My ibook doesn't detect an existing wireless connection...please help

Hello,
just moved into a new house with wireless connection. all the other computers (PCs) can easily detect the wireless signal but my iBook doesn't. The airport is working properly since I can detect wireless connection in the university, cafes, trains etc...
the wireless router is a belkin.
Do you know if some special settings are required to be detect it or if there are some settings that can exclude my airport from the network?
please help me.... that's so frustrating!!!

The Belkin router might have been set up to use MAC-address filtering. In that case, make sure to add the MAC-address of your Airport to the list of addresses allowed to access the router.
Also, if the wireless connection name (SSID) is hidden (= closed network) your iBook might not see the network untill you explicitly define the network as a new Airport network connection.

Wireless connection PLEASE HELP

hello i am trying to use my wireless on my mac book it says it has got a signal and is working fine, but is not letting me use the internet and log onto msn etc anyone know how to set up my mac!!???

When I first got my macbook, I had similar issues. Here are a couple of things you can do that might help you out.
1. Try turning off all the security features on your wireless router (temporarily)
2. Try to connect, if this works, then continue on
3. Turn on the security features that you want (WPA, WEP, etc) and make note of what you used. You may want to reset the router password as well.
4. Configure the AirPort to use the settings from step 3.
Hopefully all will be well. It took me a couple of tries with my 2WIRE router/modem. If you are using WEP, you might want to make sure that you choose WEP hexidecimal. That solved the issue for me.
Good luck...

WRT54GS cannot detect an active internet connection. HELP!

Ok well just recently, I don't know why though but my router won't detect an active internet connection from my Cable Modem. I have my Router and Modem connected so I can play Xbox in my room. Well since my router can't detect an active internet connection now since the new Xbox update doesn't allow you to enter the encryption key anymore, I can't go on Xbox live because of it. I've tried changing the ethernet cable in different ports and it still doesn't work. If someone can please help me with this, it would be greatly appreciated. Thanks.
Solved!

1. Press and hold the reset button for 30 seconds.
2. Then, unplug the power keep holding down the reset button for
another 30 Seconds.
3. Plug back the power back in, and keep holding down the reset button
for 30 Seconds.
4. Release the reset button.
To re-configure your router follow this

FCE 4.0.1 can only capture DV/HDV which is produced by cameras using Mini-DV TAPES and cameras shooting AVCHD which is a high definition format.
If your camera shoots standard definition on Memory Cards, DVDs or Hard Drives it will not work in FCE.

IBook won't boot after broken wireless connection trying to update OS

Trying to help my kid with his iBook via telephone calls. He was updating the OS over a wireless connection, lost the signal which apparently froze the machine. When he rebooted it wouldn't go past the blue start-up screen with a spinning gear. He's used the install disk and disk repair, which said it repaired one volume but not a second one (not sure what that means). But no luck with rebooting back into his machine. He then tried to boot up in "safe mode" but that doesn't work; gets the blue screen and spinning gear again. He's got a lot of stuff on his hard drive and is understandably concerned about the best way to get the machine back to normal and still have the contents of the hard drive. Any suggestions? Thanks in advance for any help.

Hello andreaparra,
Thanks for using Apple Support Communities.
I found the following article that will help you in resolving this issue, where none of your devices are being recognized by iTunes.
iOS: Device not recognized in iTunes for Windows
http://support.apple.com/kb/TS1538
If you get to the part where it asks you to uninstall iTunes, even though you have done it before, be sure to uninstall iTunes and the other components in the order listed.
Take care,

Hooking up Mac Powerbook to existing wireless connection

I have just purchased a powerbook and airport extreme base station. Currently my roommates have a wireless LAN connected through a dell desktop.
1) Can I simply hook up to the LAN through the existing wireless router or will the current router need to be switched and replaced by my airport extreme?
2) If I need to switch to the airport extreme, will my roommates laptops and the dell pc be able to connect using the airport?
Thanks.

Yes

I had a similar issue with a MacBook Pro. When connecting the network cable, the network preferences would show 'not connected'. I thought it was hardware, but when I transferred the user to another Mac, I found that that ethernet device all the sudden stopped working as well.
I was able to get the ethernet back with:
System Preferences
->Network
->Assist Me...
->Diagnostics...
At some point the ethernet device went green and all was well.
Maybe this will help.

