New Aluminium MACBOOK - Airport Extreme adapter very high pitch scream! Oww

I have just connected my Netgear Wi Fi router to my PCin order to get the internet on my Brand new MACBOOK. Unbelieveably I found this very easy once I had the necessary kit but to my dismay the Airport Extreme adapter on the the MACBOOK has started to scream at me in a way that is almost unbearable to listen to. The noise is that of a sinclaire spectrum loading but at a very high pitch so it pierces the ear drum! I am currently sitting with my finger in one ear to try to protect my brain from the savagery. Does anyone else have the same problem? none of my other Wi Fi adapters sound like this, is there anything I can do to stop this?
Please Help

If anyone's interested, this seemed to have to do with WPA-PSK encryption. Turning it off seemed to work. Don't want to run unencrypted, so I'm using the Netgear USB dongle thingie instead of the airport card for now.

Migrate from minimac (G4) to new iMac via airport extreme

I have a brand new iMac and I have the latest airport extreme.
I have my old miniMac and all are linked up through the Airport Extreme.
I want to transfer all of my old files from my G4 miniMac to my new iMac but the Migration Assistant says I have to use (buy) a firewire cable.
How do I transfer my files from my old computer (miniMac) to the new iMac via airport extreme?

sorry to say but its the firewire technique which Migration Asst. uses. It does not migrate over Ethernet.. its actually very simple...
you put your G4 into target disk mode. You put the iMac into migration asst., attach the cable and the migration (file copying) begins after you chose to proceed.
The reality is firewire is faster than most standard ethernet anyway... and wireless? it would take an extraordinary amount of time.

Buzzing noise during wireless data transfers from new (model 1408) AirPort Extreme.

I exchanged a 3 week old 4th generation AEBS to get this new allegedly more powerful 5th generation AEBS. Both base stations were positioned in identical locations adjacent to identical harware. Yet only the new model emits the buzzing sounds. Any explanations?

Additional information gathered since original post...
At this point I have purchased and have had the opportunity to use 3 new 5th generation AirPort Extreme Base stations (model 1408). Two came from my local Apple retail store and the third was shipped from the on line store. All three emitted exactly the same buzzing/hissing noise during network traffic. I sit about 2 feet from the AEBS in a quiet home office and these sounds are very annoying.
Two Apple tech support reps claimed they never heard of this problem. I directed them to Apple Support Community postings dating back to 2009 that exactly described this issue (even with the 4th generation AEBS). Although these posts were detailed, as far as I could tell they did not state that Apple provided an explanation. My calls to Tech support have been kicked up to systems engineers. I am supposed to get some sort of reply after July 4.
I think others should make Apple aware of this issue (again) if their AEBS routers make the same noises.
Thanks

Very high pitch sound on new Quad

Just got my Quad yesterday
Everything is good, except that it has a very high pitch sound that is very annoying and it hurts my ears in the long run.
I disconnected the HD and superdrive to see if I could locate the source, but it is still there.
I thought about pulling the gpu (6600 256MB), but I don't know if the Quad will start up without a gpu.
I thought the 6600 was supposed to be with a fan, but all I see is black cooling ribs.
Any others with this sound ?
Its not a fan noise, and not a pump noise. It is like a 'electronic' whine.

I have sensitive hearing and noticed something similar when I got my 2.5GHz liquid-cooled G5. It was a constant sound and believe it was coming from the cooling pump. Does your sound ever vary? Try running System Load and see if you can get it to vary.

V. Slow transfer speeds with new dual band Airport Extreme

I have a new Airport Extreme (late 2009, dual band, full 'N' spec) which I am using to replace an older Airport Extreme (early 2008, 5Ghz, 'draft' N).
I have a USB disk attached and was interested in benchmarking the transfer speed of the new Extreme, compared to the previous version. The results are puzzling / alarming.
Shown below are transfer speeds (file copied to the attached USB drive) under different connection standards (2.4Ghz / 5Ghz & a/b/g/n)
'Old' Airport Extreme
5Ghz - 'draft' N : ~5-7 Mb/sec
'New' Airport Extreme
2.4Ghz - b/g : ~3-5 Mb/sec
5.0Ghz - a : ~3-7 Mb/sec
5.0Ghz - N : ~200 Kb/sec
Hence transfer speeds appear to collapse when I try to make use of the 'N' spec with the latest Extreme. I have tried altering items such as - wide channels (on / off), interference robustness (on / off), 5Ghz channel (manual, instead of auto), with no upside.
I seem to be at the point of concluding that either
1. I have a 'broken' Airport Extreme
2. The WiFi card on my early 2008 iMac (which implements I guess the 'draft' N standard) is 'incompatible' with new the Airport Extreme under a 'N' connection.
Any thoughts ?

