Airport performance poor on Dual-Core G5. Solution?

I got my new G5 a few weeks ago with the Airport/Bluetooth card installed and I've had extremely spotty wireless reception since I've been using it. The bars just constantly go up and down all day and sometimes I just get dropped completely. I have 2 other computers in the room, an older AGP G4 with an Airport card in it and I've brought my old iBook in as well, all three with the same version of OSX installed, all updated completely. The two older computers get full signal strength at all times in the same room as the G5. From what I've read on the discussions, it seems the likely culprit is the internal airport antennae just not getting the signal strong enough, which seems to make sense since the other two computers recieve the signal perfectly. I don't have the option of moving the router into the room or get it closer to the computers, so that is out.
I suppose my question is, am I right in assuming it is a hardware thing with the airport in the new G5? And if so, is it something that should be addressed by apple and somehow resolved by them? Or am i most likely forced to buy some kind of bridge or airport express deal to bring in a closer signal. It seems kind of a bummer to have to keep buying new equipment to get something to work when i shouldn't have to, especially after spending so much money on the new G5 in the first place.
Any thought? Thanks!

I'll trade you my D-Link G122 USB adapter for your internal airport/bluetooth card .
See this link for further configuration details:
http://discussions.apple.com/message.jspa?messageID=595912#595912
The D-link configuration, while not as nicely integrated as airport, has a very strong signal, comes with an external USB dock (almost like an ipod dock) that allows for best antenna placement. At around $30, it is worth trying.
But if it works with your layout, I would probably recommend that you just use ethernet to tap into the G4 and then use it's airport connection to reach your router. When I tried this for my initial installation (using an old TiBook), it was more seamless than the D-link dongle.
Let me know if you want to take me up on the trade...I'll throw in a bluetooth dongle as well.

How to Install Airport Extreme on G5 Dual Core

There's no installation instructions included in the Airport Extreme card and it referred to the manual that came with the computer (in my case G5) but it's nowhere in the G5's manual. Do I install the software first then the card? I haven't opened my G5 yet but where exactly do I put the card in?

The software is already installed so don't worry about that.

Dual core vs quad core and nvidia vs ati

I'm curious to hear opinions and experiences from both sides...i'm considering purchasing an iMac w/ a quad core and I want to know more about how it performs against a dual core in these areas: Second Life, DVD burning, iMovie, iTunes, Toast, GIMP, Audacity, etc...
I would appreciate any input on this topic...thanks so much!!!

Sorry, yes it will suffice? if so how many years would I expect this computer to last me? (Sorry I'm really new to apple)

G5 Dual Core Powermac says no card detected

Hi All
It's been a frustrating day - first off I carted my mac 30 miles to an Apple Centre and waited for a long time whilst they installed an Airport Extreme Card with Bluetooth into My brand new G5 2Ghz Powermac (Dual Core).
Got the machine home and it turns out that they re installed the RAM incorrectly and after half an hour or so I sorted that.
I turn on the machine and try to detect the Airport Card and it says "no card is installed' The card is installed but it just doesn't work.
I can't get back to the store until next week and I was wondering if anyone had any ideas on what may be wrong. It looks like the antenna is connected and everything seems secure.
Help anyone please.

You might want to read the thread Airport Card & the new Dual Core Powermac's.
Otherwise your choices are:
Card is not installed correctly.
Card is defective.
Motherboard of G5 is defective.

Poor data rates with new G5 Dual Core & factory installed Airport Extreeme

I have finished porting over data from my G4/500mHz to my new G5/2.3. Placing the G4 off line and using the new G5 has me disturbed regarding the wireless performance.
I first noticed that the signal strength indicators on the G4 and the G5 never matched - the G5 was always lower. On boot the G5 wireless signal came on strong then faded to a single dot. I did the CNET cable modem test and it came up at 58k/sec!!!!!
I have been testing this all day. I now have my wifes IBM laptop running the same test and I get 1.5mb/sec. The old G4 agrees with the IBM at 1.5mb/sec.
I swapped out the Linksys with an old B model and the results are the same.
Is any one else seeing this happen??
G5 Dual Core 2.3 gHz factory Extreem card Mac OS X (10.4.3) Linksys54G and Comcast cable

Actually, I think the problem may be were the antenna is located on the Dual Core G5. On previous versions, the antenna was external, you could even add a higher gain antenna if needed. The new dual core and quad have the antenna internal to the machine, and I think this is probably why your G5 is showing a low signal strength.
I would imagine two possible fixes for you, assuming you want to stay with a wireless connection.
First, an external antenna. You would need to find out the type of antenna connector used on the Airport Extreme/Bluetooth card internal to your G5, then buy an external antenna with the same type of mating connector on its cable.
The second option would be to add either a USB Wireless adaptor, or an Ethernet wireless bridge. Either would provide you with a better wireless connection and the ability to move the antenna around to get the best reception.
The third (you knew there would be a third, right?) is to connect via standard Ethernet. Much faster and much more stable, though you will need to run cable.

