Macbook Pro will go from full wireless connection to none

It is not the regular problem of the airport connection dropping. I will go from 4 bars in the airport menu to none, within a couple steps away from my airport extreme n router. I dont understand why this is happening, I am only about 20 feet from the router, so range should not be the issue, there is also nothing else to interfere with the connection.

I have a client with the EXACT same issue. The machine will work fine and then for no reason the bars will drop to zero and it will take about a full minute to find any connection. This issue just randomly started at work and coffee shops but he says it works just fine at home. The work router is an Airport Express with the most up to date software and hasn't been touched for a good 4 months. I am on a MBP right now and have had no issues while his Core Duo has all kinds of issues.

My MacBook Pro will not powerup (even when connected to power supply).

My MacBook Pro will not powerup (even when connected to power supply). The caps lock key is the only light on.

Hi PatB11902,
Thank you for visiting Apple Support Communities.
If your MacBook Pro does not seem to power on, but the caps lock key will light up when you press the caps lock key, you are likely seeing a video issue.
There are several steps that can help troubleshoot this behavior, found at this link:
Apple computers: Troubleshooting issues with video on internal or external displays - Apple Support
Start with these steps:
Reset the system
You can reset the Mac's parameter RAM and SMC.
Start up in Safe Mode.
If your Mac does not start up normally after these steps, here are some additional tips that can help:
Troubleshooting: My computer won't turn on - Apple Support
Verify you have a good connection from your Mac to the wall outlet by confirming the power cord and adapter if present are securely connected and plugged in. To check if the wall outlet is working, plug in a lamp or other electrical device.
If the wall outlet is working and you continue to have no power try another power cord or adapter if available. If it works you may need a replacement cord or adapter.
Disconnect all accessories that are plugged in to the computer, such as a printer, hub, or other mobile device.
If your Mac supports user-installable memory, solid state drive, or hard drive, and you recently installed any of these, make sure they are installed correctly and are compatible with your computer. If possible, reinstall the original memory or drive into the computer to find out if the behavior persists afterwards.
If you are still unable to start up your computer after trying each of these steps, visit an Apple Store or Apple Authorized Service Provider (AASP) for further diagnosis. If you plan to visit an Apple Retail Store, make a reservation at the Genius Bar using http://www.apple.com/retail/geniusbar/ (available in some countries only).
Note: Diagnostic fees may apply for issues not covered under warranty or the AppleCare Protection Plan (APP).

Macbook Pro 10.5.8 dropping wireless connection

Two days ago my late 2008 Macbook Pro started dropping it's wireless internet connection. AirPort, AirPort Settings, Network Settings, and ISP are all green lit, Internet and Server are Red. If I run diagnostics, I can get it to connect for about 30 seconds berfore it disconnects. Sometimes I can just turn off AirPort and then turn it back on and it will connect, but sometimes I have to set up a new location. The menu bar shows full signal the entire time. It works if I connect with an ethernet cable. No other device in the house (2 PCs, a 2 year old Macbook Pro, and several iPhones) is having this problem. Both the laptop and router (airport express that I've used for more than a year without a problem) software were up-to-date prior to this issue. I'm not that computer savvy when it comes to things of this nature. I have no idea what's causing this problem, but it's driving me insane.

Yes it does for a while though at a low level then it shows the ! no connection. It restores to normal after a while and works normally for a varying length of time.

HT1349 My macbook pro will not print to wireless printer-it just printed fine the other day. Even reloaded the printer driver, etc, message is "there is a communication error" -in the printer queue it says it is printing then error message pops up

Macbook Pro unable to print to wireless printer-other PC prints fine and mac just printed a couple days ago just fine. Tried reboot of router-no change, tried reinstall printer driver, etc, no change. what do I do now?

As you can see here, that particular Canon printer is not supported by AirPrint:

New macbook pro 2011 weak and dropping wireless connection

Just looked throught this part of the forum and found out there are a lot of people out there which seem to have the same problem as me.
I purchased a new modell 2011 MBP on the very first day from our apple store.
At home, sitting directly beside the wireless router I didn´t noticed anything wrong.
I have got beside of the Mac OS a bootcamp Prt. with Windows 7 on it and everythign works fine so far.
Five days after purchased I started traveling on business and at present we are for some weeks in Melbourne. Were having a wireless connection in our appartement and here I have got massiv problems with my connection.
We are having altogether four windows mashines with us, my IPad, my Iphone, another HTC smartphone, and my new Macbook.
All the other devices connecting to our room wireless without problems. The net strengh is not fantastic but the other devices bringing it up to four bars on the windows wireless symbol in the task bar. None of the other computers where ever loosing the connection.
Only my macbook can not make it over three bars and its going on and off. Donwloads fail freuquently because the conection is interrupted more than one times..
In my opinion this problem is even worse on the Windows OS and a bit better but far away from beeing good and acpetable on the Mac Os.
I hope its only a driver issue and there is no hardware problem with the new mashine. Other than this I love the new notebook and I am very satisfied with its performance.

