2 1/2 yr old macbook suddenly will not make wireless connection

macbook, two and a half yrs old suddenly will not make wireless connection unless I am sitting directly in front of router. Any ideas?

Hi bluefatdogs2, and a warm welcome to the forums!
Probably a loose antenna cable, or the Airport card is dying. but I'd check the first, up under the Battery I think.

My Macbook Air will not print wirelessly!

My Macbook Air will not print wirelessly using the connection between it and my iMac which is connected via USB to my Canon Printer. The iMac and the Air are both using the same network and the printer is found on the Air... it sits at idle, but when I press "Print" on my Air it never actually prints. There is just a flash of the print icon on the Dock and then it is gone... I am left with no reason or error message. My colleagues are able to print wirelessly with no issue using their Macbook Pro and the same connected iMac. Can anyone help with this?
Macbook Air: OS X 10.8.3
iMac: OS X 10.7.5
Canon Printer: ImageClass MF4370dn

Hi JDP86,
Thanks for using Apple Support Communities.
If your printer is wireless-capable, you should first add the printer to your network. Use the printer's control panel, or temporarily connect the printer to your Mac via USB.

Macbook Pro will not remember wireless network

We have two Macbook Pros and are having issues with one of them not finding and then not remembering a particular wireless network. The other one works normally on this network, as do our iPad and iPhones.
The problem Macbook Pro will find a number of other wireless networks in the vicinity, but not the one we wish to connect with. However, when the required information about the network is entered into the Network Preferences, it does see the network and will connect with it, until the computer is shut down. When it is powered-up again, the Macbook will not find it, even though, in theory, it had been told to remember it and that network had been moved up to #1 in the order of priority.
The settings on both Macbooks are the same, so why can one find and remember the network and the other not? What can I do about the problem?
Help please!

Settings for wireless network connections are actually stored in two separate places on your Mac, so in addition to the correct advice offered by Jolly Giant, you will also need to delete old network listings in KeyChain Access.
Macintosh HD > Applications > Utilities > KeyChain Access
Locate the name of the wireless network that you want to delete and click it to highlight it
Click Delete on your keyboard
It would be a good idea to go ahead and also delete the current connection as well in case it has become corrupted. This will clear out the old settings and when you next connect to the network and enter the password, the new settings will be preserved.

