MacBook Pro Airport Performance

As discussed in two threads on the iMac Core Duo forum, the Airport implementation in the iMac seems to be hurting. Apple knows about this and there is a P1 level bug report filed. This means that it must be fixed before the next release.
The other threads are
http://discussions.apple.com/thread.jspa?threadID=339752&tstart=0
and
http://discussions.apple.com/thread.jspa?threadID=338281&tstart=25
There may be more than one problem, but the one described results in 3 easy to detect symptoms
1) download rates are about 57% of what one would expect
2) "ping" shows 6 good pings followed by 4 bad ones, then repeats
3) the network graph in Activity Monitor shows a "sawtooth" response when transferring large files. The sawthooth has a 10 second period (which cooresponds to the ping results)
Some more data can be found at
http://www.girr.org/macstuff/networkspeed.html
The purpose of the NEW thread on the old subject is to strip off the chaff of the long old threads and pose a simple question
"Does your iMac Core Duo behave this way?"
Some folks say that their systems are working fine, others have serious troubles. If some work fine, then it isn't software. There may be a batch of "bad" ones out there (of which I apparantly have one). If the vote comes back mixed, it is probabably a hardware issue that doesn't impact every piece of hardware. If the vote is consistent, then it could be either hardware or softare.
I've asked the MacBook Pro folks to join in so please indicate your hardware as well and ALSO reply to this thread:
http://discussions.apple.com/thread.jspa?threadID=380801&tstart=0
BTW, I've fired up an AXBS as a WDS remote and wired it to the iMac and now all is well

Mine works fine, and I actually am getting slightly BETTER throughput. No packetloss (which is likely the cause of your throughput issues).
I'm using a Linksys WRT54G with the OpenWRT firmware and my MBP.

HT1338 my macbook pro airport won't turn on! What would be the problem?

my macbook pro airport won't turn on! What would be the problem?
I've tried to turn the airport on and it says my airport card is not installed...
it has always worked till today... bot from now on nothing seem to help the airport work...
Please help me!
Thanks

You could try deleting the airpot from the sidebar of system preferences/network. To do this,
1) export the preferences for your airport to your desktop by pressing the gear next to the plus and minus sign above the lock.
2) Delete your airport from the sidebar using the minus sign while the airport is selected.
3) After deleting the airport, apply the changes and then press the plus sign to create a new airport.
4) Then import the preferences back in and apply the changes again.
This may bring your airport back. It worked for me. Alternatively, people have been having success with changing the location of the airport.
Good Luck.

MacBook Pro Airport Card disabled

Hello to everyone,
After the reboot following the last early june updates (10.5.7, Airport Client Update 2009-001 and iLife 09) I have a problem with my macbook pro 17' late 2008 (alu) Airport card : it is disabled and can't be enabled !
The airport internal card is BCM43xx.
To solve this after a few readings (I seem not to be the only one concerned with this problem) I tryed to :
o Make again a combo 10.5.7 update
o Re-install Airport Client update 2009-001
o Create another user on the computer -> not user related
o Delete the /Library/Preferences/SystemConfiguration directory, followed with disk authorisations repairing and a reset with PRAM erase -> The Airport started, but turned disabled again after a few seconds ....
I add the wifi network is made with an Airport Extreme, nothing was changed on this side and my other MacBook Pro airport is running fine (same updates, just an older MBP).
I also tryed to have a look at the console but found no errors, I have a frequent message : +(com.apple.AirPortBaseStationAgent) Unknown key for boolean: EnableTransactions+ but that's all ...
If someone has a few more ideas please help ...
Thanks a lot
Regards.

If this can help, I solved my airport problem by doing a SMC reset of my MBP. The airport card is now detected, with the latest updates.

Macbook Pro Airport Won't Connect When Macbook Pro Bootcamp Will

I have a Macbook Pro 2.16GHz Core Duo that has had problems with Airport connectivity since I got it. I can never get anyone to help me with it because it will never show the problem at the Apple Store.
One place that I have to work at has been very, very frustrating.
They have a number of access points called Wireless #1, Wireless #2, and so on. Every access point is a Linksys-Cisco WAP54GP. All of them are on channel 6. They are using a WEP 40-bit hex key with the same key on every AP. They don't understand the obvious flaws in their system, they will not change it nor help me...at all, so there's no point in suggesting things along that route.
I know that their network and their key works, though, because if I reboot into Windows on the SAME machine it works fine and the connection is great. Mac OS, however, will not connect and will not tell me why. All it will say is "There was an error joining the network." I have read suggestions saying that you have to put a $ or "0x" in front of the key to signify that it is a hex key (which I don't have to use on other WEP hex key networks), but when I try to type that in, the password dialog will not allow the characters $ or "x" and it beeps at me.
Does anyone have any help for me?

