If I have my iMac internet sharing turned on, the Airport Utility won't recognize the Airport Express I want to use to stream iTunes to my stereo. When I turn the iMac internet sharing off, the Airport Express appears but calls itself a base station.

If I have my iMac internet sharing turned on, the Airport Utility won't recognize the Airport Express I want to use to stream iTunes to my stereo. When I turn the iMac internet sharing off, the Airport Express appears but calls itself a base station. I just bought the Airport Express and it's not clear how I should set up my System Preferences for Sharing. Thx

Yes. Unfortunately the stereo is too far from the wired ethernet connection My iMac is connected to the internet using an ethernet cable from the DSL modem (plugged into the wall, not wireless). The Airport Express is plugged into an outlet 25' away from the iMac and connected to my speakers. I've turned on the iMac Airport wireless Internet Sharing, hoping to stream iTunes to the Express connected to the stereo. The iMac Airport picks up several neighborhood networks so I know it's working (and I connected my iPhone wifi to it just to check as well).
When I use Airport Utility to set up the Express, the only time Utility recognizes the Express is when the iMac Airport is off. When I turn on the iMac Airport, the Airport Utility immediately loses the Express and asks to rescan.
Maybe that explains my problem better.

Since updating to Lion the iMac won't recognise the external hard drive (maxtor) when waking from sleep mode,

Hi All, Since updating to Lion, my imac won't recognise the ext HDD (Maxtor) when waking from sleep mode, I have tried another port, diisc utility (Ext HDD not listed in here) but nothing works. I now find that I have to restart the imac to get the drive recognised..which is fine until the imac goes into sleep mode then I lose the drive and have to restart etc etc.....anyone suffering same issue. The Ext Drive worked perfectly until the upgrade..

Thanks for this, and apologies for delay in replying...in between seeing your post I backed up the ext hdd to another mac and used the disc utility to erase and repair and then re mounted the ext hdd. OK. I have then tested the ext hdd being recognised when waking from sleep mode a few times and everything appears to be fine. If this doesn't work (long term) I will follow the instructions as you have suggested....
I now have a new problem with my HP printer (Photosmart Plus) which is not being recognised by a new wireless router..Ok whilst the router is switch on and I have reconfigured the printer..but when the router is switched off overnight and then switched back on...I get a 'printer is not connected' message and have to go through the re configure routine all over. I am minded to think this is a router problem as the same issue is happening to my wifes Mac Book Pro (which is only a few weeks old)...any suggestions..

Mac won't recognise the CD in the Optical Drive

My MacBook Pro won't recognise the CD in the Optical Drive. So I can't eject it put new one in.
Why is doing this? How do I solve the problem and get my CD out?

Are the CD's you are trying to install store bought CD's?
What you might try doing if the CD drive is not showing up under the source is going to file and then clicking on Add to Library within iTunes. Find the CD inside of My Computer and trying to add the music.

I've just bought a MacBook Pro The system won't recognise the serial number even tho I've typed it in carefully several times The helpline is closed Any ideas?

I've just bought a MacBook Pro The system won't recognise the serial number which I've copied very carefully several times from the underside of the computer
The helpline is closed Any ideas? I don't know what the operating system is - how do I find that out?

What are you trying to do?
The operating system can be found by going to the Apple menu and selecting "About this Mac"
Under "Mac OS X" should be the Version 10.6.x, clicking Software Update will update the operating system via the internet.

HP ProBook 4530s orange blinking led, won't recognise the power cord

Hello!
yestarday I tried to open my laptop but it didn't start. i thought that maybe the battery was empty so i plugged the power cord, but nothing happened.
then I noticed the led near the power cord blinking orange. After a fast googling i came to this thread ( http://h30434.www3.hp.com/t5/Notebook-Hardware/charging-light-blinking-problem-with-hp-probook-4530s... )
using the 8-step guide I managed to boot the laptop just to realise that it won't detect the power cord!
It was really strange, because when I noticed this, my battery was already at 2%!
I shut down the laptop, and tried to open it without the battery, it booted normally, but it still can't detect that the power cord is plugged in!!!!!
On the other thread some mentioned to update the bios, but in my case where it can't detect the power cord, that's impossible, because the procedure requires the laptop to be plugged in.
Now the laptop won't start normally, I have to keep the power button pressed for 40 secs and then plug the power cord. In addition it won't work only with battery, and that is my biggest problem!!
What should I do now?