HP Officejet 6500A Plus will not maintain wireless connection reliably

For the HP EXPERTS on Expert Day, April 18, 2012:
B.L.A.T. (Bottom Line At Top): We have an HP Officejet 6500A Plus purchased about 5 months ago. We wanted to use it as a wireless-connected printer in another room besides our home office. It is useless to us because it will not maintain its wireless connection, even sitting just a few feet from the router in the same room. Except for numerous hours of troubleshooting, we have left it sitting powered up, but unused and idle, for almost the entire 5 months in our home office. DURING ALL THAT IDLE TIME, IT HAS LOGGED OVER 3,200 DISCONNECTS, at a consistent rate of 24 disconnects every 24 hours, even though it ALWAYS reports that the wireless signal quality is “EXCELLENT” (all this is according to the Wireless Network Test Reports we’ve printed throughout the last 5 months). So our question is, what is it that this printer is trying to do once an hour over a wireless connection that is causing these thousands of disconnects? And how can we stop it?
NOTE! Before you round up the usual suspects (namely our router and our PC firewalls) please note that we also bought an HP Officejet Pro 8600 Plus ON THE SAME DAY as the Officejet 6500A Plus. The 8600 was also installed with a wireless connection, and has worked without a single network issue for the entire 5 months.
NOW, FOR THE REST OF THE STORY…
WHO WE ARE: My wife and I have worked on HP equipment for 33 years, starting in 1979 as corporate customers of HP when we worked for Exxon; then we both worked for HP directly for 17 years; and we’ve now used dozens of pieces of HP equipment in our home during the last 12 years in retirement. We’re primarily software folks, so we’re not exactly experts in hardware and networking, but on the other hand, this ain’t our first rodeo either.
OUR CONFIGURATION:
PC’s – All running Windows 7 x64 with all important patches applied and Norton Internet Security 2012: HPE-270f and HP AIO 200-Quad, each with full 6500A and 8600A drivers installed on wireless connection. These 2 PC’s themselves can connect either wirelessly or via Ethernet to our home network. The 270f has a dual-band wireless board. Both bands work. We also have a new dv7t laptop with only the full 6500A driver installed via wireless connection. The laptop is now upstairs and it’s connected to our home network wirelessly without any issues. (This is where we had hoped to also put the 6500A, but it needs to work reliably via wireless connection.)
ROUTER: Netgear N600 WNDR3700 providing Ethernet and wireless networking. Router provides a very strong wireless signal throughout the house. No wireless problems with any other equipment including an iPod, two Kindle Fires besides all the HP equipment.
PRINTERS: Besides the two HP printers, the HPE-270f PC has a Canon MP960 installed on it. And if we can’t get the 6500A working right or replaced with something that does work right, we may be buying our second Canon printer. By the way, on the 6500A, ePrint and App’s are set to ON, but of course they’re not being used, just like everything else on this AIO.
OTHER: We also have a Sonos music system that connects to our network via Ethernet and has its own proprietary mesh network (on another frequency) for transmitting ripped music wirelessly to speaker units throughout our house. (If you aren’t familiar with this totally cool system, check out sonos.com). We’ve never seen any evidence of interference between these two wireless networks, or our wireless phone sets either.
HP TOOLS AVAILABLE ON ALL 3 PC’s: HPU
UPDATE 5.003.001.001 (reporting everything up-to-date); HPHDU 3.1.0.17; HPPDU 5.0.0.015 and HPNDU 4.3.0.002.
SYMPTOMS: The 6500A Plus installs quickly and easliy, and connects wirelessly just fine during installation. But sometime over the next hour (usually less), it disconnects and won’t print from PC applications. Sometimes the application puts up an “Unable to communicate with printer” screen, even though the PC usually thinks the printer is “ready”. Other times, the PC thinks the printer is offline (but printers don’t have “offline” buttons anymore!). Often, if you just leave everything alone, the 6500A will somehow reconnect and print out the spooled file 5-30 MINUTES later. So it does usually seem to be able to recover given some time, but that doesn’t always fit our schedule! Occasionally, turning the wireless radio on the printer off and back on will fix it right away. But usually, you have to power the printer completely off, and then back on. As far as we know, that always fixes it…..until the next disconnect a few minutes later!
PREVIOUSLY TRIED: After reading some of HP’s wireless network support websites, I manually assigned a fixed IP address to this printer. It didn’t seem to matter; according to the wireless network test report, it still logs disconnects at the rate of one per hour, and all the failure symptoms were the same.
We also dabbled a bit with setting this printer as “trusted” to the Firewall, but that didn’t seem to matter either.
Next, we connected the printer via Ethernet. The printer immediately started to work, even though it had just been in its “failed” state over the wireless connection. As far as we know, it never failed while connected via Ethernet. This seems to point to a purely wireless hardware/firmware problem on the printer itself.
Late last year, I tried two different chat sessions about this with the inter-continental AIO support teams, each one lasting several hours. Unfortunately, none of their optimistic solution scripts seemed to fit our problem. They both seemed determined to reconfigure the 6500A as a TCP/IP printer, which of course worked fine initially, just like everything else. At this point, they would understandably want to close the chat. But 20-30 minutes later, we could no longer print to it. During the second chat, they got into one of our PC’s remotely and effectively turned off the spooler (by selecting “Print Directly” or something like that). After that, all was well again (as usual) UNTIL the printer disconnected, at which time attempting to print from that PC would HANG the application (since the spooler was no longer buffering) and eventually hang the whole PC. One giant leap backwards. That’s when I gave up on the multi-hour chat sessions.
The three diagnostic utilities (HDU, PDU, NDU) have been tried over and over. When the printer is in its disconnected state, the DU’s usually don’t detect the 6500A at all, or if they do detect it, they are unable to fix anything. Frankly, it’s easier to just power the printer off (which takes about a minute) and power the printer back on (which takes more than a minute) and then wait for the spooler to kick in (usually about 30 seconds). BUT WE DON’T CONSIDER THAT A SOLUTION!!
B.L.A.B. (Bottom Line At Bottom): We have used up nearly the entire black ink cartridge and at least a ream of paper troubleshooting this brand new printer, to no avail. This printer is useless to us unless it can maintain a wireless connection reliably. Please help!
Thanks –
Bob and Jane

I bought the Officejet 6500A Plus about one month and have experienced the very same problem. I tried to remedy this problem following suggestions in a number of different posts (static IP, router, firewalls etc), all to no avail. Last week I called support. The support I received by the tech over several hours and different days for a week was very good. However none of his suggestions corrected the connection issue. After today's recommended fix failed, he advised HP is aware of this issue with the 6500 and other affected printers. He claimed HP was working on a firmware upgrade. He did not know when the update would be provided. The tech also claimed HP acknowledged this problem in a written announcement. He agreed to email the announcement to me. I haven't received it. This has been the only problem I've had with the 6500

Week old macbook (white) will not read discs and ejects after a few seconds

Hello, my mother got her macbook a week ago, and while I was at school this week she hardly used it. I've come home today with my office mac 2008 disc and while trying to install I learned her macbook would rather spit the disc out than read it (does not even show up on the desktop). I know for a fact that the disc is not the problem, seeing as I just loaded it on my macbook earlier this week. I'm about an hour and a half away from an apple store so visiting is sort of an inconvenience. However Best Buy is about 10 minutes away, but I'm not sure if my apple care insurance will work there. Any ideas on how to fix it? Thanks in advance guys.