Detect loss of wireless connection

GOAL : physicians in a hospital getting access to web-based JSP content through a Pocket PC browser(IE) and wireless connectivity. We already have the "normal-size" JSP pages for desktop computers and we'd like just to provide a reduced version of theses pages to browse on a PDA.
PROBLEM : Even with a well designed WLAN with good access point placement, you may experience connection loss. And it's a problem when browsing JSP pages : imagine submitting a form when you're suddenly offline : you'll get a 404 or something similar -> not serious.
QUESTION : If I port our application in the Personal Profile Xlet framework, Would it be possible to detect connection loss in an Xlet or somewhat... then it could set the rest of the app to work in a kind of degraded mode. How can we manage that ?

You could have a thread which is dedicated to managing the apparent connectivity. It connects to a well known location, if it cannot connect then you are assumed to be disconnected and the application should downgrade. The routines that handle networking should be able to fail gracefully and not generate exceptions which would terminate the program. As an example you can update your stocks whenever theres a connection but if there isn't one you can always show the value and the last time it was successfully retrieved.

My Mac doesn't detect my windows DVD for bootcamp, help?

hi , i just grab my Windows 7 DVD for installing windows on Mac using bootcamp , but my mac doesn't detect my windows installation disc in boot menu... how to resolve?

You're not alone - I'm installed Windows (8 Pro 64-bit) on a MacBook Air Mid 2013 yesterday from the OEM/system builder media, and Boot Camp Assistant 5.0.4 didn't recognize the DVD. It asked for an .iso disk image instead, and I created one in a UNIX geek way**, but if you're an average mac user, you'll want to create one using the Disk Utility:
1) Open the Disk Utility. This is in the Utilities folder (go to a finder window and type command-shift-u)
2) Click on your DVD to select it.
3) In the File menu, select New -> Disk Image from "HRM_CCSA_X64FRE_EN-US_DV5"… (or your Windows disk title)
4) In the Save sheet, select Image Format: DVD/CD master. The Disk Utility saves this with the file extension/type .cdr, but this is the same file format as .iso. When the Disk Utility has finished, find the file you save and change the file extension to .iso.
5) Launch Boot Camp Assistant and select the .iso file as the source of your Windows installation.
Since I have a MacBook Air, the windows source was copied by the Boot Camp Assistant to a USB flash drive. MacOS X restarted and Windows was installed automatically, but the Boot Camp driver installer wasn't automatically launched at the end of the Windows install. I opened the flash drive's BootCamp folder and double clicked setup.exe.
Voila! The best trackpad anywhere! Network! Sound! Brightness control from the keyboard! The best Windows 8 computer!
** In Terminal: diskutil list; diskutil unmount /Volumes/HRM_CCSA_X64FRE_EN-US_DV5; sudo dd if=/dev/disk2 of=win8pro.iso. Use the output of 'diskutil list' to match your Windows 8 CD/DVD to a disk# for the 'dd' command. Be very careful.

AE Works with Ethernet Cable, but not Wirelessly. Please Help!!

I purchased the AE to run music streams via Airtunes from my wireless router/PC upstairs to my stereo downstairs. When I hook everything up upstairs with the ethernet cable, everything works like a charm, but the moment I remove the ethernet cable, the AE is not being picked up by the network. I set everything up for the wireless network (while the ethernet cable was hooked up) and have a green light on the AE, but when I try to use it wirelessly, it is blinking amber and not appearing within AirPort Utlity (only when hooked up with ethernet). I have a Westell 327W Wireless Modem/Router and could use some advice as to what I am doing wrong to get some tunes downstairs.
Thank you in advance.

