All of a sudden, no signal

I've had the Airport Extreme for at least five years and it's worked perfectly, All of a sudden, it drops off in the middle of reading mail messages. Signal strength is down to zero, but Internet Connect still shows the Airport as connected -- just nothing coming in.
Lights still flashing like normal on the unit, did the usual -- unplug and plug back in and then pushing the reset button. Still no change -- lights flashing, but no signal strength, even on the iBook sitting right next to it. The iBook works with the Ethernet plugged in, so it's not a computer or cable modem problem.
Do I need a new Airport?
Tom

Two possibilities.
Faulty wireless RF radio module on the Mac, or faulty RF radio on the extreme base station.
However, even your 2nd working iBook also get zero signal. That's probably a good indication that the base station is gone.
I'm afraid, you may need a new base station.

Last night my iphone screen all of a sudden was solid blue and now it is black. I tried turning it on and off. Still nothing appeared on the screen. I put it on the charger and this morning it is totally black. However, when I hit the on and off button, I did hear the text message signal go off. When I turned the volume on and off a big white bell flashed. In the last week, there were some other display problems such as the screen blowing up large. The only way to fix it was to turn off the phone and then turn it back on.
What does all of this mean? It seems like I've had these problems since the iphone 4 upgrade.

just do reset, press home button and power butoon for a while untill you can see apple
gud luck

No signal on phone all of a sudden

My phone is all of a sudden searching for a signal but my wifi is working. My signal will once in a while come back but then when i go to send a message, it goes back to searching for service. I tried turning my phone on and off several times, checked my settings... How do I fix this?

i am having the same problem here the only sim that gets signal is t-mobile try that sim and see if that works other than that none of the other sims work it says no service
i recommend you take it to apple store if you have warranty on it but first you will need to book an appointment for one of the apple geniuses to look at the problem and if its not fixable then they will arrange to give you a replacement phone

So my iPhone 4S started draining battery after recent update, battery got changed and it worked perfect for 3 days, all of a sudden the phone won't stay on unless connected to mains... Cannot receive any signal "searching" constantly. HELP

So my iPhone 4S started draining battery after recent update, battery got changed and it worked perfect for 3 days, all of a sudden the phone shut down and now won't stay on unless connected to mains... Claims its at 100% battery but thats impossible as it was at 30% before it shut down randomly.
Cannot receive any signal "searching" constantly.
Turns off as soon as removed from usb ... wont stay on connected to laptop!
HELP!

The iPhone includes a one year warranty. If an Apple store is not nearby, you can call AppleCare and handle an exchange under warranty over the phone. The exchange will be shipped to your door - someone must sign for the delivery so if no one will be at home, have it delivered where you work. You use the same box to return the existing iPhone back to Apple. Return shipping label and tape to reveal the box incuded - call the carrier with number incuded when the box is ready to be picked up. AppleCare will request a credit card in the event the existing iPhone is not returned within 10 days after the exchange under warranty is received.
Hardware can fail - it happens, which is why there is a one year warranty.

All of a sudden I have to be Very close to a modem to recieve wifi. Tried resetting network settings, no joy. This is true for all modems everywhere. Any ideas?

Your home wifi may possibly be having issues. Call the company that does your wifi and they should send someone out to service it.

IPhone 5S: does anybody has this problem. During a successful voice call all of a sudden people can't hear me while I can hear them

iPhone 5S: does anybody has this problem. During a successful voice call all of a sudden people can't hear me while I can hear them. Signal is strong and call quality (me hearing the other) is still very good but it looks as if I’m going on mute while I’m not muting my iPhone. When dropping the call and re-dialing it works fine again. It’s a brand new iPhone 5S but it now happened already 4 or 5 times in 2 days.
It feels like a hardware/iOS problem and not a network issue. It happend with iOS7.03 but I just see 7.0.4 is available so will install that one now.
Thanks in advance for feedback
Best regards,
Marco

Hello Jeff,
Thank you for providing so much detail about the issue you are experiencing with the audio on your iPhone. I would be concerned too if the audio on my iPhone was not working unless using speaker phone. I found an article with some steps to take when you are experiencing issues like this:
iPhone: Can't hear through the receiver or speaker

Fascinate Market all of a sudden stopped downloading apps - pls help

I bought a Samsung Fascinate today. It never downloaded any apps. I did a Master restart, and it started to download apps (about 4) - then it stopped downloading. I click on "install," it says "application will download" and then it immediately says "download unsuccessful."
I called customer service at Verizon three times - spoke to their tech guys - and they recommended getting a new phone.
So, I went tonight and got a new phone. It was working great - downloading apps.
Then all of a sudden, it stopped downloading apps and every time I try to download anything, it says "download unsuccessful."
So it's not the phone, I gather. I don't know what to do. I'm so frustrated.
Thanks for any and all help you can offer. I really like the phone and don't want to get a different one, but I need to be able to download apps. Clearly, customer service/tech support is worthless (they were Googling the problem to help me - I can do that!).

