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?

Hi i upgrade from lion to mountain lion to day on my mini mac,Since the upgrade i am getting no sound through my HDMI cable which was working fine on lion Checked the midi audio settings and system preferences to out on HDMi nothing no sound whats so ever

Hi i upgraded from lion to mountain lion to day on my mini mac,Since the upgrade i am no longer getting sound through my HDMI cable which was working fine on lion Checked the midi audio settings and system preferences to out on HDMi nothing no sound whats so ever.Any one any ideas?
I use a samsung TV for my monitor via HDMI.Tried all the system Audi setting nothing .Head phone and internal speakers are fine.

Similar issue; Audio was working fine on Lion, now not on Mountain Lion. Have a Macbook Pro early 2011 with AMD Radeon HD 6750M, connected by thunderbolt through a Lacie LBD to a mini-displayport to HDMI adapter (n.b. same problem when not going through the LBD) to a Pioneer VSX 521 AV receiver. For me when I go into audio Midi settings all the volume sliders for the displayport device are greyed out and at zero. But when I click 'configure speakers', it's able to send out the test signals to each speaker. Part of the problem could be that I'm not getting the option to put out 6channel sound, only 2 or 8 channel. Since my system is Dolby 5.1, and I only have 6 speakers, I would have expected the 6ch option to be available. But I imagine there's more to it than that. Elsewhere someone has suggested playing with Remote Interactive over HD on an Onkyo device; I'll see if there's something similar on the Pioneer that can be changed. Any other suggestions welcome.

Problem with not getting Internet Connect on AirPort Express

Problem with not getting Internet Connect on AirPort Express (version7.6.4). Error says cannot get valid IP address. Have reset Siemens SpeedStream 4100 several time, even with tech support from the big "A" DSL provider. Plug MacBook Pro directly into modem and works fine. Unplugged AirPort, even reset it, still no luck. A bad Express?? or am not looking in the right place to make connection. Was working fine up until Sunday.

Connect the AirPort Express (AX) to the cable modem via Ethernet cable.
In configuring the AX using AirPort Utility:
Under Internet, set the connection to be Ethernet using DHCP.
Under Connection Sharing, set it to distribute a range of IP addresses.
Under AirPort>Wireless, set the Wireless Mode to Create a wireless network, and fill in the remaining settings in the same window. Until you get it working, you might want to set Wireless Security to None.

My Ipad will not unlock. When I slide to unlock it speaks 'unlock key', if I touch the date it 'speaks the date', but I cannot get into the pad. Was working fine yesterday, any suggestions would be appreciated. Lisa

My Ipad will not unlock. When I 'slide to unlock it speaks 'unlock key', if I touch the date it 'speaks the date', when I turn it on is 'speaks the time', but I cannot get into this ipad at all. It was working correctly yesterday, any idea's would be appreciated.

Your iPad is likely stuck in in VoiceOver mode. Try triple-clicking the home button or connecting your iPad to iTunes on your computer. You can disable VoiceOver in iTunes from the iPad's summary page by scrolling down to the Options box and clicking on Configure Accessibility.
Good luck!

Use the trackpad to scroll, thats what it was designed for. The scroll bars automatically disappear when not being used and will appear if you scroll up or down using the trackpad.
This is a user-to-user forum and most people will post on here if they have problems. You very rarely get people posting to say there update went smooth. The fact is the vast majority of Mountain Lion users will not be experiencing any major problems with the OS, or maybe with apps which are not compatible, but thats hardly Apple's fault if developers don't update their apps.

TS1398 iPad was working fine yesterday -day 3 being in London - but is not picking up a carrier today. What can I do???

iPad was working fine yesterday - day 3 being in London - but is not picking up carrier today - what can be done?

Are you referring to wifi or cellular?
 Cheers, Tom

Note 3 won't answer a call by using the "answer" voice command. Other voice commands work fine (ie 'volume up') and speech to text works fine. Tried it in the car and in a quiet room at home. What am I missing?

