Aluminum iMac has poor Airport throughput

Hi,
I am wirelessly connected at 54Mbs. I'm on a 10Mb/sec connection at the WAN. My wife's first gen Intel iMac can max out the connection but I can only get 1/3 of that speed. I have tried three different routers and have gone so far as to place them directly next to the new iMac with no change. I am beginning to think there may be a software driver issue limiting the throughput on this machine. I'm wondering if other folks are having this issue with their aluminum iMacs?

Karl, Welcome to the discussion area!
Check the photos in KB 108039, Properly attaching the antenna on an AirPort Extreme Card to ensure that the antenna wire is properly installed. It can take more force than expected to get it installed correctly. It should look like this:

MacBookPro has poor airport reception

My MBP only has a fraction of the reception of our MacBook. It seems to be getting worse with each OS upgrade. Each time the computer starts it takes a long time to scan and find any wireless network. We are not using Real Player 11.

if reseating the card and making sure the connection is okay doesn't do anything, you should try pulling the /library/preferences/systemconfiguration folder to the desktop and restarting the computer. make sure you are familiar with your network settings, as this will wipe them out and you will have to reconfigure them. so if you are unsure about anything, then write them down. if that doesn't work, the next thing i would do is a hard reset of the airport extreme base station and create a new wireless network. http://docs.info.apple.com/article.html?artnum=107451 i know this sounds absurd, because the other computers are working fine, but i have seen it work many times so it is worth trying!! good luck.

I have a Power PC G4 which is running on OSX 10.5.8, it has the AirPort utility but cannot connect to the internet as my iMac can, I think I might need an AirPort Card? Is that the case or do I need something different to connect to a wireless modem?

Welcome!
Only one variant of the PowerMac G4 could use the faster Airport Extreme Card. The rest used the original Airport card that is pretty slow.
To get fast wireless without buying more than one thing, consider this:
http://eshop.macsales.com/item/Edimax/EW7722IN/
It goes in an available PCI slot
There are USB solutions also. However, all PowerMac G4 towers had only slower USB 1.1 ports, so any USB wireless adaptor can only run at about wireless 'B" speeds (slow) unless you also install a PCI USB 2.0 adaptor card. Doing that would allow a USB wireless adaptor to run at its maximum rated speed. These items working together would accomplish that:
USB wireless "dongle:"
Newer Technology MAXPower 802.11n/g/b USB Adapter + Plug and play direct or with extension cradle
USB PCI adaptor:
http://eshop.macsales.com/Search/Search.cfm?Ntk=Primary&Ns=P_Popularity%7c1&Ne=5 000&N=7069&Ntt=USB+PCI
Each approach has its advantages. The PCI wireless card is a one-piece solution that takes up no desk space. The USB2 card+USB2 Dongle gives you more fast ports for transferring date from other external USB devices (primarily cameras and external hard drives) at hugely faster rates than can the original ports. I have a USB 2 PCI card in my G4 tower strictly for transferring images from my digital SLR camera in a timely manner.

SonyAVCHD video looks great in iMovie11 or iDVD7.1.2. When I burn a DVD it's terrible. If I freeze frame I see squares. The picture has poor contrast. I've viewed DVD on my 6-year-old, 24 in. intel 2.16 GHz iMac, and on TV. Help!

I just bought a very good quality Sony AVCHD camcorder. I also just upgraded my computer from Tiger to Snow Leapord. My iMac is a 6-year-old, 2.16GHz Intel 2 Duo, with a 24 inch screen and 3GB Ram.
My Sony camcorder HD video looks great in iMovie11 and in iDVD7.1.2., but when I burn a DVD "professional" it looks terrible. If I look at a freeze frame on the DVD I see image made-up of squares. The picture has poor contrast. It looks as bad as poor quality VHS. Do I need to get a new iMac to make this work? Is it possible to make a sharp, clear DVD from AVCHD footage with a 6-year-old iMac like mine?

That thread helped for a time. But now it seems as though my computer is back to slow again. But, some of the jargon is over my head as well. Not sure I knew quoite everything they were talking about. But thanks a lot for that, it helped I probably just need to reread it and follow the instructions again. Thanks so much.

My PC can connect to the airport extreme but with encryption it cannot connect to the internet my iMac has no issues, any help.

