HT5052 Why does my computer not download ios5 completely and says it has timed out and could not download? Why can I not get my ipad to wifi it was fine but now all my emails have disappeared and also I cannot connect to wifi?

Some problems occurs when your Internet security program was set
to trust the previous version of Firefox, but no longer recognizes your
updated version as trusted. Now how to fix the problem: To allow
Firefox to connect to the Internet again;
* Make sure your Internet security software is up-to-date (i.e. you are running the latest version)
* Remove Firefox from your program's list of trusted or recognized programs, then add it back. For detailed instructions, see

Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Change the channel on your wireless router. 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.

Hey NicolasZen,
Thanks for the question and welcome to the Apple Support Communities. I understand that you are experiencing issues with “No Service” or “Searching” on your iPhone. The following resource provides some great troubleshooting steps that you may wish to try:
iPhone: Troubleshooting No Service
http://support.apple.com/kb/TS4429
Your iPhone may have one of these symptoms:
- iPhone displays "No Service" or "Searching" in an area of good coverage
- iPhone doesn't regain service when returning to an area of coverage
Resolution
If you encounter either of the above symptoms on your iPhone, follow these steps to attempt to resolve the issue. Test after each step.
1. Toggle airplane mode: Tap Settings > Enable Airplane Mode, wait five seconds, then turn off airplane mode.
2. Turn iPhone off and then on again.
3. Remove the SIM card and verify that it's a valid, carrier-manufactured SIM. Also verify that it isn't damaged, worn, or modified. Then reinsert it.
4. Check for a carrier-settings update. Connect to a Wi-Fi network. Then tap Settings > General > About. If an update is available, iOS will ask you if you want to install it. If Wi-Fi isn't available, connect your device to iTunes.
5. Update your iPhone to the latest version of iOS.
6. Reset network settings by tapping Settings > General > Reset > Reset Network Settings. This will reset all network settings, including Bluetooth pairing records, Wi-Fi passwords, VPN, and APN settings.
7. Restore the iPhone.
Thanks,
Matt M.

I am extending my airport extreme by adding an airport express. I had no problem setting it up and got green lights but now I cannot get on either because it says it is a self assigned IP?

Does this mean that you are connecting the AirPort Express to the AirPort Extreme using a wired Ethernet connection....or....are you connecting the AirPort Express to the AirPort Extreme wirelessly?
but now I cannot get on either because it is a self assigned IP?
I suggest that you first concentrate on getting the AirPort Extreme working correctly. Power off the modem and both the Extreme and Express, wait a few minutes, then power up the modem and let it run a few minutes. Then, power up the AirPort Extreme and check the network for proper operation. Leave the AirPort Express off for now. Report on your results.
We need to know what operating system you are using on your Mac or PC in order to provide more troubleshooting help.
If you have a Mac and do not know what operating system you are using, click the Apple icon in the upper left corner of the screen, then click About This Mac. Post back with the OS X version number that you see there.

Problems connecting to home WiFi

Recently my MacBook Air simply will not connect to my home WiFi automatically. I have to wait for it to search for all WiFi, and then manually select my home WiFi. Sometimes even then it fails, and I have to manually select the WiFi again. So, it might take several minutes after wake from sleep to connect to WiFi. How can I solve this problem? Here are some other observations
- My MacBook Air seems to have no problem automatically connecting to other WiFis I use regularly.
- My iPhone and iPad and my wife's PC has no problem connecting to the home WiFi.
- The MacBook Air used to connect fine. It might have changed after some software update.
- Seemingly the MacBook Air connects fine to the home WiFi during sleep (power nap). But once it wakes up, it will not connect.
- The WiFi signal is very strong once connected (the router is just a few meters from the Air).

The latest update solved my issue too. But only for a few days.
It's not just inconvenient - it's costly. I recently spent hours instead of minutes trying to book airline tickets and ended up paying extra because "Your session has timed out" while my Macbook Air - with 10.9.4 - kept losing its connection. I log back in and find prices have gone up.
Other household items - an iPad Air and iPhone and my wife's Samsung - have no such problems, so it is clearly this 6 month old Mac Air that is the problem. Or, perhaps more accurately, the OSX is the culprit, as I was having similar problems with my Macbook Pro before I upgraded to the Air.
I have posted a question about wifi issues here, and searched forums, and tried all of the tricks that have been suggested. Wasted hours following tips that didn't work. Sometimes I get a temporary reprieve - as happened when I turned Bluetooth off. Other times it makes no difference.
To illustrate how much the issue has frustrated me - I have contemplated jumping ship, especially as my friends with Lenovos and Sonys gloat at my problems! If I do jump ship with my next notebook, it will be the only time since my first computer (a Mac) in 1992 that I would have purchased anything else. But something has to give. I can't live with this constant disruption of wifi.

