = Not applicable
Configuration Source = Not applicable
Communication Mode = Infrastructure
Authentication Type = Open System
Encryption = 64-bit WEP
I have NOT turned on mac address filtering
Any ideas??
This question was solved.
View Solution.

Your router appears to be a DSL modem router. Those can be tricky to connect to. Also, WEP can be problematic and is no longer a good security measure. WEP can be broken in about 10 minutes with freeware from the internet.
Let's do three things:
1. Change to WPA or WPA2 encryption. You can make up your own password. Make it 13 or more characters, numbers and letters, upper and lower case.
2. Reset the Network Defaults in your printer (Setup > Network area).
3. Attach to the router in this way:
Sometimes DSL providers have more control over the router than the printer likes.
- Unplug the telephone line from the router
- Turn the power off on the router, wait 30 seconds, then turn the power back on.
- Go through the normal process of connecting the printer to the device (Wireless Setup WIzard)
- Now find the IP address of the printer (it should be on the self-test printout), type it into a browser.
- On that screen you will find a Networking Tab, then on the left Wireless, then the IPv4 Tab.
- On this screen you want to set a Manual IP. You need to set an IP address outside the range that the router automatically sets (called the DHCP range). If you know what that is, set an IP outside that range but no higher than 254 (the last number in the address).
- Use 255.255.255.0 for the subnet (unless you know it is different, if so, use that)
- Leave the gateway and DNS blank
- Finally, plug in the phone line, reboot the router and test.

Macbook just stopped connecting to wireless network all of a sudden

Hi,
I was using my macbook on the internet this morning with no problem.
I then put it to sleep for a couple of hours by closing the lid.
Since then it is no longer connecting to my wireless network.
Message "None of your preferred networks are available".
It keeps prompting me for a password, when I select the network, which all of a sudden is no longer valid.
I know the password is 100% fine as is the router itself (3 other devices currently using it).
Reboot the laptop several times but same thing every time.
The OS X version is 10.6.7.
Anyone else seen this issue?
Cheers.

All too frequently, I'm sad to say.
Sometimes you can recover by rebooting the MacBook. Sometimes by rebooting the router. Sometimes by changing the router channel number. Sometimes by renaming the network. Rarely by hurling the MacBook at a wall in frustration.

MacBook won't stay connected to preferred network after sleep

Anytime our MacBooks (good ole white) go to sleep, they wake up and need to be connected to the preferred network again. I attempt to only connect with Preferred Networks, but that does not resolve the issue. I only want it to see the preferred networks and it continues to sit around while I tell it where to link.
Any ideas? I have a netgear router and 2 Macbooks that are having the issue. I just upgraded to Mountain Lion and continue to experience the same problem... lovely grayed out signal and a prompt to connect to some network.
Thank you for any help you can offer.

Airport stays on, but cannot see networks after sleep mode

i have had this issue for only one week (after 3 perfect years of wireless internet). the problem... the subject section says it all. so far, the only way i get to have internet again is to restart my ibook. works perfect until the next post-sleep mode.
does anybody know why this is happening?
ibookG3 Mac OS X (10.3.9)
ibookG3 Mac OS X (10.3.9)
ibookG3 Mac OS X (10.3.9)
ibookG3 Mac OS X (10.3.9)

I found the solution for my G3 in other threads. Hope it works for you:
1. From the Finder window
2. Go to folders: /System/Library/Extensions/
4. Scroll down until you can see:
"AppleAirport2.kext"
"AppleAirport.kext"
5. Move "AppleAirport2.kext" file to the trash by clicking on it and then hitting command and back-space (you will then have to enter your system password)
NB: This leaves you with "AppleAirport.kext" - the more recent file in the Extensions folder)
6. Restart
7. Fixed!

Unable to connect to wireless network after software update

on updating the software on my Ipad 3 I am unable to connect to my office wireless network

Look at iOS Troubleshooting Wi-Fi networks and connections http://support.apple.com/kb/TS1398
iPad: Issues connecting to Wi-Fi networks http://support.apple.com/kb/ts3304

Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

Apple TV does not re-connect to wireless network after standby

When I 'turn on' my ATV after it has been in standby mode it will not re connect to my wlan. I have to do a restart of the ATV box before it will find the network again. Needless to say, this is a complete pain....anyone else suffer from this or know a fix ?
Thanks,

I removed the file "com.apple.networkConfig.plist" from the Library\Preferences folder and restarted. Now my network is found after restarts and wake from sleep.

Airport Express doesn't connect to wireless network after firmware update

Hi,
I just updated the firmware on my Airport Express to 6.3 and now it will no longer join the network. I have tried reseting to the factory defaults and Airport Utility accepts all the information and shows the unit with a green dot next too it. However, the unit is still flashing amber and in the final step where the Utility tries to save the configuration the update fails and I get the following error message:
An error occurred while reading the configuration.
Please make sure your AirPort base station is plugged in and in range of your computer or connected via Ethernet and try again. (-6753).
I am using an old style AirPort Extreme as a base station.
Can anyone help?

Wow, really no suggestions yet? This is a first for me, on the Apple Discussion boards!

Messages won't connect to AIM network after sleep. What's up with this?

I am having some problems with Messages. I just upgraded to Mountain Lion yesterday and I have found out that after my Mac Mini (Mid 2011 model) goes to sleep, Messages refuses to connect to the AIM network. I used to have a similar problem with iChat, but I was usually able to get it to connect again by turning the WiFi on on my Mac. (I use and Ethernet cable to connect to the wireless router.) However, that does not work with Messages. The only way I have found to be able to connect is to restart the computer. Any ideas?

Hi Malik666,
Actually I am set to Threaded view.
However a thread that gets a bit longer than this one will stop showing the individual posts in this staggered manner.
At the top of an Apple Support Communities page use the "Your Stuff" items > Then Preferences in it's menu.
This takes you to a two tabbed page.
You need General Preferences.
It may pay to start another thread about the computer losing it's Communities Login.

Devices fail to connect to iOS7 hotspot after sleep

I'm new to hotspotting and this may just be one of those annoying issues.
I set up an iPhone 5s (iOS7.0.2) as a wifi hotspot. I connect my laptop and ipad, everyone is happy. The laptop or iPad goes to sleep and when it awakes it can't find the iPhone hotspot. The hotspot is not even listed in the available network pulldown menu. Reset the iPhone and the devices discover the hotspot, everyone is happy agian until someone goes to sleep.
What am I doing wrong.. besides using a klugey apple product

Hello Yositimy,
Thank you for using Apple Support Communities!
It sounds like the wifi connection from your personal hoptspot is not being spotted when the connected devices go to sleep, then wake up later.
I want to recommend these troubleshooting steps from the article named:
iOS: Troubleshooting Personal Hotspot
http://support.apple.com/kb/TS2756
Try disabling and reenabling Personal Hotspot from Settings > Personal Hotspot or Settings > General > Cellular > Personal Hotspot.
Install the latest version of iOS. Tap Settings > General > Software Update.
Reset network settings by tapping Settings > General > Reset > Reset Network Settings.
If none of the previous steps resolves your issue, restore the iPhone.
Cheers,
Sterling