Hi,
I've noticed similar behavior - specifically with the new 2011 MacBook Pro 13 and 17" models (tested) on Cisco infrastructure - using a 1252 and 3500i/e series APs running in dual-band mode, with 5GHz preferred. I've seen the transfer rates when in close proximity to the AP move between 72mbit and 243 - occasionally 300. My 2010 system in the same position is a solid, dependable 300.
They did modify the wireless chipset in the new 2011 MacBook Pros to replace it with a true 3x3 802.11n device. Cisco have long praised the Broadcom chipsets so I will see if their wireless team can advise me on what this new gear is capable of.
I currently look after a very large deployment of wireless LAN equipment so my wireless performance is absolutely critical to my work - the 2010 system was a godsend and a testament to how wireless devices should be built. It looks to me like this could be a software issue so I only hope Apple resolves this ASAP. I'll hang on to my 2010 system for now...

My MacBook pro will not turn on after connecting to an external display

I connected my MacBook pro to a projector for a presentation using a VGA adapter. It worked for a couple of minutes, then my computer shut off and I can not turn it back on. It has never given any trouble before then. Now when I try to turn it on, the white led comes on briefly, then it makes a tone and nothing happens, the screen stays dark, any idea what is wrong????

Probably option, command, P, and R to reset the pram. Article at link.

My Macbook Pro will not start with battery connected.

I have a Macbook Pro which I purchased in 2011 and recently it would not start. I later disconnected the battery and plugged it in and it now works but only without the battery disconnected. When it would not work and the battery was connected, the battery lights indicated that it was fully charged. Any suggestions?

Was this a used MBP, the 2011 MBPs only have internal batteries. How did you disconnect the battery?
This behavior sounds like a failure or fault in the batttery circuit and the only way to diagnose that is by taking the MBP to an Apple store genius bar or Apple authorized service center to have the techs run their tests.

My macbook pro (lion 10.7.2) stopped connecting to wireless internet even though network indicates it is connected - full bars.

My macbook pro (10.7.2) just stopped connecting to the internet. 2 other macs in the house are working fine. All 3 are in the same room as the airport. The macbook network icon indicates it is connected with full bars. We have turned the computer off and on, but no effect. Any ideas?

Have you tried turning Airport off and then on again? My own q about this is somewhere in the answered q's--what worked was either the Airport on-off or something my phone company did while I was fiddling with Airport. Good luck!

Airport Extreme Connected to Internet but Macbook Pro will not

I'm living in an apartment and using an Airport Extreme to supply wireless connection. The internet is paid for by the apartment complex and I have no access to the modem. Up until yesterday the internet worked fine for all devices. I did several factory resets on the Airport Extreme and now have confirmed internet access with my PS3 and smartphone connected to the wireless network. However, my macbook pro will connect to the wireless network but will not go beyond that to the web. I have renewed DHCP leases, reset network configurations and deleted plists to refresh everything but it still does not work. I have noted that when connected to the network, I have an IP address that begins with 192.168.x.x and the macbook states the router address begins the same way. The Airport Extreme displays an IP address of 172.xxx.x.x
I can manually input the routers IP address into my laptops network configuration and create an IP similar and connect to the internet through the laptop but if I want to connect to other networks I have reset that information. It simply won't work automatically. The airport extreme is setup in bridge mode. That is the only setup which would offer stable networking without any dropping or the device disappearing from the airport utility.
I'm currently out of my apartment and will call my ISP later today, but this problem has affected my roommates macbook's as well. My last attempt to connect directly into the wall ethernet jack yielded the same results without any internet connection.

Try this:
Put the Airport Extreme in Bridge Mode and plug the apartment ethernet cable into a normal ethernet port on the back of the Airport Extreme instead of the normal "Internet" ethernet port.

My MacBook Pro will not open any application or program that requires internet, even though I am connected to the web.