It will connect to other networks with and without
WEP. It will connect to other networks that use
WPA.
There are many networks, though, that give me the
"There was an error joining the network.", and I
don't know why.
I cannot enter a $. As I stated previously, the Join
Network dialog will not allow me to enter that
character when it is set to WEP 40/128 bit hex.
Also, as I have already said, I cannot change the
network to WPA. I understand the benefits of WPA
over WEP, but I am not the network administrator.
They will NOT change their settings. I know the
network works with Windows on my computer. What is
it about Mac OS that is preventing this?
Prior to the last Security Update, I believe 2007-02, broke access to 2wire Routers. It was very frustrating to me as well. The fault or problem, I believe, may lie in a firmware update to these routers. I performed one for my 2wire router and I am now able to connect.
My theory...

MacBook Pro poor performance in relation to NVIDIA GeForce 9600M GT

Hi All who may be having similar issues.
I am now on my third replacement custom Macbook Pro 2.66GHz with 7200rpm hardrive and 4Gb of ram, and yes am so peeved that this has happened again. I am aware of the article in the 'Inquirer' about the 'bad bumps' of the NVIDIA GeForce 9600M GT in these machines and realise it is not all but from the various postings and refurbished MacBook Pro's... quite a volume!
First off i also own an older powerPC imac 1.8GHz 2GB Ram and at my work use a 3.0GHz Mac Pro with 6Gb of Ram and a 2008 imac intel 2.4GHz with 4Gb of Ram. I am fully competent and primarily use for photographic programs such as capture one, photoshop, lightroom, Aperture and these new MacBook Pro modes has failed me in so many ways
I have read many threads regarding the possible reasons for why these cards are failing or at fault, and am encountering an attitude from apple that sees this problem as unique to me. Obviously not as from when i google or go into the discussion rooms
the issue?
make sure you are on the higher performance graphics card.
simple test.. take a screen grab( of anything in safari or even of the desktop) and press fn+F11 or however you configure your keypad to go to the desktop. you may notice nothing happens.. try again.. wait. you will see a delay and the commands follow when the computer catches up.
if all my other computers i use can do the easiest of tasks why can't this? seems incredible to me!
also after installing any of the above mentioned software and beginning processing raw files(in all the programs to make sure there was no software issue) the computer becomes very hot.. i get beach balling and regular crashes.. also the fact that my computers at work seem to work amazingly well with the above software versions. To add note, all machines have up to date apple software.
In the first machine i had it got so bad the dock disappeared and spaces crashed..the track pad froze and that was it. it took forever to start up and shut down.. it appeared to work on the lower performance setting intially but over time became buggy and crashed on that side too!
these last 2 models have behaved exactly the same... all the same custom configurations i have mentioned above.But i have recognised the problem straight off and asked apple for replacements.. i am now on the third and will call them tomorrow with the same issue. I just want a machine that works smoothly and reflects the price i have paid for it.
Has anyone else experiences this? any support or advice would be deeply appreciated.. i can't keep getting dodgy Shanghi custom models!!

I read your thread Nee Kun.. and thanks, yes that is the basics of my problem, but that is just a major signal that something is seriously wrong. The screen grab is the first test to see if a new MacBook Pro computer may have this underlying issue. what i found with my first 2 models was, this issue then developed into all the other issues i have described in my original post, so its not really the screen grab i am bothered about... however annoying it is.. but the fact that these machines over time on the higher performance graphics card become disfunctional and crash periodically say every 20 min of light photography retouching and processing then there is something that is fundamentally flawed in these over priced and under tested machines. i'm not a happy bunny.
However, I have been in discussions with apple and they are listening to my issue and we are trying to resolved it, but if not... it will have to be some form of compensation as i simply cannot do any high end work on these machines that a 3yr old powerbook, 5 yr power PC imac and all all the new range of imacs and mac pro's i have access to can! it is utterly bewildering!
hmmmm... will post an update as and when.