Since all devices in my wireless network are capable of latest 802.11n protocol, I really do not need older and slower 802.11a/b/g protocols. To achieve above 200 Mbit/sec, 5GHz band with wide channel option turned on is really necessary. Thus I really wish I can turn off the 2.4GHz radio band (seems Apple has set this band as default) of my new dual band Airport Extreme to avoid unwanted bandwidth degradation. Unfortunately this is not possible with radio mode setting in Airport Utility.
The best I can do to force connection with 5GHz radio band (with quite consistent result) is as follows:
On Airport Extreme through [Airport Utility>Wireless] :
Radio Mode: 802.11n only (5Ghz) - 802.11b/g/n
More Options>Wireless Network Option>Transmit Power: 100%
More Options>Wireless Network Option>Use Wide Channels: checked
More Options>Wireless Network Option>5 GHz Network Name:
checked and same network name with extra suffix "(5 GHz)"
On 27" iMac through [System Preferences>Network>AirPort>Advanced>AirPort]:
Preferred Networks:
Create only one profile in Preferred Networks for the above network name with suffix "(5GHz)"
Uncheck the option [Remember networks this computer has joined] to ensure there is only one profile under Preferred Networks .
Once all above settings are done, restart Airport Extreme in Airport Utility. Your computer should connect wirelessly to the base station through 5GHz band after booting most of the time. Even when it is not occasionally, simply go to the Airport icon in main menu bar and click on the network name with suffix "(5GHz)" in dropped-down list to connect manually. With all these settings, I have achieved 300 Mbit/sec bandwidth on my iMac most of the time for fast Time Machine backup.
How I wish feature for better radio mode control by end user will be implemented in next update of Airport Utility. Apple should trust end user's brain better than artificial intelligence (or ignorance ?) in wireless network implementation. Wireless traffic between the two radio bands and among various wireless devices should be segregated specifically in Airport Utility by end users whenever dual band Airport base stations are in use.

We recently switched ISPs. To connect to the new ISP our Airport Extreme has to be in bridge mode. Now our Nintendo Wii won't connect to the Airport. Is it an issue with bridge mode that is causing this?

We recently switched ISPs. To connect to the new ISP our Airport Extreme has to be in bridge mode. Now our Nintendo Wii won't connect to the Airport. Is it an issue with bridge mode that is causing this? We're running two Macs wirelessly with no problems. And the Wii did connect before the switch.

Hello and thanks for the reply. I gave this a try, turned off Airport on one of the computers and tried the Wii again. Still no connection. I should say that we're also running an old G4 (wired) off the Airport as well, with no problems. I've tried many things to make the Wii to work, including power cycling the Airport, turning off the security settings in the Airport, resetting the Airport to it's default and redoing the network, resetting the network setting on the Wii (several times), moved the Airport closer to the Wii, all with no luck. The Wii "sees" the Airport but won't connect to it. I'm at a loss for anything else to try, so any help is appreciated.

ASA5505 emits a very high pitched noise

We just got a new 5505 1 week ago. Upon plugging it in it has a very high pitched noise. Similar to the sound you get when your ears are ringing or a cricket but its constant.
This drives us nuts. Any ideas what it can be since there's no fan or moving parts I can't figure it out.

sounds like the switch mode power supply isn't running fully.
does it do it if you just plug the PSU in but don't connect it to the ASA? or is it just under load of the ASA being connected?
either way id put in for a replacement as its not good

Power Mac G4 MDD 1.25GHz DP often completely locks up in the first few minutes after booting, sometimes with the spinning beach ball, normally with a very high pitched whining noise.