My MacBook Pro will not open any app or program that requires Internet, even though I am connected to the web. I recently installed Norton AntiVirus and think it may have changed a setting that I couldn't find. I uninstalled Norton and it didn't help. Every time I open Safari, iTunes or any other program that tries to connect to the Internet, it crashes. Strangely enough, Skype still works, but nothing else.
I have OSx 10.6.8.
I have tried erasing plists, and all the standard troubleshooting, ie resetting modem, restarting computer, reloading Safari from disk.
Any help would be greatly appreciated. Thank you in advance.

Change your router channel. Sometimes this is all you will have to do.
Power cycling the router. Read the router's user manual or contact their tech support for instructions.
System Preferences/Internet & Network/Network
Unlock the padlock
Locations: Automatic
Highlight Airport
Click the Assist Me button
In the popup window click the Diagnostic button.
System Preferences/Network- Unlock padlock. Highlight Airport. Network Name-select your name. Click on the Advanced button. Airport/Preferred Networks-delete all that is not your network.
Place a check mark next to "Remember networks this computer has joined." Click the OK button and lock the padlock. Restart your computer.

I uninstalled Norton and it didn't help.
To properly uninstall Norton software follow these instructions - Locate Symantic Solutions folder inside the Applications folder at the root level of your HD, launch the Symantec Uninstaller application, select the Symantec AntiVirus Corporate, Norton AntiVirus & Norton AntiVirus Auto-Protect entries and click the Uninstall button.
Confirm your decision when prompted and then enter your administrator password in the space provided.
Retart your computer & Norton should be gone for good.
If the above does not work, download a copy of Symantec’s RemoveSymantecMacFiles removal utility. This utility will launch Terminal & remove the Norton components.

MacBook Pro will not connect to the internet

Both my iMac and macbook pro will not connect to a certain web site?

Both my macs (21" new iMac & a 2008 macbook pro) will not connect to foxcycling.co.uk. I know the site is live as I can access on my iphone and ipad.
From what I've read on the forums its a settings issue which probably migrated from the macbook to the iMac when I migrated the data.
Very frustrating ....
Any idea's and simple solutions?
Both systems up to date etc

OK, OS X does not include Adobe Flash. The website is probably Flash based. Chrome has Flash incorporated into it. If you want to download and install Flash visit Adobe's website and download Flash for your system.

Freeing Up Space on The Hard Drive
1. See Lion/Mountain Lion/Mavericks' Storage Display.
2. You can remove data from your Home folder except for the /Home/Library/ folder.
3. Visit The XLab FAQs and read the FAQ on freeing up space on your hard drive.
4. Also see Freeing space on your Mac OS X startup disk.
5. See Where did my Disk Space go?.
6. See The Storage Display.
You must Empty the Trash in order to recover the space they occupied on the hard drive.
You should consider replacing the drive with a larger one. Check out OWC for drives, tutorials, and toolkits.
Try using OmniDiskSweeper 1.8 or GrandPerspective to search your drive for large files and where they are located.
If you are no longer able to boot your computer, then the drive is too full and has become corrupted. You may be able to repair it using Disk Utility on your Installer DVD:
Repair the Hard Drive and Permissions
Boot from your Tiger Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
If this doesn't work, then you will have to erase the drive and install OS X from scratch. From the Tiger installer disc you will choose the Erase and Install install option.

I have a macbook pro 15 retina - when ever I connect to bluetooth speaker, I get this loud noise coming from the speaker - if I turn bluetooth off, the noise is now coming from the macbook speakers

I have a macbook pro 15 retina - when ever I connect to bluetooth speaker, I get this loud noise coming from the speaker - if I turn bluetooth off, the noise is now coming from the macbook speakers & stays until i restart.

Hi John. Thanks for that input. At Step 6, after clicking "Next" I get a window telling me my OS version is unsupported and the installation may not complete. I am prompted to go to Canon's web site to "Check Latest Info".
I've had this window on previous attempts and from Canon's web site I downloaded two drivers as follows
- ICA Driver V4.0.0
- Canon IJ Network Tool V4.5.0
I'm not sure if these are the correct / complete drivers I need for this install or not.
I continue to follow all the steps. At step 9 I click "Wireless Set Up using USB" amd get a License Agreement (a little different than instructions)
I click "Agree" and it goes to a Setup window with two progress bars showing the installation. I've not been prompted to connect the USB?
After the Setup window is done, I am then prompted to connect the printer via USB. I connect the printer and click on "Redetect". It is not detected.
I then try following the Canon on screen instructions for connecting to the wireless LAN amd enter the password. It searches and indicates "Connecting" on the window, but it never connects and the blue light just blinks
So, at this point I am stuck??
Thanks
Stephen