Macbook Pro - horrible performance - what can I do???

Macbook Pro 15"
Late model 2010 (December)
2.66 GHz Intel Core i7
8GB 1067 MHz DDR3 RAM
500GB HDD (437GB/37GB Mac HDD/Bootcamp)
Hi,
When I got my MBP in Dec 2010, it was very snappy running Snow Leopard.
My initial upgrade to Lion (Apple's version of MS Vista? LOL) had issues, I restored from Time Machine, but eventually got it installed. Almost immediately, the performance drastically reduced.
Eventually, I took it into Apple, they re-installed Lion from scratch (wiped the hard disk), and I did a partial restore from Time Machine. There's no guarantee I didn't regress some system files from my Time Machine backup.
The install of Mountain Lion was uneventful - the app store upgrade ran fine.
I was also getting a number of kernel panics, which were eventually isolated to (I think?) the GPU. Apple replaced the GPU under the Apple Care warrantee.
So, ever since moving off the original operating system, my MBP has had horrid performance. Some days worse than others, but lately very bad.
However, the timing could be a coincidence - I have also installed a number of third party tools (as we all do), and my HDD has 12GB out of 437GB left. At times it has had < 1GB before I copied files to an external USB drive. I don't deny my MBP could be bloated.
Sometimes when I close the laptop lid, then reopen it, the screen never recovers. 5 mins later the display is still black, and I have to cycle power. Sometimes just tabbing to a new text input field within Safari can take 30 seconds to move to the next field. Numerous other performance problems, I'm so sick of the spinning beach ball.
So, with that as background, some questions:
1) Any general advice on addressing poor performance under OS X 10.8.2?
2) Are there any *good quality* tools I can use to fix poor performance? I installed Mackeeper 2012 for about 10 minutes, before further web research convinced me to uninstall immediately. But I do like the concept, if a reputable company puts out a similar product. What about Clean My Mac???
3) Are there any tools available to test my hardware? I know Apple have them - that's how they detected the bad GPU. I'd like to run a full diagnostic check of my hardware.
(However, I also booted into Boot Camp. Windows 7 was very snappy, with the same hardware available to OS X. I suspect my problem is software related. Performance of the Boot Camp images under Parallels 8 is abysmal. Yes, I know a VM adds overhead, but Windows used to be just fine under Parallels.)
4) Or should I just take it to the Genius Bar under my Apple Care coverage? I've got 10 months left on the 3 year warrantee.
Any other advice more than welcome. Right now, I'm close to just wiping the disk and installing Windows 7 ;-). At this point, it really is unworkable, the performance is that bad. I really *want* to like my Mac and OS X, but lately I think "It Just Works" is just a bunch of marketing hype ;-).
Thanks,
Scott

Thanks for the quick reply...
1) Can I reinstall Mountain Lion from the recovery partition? I know I could with Lion; I assume the app store upgrade to Mountain Lion updates the recovery partition?
2) How do I run a hardware diagnostics on my HDD? Is there a utility that comes with Mountain Lion, or do I need to go to Apple?
3) Are there known apps that cause problems? I totally agree with your advice above - I should have thought of it lol - but it will be a PITA to implement. I can post a list of my apps if that will help. Note that the poor performance occurs even when few apps are actually active, and happens shortly after a restart.
4) How do I know what a TRUSTED app is? For example, I've got Chrome, but I've heard it has ahem "issues" on the Mac. But I don't know if that's the *cause* of the poor performance.
(Oops...ignore question #2, I'll search for how to do this...)
In short, if there is a way to shortcut these diagnostics, that would help. But yeah, I can see that what you suggest will probably what I end up doing ;-/
Thanks again,
Scott