Over the last few months my Mac has developed a worrying habit.
Within the first few minutes of starting it up (perhaps on average about 50% of the time) it will completely lock up. This may happen at the Log In screen (if I start up the Mac & then leave it for a while) or during normal use.
Often the first symptom is a very high pitched (but quiet) whining noise that seems to come from the loud speaker on the front of the Mac. The pointer may freeze at this point, or it may still be moveable for 5 or 10 seconds before it freezes. It sometimes turns into the spinning beach ball during this. Once locked up the only way I can restart the Mac is to hold down the power button on the front for a few seconds to completely reboot the machine.
Once the Mac has restarted, it usually behaves normally, almost always for the rest of the day. The initial lock up & resulting restart only normally seem to happen the first time I use the Mac that day.
The only peripherals attached to the Mac (apart from the display, keyboard & mouse) are an ADSL modem, a USB printer and a pair of Apple Pro speakers, and this setup hasn't changed since long before the problems started, so I'm confident that I can discount the peripherals causing problems. I doubt that unplugging the speakers, for example, would have any effect.
I've run Disc Utility, OnyX and DiscWarrior without anything major cropping up. My instincts (I've been troubleshooting Mac problems for 16 years) tell me that I have a fundamental hardware problem, possibly with one of the 4 RAM DIMMs installed.
The RAM configuration is shown in the attached screen grab.
I'm considering removing one DIMM, running with 1.5GB of RAM rather than 2GB for a while, and repeating with a different DIMM removed each time until I can hopefully isolate the dodgy DIMM.
Do people feel this is a sensible approach, or should I try something else first?
Many thanks.

Sometimes visual inpection will show bulging tops/sides., my guess is if it is it's most likely in the PSU.
Possible cheap fix, You can convert an ATX PSU for use on a G4...

G5 Dual 2.5GHz freezes with a very high pitch sound

Hi
My G5 Dual 2.5GHz freezes with a very high pitch sound from inside the comp. It happens occasionally after a few days of everything running smoothly. Someone can help ?
PowerMac G5 Dual 2.5 GHz Mac OS X (10.4.9)

Hi Phil Brayshaw-
What does the little white power light do? This should be helpful: About the Power Mac G5 (Late 2005) diagnostic LEDs
Although it sounds to me like you have tried most of the troubleshooting steps, this document is a good overall reference to address this particular problem: Power Mac G5: What to do if you see black, white, or no video at start up
Have you tried another monitor and/or double-checked your cable and its connections? If everything else is working as expected that would certainly be a major suspect.

New airport extreme network very slow

I just bought the latest AE base station dual band, but am having trouble with the speeds. We have on the network:
1 macbook pro, 1 windows pc, 2 ipads, 1 ipad mini, 1 kindle fire, 2 iphones, 2 ipods (wow we have a lot of products I just realized now that I am writing them all down) a Wii console and 1 mac desktop computer. Oh and I have an airport express in another room set up to extend the netowrk.
Not all of them are on the network simultaneously.
Using the Airport utility (windows version) I have set up the network trying different configurations. Currently I have it set up as:
Radio mode: automatic
Radio channel selection: automatic
wireless security: WPA2 Personal
network options are 5 Ghz is unchecked
country is US
multicast rate: low
transmit power: 100%
WPA Group Key Timeout: 2 hours
use wide channels is checked
All devices can connect to the net, but speeds are at old dial up levels and that of course was NOT my intention in getting the latest router.
Any advice from those who understand things like multicast rate?

You either have a defective base station, it is not set up properly, or there is some form of Wi-Fi interference that is preventing your new AirPort Extreme from providing a clean signal.
What make & model was the router that you are replacing with the 802.11ac AirPort Extreme?

New Macbook airport extreme will be disconnected sometimes

I bought my new macbook several days ago, but I found the airport extreme always disconnected several minutes, why? I call my friends via skype, but sometimes the call will be disconnected! who can tell me why?

I have the same problem and I am not alone. My old PowerBook Ti has no problems but my MacBook drops connections even when 5 ft from the router.

Setting up network with newer and older AirPort Extremes

Okay, I thought this was going to be so simple. I have a newer (like a year old - square) Airport Extreme that I have three computers wirelessly hooked up to in the house. Great... so now, I want to hook up the old iMac in my son's room that doesn't have a wireless card to the network. It is too far away to use the ethernet cable into the back of my newer Airport Extreme station so I figured I'd dust off the old saucer type base station, plug the ethernet cable into that in my son's room and then just easily get the old base station to network with the newer one wirelessly.
Not so easy. The newer one has no reference how to make a network with other base stations whatsoever and the old book describes how to with the Airport Admin Utility which is not available to the newer version, just Airport Utility and it does not have the WDA options listed. I tried to extend the network and then Doh! The whole network disappeared.
Is this a compatibility issue with the older and newer base stations? Would it just be easier to put in a wireless card to my very old iMac, if that's even possible? Has anyone successfully networked an old and new base station together? If so how?
Thanks!