My macbook air is not getting internet connection through our home wifi It was working fine yesterday until I took the Air out of the house and used it on another wifi connection.

My macbook air is not getting internet connection through our home wifi. It was working fine yesterday until I took the Air out of the house and used it on another wifi connection. One question is how to delete some of the networks that I don't use. Would too many networks cause the internet connection to fail?
Thanks.

Would too many networks cause the internet connection to fail?
It shouldn't but sometimes deleting the list of networks actually does solve the problem you are describing. Have you turned WiFi off and then back on on the computer?

HT3964 connected new external monitor to macbook pro, was working but now have no power, black screen in laptop. monitor purchased with advice from tech and set up also. Worked fine for an hour and then quit

Have just connected a viewsonic external monitor to macbook pro 10.6.8, had everything up and running fine for about an hour then the macbook quit. No power (ws running off power source) Have I killed my macbook? Help!

Aha, all is good.
I went to Library/ColorSync/Profiles/Displays
and to home/Library/ColorSync/Profiles/Displays
and deleted all SyncMaster.icc files. I did leave behind one SyncMaster file in the home/../Displays which had an old date and I new was ok.
Rebooted, plugged in SyncMaster, and a new icc file was automatically created in the /Library/../Displays folder.
My display works normally, now.

Unity Connection 8.5.1 Backup was working before now it won't setup?

My Backups for my Unity Connection 8.5.1 have stopped working. I had set it up when I first installed both the CUCM and Unity Connection 8.5.1, then I had to make a change in the network addresses on the backup server. I was able to restart the backups on the CUCM no problem, however the Unity Connection server wont allow me to setup a new instance of the Backup Server. Before I even get started setting up with the device it says at the bottom of the screen :
The Backup Device which is associated with 1 or more schedule(s) cannot be deleted.
It will allow me to go through the entire process of setting things up but will fail every time. I have run traces on the network, and it never attempts to touch the SFTP server, Can someone shed some light on this?
Thanks, Mark

Hi Mark,
This particular error means that the Schedule has to be deleted before making changes to the backup device. You have to delete the schedule before trying to make IP address change on the existing backup device, or you could create a new backup device and schedule altogether.

My home button has stopped working, and now i cant get siri to stop popping up

all the suddon one day my home button stopped working. its never been dropped or gotten wet. i just got the phone less than a month ago.
now siri pops up out of nowhere and when im doing something, like on an app, it will glitch and go to the home screen. its almost like the home button is stuck. its getting to the point where i cant do anything with it. i have already restored the phone multiple times. i have apple care. do you think that apple would replace my iphone 4s?

Apple might. I'm not a genius on Apple Care though.
But if you go to a Genius bar, the guys there might be able to fix it for you.
In the meantime, try pressing the home button really hard. It may pop up.
This is the best I can do.

E61 Problem connection to Home wifi LAN

My E61 worked fine until I changed my router to a Netgear DG834GT. It uses 802-11 b & g. and I have the latest firmware on the phone. The router has built in wifi which works well on my laptop, it connects to the access point without any problems at all.
I am not unable to connect with my phone. I can 'see' the WLAN SSID in Available Networks - it's set to Infrastructure. I has a WEP key set.
When I try to connect using that access point e.g. to update 'WorldMate Weather' I getthe error message "Connection error - check settings"
If I try to collect my emails or surf the 'Net I get: "WLAN - Unable to connect. WLAN network not found!"
Any help would be appreciated.

Hi,
you could test the following if it helps:
1) disable power save feature from the phone
2) set access point to open authentication and no encryption
3) scan for WLAN networks and start web browsing using the found access point
Any difference? Don't forget to restore the security settings afterwards.

Voice control blue screen appears while I play musice and either stops song, switches to another. Hitting cancel or pressing home key at first worked but now it is not. How to stop this?

Ok. So I can be doing just about anything while my ipod is playing and then this voice control screen appears wih the blue screen. I can shut it down and then turn it on after a while but that may or may not stop the problem. Even if I have it locked this happens.
Even when I hit the home key or slide cancel, this keeps happening. It is very annoying.
How do I stop this?

Have you tried the standard fixes:
- Reset:
Reset iPod touch: Press and hold the On/Off Sleep/Wake button and the Home
button at the same time for at least ten seconds, until the Apple logo appears.
- Restore from backup
- Restore to factory defaults/new iPod
If still a problem you likely have a hardware porblem and an appointment at the Genius Bar of an Apple store is in order.

I am having problems connecting to home wifi. It was working, but now all I get is a blank white screen. I re-booted with no success.