MacBook Pro airport doesn't choose 5 GHz network when waking from sleep

Hi,
I recently set up a Time Capsule [TC] 802.11n (4th Gen) as my airport base station catering for my MacBook Pro [MBP], iPad (1st Gen), iPod (3rd Gen) and BlackBerry 9900. I have it set up in dual-band mode (2.4/5 GHz) with the same SSID, mainly hoping to take advantage of the increased speed of the 5GHz band during Time Machine backups - I get a Transmit Rate of 300 Mbit/s when connected at 5 GHz and 145 MBit/s at 2.4 GHz. Aside from that I don't really care which it chooses to be honest - my internet connection is only 12 Mbit/s. When I start up my MBP from a full shut down within an 'appropriate' distance from the TC, AirPort automatically selects the 5 GHz band and falls back to 2.4 GHz if I stray too far.
The problem arises when I wake my MBP from a sleep (which is pretty much always having closed the lid each time I'm done using it) and AirPort ALWAYS selects the 2.4 GHz band and will never change to the 5 GHz band unless I fully disconnect from the network and then reconnect.
The iPad and BlackBerry both switch happily between the two bands as I move around the house, opting for the 5 GHz when possible and always without intervention so the set-up obviously works.
I think it's a problem in Snow Leopard having read problems around the internet from users who have upgraded from Leopard to SL, most of whom seem to do what I'm thinking, i.e. setting up a different name for the 5 GHz network and putting it higher in the priority list that the 2.4 GHz one, however the solution isn't ideal/elegant and certainly not how it's supposed to work, but I've yet to find a definitive solution from Apple anywhere.
Anyone else having this problem? Anyone found a solution? Anyone heard anything from Apple?
Thanks!

Yes. I'm having a very similar problem. I don't have TC, but I have a netgear wndr4000. I'm always bring my MBP out of sleep and having to manually select the 5GHz band. Even when I know it should. I have different SSID's on each band, and I have tried setting the priority order, but that has another set of problems. When I get a little farther away, it will hook to the 5GHz band at 54Mb, but the 2.4GHz will be at 130Mb at the same distance. I thought it would make some type of smart choice about it.
I had been thinking about moving to a Airport Extreme because I've been told by others that their machines make the correct choice with the SSIDs set the same.
I too am on Snow Leopard, but I'll be upgrading soon.

TS3611 Macbook pro airport exclamation mark

Hi, I have a macbook pro and suddenly and completely out of the blue I now have this exclamation mark on my airport.
Internet was working just fine 15 mins ago and I have changed nothing. I have rebooted the router and my computer to no avail.
Is there anything I have overlooked?
Thanks in advance

Help!!! Macbook Pro airport wireless.

I purchased my Macbook Pro two weeks ago, May 27th, 2007. At the same time I purchased a macbook for my wife. My problem, my wifes macbook picks up five wireless networks to my one. Her macbook will connect to wireless networks and have a strong three bars, while my macbook pro either can't find the network, or can find it for all of 30seconds with one bar, and not even connect to the internet. While at my brothers home her macbook will have solid airport signal, and my macbook pro at the same time and place will have three maybe four bars. What's the deal?
Mac Book Pro 2.33 Mac OS X (10.4.9)

I can pickup a signal at Coffey shops, but not a signal at home. I have a 2wire wirless modem/router. My windows laptop will connect to it but my new macbook pro will not even detect the network. tech support didnt know what else to do after all the troubleshooting.

Macbook Pro Airport has no IP Address?

I was working on my MacBook Pro this morning and a few hours later I could not access the internet. I checked my network connections and I received an error saying "Airport does not have an IP address and cannot connest to the internet." I have no idea what could have caused this becuase I have not tampered with either the settings or the wireless router (which is a Linksys WRK54G). Any thoughts??
On a side note, I also went into the network settings to look at the TCP/IP tab since that what some people suggested and there is no IP address anywhere.
Message was edited by: Vinnie Parlatore

Welcome to the Discussions!
Cycle the power on the router; if that doesn't restore the IP address, then look at the settings within the router. Also, make sure that Airport is connecting to your router and not some other wireless network.

MacBook Pro AirPort issue

Hi,
I have the MacBook Pro model just before the unibody model. I'm having a little problem with my AirPort. Restarting hasn't worked. I can connect to a network successfully, but half the time I won't be able to use the internet. Sometimes it will work, but a lot of the time it won't. This happens for different networks, no particular one. What could be the issue and how do I get it work properly?? Thanks.

I don't that matters, it happens to any modem/router. Even the university ones. Really annoying not to be able to connect easily on campus. But this one here, is a "2WIRE" Bell modem. Don't know which ones the university uses.

