Macbook Pro (Leopard v10.5.8) connectivity problems

Computer:
Unibody Macbook Pro 13" from August 2009 (running OS X 10.5.8)
Problem:
Randomly, my AirPort card will turn off and occasionally the computer will freeze up. This issue arose after Apple replaced the Logic Board for a faulty audio-out port. After trying various methods to reset the network, Apple replaced the AirPort card. I am still experiencing the issues.
+I have recently noticed that the issues have only ever occurred when the computer is running on battery power. The computer is able to be problem-free for days (until unplugged).+
_*What I've tried to do already (if you're having similar connectivity problems, these may solve your issues):*_
1) I have cleared out all networks saved onto my computer under "Advanced" settings in the "Network" section of "System Preferences".
2) I have reinstalled all current updates for my version of OS X Leopard
3) I have attempted to reset the PRAM (turn on the computer by holding "command" + "option" + "p" +"r" and the power button). Sometimes this will turn the network back on and sometimes it won't. However, even if it works, the connectivity issues still come back.
4) When the computer has frozen up, I have reset the SMC:
+For early '09 Macbook Pros and later:+
+Shut down the computer.+
+Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.+
+On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.+
+Release all the keys and the power button at the same time.+
+Press the power button to turn on the computer.+
+Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.+
Obviously, this also has not solved the problem.
5) I have gone into Macintosh HD -> Library -> Preferences -> SystemConfiguration and deleted the following Plists:
com.apple.airport.preferences.plist
com.apple.nat.plist
com.apple.network.identification.plist
com.apple.PowerManagement.plist
Networkinterfaces.plist
Then restarted the computer. Just like #3 and #4 this sometimes solves the issue, but only temporarily.
This problem has become very frustrating because every time I think I have it fixed the issue pops up again. If anyone has suggestions for something I haven't tried, I am more than happy to welcome your input.
Thanks,
Mark

Hi g,
Software Update will update, but will not upgrade the OS. To upgrade the OS to Snow Leopard 10.6.8 you need to purchase the disc for $29 and install it, then run Software Updates.
I have no idea if this will resolve your issues.
Do you have at least 15% free space on your HD?

I have a problem with using MacBook Pro as wifi router when connected to ethernet

I have a problem with using MacBook Pro as wifi router when connected to ethernet. The Airport icon changes to show a laptop inside, my iPad shows connected (I think) but Safari will not operate. I tried pinging my iPad, it seems to see the iPad, but no connection to Safari or to other apps such as Good on the iPad. I have read many posting and tried repeatedly via Sharing in Systems Preferences, but no luck. Suggestions to fix, or is this a Lion problem?

Usually this is a problem related to the domain name server address. If you open Network preferences, select your Ethernet port then click on the Advanced button then on the DNS tab. You will likely see an entry like 10.0.1.1 already listed. Click on the Add [-] button and enter 208.67.222.222 then click on the OK button and then on the Apply button. See if this helps.
if it does not help then repeat the above but with the Airport port.

I have a 16GB iPhone 3GS. Tried synching my phone through iTunes (11.0.1 I think... on a 2009 Macbook Pro). Now when I connect to iTunes, it says it does not recognise the content on my phone. Is this because my phone (and laptop) are too old?

Also, when I tried to Restore the settings, an Error Message pops up that says " The iPhone software update server could not be contacted. The requested resource was not found.
I'm trying to free up space on my phone by removing [literally] thousands of old photos which were originally synched to the phone, because I had forgotten to uncheck the photos button when I synched it ages ago.
I have also tried synching it on my 24" iMac (running OSX Snow Leopard). But again, when I try restoring the phone through itunes, it says the file is corrupted. It sggests unplugging the device, and then plugging it in again. I have done this numerous times with no success.
I'm guessing it must be because my phone (and versions of iTunes, and OSX) are all too old.
Please can anybody help.
Cheers,

There are multiple reasons that lead to issue. You should read the troubleshooting guide to get the right solution to solve the issue: iPhone, iPad, or iPod touch not recognized in iTunes for Windows - Apple Support

Restarting MacBook Pro, Apple TV and WiFi router could solve the problem.

MacBook Pro continually drops wi-fi connection

My MacBook Pro drops the wi-fi connection at intermittent times all day. Sometimes, only after it goes to sleep. Other times every few minutes. Had Cox check all cable connections. No problem. Geniuses at Apple Store said it's an Apple problem, needs an update. Online Apple support agreed. Incredibly annoying. Only problem I've had.

Since you've only had a week take it back and get a refund. Apple has a 14 day no questions asked return policy. Return it for a refund and buy another or something else that works correctly.

My MacBook Pro shuts down when i connect a USB cable.

My MacBook Pro shuts down when i connect a USB cable, only when its a 30 pin apple cable. Well one USB shuts it down and the other one doesn't work at all.
it only happens when i use an apple cable. It has no problem with my external drive nor with other things.
Ps. i did use different apple cables and they all shut it down.

What are you connecting? iPad, iPhone, what?
When you say a 30-pin Apple cable do you mean a Lightening to USB cable?
Little more info needed...

I can pair my iPhone 4 with my MacBook and my Macbook Pro but they will not connect. My iPhone keeps telling me it does not support this even with bluetooth turned on.The devices section keeps searching all the time

I can pair my iPhone 4 with my MacBook and my Macbook Pro but they will not connect. My iPhone keeps telling me it does not support this even with bluetooth turned on.The devices section keeps searching all the time. Is this an antenna problem? Or something else ?

Your iphone is right, it is not supported. The iphone's bluetooth protocols do not include file transfer, but are intendes only for headsets, stereo headphones, cars, and keyboards.