IMac,airport extreme router, IPad2

Before I brought the iPad2 home, I set up my airport extreme to work with my ISP and I could connect my iMac wirelessly via safari to the Internet and surf the web from anywhere in the house. I brought the iPad2 home, and it immediately found the network. I typed in the password and it connected, no problem. However, if I want to connect tog the Internet now with my iMac I must plug it in to the router, it won't work wirelessly. Also, if I am connecting to the Internet via the IMac plugged into the router, I can't access Internet with the iPad2. When I go into airport utility to see if there is an obvious change I should make, it indicates that the router settings don't need changing. So, I know there is something I must change, but I don' t want to foul up the router settings, as I do have Internet access, but the network is not letting more than one device access at the same time.
Would appreciate some input as to what steps I might take to correct the problem. I think it must be something very simple, but I haven't hit on it yet after several attempts.

Theoretically possible using:
System Preferences>Sharing>Internet Sharing
Choose the iMac wi-fi and configure a network name and password.
You may need to check the hotspot terms and conditions to check that it will allow more than one device/computer to connect to the internet. As you are probably aware AppleTV cannot access login screens for wi-fi hotspots only set normal local wi-fi settings.
Another option would be to run ethernet firect to AppleTV2 - if that's impractical consider a pair of mains powerline home networking plugs that can bridge the gap to give ethernet to a distant device in the house - check makes like Netgear, Devolo etc.

IMac + Airport extreme + airport express + iTunes = no music?

I bought an iMac in February with Airport Extreme. Wireless internet & wireless printing have been fine with this.
At the weekend I bought Airport Express so I could wirelessly play my iTunes through my stereo; I have connected my Express to my MD socket using a digital-optical to mini-toslink cable, but I get no sound from the stereo.
The Express & Extreme set-up & configured in the straightforward manner as you'd expect, so I don't think that's the source of my problems.
I'm not a computer-whizz, but nor am I a complete div, but I'm sure it's a really straightforward fix I've overlooked.
Please help?

Let's double-check your AirPort Express Base Station (AX) settings ...
To set up AirTunes on the AirPort Express Base Station (AX), either connect to the AX's wireless network or temporarily connect your computer directly (using an Ethernet cable) to the Ethernet port of the AX, and then, use the AirPort Admin Utility to check these settings:
AirPort tab
o Base Station Name: <whatever you wish or use the default>
o Wireless Mode: Join an Existing Wireless Network (Wireless Client)
o Wireless Network: <select the existing wireless network>
Music tab
o Enable AirTunes on this base station (checked)
o Enable AirTunes over the Ethernet port (optional)
o iTunes Speaker Name: <whatever you wish>
o iTunes Speaker Password (optional)
In iTunes:
iTunes > Preferences... > Advanced > General
o Look for remote speakers connected with AirTunes (checked)

IMac / Airport Extreme

My new iMac has Airport Extreme. Currently I use the RJ45 jack to connect to my cable modem. I just purchased an Airport Express for the Airtunes feature. Can I enable Airport Extreme to link with the Express and still be wired to my cable modem? Or do I have to go completely wireless? When I go to the Airport utility on the iMac, everything is grayed out. I don't see anything in the manual about this, and I don't want to start changing network settings without knowing first. Thanks

Watch out for confusing terminology. "AirPort Extreme" is the name of one of Apple's AirPort base stations. Is that what you mean, or you mean that your iMac has high-speed Wi-Fi capability.
If the latter, if you want to use an AirPort Express, since it only have one Ethernet port, you'll have to connect that to your cable modem. That in turn means that any other connection (other than an audio connection to the Express) will have to be wireless.

Applecare for iMac - Airport Extreme registration

I have an iMac registered with Applecare, and I'm trying to register the same applecare with my Airport Extreme. Does anyone have any idea how to do it? I used the same activation code for iMac, but it won't let me register.
Thanks in advance for any help!

If you read the applecare agreement, you will find airport extreme, keyboard, and mouse etc. are covered automatically by iMac Applecare when you use these devices with the covered iMac. Anyways.. i got the answer from another forum, i actually don't need to register it online... Thanks all the same!

G5 iMac + Airport Extreme = Fail?

I have been struggling to get my new Airport Extreme to work with my already existing and functioning internet. The DSL modem and the Airport unit don't seem to want to communicate with each other. After I have appeared to have everything set up correct and I click "update," it reads "This device and its network services will be temporarily unavailable." After all is said and done, it still doesn't work at all. I have tried everything I can think of to get everything in sync with each other including:
- Restarting Airport
- Plugging in modem to Airport THEN plugging in Airport (also tried reverse)
- Restarting Modem (repeatedly)
- Resetting Airport
- Updated Airport Utility
- Plugging the modem into both the Ethernet port AND the WAN port
I have an Airport Express which is seeming to work fine, but I want to use the Extreme as the primary router, not the Express. Any hints, tips or advice? Do I have a bogus router??? HELP!

Scooter, Welcome to the discussion area!
That is all you need to give your G5 iMac the ability to connect to 802.11b/g Wifi networks.