Hi:
I was chasing this very topic for a long while, then took a break.
You are suppose to be able to stream music from your PC to external stereo speakers via iTunes, thru an Airport Express (AE) wirelees connection.
Here's my status:
It is pretty easy to get a wireless connection up & running so that you can play music from your laptop/pc to external wirelss speakers via iTunes, thru AE.
I have that up & running. The problem comes in when trying to add the Airport Express to an already existing Linksys router's wireless network. When setting
the AE up, you'll most likely get 4 error messages that have to be addressed before you go from from a flashing amber LED to a solid green LED. If you are just using Apple's ad-hoc wireless conncetion, you'll need to use Airport Utility to address the 4 issues. Basically, Airport Utility doesn't know how to address AE, since it doesn't have any IP address to a network. The other 3 are simlar problems. If you just tell Aiport Utility to ignore each of these problems, you will get the solid green LED on AE, and you'll be able to stream music directly from your PC to your speakers, wirelessly, once you finish the AE configuartion, and Airport Utility reconfigures the AE.
I have my HP laptop and printer setup with a Linksys 54G Router and Printserver,
so that the laptop and printer communicate wirelssly via the Linksys Router.
Now comes the fun...trying to add the AE to this already existing wireless network. I could get the AE to work when I had an Ethernet cable connected directly from a port on the router to the AE, but when I disconnected the Ethernet cable, the router no longer saw the AE in the network. I followed all of the instructions in the Airport Utility software, went seeking advice on this
newsgroup, the web, etc. Found lots of good information, but a lot of it was outdated.
I have my Linksys wirless network setup with WEP-64 encryption.
From what I have gathered, it is much easeir to add the AE to a WPA/WPA2 network, than to a WEP64/128 network, just because of newer protocols.
The problem that I have is that WPA encryption works much slower for me than
WEP encryption. Example: iTunes is roughly 60 MB is size. Downloading it
using WPA, results is a download time of 22-23 minutes; where a download
using WEP-64 takes 75-80 seconds !
In the past, what I was trying to do was add the AE to my already existing
wireless network. Now, I have a wireless network for the AE. I want to try to add this network to my already existing wireless netowrk for the Linksys router.
I just haven't taken the time to try it yet. From what Apple tells me, Linksys makes this setup messy. The fact that the AE works by itself proves that the
device is OK.
For a history of the problems that I have been chasing in trying to get the AE setup and added to my already existing Linksys router network, visit the following link in the list of "problems" on this Apple newsgroup's web page.
Search for the folowing topic title:
Problems Setting-up Airport Express to Play Music thru External Speakers
Currently, is is at the bottom of page 12 of this discusssion group.
The info in it may be useful to you.
Please let me know if you get yours up & running in the Linksys wireless
network.
Thank you

Ipod nano 8g not detected by windows and itunes please help

ok i recently got an ipod nano and i havent been able to put anything on it cuz it isnt detected by my pc. it just says usb device not recognized when i connect it. BUT i can still charge my ipod so i dont think its the ipod or the usb cable. the only thing i can think of is having the correct drivers. maybe one of em is corrupted or something? im gonna try to use itunes 7 and see if that works, but if it doesnt, idk what to do then. help is greatly appreciated. thank you

If you have tried everything in these articles, then it needs service.
iPod battery doesn't charge.
Sad iPod icon.
What does this picture on my iPod mean?
PC doesn't recognize the iPod is connected.
The sad iPod icon is usually indicative of a hard drive problem, and if under warranty will be repaired/replaced free of charge, although after 6 months of the warranty has expired there is a handling charge.

Mac Mini not detecting display....please help

I just bought a mac mini and the plan was to run it through my tv using an HDMI cord. When I go to set things up. I get to the display section in "system preferences" and I started playing around with resolutions to see which would work best with the tv that I have. All the sudden the tv screen went black and now the tv doesn't detect the mac mini through HDMI. After restarting the computer the apple logo would come up and everything would start to boot and then it's like the tv and computer would drop the signal. I don't think that it's something that I done with the resolution.
I checked and seen that this is a common problem, but I don't know how to fix this problem. Any advice is good advice and I really appreciate it.

Will that reset the display options?
David.Austin.Allen wrote:
This is common if in trying new resolutions you hit upon one that is not compatible with your TV.
Restart pressing & holding the Shift key until the gray screen with the spinning cogwheel appears. This is a slower startup as the Mac is running self diagnostics. When the Desktop appears go to System Preferences and reset the resolution to the correct setting. Restart normally.

At the top of iBooks, tap "Collections", select PDFs, or if that's already where you are, select any other Collections options to see if your file shows up. If this doesn't work, well, I'm not sure what to tell you.