My PC can connect to the new airport extreme I just purchased but with encryption it cannot connect to the internet my iMac has no issues. If I open the airport exteme up and provide no security everything is fine which leads me to believe it is something with the encryption between the two devices. Not sure what step I'm missing here this shouldn't be this difficult.

Sorry, I should have been more clear. I am asking if the DNS IP addresses, not the IP addresses assigned by the DHCP service, are the same. DNS is like the Internet's version of the Yellow Pages. Your ISP typically will provide them to you or you can elect to use those provided by another source, like OpenDNS.
DNS is the service that translates a website's URL to its actual IP address so that you can access it. I am just trying to rule out that the PC is not configured properly with the correct DNS IP information.
The other thing to check is if the PC is configured to use a Proxy service. By default, it would not be.
Finally, what is the make & model of the PC. More importantly, if the PC is using either a PCI or USB wireless adapter, what is its make & model?

Replacement Displays for 20" Aluminum iMac

As I sit here staring at another gray background website that goes from dark gray at the top to light gray at the bottom, I keep wondering "When is Apple going to do the right thing and replace these displays?" The poor quality display is the only thing keeping this computer from being the best one I've ever had.

If you're still within the 14 day period, return it and get a refund. So long as people keep buying the new 20" iMac, Apple has no incentive to improve the quality of it. I'm concerned about how Apple is going to honor its warranty for people who have the white iMac. If Apple can't repair them, it is contractually bound by its warranty to replace them with a functionally equivalent computer. In the past, that's always meant that a person would end up with a new model that was actually better than its predecessor, but that's not the case now. Since the supply of white iMacs is running out, Apple will eventually be replacing defective white iMacs with aluminum iMacs. However, because of their poor quality screens, especially on the 20" model, the new iMacs are functionally inferior to the white iMacs, thus leaving Apple with no way to honor its warranty unless it replaaces defective white iMacs with new MacPros and Cinema Displays.

Apple Mini-DVI to Video Adapter doesn't fit my aluminum iMac

I previously had a 17" white iMac (pre-Intel) machine, and about 6 months ago I bought the mini-DVI to video adapter so I could connect it to my television. Worked like a charm. But I recently bought a new aluminum iMac, and the adaptor doesn't fit into the mini-DVI port in the back of the machine. It appears the adaptor and port are both male ends.
Has the port changed on the aluminum iMacs? The product description for the adaptor on Apple's website says it works with iMac (Intel Core Duo). Isn't the aluminum iMac an Intel Core Duo? I can't figure out why it doesn't fit and which cable I'm supposed to be using instead.
Any advice would be appreciated!

Hi Paul
Yes the Intel iMac [Spec's|http://support.apple.com/specs/imac/iMacMid2007.html] call for the (M9319G/A) Apple Mini-DVI to Video Adapter!

How to connect my old imac G4 (no airport card) to lynksys router

I am going to buy a new imac. I want to put my old G4 15" with no airport card installed into my daughter's room. I have a linksys wireless router WRT54G connected to my dsl modem. The linksys wireless router is linked to my imac via an ethernet cable. My laptop has an airport card that I can use the internet through. Can I put an airport express in her room and connect that way?

Oh, sorry, I was thinking you wanted to connect the AX wirelessly to the Linksys.
Yes, you can connect the AX to the Linksys with an Ethernet cable and then use the AX in "bridge" mode to allow wireless client to connect to it for Internet access.
To set up the AirPort Express Base Station (AX) as a bridge, using the AirPort Admin Utility, connect your computer directly (using an Ethernet cable) to the Ethernet port of the AX, and then, make these settings:
Network tab
- Distribute IP addresses (unchecked)
- Apply the new setting.
- Wait at least 5 minutes.

IMac has become slow and freezes up

For a few months now my iMac has been much slower than it used to be. Apps take longer to open, menu functions respond more slowly, folders and files take longer to open, pages longer to display, etc. Frequently the active window freezes and the colour wheel starts spinning for 10-15 seconds (it has been doing it twice since I started writing this sentence). This happens with all apps I am using, like Safari, Mail, Word and Excel, but particularly frequently in Logic Pro X. Sometimes when it happens (but not always), I get the error message "Disk too slow or system overload (-10010)". However, I upgraded to Logic Pro X about a year ago, and I never had this problem during the first number of months after the upgrade. I am aware that Logic uses a lot of CPU and memory, but, as mentioned, I also have the problem when Logic is not running. This leads me to think there might be something with the hard disk, although it beats me why it suddenly should have become slow. I am currently running everything from the built-in 1 TB hard disk. I have a 3.1 GHz Intel Core i5 CPU and 8 GB RAM. A full EtreCheck report with my system specifics is enclosed below. Can anyone help?