HT1338 My macbook pro is not recognising or connecting to the personal internet hotspot on my Iphone 4. How do I rectify. Was working fine yesterday.

Since yesterday my macbook wont accept or connect to my personal hotspot on my I phone 4s. Any suggestions fellow applemeisters?

Problem resolved
I was unable to use iPhone 4 ios 6.o.1 as a WIFI Verizon cellular hotspot to give my with my Macbook PRO OSX 10.6.8 internet access
In the past I was able to do so but this function quit working several months ago. I blamed it on either defective hardware or IOS 6 upgrades.
My iphone showed an active hotspot and connection but I was not showing a connection on my Macbook. I was getting an error on my Macbook saying bluetooth was not active on the device.
As a result I was not able to tether my Macbook to my iPhone hotspot through bluetooth or via USB
After MANY MANY hours researching I found an idea for the solution in the website below by Girl.luvzer.Mac
http://chimac.net/2010/10/21/your-connection-failed-because-the-communication-de vice-is-unavailable-make-sure-its-connected-to-your-computer-and-try-reconnectin g/
My instructions are below:
Go to Macbook System Preferences>Network . At the top of this window, it probably will say Location:Automatic. Click that drop-down box and choose “Edit Locations”. Click on the +, and create and select a new location. You do not need to name the location you create.
This was the key for me to get my iPhone hotspot bluetooth and tethering working with my Macbook
Some other notes:
Your cellphone provider needs to enable hotspot capability on your cellphone service
Your iPhone settings will need to have both bluetooth and cellular hotspot turned on
You will have to pair your iPhone and Macbook
Go to ...Settings/ Network/Bluetooth
   Click the ON and Discoverable boxes
   If your iphone is already shown in the box on the left press the - button to remove it
   Click sharing setup to pair your Macbook with your iPhone
In your Macbook ...Settings / Network
Turn off Airport
   Select Bluetooth Pan and use the connect button to connect to your iPhone
   It will take a moment for the connection to complete
Once you have done that your iPhone should provide your Macbook a wired USB or a Bluetooth hotspot!!!
Good luck, I hope this works for you as well
This was submitted via my Macbook through my newly fixed iPhone hotspot ;-)

IPad connects to network, but not internet, and it was working fine yesterday

So yesterday it was working fine, conecting to the internet and the router, then all of a sudden 'Safari cannot load the page because it is not connected to the internet', it was the same for all the apps that needed internet.
My 4th generation iPod touch connects fine and so do other wireless devices on my network, what went wrong and how can I get my internet back!??
I have tried resetting the connectivity settings, resetting the router, adding the MAC address of the iPad to my routers 'Safe List' (which it wasnt on before it stopped working), and tried turning on and off the iPad.
So what can be done to fix this?
Thanks in advance

Ok. So after tweaking my IP settings no luck.
Then I set up a Static route then put it into the settings on the ipad under 'static' and finally it works!
A lot of hassle for such an annoying problem but I still have no idea why it didn't connect in the first place!?
You found a work-around. Can't argue with success but you have not solved your problem. You should continue trying to get it to work via dhcp and dynamic addressing.

My MBP 7,1 wifi connection suddenly stopped working. It was working fine before until the battery emptied. I turned it on but it froze so I tried to reset it. Then, after that it no longer detect any wifi signal in any areas I go.

Hi Everyone. My MBP 7,1 didn't have any wifi issues not until 2 weeks ago. The laptop's battery got empty and when I tried to turned it on, the computer just froze. So I tried to reset it. However, I noticed that the wifi or airport can no longer detect any wifi signal. There were instances that it wouldn't turn on when I shut it off but now, it seems okey. I tried the zapping of PRAM and deleting all the things needed as I saw in different threads but it still not working. The ethernet works fine but I still need the wifi. Its been 2 weeks already. I don't have an Apple Store near me coz I am in southern part of Philippines. Can someone shed light on this? Thank you so much.