Welcome to the discussions!
When you have an older "g" device (the flying saucer) and a newer "n" device (the square one) in order for them to communicate using wireless only, you must configure both of them in what is known as WDS configuration.
This is a quite tricky setup for most users. The best set of instructions that I've seen for this comes from expert user Tesserax in this thread:
http://discussions.apple.com/thread.jspa?threadID=2355832&tstart=0
If you elect to try this type of setup, you will probably need to hold down the option key on your Mac while you click on the Wireless Mode selection box to get the WDS option to appear. (My guess here is that Apple "hides" it because it slows down the network substantially). But, it's the only way to do what you want to accomplish with and old and new device.
Other options would include the wireless card you mentioned for the iMac. Even better might be a pair of ethernet powerline adapters. One adapter goes near the AirPort Extreme and the other near the iMac. The AC wiring in your home transmits the ethernet signal of the powerline. Works great, almost no configuration required and better than wireless in many cases.

Problem consistently printing via new (summer 2011) AIRPORT EXTREME BASE STATION and Brother wireless printer (model HL5370DW). What am I doing wrong?

Thanks in advance for any help you folks can offer. I'm a newb here and will try to offer as much detail as I can about the dilemma at hand.
Scenario: Home network has been recently set up for wireless internet access via NEW Airport Extreme Base Station (purchased September 2011). Units accessing the network include: 2011 Macbook Pro, 2011 Macbook Air, 2007 Macbook, 2009 Macbook Pro, 2 iPhone 3GSs, and a 1st-gen iPad (and a partridge in a pear tree AEBS is configured to run WPA2 encrypted network, as well as a WPA2 guest network. I am attempting to yoke a BROTHER HL5370DW wireless B or G/ ethernet / usb-capable printer to the main network such that any and all units can print wirelessly or its equivalent (i.e., via printer hooked to AEBS through USB hub)
Problem: Despite configuring the Brother printer to recognize the main WPA2 network I created, I am unable to get wireless printing to work. My workaround was to physically connect Brother printer to AEBS via USB, specifically using a Belkin USB hub (after all, I wanted access to usb drives, as well as the printer). This workaround works ONLY SOME OF THE TIME. Generally, after a fresh boot of any computer or after a restart of the AEBS, any given computer will be able to print (i.e., any computer wirelessly connected to the main WPA2 network recognizes the printer). HOWEVER, at random times, printer access is gone (as is access to USB drives connected to AEBS's usb hub). Wireless networks are still up and running when that happens. IS THERE A WAY TO GET THE USB HUB's devices (i.e., printer and usb drives) to ALWAYS REMAIN AVAILABLE AS LONG AS THEY STAY CONNECTED TO THE AEBS? In other words, what accounts for the intermittent loss of the usb peripherals?
Sometimes, I just shut the airport off on whatever computer is having this problem, and the problem goes away. Sometimes, the problem is present across all computers in the house, sometimes only a few are affected. I can ALWAYS see the AEBS in the Airport Utility if the AEBS is connected to the particular computer via ETHERNET CABLE.
My theories:
- true wireless printing (i.e., without usb hub workaround) doesn't work because the N network somehow isn't backwards compatible with the Brother printer, which, i believe, is B/G. Although...isn't Wireless N networking supposed to work with BG devices? I did find a thread (https://discussions.apple.com/thread/2570774?start=0&tstart=0 ) that explains some of the particulars of WPA2 encryption and Wireless B/G issues, but it was beyond my level of comprehension (I'm a psychologist, but not an Apple Genius
- The usb workaround is only intermittently viable because of some flaw in the Airport or Airport Utility that causes dropouts to happen when a Macbook Pro or Air's lid gets closed or one gets opened after having been at a different network (e.g., at my office).
QUESTIONS:
- Should I try to use my old router (7 year old Linksys WRT54G) as an access point and connect the Brother printer to that G-router? How do I do that?
- I wouldn't mind just relying on the usb hub method if I could just insure more consistency (i.e., no random dropouts of peripherals). How could I do this?
Rule out:
- wireless printing works on my printer - it was being recognized back before the AEBS. I had the Linksys router running a WEP network and had the wireless printer talking with no cables to the router and the computers. (I just don't want to revert to using WEP encryption given its lack of security and my trying to protect HiPAA related health information on behalf of patients)
Any help will be greatly appreciated.
Thanks in advance!