Apple has a 14-day return policy, so if the MacBook is only one week old I think it would be worthwhile to make the hour and a half journey to get a replacement, if necessary. For me, that would be better than taking it in for repair. Of course, while you're at the Apple Store they will take a look at it and perhaps they can quickly correct the problem rather than replace the MacBook.

My 4 year old macbook pro will not boot up. Help!

My 4 year old mac book pro has recently had a few episodes where it freezes up during operation, and then when I force shut down, I cannot boot up. When I try to reboot, I get a beep and the little circle spins for a while, then the screen turns a darker grey and I get a message to hold the power button for a few seconds to reboot, but this last time, it didn't reboot. It just does the same thing again and again. Does anyone have any idea what might be wrong? Is this mac book salvagable or is it time to buy a new one???
Thanks!
Jackie

My MacBook Air will not print wirelessly to my Canon Pixma MX410

I recently got a MacBook Air computer from work. I have not been able to set up the wireless printing at home via my Canon Pixma MX410 printer. I can get it to print from my MacBook Air if i connect it via USB. and I can get the Canon to print wirelessly from my personal Dell Laptop.
No matter what I have tried: Downloading the Printer Driver MX410 Series 106702.pkg
and still i get the same error.
The Printer is not Connected. I don't understand how that is, when i can still print from my other computer. There is some setting that i do not have correct on the MacBook. What do i need to adjust? I can't seem to find where it might be in the System Preferences. When i look at Network It show's i'm connected to my home Wireless Network. but i still am unable to print.
Please help.
Thanks!

My macbook pro will not sleep while connected to a Thunderbolt Display.

I am getting frustated on this issue after receving little assistance from apple support. I can put the macbook pro to sleep and all indications are that is sleeping. It;s hard to tell with a macbookpro retina because they don;t have the pulsiong light to show when in sleep mode like the non-retina models. I can put the laptop in sleep mode and then return 8 hours later to find the laptop is warm to the touch and doesn't appera to have slept during this time. I can follow exactly the same steps when "not" connected to the thunderbolt display and the macbook pro is cool to the touch and appears to have slept nicely. what is going on here? I am using a bluetooth keyboard and trackpad and the issue is replicated when in clamshell mode and when the lid is open.

I'm seeing similar behavior when I disconnect my TBD. My Retina MBP doesn't go to sleep. I get to work an hour later and it is very hot to the touch.
I'm not seeing lots of people complaining, so I wonder if it's something weird I do. Do you have VMWare Fusion or XQuartz running when you try and sleep?

MacBook Pro will not boot up, stops at Apple logo

My daughter's 3 year old MacBook Pro will not boot up. The grey screen with Apple logo comes up and it looks and sounds like it is going to boot up but after 30 seconds it goes black and turns off. Any ideas or suggestions would be appreciated.

The internal HDD will have to be replaced. Since you cannot get the MBP to acces the internal HDD, you will have either use Target Disk Mode:
http://support.apple.com/kb/HT1661
Or take out the HDD and place it in an enclosure and then connect it to the MBP via USB. (After you have installed the new HDD and the OSX)
You may or may not be able to get information off of the HDD.
Ciao.

My MacBook Pro will not connect to my home wifi but will connect everywhere else. My other Apple devices (I-pad, I-touch, another MacBook Pro) connect to the router without problems. It was working fine but all of a sudden stopped working.Thanks!

try this.
get back into your router's settings and start deleting devices that are not connected to your router.
you can also delete the ones that are connected - they'll connect again.
on the DHCP side of it, increase the amount of users that can connect/log in to your router.
see if that sorts it out for you.
good luck.

My Macbook Pro suddenly will not charge. I tried using 2 different cables and it still will not charge. What should I do??

My Macbook pro OS 10.10.2 suddenly will not communicate with my Cannon MX890 printer. I reset all printers and now I cannot seem to add a printer by using the Add a printer function. Ideas?

My Macbook pro OS 10.10.2 suddenly will not communicate with my Cannon MX890 printer. I reset all printers and now I cannot seem to add a printer by using the Add a printer function. Ideas?