My home network has an Airport Extreme w/Time Capsule as the base and then an Airport Express and a second Airport Extreme to reach different areas of the house. Is there a way to use the second Airport Extreme for file storage on this network?

My home network has an Airport Extreme w/Time Capsule as the base and then an Airport Express and a second Airport Extreme to reach different areas of the house. Is there a way to use the second Airport Extreme for file storage on this network? Network is administered through an iMac running OS X Yosemite 10.10.2. Ideally, would like for the second Airport Extreme hard drive to appear on the list of devices in the Finder window.

Ok.. gottcha
The problem is network wise.. Yosemite is about equal to tin cans and string.. pathetic.
Here is my usual set of instructions to get anything working on Yosemite.
The best way to fix problems is a full factory reset of all the AE in the network.
Factory reset universal
Power off the AE.. ie pull the power cord or power off at the wall.. wait 10sec.. hold in the reset button.. be gentle.. power on again still holding in reset.. and keep holding it in for another 10sec. You may need some help as it is hard to both hold in reset and apply power. It will show success by rapidly blinking the front led. Release the reset.. and wait a couple of min for the AE to reset and come back with factory settings. If the front LED doesn’t blink rapidly you missed it and simply try again. The reset is fairly fragile in these.. press it so you feel it just click and no more.. I have seen people bend the lever or even break it. I use a toothpick as tool.
Then redo the setup from the computer with Yosemite.
1. Use very short names.. NOT APPLE RECOMMENDED names. No spaces and pure alphanumerics.
eg AEgen5 and AEwifi for basestation and wireless respectively.
Even better if the issue is more wireless use AE24ghz and AE5ghz with fixed channels as this also seems to help stop the nonsense.
2. Use all passwords that also comply but can be a bit longer. ie 8-20 characters mixed case and numbers.. no non-alphanumerics.
3. Ensure the AE always takes the same IP address.. this is not a problem for AE which is router.. it is a problem for AE which is bridged.. you will need to set static IP in the main router by dhcp reservations or use static IP in the AE which is tricky.
4. Check your share name on the computer is not changing.. make sure it also complies with the above.. short no spaces and pure alphanumeric..
5. Make sure IPv6 is set to link-local only in the computer. For example wireless open the network preferences, wireless and advanced / TCP/IP.. and fix the IPv6. to link-local only.
6. Now mount the disk of the second AE in finder... manually.
Use Go, Connect to Server and type in the AE ip address.
SMB://10.0.1.2
Where you will replace that address with the actual address. The network resource should be discovered and then it will request the password.. type that in and make sure you tick to save it in your keychain.
There is a lot more jiggery pokery you can try but the above is a good start.. if you find it still unreliable.. don't be surprised.
Do as much as you want of the above... not all of it is necessary.. only if you want it reliable.. or as reliable as Yosemite in its current incarnation can manage.
The most important thing is point 6.. mount the disk using direct IP address and not names.. dns in Yosemite is fatally flawed.
See http://arstechnica.com/apple/2015/01/why-dns-in-os-x-10-10-is-broken-and-what-yo u-can-do-to-fix-it/

I receive a not connected to the internet message several times daily on my iMac connected via airport to a time capsule which accesses the internet via cable modem.. When I input my password to enter network preferences, the connection re-establishes.

I receive a "not connected to the internet message" several times daily on my iMac connected via airport to a time capsule which accesses the internet via a cable modem. Software/firmware is up to date on the iMac (OSX 10.6.8) and Tme Capsule(7.5.2). Browser is Safari 5.1.
When I input my password at the prompt to enter network preferences, all the lights go green (ie... ethernet, ISP etc.) and the connection re-establishes immediately and states "the connection appears to be working normally".
It more of a nuisance than anything and seems to have started ocurring over the past couple of months. I also have a windows XP box also connected to the same cable modem that I never have internet connectivity issues with. I've verified all the physical aspects of the connections and can't see any evidence of any actual drops in the modem logs. I suspect it is just an intermittent communication loss between the Imac and the Time Capsule, but I am not very familiar with Mac equipment yet.
Just wondering if anyone has experienced a similar problem and what you did (if anything) to resolve it?
Thanks.