Letstry some different steps to try to correct this problem.
First you would want to verify that you have the 3G coverage on the phone.
You can verify that information at the top, next to the signal bars.
Then could I get you to do a soft rest on the device.
Press the Power key.
Touch Power off.
Touch OK.
Press the Power key to power on the device.
Then dial *228 send and option 1, then dial *228 send and option 2.
If you are attempting to download the same application, try downloading a different application to see if you get the same error message.
Then try this step:
From the home screen, select Applications.
Select development,
Then allow 3rd party applications.
Finally before downloading applications try stopping the applications that are running in the background.
From the home screen, select Applications.
Select Running Services, Choose unnecessary applications and Force Stop.

Why can't I print all of a sudden? - Can you suggest?

I have networked a printer through my new airport extreme.
Everything "had" worked fine. I was able to print wirelessly with my Macbook and a hardwired PC. It has been several weeks since I've tried printing.....and it won't work? I have no idea what happened!
The PC just stops and says printing error. The Macbook gets to 29% in print status and just sits there...?????
Can anyone please give me some suggestions on what to check? I would think it's not a computer problem since two computers are having trouble. Is there some type reset function to try?
Thank you!

I got it working, but I don't believe I can explain how! Unplugged things a few times. Was able to print a simple word doc, but it took about 3 minutes!! Even though I had a full signal and a green light, I wasn't able to get on the internet either.
All of a sudden the internet worked and I was able to print a page much faster>>???
Don't understand what was going on, but it works now.
Thank you!

Macbook wifi not working all of a sudden

So while doing a fresh install of ML on my unibody MB I ran into a snag just a few moments ago. Everything installed no problem, I updated to 10.8.1 yesterday and all was well. Today I installed a few other apps (skype, iLife 09) with iLife requiring a reboot. Once rebooted I was unable to get a wifi signal.
At first the little icon at the top bar was blank indicating wifi was turned off. I selected turn wifi ON and it now says looking for networks and after a few moments it fills the blank icon with grayed out lines, yet it never finds a network to connect to, just keeps looking. In system prefereces/network the wifi status shows to be OFF. Pressing "turn wifi on" next to the status does nothing. The button lights up blue when pressing it but it has no effect on the network status. Network Name shows a grayed out "Wi-Fi Off". I have done several re-boots and several shut downs and battery removals all without solving the issue. Using network diagnostic does not turn the wifi on either, just gets stuck on scanning. Connecting an ethernet cable gets me online no problem.
My other mobile devices indicate that my wifi network is alive and well. This led to me to think that perhaps the hardware crapped out, which would be strange that it did that all of a sudden. So I took the hard drive out and put it my SSD that resided in my MB until a few days ago (with everything still intact on the drive). Booted up and wifi is working fine. The only difference is that the SSD is running 10.8. I was thinking of updating it to 10.8.1 to see if that kills the wifi but I did the update on the other drive yesterday and had no problems with it after a reboot. The problem started today after the skype and iLife install and reboot. In other words the MB ran 10.8.1 fine for 24 hrs and I find it strange that iLife or Skype would cause this issue but that is when the problem started, so I'm stumped.
Is there a way to force wifi to turn on in terminal? Or any other suggestions? Anyway to go back to 10.8 or do I have to re-install everything from scratch?
Thanks, Mark

HT4356 all of a sudden I cannot air print from my ipad or iphone - I can still print from my laptop - don't know how to fix

All of a sudden i can no longer air print from my iphone 4S or my ipad 2
Need help
I can still air print from my Dell laptop

Hello rcappel,
Thank you for the details of the issue you are experiencing when printing from your iPhone and iPad. I found a couple of resources I recommend for the issue you described.
First, I recommend following these steps:
If you are unable to print, or if you see the message "No AirPrint Printers Found"
Verify that the printer:
Has power and is turned on. If it has power, turn the printer off and then on again to see if that resolves the issue.
Is connected to the same Wi-Fi network as the iOS device.
Has the latest firmware version installed.
Has paper with enough ink or toner installed.
Is free of any errors displayed on the printer's control panel.
If necessary, consult the printer documentation or contact the printer vendor for help with the above steps.
You can find the full article here:
AirPrint Basics
http://support.apple.com/kb/HT4356
If you are still having trouble printing after following those steps, I recommend these steps:
Wi-Fi disconnects, or signal strength is less than expected
Move closer to the Wi-Fi router (access point).
Check for sources of potential interference.
Remove any case, stand, or other accessories from your iOS device and see if signal strength improves.
Reset network settings by tapping Settings > General > Reset > Reset Network Settings.
Note: This will reset all network settings including: previously connected Wi-Fi networks and passwords, recently used Bluetooth accessories, VPN and APN settings.

Some things to try first:
1. 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.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. 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
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button