13 ASCII characters = 104 (aka 128)-bit WEP
encryption
If turning off WEP works, then you just need to
provide the cameras with the "Equivalent Network Password".
One of the problems with WEP is that the actual
standard relies on a 10 character HEX key for 40bit
WEP and a 26 character HEX key for 128bit WEP.
In order to make things easier, vendors use certain
algorithms to convert simple alphanumeric passwords
(or passphrases) into HEX keys, thus enabling the use
of simple easy to remember WEP password rather than
lengthy HEX keys. The problem is that different
vendors use different algorithms to generate the HEX
key and therefore a ASCII password on an AEBS will be
hashed differently on a non-Apple client and vice
versa.
You may find the following article helpful:
- Apple article, especially the part about
"Third-party client to Airport".
Brilliant idea about trying the system with No encryption on... that DID solve the problem... almost.. once I turned off the encryption option, and restarted the Airport, I got a dialog box showing that the "Base station needs attention" but it didn't indicate WHAT kind of "assistance" it needed. Nonetheless, I closed out of the Airport program only to find that the indicator light, which had been Green, was now, flashing Yellow and I could not connect anything, including my computer. I opened the Airport program again and found the ONLY way I could get the Green light on was to select some sort of encryption option... then the light would go Green again but my cameras would not hook up again, and when I went back in and ONLY changed the option to NO encryption, I got the yellow flashing light and the "this base unit needs attention" warning...
I think your suggestions are almost on the mark... is there any way of reconciling the WEP coding between the cameras and the Airport??? Or turning off the encryption option and STILL have Airport work?
Thanks again for your help and suggestions... I really appreciate it.

Will Airport Express 802.11g network with a new Dual Band Airport Extreme?

Bob Timmons I need your help. I have a older Airport Express, can I use it to extend my wireless network to the far reaches of my house by linking it to my new Airport Extreme 802.11n?
There must be an article on this somewhere.
Thanks!

Welcome back!
If by "older" AirPort Express, you mean it is a "b/g" version, you'll have to use the WDS setup options on both the new AirPort Extreme"n" and the AirPort Express.
Unfortunately, two negative things will occur when you setup WDS:
1) Because WDS is a "g" technology thing, the entire wireless network will drop down to "g" wireless levels. So, you lose any advantages of "n" speeds with your new router.
2) The bandwidth on the entire wireless network will be cut 50%.
Bottom line, you will have a "g" wireless network operating at half of it's capability. That's a tremendous loss of performance for a bit more wireless coverage, but you may disagree.
WDS is difficult for most users to set up because it is very easy to make a mistake. Look over this post to get an idea of what is involved with this. There is also a link to Apple's instructions in this post, but the step by step by expert user Tesserax is easier to follow.
http://discussions.apple.com/thread.jspa?threadID=2287950&tstart=0
I do not recommend WDS, but it's your call.

New Mac and Airport Extreme Base Station User - Setup question

Good Morning,
I just received my new MacBook Pro yesterday along with the Airport Extreme Base Station. I was tying to setup the airport extreme but have had no luck. I want to make sure I'm connecting things correctly - make sure I'm not doing something stupid.
I have a cable modem and I previously had a Netgear router. The connection from the cable modem that had previously been connected to my Netgear router - I disconnected it and connected it to the Airport extreme base station instead. And then I plugged it in. Is that all the connecting that I need to do? I get the flashing amber light.
Now I did read a few other threads and it sounds like I may need to install the Airport Utility that came with the base station. So I'll try that when I get home tonight. But I would appreciate any other suggestions - especially whether or not I've connected the airport extreme correctly to my cable modem.
Thanks, Susan
MacBook Pro Mac OS X (10.4)

I want to make sure I'm connecting things correctly
The network configuration should look something like the following:
Cable modem > (Ethernet cable) > [WAN port] AEBSn > (wireless) > MacBook Pro
I have a cable modem and I previously had a Netgear router. The connection from the cable modem that had previously been connected to my Netgear router - I disconnected it and connected it to the Airport extreme base station instead. And then I plugged it in. Is that all the connecting that I need to do? I get the flashing amber light.
Since you changed your network configuration, you should perform a complete power recycle of your network components to allow enough time for them to "synchronize."
Modem/Router Power ReCycling
- Power-off the Cable modem, AirPort Extreme Base Station (AEBSn), & computer(s). (Wait at least 30 minutes. If possible, leave the modem off overnight.)
- Power-on the Cable modem; Wait at least 30 minutes.
- Power-on the AEBSn; Wait at least 5 minutes.
- Power-on the computer(s)
Now I did read a few other threads and it sounds like I may need to install the Airport Utility that came with the base station.
Yes, you will need this utility to perform the setup and follow-on administration of the AEBSn.
