Solution may be found if you search in the "More Like This" section over in the right column.
First contact your ISP. You need to confirm that the issue is not on their end.
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.

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.

If using one of Apple's Airport routers, read its user manual or post in its forum area. If using a 3rd party router, read its user manual, contact their tech support department/website or post in its forum area.

I have OS 10.8.2 and use wireless at home just fine.
When I visit a friend with only a cable modem internet my Mac Book Pro will not connect.
I see that the Mac Book Pro is picking up the internet when I check the internet preference section but it will not open Safari.
What do I need to do connect via a cable modem?You need to power off the modem for 15-30 seconds, then power back up and then connect. The modem is remembering the last connection (your friend).

My Mac Book Pro will not power on
My Mac Book Pro will not (boot-up) power on.
What should I do?Do you have the power adapter connected? Does it display a light, amber or green?
Have you checked the battery charge level by pressing the exterior battery level button?
Try a SMC reset:

My mac book pro will not fully boot up. I have the grey background with the apple sign and the timer going round...but 20 minutes later still no desktop
You could try doing a hard shut down (holding the power button or yanking the battery) and then doing a safe boot by holding the shift key at startup:
http://support.apple.com/kb/HT1455
Also, not sure if this applies in your case, but I've had that happen when there's a USB drive inserted either in the computer or a connected external keyboard. I did a hard shut down, removed the drive and it went through a normal start up. -
Mac Book Pro will not start on Battery Power
Mac Book Pro will not start on Battery Power although battery at 98% need to connect charger. When started date and time incorrect, comes up as 1st Jan 2012.
What is the exact model of your MBP? The date change often is an indication of power loss to the MBP, such as disconnecting the battery.
If the SMC reset does not solve the situation, post this from your MBP:
Make certain that the power adapter is connected.

Mac OS X will not connect to wifi, airport is broken, will connect to internet with ethernet cord. Is there an accessory I can buy to replace airport so I don't have to use ethernet cord? Please help!!
Since the MacBook Pro currently works, you should put it next to the iMac and compare the network settings for AirPort in System Preferences Network pane Advanced. Also, if you want to start off with the default network settings, you can use Location drop down menu and select +Edit Locations+. Then click the plus sign to create a new location. Set up that new location.
On System Preferences Network pane, AirPort should appear at the top of the list (in the sidebar). To change the service order, click on the gear icon and select +Set Service Order+.
Some additional tests you can try, on top of seeing if it works with (1) WEP security disabled and (2) a direct wired connection to the router.
If you get it to work with either (1) or (2), be sure to run Software Update at least two times to apply any recent updates from Apple. See if that makes any difference to using AirPort with WEP back on.
(3) Start up in Safe Mode
http://support.apple.com/kb/HT1455
I don't know if any third-party software has been installed on the iMac at this point, but Safe Mode will start up with only the essential Apple extensions and processes running. See if it works any better in Safe Mode.
(4) Create a new admin user account in System Preferences Accounts pane
http://docs.info.apple.com/article.html?path=Mac/10.6/en/8235.html
Log out and log in to the new account. Try connecting with AirPort in the new account.
(5) Connect the MacBook Pro to the router with a wired Ethernet connection. Make sure its Internet access works. On System Preferences Sharing pane, set it up for +Internet Sharing+ so that it is set to +Share your connection from Ethernet - To computers using AirPort+. On the iMac, try to connect to that wireless network and access the Internet.
That last one (5) may be a good one to try first. It would at least show that the iMac's AirPort is working - you can even set it up to use WEP. If you have any questions about using the +Internal Sharing+ feature, please ask. -
My mac book pro will not recognize
My mac book pro will not recognize my hp printer after years of knowing it's connected. USB port works fine with other connections. I have reinstaled it. What do I do?
Hi ...
Go to the HP site and download the drivers (software) that is specific to your HP printer model > http://www8.hp.com/us/en/support-drivers.html
That way you will have the latest software available for your printer.
Then open System Preferences > Print & Scan - Print.
Select the printer on the left then click - (minus)
Now click + and follow the instructions. You may need to turn the printer off then back on before your Mac recogizes the new drivers.
You may also need to click the lock icon in the Print window in order to make changes. You may be prompted for your admin password.

17 inch MAC book pro will not boot up
My 17 inch MAC Book Pro will not power/boot up. The battery is charged and it displays a green light on the power adapter. However, it will not boot up.
Reset the SMC > http://support.apple.com/kb/HT3964
If it doesn't work, probably there's a logic board problem, so it's possible that you need a new logic board. Take your computer to an Apple Store or reseller -

MAc book pro. I have downloaded and installed os x yosemite now mac book pro will not start? How long should it take? Is there something wrong?
The 2 computers here took about 45 minutes to an hour each.
The best thing to do is give it more time. If it gets too ridiculous, shutdown using the power button and then restart. Check menu/About This Mac to see if it is installed. -

My Mac Book Pro will not start up. I ran the AHT and received the following error: 4SNS/1/40000000:Th0H-90.750. Anyone know what this means?
I have no idea how much it will cost to repair. I don't even know what the exact problem will prove to be. It may be quick if it isn't a motherboard problem. I just don't know. Take it in for a service diagnostic, then they can tell you what is involved.

My mac book pro will not shot down or restart.
mac book pro 13 2011 dec. mac os x 10.7.4. my mac book pro will not shot down or restart, my mac is to slow to much loading. . when i open some apps loading when i will restart my mac book pro
loading. i can't restart the same problem when i wil shut down my mac. need helpMackeeper has been known to cause more problems than fix, all the posts here say don't use it and offer instuctions on how to remove it, which is not as easy as just dragging it to the trash.
I am willing to guess that some of the third party software could be the issue.
Try a safe boot:
http://support.apple.com/kb/HT1564
Starting up in “safe mode” may help you diagnose problems you’re having with your Mac.
Note: To print these instructions, open the Help Viewer’s Action pop-up menu (looks like a gear) and choose Print.
Shut down your Mac and wait 10 seconds.
Press the power button.
Immediately after you hear the startup tone, hold down the Shift key.You should press the Shift key as soon as possible after you hear the startup tone, but not before.
Release the Shift key when you see the gray Apple logo and progress indicator (spinning gear).
To leave safe mode, restart the computer normally without holding down any keys during startup.
If you still have problems I would take it to Apple, there seems to be something strange going on here.
You search remove mackeeper on this forum, and get rid of it.
