Unable to reconnect to wireless network after closing lid on macbook pro

After installing recent software updates, I am unable to reconnect to my wireless network when I close the lid on my macbook. It says that it is "connected", but I can't access any website, check e-mail or ping any external server.
I've never had a problem before, but now that I've installed software updates in the past few weeks I noticed the problem.
Anyone have any ideas?
MacBook Pro (Intel) Mac OS X (10.4.9)

which ultimately means apple didn't do enough testing before releasing the last patch
This is not always, and may not be, the case. What many don't realise is that many 3rd party developers stray from the 802.11 series specifications in an attampt to boost speed and get one up on their competitors. For instance D-Link, amongst others, use a short preamble setting by default in some of their routers to improve performance. However, this is non-standard and when it comes across wireless network adapters that don't support this then you have problems. They assume that their network adapters are being used for "maximum speed and compatibility". Whether Apple should or should not support a short preamble is another subject altogether.
However, I do agree with you in that Apple should put more work into their Airport software.

Airport Express (1st generation) does not reconnect to wireless network after router is cycled on/off

Operating System: os x 10.9.1
Airport Utility 6.3.2
Airport Express 802.11n (1st generation)
Linkus router: Model WRT310Nv2, Firmware Version 2.0.01
Motorola Cable Modem: Model 2210-02, Firmware 7.7.3r5
The Airport Express (AE) is setup to join my wireless network using Airport Utility. A printer is connected to the AE with a USB cable. After the setup the AE light is green and the printer can be accessed over the wireless network.
The problem starts if the router is cycled off/on. Now the AE will not rejoin the wireless network and there is a non-flashing amber light. If the power to the AE is cycled off/on the AE reconnects to the wireless network.
This is about as handy as a screen door on a submarine.
Is it possible to see the setting of the AE the same way the modem and router settings can be accessed? Can this issue be fixed?

If they send you a replacement printer it will have ink tanks with it. You can store the ink tanks from your current printer and use them later on you "new" printer if you wish. Store them nozzle-up so they do not leak.

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

Unable to find wireless network on Photosmart C4780 on MacBook Pro running OS X 10.10.3

I have been successfully using a Photosmart C4780 on my wireless network for a long time. I had internet issues and the network name was changed. Now I can't print wirelessly. Tried reinstalling the software, but the program quits just before set-up.
Help!!

Hey there @physiocan!
Thank you for posting on the HP Forums!
I should be able to provide some suggestions that may get your Photosmart C4780 reconnected to your wireless network. Due to the age of the printer there is no full feature software and driver developed for Mac 10.10. Your printer requires the HP full feature software to setup the wireless through the USB cable. Once the Wi-Fi is setup then the USB cable can be removed. To reconfigure your printer to the new network name you will require a computer running the Windows operating system or a Mac with version 10.7 or lower.
Please post back and let me know! You will only require another computer for the Wi-Fi setup. Once the wireless is setup then you should be able to add it to your Mac 10.10 using the Apple Airprint drivers built into the Mac operating system.
Thanks again for posting on the HP Forums!

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
iOS: Recommended settings for Wi-Fi routers and access points http://support.apple.com/kb/HT4199
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.

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.

MacBook can't see my home wireless network after upgrade to OSX 10.8.5

After upgrading to OSX 10.8.5, my MacBook does not detect any wireless nertworks. My iPad and iPhone work fine, my router has been rebooted, WiFi is turned on, and the ethernet connection is how I am writing this message to you via broadband. There are a half dozen wireless networks in range (according to my iPhone) but the MacBook cannot find the router I am sitting next to. Any ideas on how to correct this issue?

It appears an SMC reset was required:

Here is your other post: MacBook can't see my home wireless network after upgrade to OSX 10.8.5
If you reply to it and marked it "solved", perhaps with a link to that post (copy and paste it, or just say you performed the SMC reset) it will help others find a solution. Thanks!

This AirPort base station was unable to extend the wireless network.

I have an AirPort Extreme in the lounge connected to BT infinity.
I also have an airport express in the kitchen connected to a stereo system.
I have had this set up for around 12 months.
The airport express will not extend the wireless network.
I reset it, restart, factory reset etc and it will work fine for around 3 days, then I get the same error message saying
This AirPort base station was unable to extend the wireless network. Make sure the wireless network you’re trying to extend was set up and is working correctly, that you entered a matching wireless network password into this device, and that this device is in range of the wireless network.
The express is situated easily within range of the extreme. And the airplay between those two, my iMac and two apple tv's works pretty much as it should.
Can someone please shed some light on this?
Maybe I have it in a wrong setting or summut....

I am also experiencing a recent failure in my Airport devices no longer extending my wireless network.
My Aiport Express and second Airport Extreme were extending my wireless network for more than a year
The only change that has taken place lately is that the firmware for both devices was upgraded to 7.6.4, however the upgrade was only in response to trying to resolve this problem. Needless to say, the firmware upgrade did not resolve anything.
If I didn't know better, I'd have thought I wrote the above.
I have a TC from a few years ago (last one before the tower, I think), plus the older AEBS that it replaced extending the network, plus a 1-year-old Express also extending. I had upgraded them all to 7.6.3/4 when it came out, but reverted them all to 7.6.1 when everything went crapways (others having the same issues of the LAN regularly croaking), and didn't bother upgrading again since.
Today I just tried 7.6.4 on all of them, and it seemed OK at first with green lights all around in Airport Utility. Then I made one change, which was to enable 5Ghz on the main AEBS/TC only (the express doesn't need it, and the older AEBS can't do it).
The latter two started flasing amber and giving the "unable to extend wireless network" error message.
So I'm wondering if you are similarly using 5Ghz?

HT204409 I am trying to log onto my wireless connection but it keeps telling me I'm unable to locate any wireless network. I know there are several networks nearby. Is this a problem with my phone or my router?

I am trying to log onto my wireless connection but it keeps telling me I'm unable to locate any wireless network. I know there are several networks nearby. Is this a problem with my phone or my router?

I found a solution that has worked on both iPhone 4's I have that have had the same issues, and also including not being able to download updates in the App store.
Go to Settings > WiFi and turn it OFF.
Next go to General > Cellular > Cellular Data and turn it OFF
Next go back to Settings > WiFi and turn it ON, (wait a few seconds for it to sync with your network)
Finally go back to General > Cellular > Cellular Data and turn it ON.
I had the same issues on both my wife's phone, and my own, and it fixed it immediately without changing any proxy settings or reboots, (which I did try on my phone and did not work, but did not try on my wife's phone)
Hope this helps!

Out of the blue, my ITouch is unable to access my wireless network ONLY when my PC has been turned on (PC is connected via Ethernet cable, and has no wireless capability as far as I know). What gives? It works fine when the PC is off.

Does the iOS device connect to other networks?
Does the iOS device see the network?
Any error messages?
Do other devices now connect?
Did the iOS device connect before?
Try the following to rule out a software problem:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Power off and then back on your router
.- Reset network settings: Settings>General>Reset>Reset Network Settings
- iOS: Troubleshooting Wi-Fi networks and connections
- Wi-Fi: Unable to connect to an 802.11n Wi-Fi network
I suspect a problem with your router. Try changing the security. First use no security as a test.
- iOS: Recommended settings for Wi-Fi routers and access points
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem and it does not connect to any networks make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

Unable to connect Wi-Fi network after ISO 6 update

unable to connect Wi-Fi network after ISO 6 update. I'm not impressed.

I updated to ISO 6 on my Daughters Iphone 4S, my Iphone 4, and I have now received my new Iphone 5 yesterday and now all 3 of them have wi-fi issues. I know its not my wi-fi because My Daughters Ipad 2 and my Wife's Iphone 4 is still on 5.11 and the wi-fi works fine. I cant understand why apple have not been saying what's going on and when they will fix it. I have tried everyone's suggestions on this forum and the Internet. Still no luck.

Welcome to the Apple community.
Do you actually see a weak signal shown on the Apple TV when it is connected to your network. The problem may not be a weak signal, it may be interference from other networks or electrical devices.

After not using my macbook pro for 10 days, my wireless mouse no longer works. (I had turned the computer off). I've gone in to mouse preferences but the computer won't recoginize the mouse. It worked fine before the trip. Batteries were changed.

After not using my macbook pro for 10 days, my wireless mouse no longer works. I had the computer turned off. I've changed the batteries, gone to universal preferences, mouse preferences but the computer won't recognize the mouse. Any suggestions?

Got it. Thanks. I deleted the mouse (not an apple, but a logitech which has worked fine for me) and then re-discovered it and it's working. Appreciate the advice.

I'm unable to do a clean install of Firefox 6 on Macbook Pro OSX 10.6.8.

I'm unable to do a clean install of Firefox 6 on Macbook Pro OSX 10.6.8. After trashing the firefox.app from the Applications folder and trashing a related file in the Library folder and then reinstalling, all of my previously opened windows and tabs reappear. And the history and bookmarks are populated too! Then, the computer freezes up so that I must reboot. Because these windows automatically open and the history and bookmarks are populated with my old history and bookmarks, I believe this is not a clean install. Please help.

Click on the blue Internet Recovery in nbar's post. That is a link to what computers can run Internet Recovery.
Do a backup, preferable 2 separate ones on 2 drives. Boot to the Recovery Volume (command - R on a restart or hold down the option/alt key during a restart and select Recovery Volume). Run Disk Utility Verify/Repair and Repair Permissions until you get no errors. Reformat the drive using Disk Utility/Erase Mac OS Extended (Journaled), then click the Option button and select GUID. Then re-install the OS.