Hi!! To add more to the issue, the other day, my airport card is nowhere to be found. It now says no airport card installed which is really crazy. I also noticed that my MBP freezes during start up and I had to zap the PRAM so it would open up. Anyone there who experienced the same thing? I'd really appreciate your suggestions. Thanks!

Firefox was working fine on myWindows Vista. The internet was down. When sevice returned. Firefox would not connect. Internet Explorer works. E-mail works. Television signal works. It is enable on the fire wall. However, Firefox won't connect.

The internet is working. I downloaded Firefox again. It will not connect.

I have unistalled, and reinstalled Firefox three times. I have unplugged the modem, rebooted the computer, made an exception in the firewall, can get e-mail and use other browsers. There is some button I'm not pushing somewhere. Can't anyone working at Firefox answer this question? I'm ready to give it up all together. Thanks.

My guests does not get internet access through my guest network

I have created a guest network on my time machine. The problem is that my guests don´t get internet access when they choose the network and type the password. I don´t understand why this is happening? My ordinary network is fully functional.

If you are using 7.6.3 firmware on the TC, the guest network does not actually work in bridge mode.. it looks like it does.. but nope, it doesn't.
Make sure the TC is the main router in the network.

I have a new Apple TV, I plugged it in yesterday and it worked fine. I then did the update and went to bed. Today I can't get the Apple TV to turn on again! HELP

I have a new Apple TV, I plugged it in last night and it worked fine, I then, I was mirroring with my iPad and everything. It then prompted me to to the update so I hit update and went to bed. Today I can't turn the Apple TV on!
It just says no signal on my tv.
I've tried pressing menu and down arrow for 6 seconds, an apple appears on my tv screen but then it goes back to saying no signal!
Is it broken?

Check these troubleshooting steps:
http://support.apple.com/kb/HT1551?viewlocale=en_US&locale=en_US
Specifically I wonder if the AppleTV may be trying to connect with an unsupported resolution giving a black screen. Try cycling display resolutions using these remote commands in step 6:
If your TV screen appears fuzzy or black (you see no video)
Make sure the television you are using supports the Apple TV resolution requirements. Please see the Apple TV technical specifications.
When you connect power, check to make sure the LED turns on. If the LED is not on, then verify with a known good power outlet or connect something else to the outlet you're using for Apple TV and make sure it works (such as a lamp or clock).
Make sure you're using the correct video cables and that they are connected firmly to Apple TV and to your TV.
Connect the HDMI cable directly into the Apple TV and your television, remove any third party devices or adapters.
Make sure the input setting you've selected on your TV matches the input you have your video cables connected to. See the documentation that came with your TV for more information.
Change the Apple TV resolution by pressing and holding the Menu and Up button for six seconds. The Apple TV will automatically cycle to the next resolution at approximately 20 second intervals. Pressing the Select button will immediately cycle to the next resolution.
If you are connected via HDMI, try unplugging and replugging your HDMI cable.
If HDMI isn't working on an Apple TV (1st generation), try component cables instead (and disconnect the HDMI cable temporarily). Read more about HDMI vs component video.

I am having problems with my Mac Book Pro Retina locking up after updating from Lion to Maverick. I was having no trouble until I did the upgrade, and now it is locking up, freezing after about 5 minutes, and getting hot. Any suggestions?

A while back I had an upgrade available to me. I had Lion when I bought this Pro. The upgrade is Maverick. After downloading and installing the upgrade, my computer started freezing while doing anything. I might not get this completely written before it freezes. The keyboard is getting hot, and I have to use the power button to turn it off. After it has sat for at least 10 minutes, I can turn it back on. I might be able to do some work for 5 minutes, or up to 30 minutes before it freezes again. Some of my programs are not working, either.
I would appreciate any suggestions anyone might have, or even go back to Lion, if I can figure out how to.
Thanks.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.