The AirPort Express will connect to your existing wireless network if the network is using WPA2 Personal or WPA/WPA2 Personal wireless security settings.
So, it can join the network as a client and then provide an Ethernet signal to your Time Capsule.
Be sure to configure the Time Capsule to operate in Bridge Mode so that it will be operating on the same network.

IMac Intel 24" - Airport Wireless Rate

Here is my setup:
1 - 24" Intel iMac 2.33 / 2 GB (Located 10 feet across from AP against a wall, in a large apt complex) Avg rate 13mb. I typically sit in front of the computer in between the AP and the iMac, though I see this low transfer rate without me in front of it and if I pull it out from the wall.
1 - Airport Extreme N Mounted 6 feet off the floor on opposite wall)
I have WPA2 Personal setup and WDS as Main, it is running firmware 7.3.2. There are 8 wireless clients connected (2 Macbooks, 1 Tivo, 2 iphone 3G, 2 AppleTV, 1 Wifi Cam)
1 - Airport Express N Located 5 feet to the left of the iMac on the same wall, connected to network via WDS, used as wireless bridge for HP Laserjet Printer (Average Rate 54mb)
Using iStumbler I have identified on average 8-14 other wireless networks in my area. I have adjusted my AP channel, moving it from crowded channels such as 6 or 11 to 3, 4, 10, 8 and 9... trying to keep at least 2 to 3 channels between my channel and the others I see.
Channels 1,2,3,4,5 and 10 don't work to well.. sometimes the iMac can never reconnect to the AP if these channels are selected. I have to use my MacBook to adjust the channel back a different channel... its pretty hit and miss... sometimes it works... some times it doesn't. The transfer rate will start out high... 120 and than drop settling on 13 no matter what channel with or without IR turned on. I avoid IR as it can drag down performance on its own and with 8 wireless clients already pulling on resources... I just avoid it.. doesn't seem to solve this issue.
Also, my Macbook Pro and MacBook can be positioned in the same location as my iMac and still maintain transfer rates of 120-130 on average.
I do not have a wireless phone in the house and the microwave is located on the other end of the apartment. the only thing near the AP is a LCD tv 3 feet below it. I have an external MyBook Drive sitting next to my iMac along with a HP Laserjet printer and ScanSnap Scanner... these devices are sitting level or below the imac... there are no shelves located in close proximity to the top of the iMac.
One other thing I am noticing... Airport Utility on my iMac has difficulty locating my base station at times even with full strength indicated in the menu bar.
All other devices connected to the AP average 54 -130 mb/s - This includes my AppleTV that is in a different room and has to transmit through a hollow wall. As well as my Tivo and Wifi cam.
The AP is set for 802.11n g/b compatible... though I have tried playing with this setting as well... not all of my network up to the N standard.. Tivo for example does not have a 802.11n adapter yet.
I have read through several support postings on various Mac Support Sites as well as this one... I have reset the SMU, deleted related Pref files and recently I did a Archive and Install of the system. At one point I did roll back the firmware on the AP based off feedback others had posted... no luck.
I have a feeling this is a hardware issue, either the Card in the iMac is bad or the Antenna is damaged or faulty.
I am looking for other suggestions... I want to avoid taking my computer in for repair as often it they come back in worse shape than when they went in...
Signal Stats