Download speed higher with MacBook (tiger) than with MacBook Pro (Leopard)

I am using a MacBook 2GHz intelcore Duo (with Tiger) and a MacBook Pro 2,16GHz (with Leopard), both with an Airport Extreme connected to an 20Mb/s internet. The Airport is placed in a room, the workplace in another room (distance 12m).
Close to the Airport, a speedtest gives for boths computers +/- 19Mb/s. On the workplace the speedtest gives 19Mb/s for the MacBook-Tiger and ...... 6Mb/s for the MacBook Pro-Leopard. On both the signal strengthmeter is on maximum. Still I can only conclude that there are 2 possible culprits: the antenna or the OS.
Does anyone have another explanation or, better, a solution to offer.?
Thanks

On my quad G5, on the space designer tests going from L7 to L8 on 10.4 lost about 25% of available plugins. Going to 10.5 on L8 (I haven't checked L7 on 10.5 yet) that drop went up to about 50%. On the sculpture test, it only lost one plugin each step of the way.
I'll post complete numbers when I'm done testing. I'm very curious how intel boxes compare (I'll probably test my intel mini over the weekend). I also wonder if it's a case of L8 doing poorly with songs created in L7, I may create the same songs from scratch in L8 and see if that improves anything.
While benchmarking apps are interesting, they don't necessarily reflect how real apps run. It looks like xbench isn't 64 bit or even multicore aware, making it of limited use. There's another benchmarking app called geekbench if you want to check out an alternative.

My iSight is not working on my Macbook Pro. What are the possible problems and solutions?

My iSight is not working on my Macbook Pro. What are the possible problems and solutions?

Hello Douglas,
Thank you for the details of the issue you are experiencing with the built-in iSight camera on your MacBook Pro. I recommend the following steps for this issue:
Important: Follow these instructions in order. Test the camera between steps to see if the issue is resolved.
Built-in iSight cameras
These steps are for iSight cameras that are built into a computer, such as the iMac G5 (iSight) or later, the MacBook, or MacBook Pro.
See if the issue is application-specific.
Try another application (iSight works with applications like iChat, PhotoBooth, and iMovie HD 6) to see if the iSight camera exhibits the same behavior in all applications. If it only happens in one application, try reinstalling that application.
See if the issue is user-specific.
Test your iSight camera in another user account. If the issue only occurs in one user, the issue would be isolated to user settings.
Find out if the computer recognizes the iSight
Check System Profiler (in the Utilities folder, inside the Applications folder). Under the USB header, check to see if the iSight camera is detected.
Reset SMC or PMU
Reset your computer's SMC or PMU, and then check System Profiler again. (SMC reset instructions for iMac G5 (iSight), Intel-based iMacs; PMU reset instructions for MacBook and MacBook Pro.)
If your built-in iSight camera is still not behaving correctly after trying all these steps, you may need to contact Apple or an Apple-Authorized Service Provider for service.

You will need to install an App like Print Central on the iPad to try to print to the printer. It will allow you to print to most printers. Check with their support folks if you need more info.

Macbook Pro 10.6+ will not connect to wifi network

Having a strange issue with one particular Macbook Pro not being able to connect to the internal wifi. There are 5 machines, mix of Windows and OS X, none have this issue. We have a wireless network coming from a SonicWall router with wireless capability. This particular Macbook will not connect to the wifi. Just an "!" symbol around the wifi. It has no issues connecting to any other wifi in the area, even to a second on within the same floor.
What are steps to troubleshoot? I am an advanced Windows user and would check ipconfigs, flushdns, among plethora of other things. I am not so sure about what to do in OS X (10.6 or 10.7, not sure).
Any guidance would be appreciated.

I can assure you it is not the router. I am pretty good with Windows and Networking, particularly these model routers. This is an issue on the laptop. I feel as if it keeps remembering old credentials to this wifi network (when user kept typing the wrong password). Once I changed the WiFi password, it no longer even asks me to update the WiFi password when attempting to connect. I have to manually try to connect to it by inputting SSID and password and still does not accept.

Trying to set up my brand new MacBook Pro and it does not connect with the wifi network I have selected for this purpose. Nothing wrong with the wifi as both my iPad and iPhone are happily connected. Suggestions for connecting to the wifi network accepted

Setting up my brand new MacBook Pro and it will not connect to the wifi network. Nothing wrong with the network which is happily working for my iPhone and iPad! Suggestions accepted for making this connection.

Fixing this is a two step process:
1) System preferences > WiFi/Airport ...
... check [√] Ask to join new networks
"Known networks will be joined automatically.
If no known networks are available, you will
be asked before joining a new network."
2) Remove unwanted networks from the list of "known" networks under
System preferences > WiFi/Airport > (Advanced) > | Airport/WiFi pane ...
Close the window and save changes. If no joy, do a restart to ensure you are playing under the new rules.

I have a 2011 macbook pro, buy yet when I connect my 16GB or 8GB Sandisk Extreme class 10 30mb card, it wont read it, however, it reads a 2GB class 2 card, is there anyway to fix this?

I have a 2011 macbook pro, buy yet when I connect my 16GB or 8GB Sandisk Extreme class 10 30mb card, it wont read it, however, it reads a 2GB class 2 card, is there anyway to fix this? and no, there is nothing wrong with the cards, they shoot fine, my dell inspiron 15 reads these cards fine, but yet my brand new macbook pro does not.

After many days of frustration, I try a stupid thing.... Put the SD card in the Lock Position and... Voilá!
The way I find to access the content is put the SD card in the Lock position..