AirPort Extreme with Bluetooth 2.0+EDR Card for Apple Dual Core

Hello everybody,
Where can I buy the AirPort Extreme with Bluetooth 2.0+EDR card for a new Apple PowerMac G5 2.3 Dual core? What websites or locations in Los Angeles sell this card?
What workarounds are out there?
Thank you all for your answers.
Apple G5 Dual Core Mac OS X (10.4.3) HD Cinema Screen

The new Dual Core G5 machines do indeed come shipped in the base models without Bluetooth or Airport Extreme. There will be a solution available through the local ASP's (Apple Service Providers) and Apple Genius bars in the Apple owned Retail stores. Many of the store employees are not fully aware of the situation, however, they should be able to look up the issue in the Knowledge Base.
There is a service part (PN 661-3692), that should likely be available for future upgrades. At present, the part is constrained, and therefore restricted to exchange only repairs. You may want to contact a service provider or Apple Retail location to inquire on availability as an upgrade part, as it is currently not planned as a DIY (do it yourself) activity and would have to be obtained and installed by one of these service providers.

I'm getting poor performance from my apple TV, will plugging in my airport express via ethernet to apple tv increase its performance (poor wi-fi signal)

Yes, though it is less ideal than what I suggested earlier. You would need to place your AirPort Express in a location approximately midway between your AirPort Extreme Base Station and the TV. Then, using AirPort Utility, configure it to "extend a wireless network".
It may help. Bear in mind the signal thus "extended" by the Express can only be as good as the signal it can receive from the Extreme. That is the reason for selecting its appoximate midway location.
Read about it here: http://support.apple.com/kb/HT4145
Scroll down to "Wirelessly Extended Network (802.11n)" for a picture.
This solution requires an all-Apple wireless network. No third party stuff.
You mentioned using Ethernet. That would be a better idea. Scroll down to "Roaming Network (Ethernet-connected Wi-Fi base stations)" for a picture. In your case, the longer the Ethernet cable - hence the closer you can move the Express to the TV - the better

Jdeveloper dual core processor performance problem

I have a dual core 2.4 ghz processor and 2 gig of ram and Im running Jdevloper 9.0.5.2 and my performace is terrible. Other developers in the company have non-dual core processors and they can start up in debug mode using the Jdeveloper embedded oc4j our application in 10 seconds where it takes me 4 min!!!!! It is a struts,ejb web application. Is there anything I can do to help in debug mode??? cheers.

Hi Bernard,
Which version of McAfee are you using?
On my (personal) laptop, I'm using McAfee VirusScan 9.0.10. I don't frequently run JDeveloper on this laptop, but when I do, it's not experiencing signficant startup delays (it's a very low power machine: PIII 650 512Mb)
McAfee VirusScan seems to have very few configuration options (noticably different from Norton, which I use on my corporate desktop machine). I specifically remember changing the "File Types to Scan" option to "Program files and documents only". You can get to this by right clicking the "M" notification area icon, VirusScan->Options menu, Advanced button on the ActiveShield page.
In Norton, I think I have it configured so that it only scans files on write rather than on read. I also exclude directories which contain jdeveloper installs or other large Java apps (although scanning only on write elliminates most of the performance problems anyway and still leaves your system reasonably secure).
The easiest way to convince your MIS dept that the virus checker is the source of your problems might be if you ask them to allow you to turn it off in order to test the difference it makes to performance. It's a reasonable request to make if you're trying to elliminate possible causes for the slowdown (from the description you gave, it does sound like the AV upgrade is the first place I'd start looking).
If the virus checker is the source of your problems, you'll probably be seeing massive slowness in most large Java applications that have a large number of JARs on their classpath.
Thanks,
Brian

LE 9.0 performance on Mac Mini (dual core) Vs. iMac (quad core)

I am in the process of evaluating options to replace my 2007 MBP with a faster DAW. I am on a budget so while I am looking for performance improvements over what I have, I don't need overkill either. I am considering the 2011 Mac Mini (2.5 GHz, dual core) and the 2011 iMac (2.5 GHz quad - core). Whichever configuration I choose, I will bump up RAM to 8 GB.
I use LE 9.0 and a Presonus Firestudio Project and would like to know whether what kind of performance improvements I will see between the two options I am considering. I use a lot of plugins, and an external Firewire 800 drive for recording. Obviously with the Mini, I will have to buy an optical drive as well. I already have two monitors, keyboard and mouse.
The only thing that worries me about the Mac Mini is the slower 5400 rpm hard drive. While I plan on using an external drive for recording, I am concerned because of the number of plugins and sample files that need to load during recording / playback.