20 inch Aluminum iMac crashes after installing Mac OS X Combo Update 10.5.6

I have a school lab with 22 of the new 20 inch Aluminum iMacs. They all have been having a problem with crashing after someone logs onto my network server, which is still running the 10.4 Tiger version of the Apple server. They run fine if you boot up and log on as a local user, and they seem to run fine when you boot up and log on to with a server account, but when you log off from the server, about five seconds later while the aurora screen is still showing, they crash and give you the Apple version of the "blue screen of death."
I was told that the fix was to download the combo update separately from the Apple website and use that to reinstall and update the operating system.
I downloaded and tried installing with a 10.5.6.dmg file and a 10.5.6.dmg.smi file, but they both crashed.
Where can I find the "fixed" version of this update or is there some other fix?
I have tested this on 9 or 10 different systems.
The first file was MacOSXUpdCombo10.5.6.dmg, which is a disk image file that is 668.8 MB or 684,774 KB.
I looked in the discussion groups on the Apple web site and found some discussions for problems that seemed similar to, but not quite the same as my own. They led me to a file MacOSXUpdCombo10.5.6.dmg.smi, which a self mounting image file that is also 668.8 MB. I tried it and got the same result.
I can install my dvd, which gives me 10.5.1, which will log off and reboot correctly.
I can then install several miscellaneous upgrades:
Pro Apps Update 2006-02 V1.0
AirPort Utility V5.3.2
Remote Desktop Client V3.2.2
QuickTime V7.6
iTunes V8.0.2
and also
Front Row V2.1.6
The system will then log onto the network, log off and reboot correctly.
But, when I install the 10.5.6 combo update from any of my sources, it boots and logs on fine. But, if I log onto the network, it crashes when I log off.
Where do I go from here?
Thanks for your help.

Have you tried starting up with your install disk and doing a disk repair?
Put the install disk that came with the Mac in the DVD/CD drive and restart holding down the 'C' key. You can take your finger off once you hear it making noises from the DVD/CD drive. You'll be presented with a screen where you choose your language. At the next screen on the menu bar select Utilities>Disk Utility you then select your Macintosh HD on the left and click on 'repair disk'. If it makes any changes click on 'repair disk' again and repeat the process until you get a clean pass. Once done select restart from the Apple menu and hopefully the Mac will boot normally.

Turning iMac G4 into AirPort base

I have a 15" G4 iMac with a 800mhz processor. I just bought my daughter a 14" iBook that has an AirPort card. I've heard that I can install an AirPort card into my iMac and send my internet connection wirelessly to the iBook basically using the iMac as an AirPort base. Is this true and if so, what card to I have to have and does it matter that I'm on a dial-up connection (not by choice).

A dial-up connection should work just fine. The secret is to go into the Sharing System Preference pane and turn on Internet Sharing. There are two options:
1. Put an Airport card in the iMac and specify that you want to share your dial-up connection to computers using Airport. According to this page, your iMac uses the old non-Extreme Airport card. These can be hard to find and pricey if you can find one.
2. Get an Airport Express base station, connect it to the iMac's Ethernet port, and specify that you want to share your dial-up connection to computers using Ethernet. You'll have the additional step of setting up the Express as an Ethernet-to-wireless bridge. This will give you a faster wireless connection than the first option and may actually be cheaper than an Airport card.
Alternately, you could get an Airport Extreme base station. It has a built-in modem, so you could use it to dial into your ISP and connect the iMac to the Extreme's LAN port as well as connect the iBook wirelessly. The advantage to this approach is that it doesn't require the iMac to be turned on in order to access the Internet with the iBook.

Display To Match aluminum iMac

Hi there, my first post on here
I have a 24" aluminum iMac, i would like to have a second display. I would like to find a monitor that looks just like the iMac. Does anyone know of one that exists please?
Failing that i will use a cinema display.
Thanks for you time

Your iMac has a Mini-DVI port at the back to connect a second monitor.
Depending upon which Display you settle on you will need either a *Mini-DVI to DVI adaptor* or a *Mini-DVI to VGA adaptor* -

Any monitor you get will come with its own signal cable. The adaptor fits between the iMac and the Display's signal cable (i.e. iMac - adaptor - signal cable - display).
When you connect it all up and boot up the iMac, the second display will be detected automatically. You then need to go into +System Preferences/Displays+ where you will find a new option has appeared called 'Arrangement'. Open 'Arrangement' to -
a) *deselect 'Mirror'* if you want an +extended desktop+ (unlikely you will want the same display on both screens unless you do a lot of presentations), and
b) drag the diagram representing your second display to a position in relation to your iMac's own screen to match the actual physical position of your second display. (my second display is to the right of my iMac so the blue box representing my second display needed to be to the right of the iMac box).
A piece of cake.
Hope this helps
PS. My second screen is a different aspect ratio to the iMac display so, in Arrangment, it was easy to tell which blue rectangle represented which screen. If your new screen has the same aspect ration as your iMac screen they will look the same. I suspect the blue rectangle that represents your new second display will initially be the right hand one (just guessing though). You will soon work out which is which however.
PPS. Here's a suggestion (or three) for a display -