The appearance of the printer in the Default view of the Add printer window relies on a protocol called Bonjour. There have been quite a few users who upgraded to Yosemite only to find that their wifi printer is no longer visible. Until Apple resolves this issue you can add your printer using the LPD protocol. To do so you will need to determine the IP address being used by the MX890. This can be done via the touch panel under Device Settings > Network Settings.
Once you learn the IP address then on the Mac you can click to add the printer and select the IP icon. Here you can enter the IP address, set the Protocol to Line Printer Deamon and leave the Queue field blank. Then change the name to Canon MX890 and in the Use menu, browse for the Canon MX890 series driver. Then click Add to complete the printer creation.

iSight camera failure after OS X 10.9 Mavericks update

Macbook pro will not recognize startup password

my macbook pro ( one month old)is running the latest yosemite and suddenly will not recognise my startup password. after trying a few times it does not give me option to use my apple id to change the password. It just jitters and doesn't start up. How do I recover.

First, make sure caps lock is not on.
Another reason why the password might not be recognized is that the keyboard layout (input source) has been switched without your realizing it. At the login screen, you can select one of the available layouts by choosing from the flag menu in the upper right corner, if it's showing, or cycle through them by pressing the key combination command-space or command-option-space. See this support article.
If the user account is associated with an Apple ID, and you know the Apple ID password, then maybe the Apple ID can be used to reset your user account password. In OS X 10.10 and later, this option also works with FileVault, but only if you enabled it when you activated FileVault. It's not retroactive.
Otherwise*, start up in Recovery mode. When the OS X Utilities window appears, select
Utilities ▹ Terminal
from the menu bar at the top of the screen—not from any of the items in the OS X Utilities window.
In the window that opens, type this:
resetp
Press the tab key. The partial command you typed will automatically be completed to this:
resetpassword
Press return. A Reset Password window opens. Close the Terminal window to get it out of the way.
Select the startup volume ("Macintosh HD," unless you gave it a different name) if not already selected. You won't be able to do this if FileVault is active.
Select your username from the menu labeled Select the user account if not already selected.
Follow the prompts to reset the password. It's safest to choose a password that includes only the characters a-z, A-Z, and 0-9.
Select
 ▹ Restart
from the menu bar.
You should now be able to log in with the new password, but the Keychain will be reset (empty.) If you've forgotten the Keychain password (which is ordinarily the same as the login password), there's no way to recover it.
*Note: If you've activated FileVault, this procedure doesn't apply. Follow instead these instructions.

Officejet Pro 8600 - Macbook Pro and Macbook Air will not print

Products:
HP Officejet Pro 8600
Macbook Pro (Mac OS X, Version 10.7.5)
Macbook Air (OS X, Version 10.8.2)
Question:
Why did my Macs initially print fine, but now will not print at all?
Full Story:
I have a wireless network at my house that consisted of a 30mb cable internet, Netgear 900n, HP Officejet Pro 8600, 2 Dell Laptops with Windows 7, a Lenovo Laptop with Windows 7, and Dell Tower with Windows 7 - All printed just fine.
The HP Officejet 8600 was added to my network about 2 months ago.
I added a Macbook Pro and a Macbook Air about 3 weeks ago. Both Macs printed just fine for about a week. Then suddenly they stopped. I spent about 2 hours on the phone with HP Service, and they finally said it must be my router. So I called Netgear. Netgear was useless! They wanted me to agree to charges for services before they would even discuss the issue.
Due to information provided by HP's service support, and because Netgear will not support their product, I promptly purchased a new router - an Apple Airport Extreme.
The Macs recognize the printer, will print if hardwired via a USB cable, but will not print wirelessly to the Officejet Pro 8600. The PCs print fine.
The frustration that is being felt is compound by the fact that the Macs printed just fine with the Officejet Pro 8600 2 weeks ago, and now the printer just shows "idle"... even with a new router. (see image below)
Please help, I appreciate any support.
As a side note, the HP Service rep was very friendly, and definitely tried to support the HP Product, which is much more than I can say about Netgear.
Thank you,
This question was solved.

Hi,
More likely the issue related with Multicast, which Apple devices relies on to communicate with teh device through the network.
First try unplugging the router for 30 seconds.
Plug it back to the power and wait for 2-3 minutes.
Turn the HP printer Off and back On, then check for any difference.
If the same persists, try changing your router configuration as following
Note: the settings below are not related with the HP product, I provide you the steps as a best effor and those are only based on my own knowledge. you may try modifying the router settings at your own risk:
Open the router configuration page (can be found listed as the Default Gateway by clicking the Wireless icon on the printer, then print a network configuration report.
Click the Advanced tab.
Click the Setup option from the menu, then click on WAN Setup.
Make sure to uncheck the box next to Disable IGMP Proxying and Apply the changes.
Click the LAN Setup on the same Setup menu.
Set the RIP Version as RIP-2 and Apply the changes.
Reboot your router and then check for any change.
I hope you may find that information useful, you may also use the user guide below for further information:
