MBP WiFi issue after updating to 10.8.5

I have a Macbook Pro late 2011 and used OS X 10.8.4. Last week installed Windows 7 with latest BootCamp. everythings was fine! Then I updated my Mac to newer version (10.8.5).
Now WiFi just works on Windows and Mac does not find any WiFi networks.
My WiFi security is WPA2.
Any one know how do I solve this issue?
Regards,

Back up all data, then reinstall the OS. You don't need to erase the startup volume, and you won't need your backup unless something goes wrong. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
If you installed the Java runtime distributed by Apple and still need it, you'll have to reinstall it.

Anybody has remedy to this problem?

Wifi Issues after updating to Mavericks

After updating to Mavericks, the wifi on my 2011 Macbook Air started to drop a few minutes after connection. I performed wireless diagnostics, and here are the logs generated by the program.
First is the monitoring log:
# --- Monitor Test Cases
11/11/13 19:39:01.8910           No LAN Connectivity

# --- Monitor Summary
11/11/13 19:39:08.0520           LAN Connectivity Failure

Might be corrupted network preferences ...
Open the Finder. From the Finder menu bar click Go > Go to Folder
Type or copy paste the following:
/Library/Preferences/SystemConfiguration
Click Go then move all the files in the SystemConfiguration folder to the Trash.
Turn off the base station for about ten seconds then turn it back on.
See if that makes a difference.
Your Mac will generate a new SystemConfiguration folder for you.
See if that helps the Wi-Fi connection.

Ios 8.x wifi issue after update

I have been having intermittent wifi connectivity issues with my apple devices since upgrading to ios 8.x. I've subsequently updated to most recent version 8.0.2 but alas still having the issues of intermittent wifi connectivity issues (wifi works then drops without reason).
The baseline critical information is:
-Cable modem with direct internet connectivity of 20Mbps down and 2Mbps up.
-Home netgear WNDR3700v3 running latest version of firmware V1.0.0.38_1.0.31.
-Apple 5s, 5c, 5 and iPad min, iPad 2 - iphones running latest issue of IOS but ipads intentionally left back to prior versions for purpose of testing.
-Forced DNS servers to google servers 8.8.8.8 and 8.8.4.4
-Security perimeter policies in place prevent external unwarranted proxy attacks, pin hole attacks, etc. No outbound (internal to external) flows are restricted and only established flows (external to internal) are permitted.
Problem statement:
-Wifi will drop on all iphones using current version of ios causing devices to fall back to LTE or 3g.
-Reboot of netgear required to reset wireless settings for internal device usage.
-Cable modem never loses connection to internet and plugging direct into cable modem shows continued network connectivity.
-These issues never were experienced prior to updating to IOS 8.x
Question:
It would appear there is a wifi ios issue. Does anyone have any suggestions ? There are no firmware updates available for netgear given its age (2 years old).
I would prefer to not downgrade ios devices if applicable.

Worth taking a look here:
Why does iOS 8.0.2 not resolve the issue of WiFi connectivity with iOS 8 and the new iPhone 6?

MBP download issues after update.

Okay, so I did the front row, security update a week or so ago and had the problem where my screen would freeze mid booting. Called apple and they had me repair my disk permissions and rename my startup file. Everything worked fine for a while until recently. I noticed when downloading a program, it goes very slow.. Also when I open up transmission or tomato torren and try to open a torrent file, it freezes and I have to force quit the program. I have no idea what happened to my MBP but I am getting really sick of all the problems I'm getting. It also wont let me connect to my schools wireless internet anymore. Anybody know what I could do to relieve these issues? Thanks.

I am sure that there are other users that have had problems since updating the iOS. Have you totally reset the iPad up as a new device - not from a backup - and you are still having the issues?
If you have done so, have you tried closing all apps? Then when you start using apps - if the iPad works OK up until you launch a certain app - it may be that particular app is cursing the issue. And BTW, have you updated all of your apps since you updated the iOS?
Closing all apps .....
Go to the home screen first by tapping the home button. Quit/close open apps by double tapping the home button and the task bar will appear with all of you recent/open apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner to close the apps. Restart the iPad. Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.

Wifi issues after update to ios4

Hi all,
Since updating to os4, I've been having problems with the wifi on my iphone.
If will connect to my home network fine, but it refuses to use the wifi connection. Checking everything in settings, it all seems fine, it says connected with good strength etc.
But it just doesnt use wifi.
Oddly, the only time the wifi symbol comes up, is in call, which im finding a bit odd. But as soon as I end the call, the wifi symbol disapears and goes back to gprs.
I've rebooted the phone several times, got it to forget wireless networks and set it all up again, reset the network setting, and recently restored and update to os 4.0.2 with no luck.
Anyone got any ideas?

Any problems connecting to any other wi-fi network?
If the same with any other wi-fi network and no change after resetting network settings on your iPhone and after restoring your iPhone with iTunes as a new iPhone or not from your iPhone's backup, more than likely your iPhone has a hardware problem.
You can contact AppleCare or make an appointment at an Apple store if there is one nearby.

WIFI problem after update 2.2

Like many users in this forum I also have problems with the wifi connection after updating to 2.2.
I have the first gen iphone, ever functioned without major problems, but after update 2.2. I found out that my iphone looses the wifi connection after some minutes of being turned off and turned on again. Sometimes the wifi is established but most of the times I have to go to the settings and there try to connect to wifi again and again.
Sometimes I get wifi connection after 2 attempts, most of the times it takes up to 8 tries to have wifi again. I restored my phone three times now, hoping this problem would be solved, but in vain.
I also called the Apple support-first I was told to delete the 2.2. software from my itunes folder and then to restore again and let itunes download 2.2 software again - no improvement! At my next call with the Apple-Iphone support, the agent told me that I should delete my router settings, restore the iphone software- no new strategy at all - and that the problem with the wifi after 2.2. is not a well known issue by Apple; I told the agent to google this topic to see that this is a very common problem concerning hundreds of even thousands of users after the update 2.2. At the end of the call I was offered to send the iphone for a repair, which in my opinion is the common solution for support centers if the don´t have any solutions left. I refused to send my iphone to a "useless" repair, because it´s so obvious that the problem is the 2.2. update! I encourage all of you to call the support-hotline and make pressure to get Apple to release a quick update to fix this annoying problem! Happy New Year to all of you!

Thanks for your advice; I´ve resetted the networks setting twice; a little improvement came with this (the wifi-connection now sometimes establishes faster); but still..after having turned on my phone after some minutes paused there´s only "edge" activated. Seems I´ll have to wait for update 2.3 ?

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.

Syncing issues after updating to 10.3.1.55

After upgrading to itunes 10.3.1.55, today, it no longer recognizes my iPhone 4. I plug it in, the iPhone makes its normal syncing noice. I get a prompt, like always about it recognizing the camera and how i want to handle it. I cancel it, as usual, and then it never shows up in iTunes. I close itunes, connect my phone and it does not start itunes as it normally should. No error messages, just no response. Can anyone help with ideas?

I had the same issue, after updating to 10.3.1.55 it would error out saying something along the lines of not being able to read the catalog or something. I think the error even states do a restore to fix it. Last night that is what I did, clicked restore and then had it transfer all my items back. I'm glad I had just synced my phone prior to the update so the restore was really current.

Safari, App Store Issues after updating to 10.7.2

I have been running my imac that came preinstalled with Lion
I am having this wierd issue after updating to 10.7.2 recently
When i run Safari, App Store, Itunes, i can see its loading..
but after 2 hours its still loading.
It just seems to be stuck and its not the Beach ball.. So i dont think it hanged
Its not a network issue as well, since i am typing this on Firefox, which is running perfectly
What could be the reason?

I'm having the same issue on my iMac. I've also noticed the rear of the left side is getting a lot hotter than normal.
I downloaded (from: http://support.apple.com/kb/DL1459) the update again and reinstalled it. But nothing's changed. Is there anything else I can try?

Issues after updating iPhone3GS to iOS5 on TIM cellular data network (Italy)

Hi everyone
I have issues after updating iPhone3GS to iOS5 on TIM cellular data network.
After installing iOS5 I had to switch from apn ibox.tim.it to wap.tim.it
Since then the phone is unusable for any internet activity that is barely "data demanding" (e.g facebook app take literaly hours to update), everyting requires way to much time... the iPhone is not an iPhone anymore... it's worse than my blackberry with just GPRS on it.
TIM technical support suggested me to switch back on apn ibox.tim.it, but then I would not be able to use internet tethering anymore (they say because of Apple iOS5) ... to bad I need internet tethering for work.
I am seriously thinking to switch ISP or phone.
Anyone did experience same problem / found a solution?

Hi Raia.D,
Welcome to the Support Communities!
The first thing I would suggest is to restart your iPhone. Then tap the Settings app, and you should see Cellular listed on the main settings screen. You should see Airplane Mode, Wi-Fi, Bluetooth, and then Cellular.
Here are some additional troubleshooting steps to try:

LEAP WIFI problem after updated to 4.2.2

I've just upgraded my tablet to 4.2.2.
Now I can't connect to my company's network which uses password LEAP. Major problem for me.
Seems this is a common problem across a number of Android platforms.
Does anyone know how to resolve on the Tab Z (not rooted). ?

We are looking into this (see http://talk.sonymobile.com/t5/Xperia-Z-ZL-ZR/XPERIA-Z-LEAP-WIFI-problem-after-updated-to-4-2-2/m-p/3...) but at the moment i have no solution. This seems to be a general problem with Android 4.2.2 from what i've been able to find.