MacBook Pro 15", performance, Aperture 1.1.x vs 1.5

Hello all,
thought I'd post some info about Aperture 1.5 on a MBP 15". I have seen many posts and ramblings about how the MBP 15" is somehow slow when using Aperture, especially compared to the 17" or other Intel machines.
My biggest gripes with Aperture 1.1.x have been, in order:
- It very quickly seems to force every other running application (and parts of the OS) to be paged out on disk, causing the system to be very, very slow even after quitting Aperture. Aperture itself also tended to get slower and slower the longer I used it, especially when using the fullscreen mode. Within 20 minutes of working with it it'd have slowed down to a crawl. And after quitting aperture, switching to - say - Safari would take upwards of half a minute, because things would have to be paged back into memory.
This is no longer a problem with 1.5. It's faster in general, and it STAYS THAT WAY! Yay!
- Rotating images, even ever so slightly, is very much slower than in iPhoto. No matter if I rotate a RAW or a JPG, no matter the size (within limits), and no matter if I rotate 5 degrees or 180 - iPhoto has always been a prime example of smoothness, even on old G3 and G4 computers (yes, I've made iPhoto 6 run on a G3, it's absolutely painless)!
This is still a problem, though it's become a lot better. What I cannot understand is why it should be that way -- why does it need to operate on the original file (I can't see any other explanation why it should be slower with RAW or large files) when rotating - before I've even released the mouse button?
Oh and another thing. It's useable on a MacBook now. Very much so. Thanks, Apple!

MacBook Pro 15", 2.0GHz, 100GB 7k2 RPM

I have the same setup as you, with mainly 9 and 16MB
Nikon D2H and D200 RAW files, and would agree that
there is a marked improvement. Although, being
cautious I am only testing on a small 'copy' library
with 5000 images, before going full time 1.5.
I've got about ~30.000 images in my library. Took about 40 minutes to convert on the MacBook (not Pro), where the library resides on an external FW drive. Picture browsing etc. is markedly faster than before.
I allowed the preview generating process to run overnight. It's done now.
I am not looking forward to creating previews
for 300GB libraries, but should mean that I can stop
using Portfolio.
Enjoy. But it's not as hard as it sounds. And you can keep working while it generates previews (in the background).
PS: My performance "feeling" is from before previews were generated. Might get even better

Did you MacBook Pro Retina performance improve significantly with Mavericks 10.9.5?

My MacBook Pro Retina (Early 2013) is one of the unfortunate ones that suffered from extreme scroll lag and performance slowdowns.
Beginning day one, I've had to employ workarounds such as using gfxCardStatus to force Discrete mode or to use a non-HiDPI resolution to reduce the symptoms.
To my surprise, when I upgraded to Mavericks 10.9.5, nearly all my issues have been resolved. I'm back using high resolution modes without a single bit of slowdown. Scroll lag is also minimal or entirely gone. The last issue I have is with the Applications dock folder and the 'folder' viewing mode still producing severe lag, but I can live with that as I use Alfred to launch my applications anyway.
Has anybody seen noticeable improvements like me? I queried others on MacRumors, but didn't get much feedback.

Adobe Application Manager was the culprit. For some reason with the XI install, Adobe Application Manager would not launch. I was able to resolve by deleting all
~/Library/Preferences/ associated with older versions of Adobe and by cleaning out ~/Library/Application Support/Adobe/Acrobat

Macbook Pro/Airport/Leopard drops Net connection after shutdown or sleep

I see all kinds of postings about problems with Airport and Leopard. I am pretty sure that the connectivity problem in my case stems from Leopard alone. I just bought a new Macbook Pro with Leopard installed. I have been using MacBooks running 10.4.x with Airport Extreme for several years with no problems. I still have no connectivity problems with 10.4, which is being used right now on the same Airport network. But, every time I shut down the Mac Pro or put it to sleep, it drops the connection. Here is a very weird thing: If I use network diagnostics, I can get back online right away after I put in my password (which is never saved). If I go through system preferences, it does not recognize my password at all (which is saved). I get this message: incompatible security. What does that mean?? There is something screwy in the Leopard software regarding security and passwords. Does anyone out there have a clue what is going on? I am not a computer expert and have no idea how to change security settings. I'm not even sure what they are. I do not want to do anything that will screw up the connectivity with the Macbooks running 10.4.11.

I had the same problem on my MacBook Pro for the last month or so after "updating" to 10.4.10. Yesterday I tried Loki's fix but couldn't connect at all after that. So I did an archive/install of 10.4.9 and it works better than ever before. I get full signal and it is a lot snappier and faster. The problem is likely in the 10.4.10 update, hopefully Apple will get that fixed in 10.4.11