My 2011 intel dual core duo iMac apparently has "Airport" ans apparently it is "on" although the icon (upper right) is gray. I'm not sure what "airport" is

My 2011 intel dual core duo iMac apparently has "Airport" ans apparently it is "on" although the icon (upper right) is gray. When I click on the <gray> airport icon it says it's "on" and the option is to turn it off.
I'm not sure what "airport" is, and I have no idea what a router is supposed to accomplish. I got a "smartphone" (not an iPhone, an android) and at a "Smartphone class" at the senior center I was told I need a router.

OK, so, in installing a router could I attach the router to my Verizon DSL modem and have the iMac get it's internet from the router by wi-fi?
This way I could place the router 1/2 way between the only two places in my home where wifi devices (wife's tablet, my iMac) are.
Yes, exactly.
For the router I suggest you consider one of the three Apple AirPort Base Stations, not only because it will be easier to get help with using them on this website, but they are generally regarded as the most reliable wireless routers. Technical support directly from Apple is free for the first 90 days.
Slightly cheaper alternatives exist. I have tried other manufacturer's wireless routers, and I don't recommend them.

Older SP vs. Dual Core - Browser/Plugin Performance

Hi Gang
Have been down the block here many times. I'm very familiar with issues regarding the discontinued support of Flash Players and the frustration trying to keep your perfectly good running older G5's up to date.
Have question why I can't get the browsers in my older G5 SP 1.8 to work as satisfactorily with my two Dual Core G5's?
Details: I have 3 G5's #2 Dual Core 2.0's and #1 older SP 1.8. The Dual Core machines have #2 Browsers installed; TenFourFox ver 4, & Safari 4.1.3 with Flash Player ver 10.0 r45. Most videos in BOTH machines play just fine including UTube.
However my older 1.8 SP machine, (with browsers Safari 4.1.3, & TenFourFox ver 9), trying ALL archived versions of Flash DO NOT function properly. Each time I've used the Adobe uninstaller, then tried several/all archived players, always followed by 'Disk Permissions'. NONE will yield the same satisfactory results as with the Dual Core machines.
I'm wondering now if this situation could be related to the older 1.8 SP? Or perhaps have something to do with the Video Card in the SP machine? It's the only machine with an ATI, rather than Nvidia?
BTW, I also just tried a 'home-made altered' version of Flash, which was created by a skilled-creative person who's efforts are directed to us G5 users with NON-Intel machines. Anyway, it also failed ...
Any ideas?
Thanx
Mike

Mike-
Your video plays fairly well on Leopard in Safari (Flash 10.1) in my 2.0 GHz SP G4 w/Geforce 6800 GT.
With scaling on and full screen, the video is jerky. With scaling off, the video smooths and the video is enjoyable to watch.
HOWEVER, comparing the playback of the video on an Intel processor machine with much stronger CPU/GPU and Flash 11.1, the playback quality difference is marked; cinema-like as opposed to "web video"....
It's the only machine with an ATI, rather than Nvidia?
In your case, you have adequate GPU but inadequate CPU.
The 1.8 GHz machine wasn't good for more than 20-25 fps with HD at 480i.
128 MB VRAM and a mid grade GPU (9800 and better) are all that are needed in the graphics department.
One needs 30 fps and better to "see" smooth video.
If you were complaining about video with a FX 5200 or a Radeon 9600 I would say "get a better card".
In this case, No.
Video in OS X has ALWAYS been far more CPU bound than GPU bound... some comparisons to Windows put the diference at 5x more CPU.
BTW, Radeon drivers have, historically, almost always been better than Geforce drivers in OS X.
This is especially true in Tiger and Leopard.
I'm wondering now if this situation could be related to the older 1.8 SP?
Yes.
You are simply experiencing the limitations of the SP 1.8....... NO comparison AT ALL to either of your dual core machines, regardless of the graphics card.

Old macbook air dual core 1.4 or 1.6 VS Mac Os X Lion performance

what are your experience using Mac os X Lion with old mac book air ( dual core 1.4 or 1.6 )

thanks for that info guys. I will download the 10.7.2 update and see if that fixes it.
regarding booting into safe mode: I haven't tried that but I am able to boot the computer up normally after the crash. It's just annoying that I have to reboot it at all.

