Airport express light is green but is not working

My airport express is on,light is green, all of my computers see it though Airport Utility however the computer that is 2 feet away has no internet abilities. It however see the house network,sign in but no not able to communicate with other house computers as well as the internet. 'The lights are on but no one is at home'

If all the other computers can connect to the Internet, try power cycling your entire network.
Power everyhing down on the network...all devices, order is not important
Wait a moment, then start the modem first and let it run a moment by itself
Then start your AirPort Express the same way
Continue starting the devices the same way until everything is back up
Check for Internet connections on all devices
Please post on your results

√using successfully airport express for internet/ when hooking up new airport extreme light glows green, but does NOT appear in devices seen????airport wifi devices

using sucessfully airport express for internet
when hooking up new airport extreme light glows green, but does NOT appear in devices sesn in 5.6 airport wifi devices
wanting to use extreme at base and express in another part of the house

How is the express getting internet? What modem is it plugged into?
How is the extreme setup? New extreme cannot be setup with 5.6 utility.. you must use latest 6.3. Which also means you cannot setup from computer using less than Lion .. or you must use iOS with latest utility but it has limited configuration cf the computer version.
IPv6 is also needed.. turn on local link.

Solved my problem by blacklisting "carl9170", so only "ar9170usb" module is loaded.
Blacklisting "ar9170usb" did not work here!
Thanks
EDIT:
After update to Kernel 3.0 the ar9170usb module was removed. Now its not working anymore.
When i load the carl9170 module, it says
[ 2.979833] usb 3-1: firmware not found.
Do I need any additional firmware?

My power cord lights up green, but is not charging my macbook pro. Any idea what I should do?

I have a MacBook Pro, about 2 years old. When I plug in the power cord, it glowa green but is not charging the computer. Any ideas?

Reset the SMC:

If that doesn't get it charging again, see this article:

If you have access to another AC adapter, see whether that one works better.

Hello, My white McBook (2008 or 2009) recently stopped turning on. When I hook up the Magsafe power adapter, the light shows green, but the computer will not turn on, or make a sound. I've tried the re-boot option, but nothing works. Please advise!

Hello,
My white McBook (2008 or 2009) recently stopped turning on. When I hook up the Magsafe power adapter, the light shows green, but the computer will not turn on, or make a sound. I've tried the re-boot option, but nothing works. I first thought I needed a new battery because the lights at the back are all off, but shouldn't the computer turn on once the power adapter is hooked up and the light on the Magsafe adapter shows green? I'm a computer doofus, so please be kind. Please advise! Thanks in advance.

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.

Apapter light is green, but MacBook is not fully charged.

My MacBook's power adapter light stays green, but my computer is not fully charged, the indicator in the menu bar says 98%. I am very confused, anyone have a possible solution?

The charging circuitry turns off once the battery is fully charged. It will come on again when the charge level drops below 95 percent. Until then the battery is fully charged so the charge indicator on the adapter will stay green.
If your battery never attains 100 percent charge level it may be because you've never calibrated the battery.
If you've calibrated the battery but it still will not charge fully or doesn't hold the charge, then the battery may be defective. You can have it replaced under your warranty by taking the computer to an Apple service center or calling AppleCare. Click on the Contact Support link at the bottom of this page for AppleCare's phone number.

Find my friends Icon disappeared after upgrade to ios 8. I tried restarting as well as reinstalled the app but its not working. I can find it in Usage, but not in spot light. Pla help!!

I have exactly the same problem on a 4S on iOS 8. Have tried uninstalling, deleting FMF from backup, resetting phone and restoring from backup, but the problem remains. Sometimes the icon appears on a backup Home screen in iTunes, but it never appears on the phone itself. The app is accessible by going to the store, purchases and opening it from there. The app appears to have been running the whole time, but becomes invisible anytime I return to the home screen.

My airport express is setup, the light is green but I have no Internet connection

i have setup my airport express the light is green but I get no wifi

I have a macbook pro 13'' with MAC OS X. Recently bought and installed airport express when it does not drop the WiFi conncetion it works great. Getting frustrated with the fact that I keep losing my WiFi connection, when this happens I check my iphone and I can access the internet do problem while my Macbook pro cannot? After doing some research on the problem I found out that this is not an uncommon problem specially or those who have upgraded to MAC OS X. From what I understand there is a a bug in the WiFi connection chip! Am going to the Apple store today to see what they have to say. I hope there is a fix for this!

IPhone 4s bluetooth connects but does not work handsfree

I was using my Macbook when it suddenly shut down, I was updating a program so I had the charger on even though there was still 90 percent of power in the computer. I tried to turn on the computer several times but is not working, what can I do?

I was using my Macbook when it suddently shut down, I was updating the operating system so I had the charger on even though there was still 90 percent of energy. I tried to turn my Mac several times but it doesn`t turn on, also the green light of the charger is not working, it`s looks like the charger is dead too. What`s wrong with my Mac?

Try resetting the SMC.
MacBook and MacBook Pro with a battery you can remove
Shut down the computer.
Disconnect the MagSafe power adapter from the computer, if it's connected.
Remove the battery.
Press and hold the power button for 5 seconds.
Release the power button.
Reconnect the battery and MagSafe power adapter.
Press the power button to turn on the computer
To reset the SMC on newer Mac portables with a battery you cannot remove
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

My charger light is green but my computer isn't charging

I am absolutely freaking out. My charger is plugged in, and the light is green, but my computer remains at 35%, it's not dying, but it's not charging. I have done MANY trouble shooting excersises, I've done the SMC thing, and that didn't work either. I've tried plugging it into many different sockets but obviously (since i'm asking) that hasnt worked either. As you can tell from the imformation below, its not fully charged, but it's also not charging. I dont know if this information helps but I've had my computer since October 2013, it's now April 2014, so thats 6 months I've had my computer. Also, usually as soon as i relaize it has reached 100% i take my charger out, though sometimes if my computer is dead and I'm leaving the house, i leave it sleeping but charging until i get back home, also i don't frequetly shut it down, i simply leave it on sleep. ADDITINALLY I don't live in a country that has ANY Apple stores or specialist.. so sadly going to see a professional is out of the question, unless of course i can speak with them on the phone?

brittbien,
no, that fact is not relevant to the problem.
While waiting for your friend, you could take a look at your charger to see whether it was made by Apple or not. Is there an Apple logo in relief on two of its sides? Does one of the other sides have text that states “numberW MagSafe Power Adapter”, where number is either 60 or 85, and below it “Designed by Apple in California”, and at the bottom of the text there, a trademark and copyright claimed by Apple Inc.?

I logged in to fb but could not 'work' anything, changed browser to chrome google and everything worked, why is this?

I could login, could read everything on fb but could not 'work' on fb, could not 'like', not post, not access anything.
My tech suggested changing from firefox to chrome google and everything worked.
Only other problem is that windows has taken over the posts of my photos and I can't see the photos now, just little green box in middle of screen unless I click on the box and it opens up the photo. How do I get my photos back now, as well.
Am going back to firefox once more to see if everything is cleared up.
Any suggestions about getting photos 'released' would be good.
Thank you in advance.