Windows Vista 64 bit w/older 2 dual core 3.0ghz Mac Pro with NVIDIA 7300

I have read a variety of the posts that have appeared here on the use of Windows Vista 64 bits on a Mac Pro. I remain confused, and but want to do this. I have a Mac Pro purchased in the Spring of '07 with dual 3.0Ghz dual core Xeon cpus and 10gb of ram, using the NVIDIA GeForce 7300 GT and running 10.5.1, with multiple drives. I want to run the 64 bit version of Vista Ultimate to use my ram, and to gain the performance this box should offer. It appears that I have three options:
1. Boot Camp: I don't know if the drivers are available, seems like the new Mac Pro drivers probably would not work, even if I could find them, since I have an older Mac Pro with a pair of the dual core Xeon CPUs. Don't know if there is an alternate source than Apple for the drivers, or a way to get around the problem in boot camp.
2. Parallels: I do not believe that 64 bit apps are supported by Parallels
3. Fusion: Their web site says they support Win Vista 64 bit, but it is not clear to me on the web site where the drivers are obtained, or perhaps they are built in to Fusion. Will I get the performance and memory benefits in fusion? Or is the OSX virtual overhead so high that this is a fools errand?
I do a lot of video editing, and fully 95% of my life is in the Mac world, but I have individuals who send files for editing, and occasionally they require Windows tools, much to my chagrin. I also have a small number of programs that need Windows 64. I occasionally am required to do some development work, and would like to use this machine for that purpose if it can indeed run Win Vista 64bit. I have XP loaded on a more modest box andit is running fine when I need it, which isn't very often.
Any help, or successful experience in running Windows Ultimate 64 bit on this hardware, utilizing its resources would be greatly appreciated.

Here are my results after further digging online and from my own experience.
Here is the procedure:
1. Check whether your Mac has the 32-bit EFI or 64-bit EFI
http://www.ihackintosh.com/2009/08/snow-leopard-106-and-64-bit-what-you-need-to- know/
2. Create a Boot Camp (BC) partition for Windows 7 x64. Resize the partition size using the slider in the BC app. Follow the instruction, insert the Windows 7 disk and reboot.
3. This will load the PC partition which is FAT formatted for now. Choose the Boot Camp partition on which to install Win 7, but choose in the option to format that partition. It will automatically format it in NTFS. Otherwise, it will not install on that partition.
Note : A "OEM System Builder" Windows 7 64-bit Professional UPGRADE install without any issues what so ever. The upgrade disk is a full install. Read this for further information:
http://www.pcworld.com/article/174288/windows7_upgrade_madecheaper.html
4. Run windows, then insert the Snow Leopard disk. It will tell you your hardware cannot support x64 version. Do the following procedure to manually install the driver:

5. Then update Boot camp using Apple Software Update in Windows.
6. All hardware works fine except the sound. The sound only comes out of the internal speaker, even when headphone or speakers are plugged in the jack. Installing the Realtek High Definition Audio Codecs driver in order to fixe the problem. Shutdown and reboot to make it applicable. Try a second time if it still does not work:

Audigy2 NX USB on dual-core system - crackling + skipp

I have an Audigy 2 NX (USB) SoundBlaster which was working perfectly until I upgraded to a dual-core Athlon X2 4200+. Now I get not just crackling, but skipping - MP3s play at 2-3 times the normal speed, missing out big chunks. I'm using USB 2.0. It's definitely not a problem with the USB controller on the motherboard because I get the same if I plug it into an Adaptec PCI USB controller.
Some observations:
) Disabling USB 2.0 support in the BIOS (falling back to USB .) doesn't fix it.
2) The skipping only happens for applications using WinMM. DirectSound is fine. This suggests the USB is OK but the Audigy drivers are somehow confused by the multiprocessor setup. I tested this using WinAmp with waveOut / DirectSound output.
I'm guessing Creative needs to add multiprocessor support to their drivers.Message Edited by mjarga on -28-2005 08:46 AM

I did find a solution - but it sucks.
. Uninstall your Audigy NX drivers
2. Disable USB 2.0 support in your BIOS
3. Reinstall the drivers from the original CD (not the new ones from the website).
Creative tech support were not very helpful:
"What it sounds like is that you may be having a bus issue between
Windows and your Computer
What I suggest is trying the SID656 This should help with the issue."
Eventually found out that SID656 is a knowledge base article on tuning your PCI card's performance. Great.
