My macbook pro 13inch late 2011. The WiFi has stopped working.

It picks up the network but tells me I'm not connected to the internet?

I'm connected through a router.
I don't really know the details of it but I know that the router works because other computers in the house are able to connect one of which is exactly the same as mine.
Mine was working and then minutes later it just stopped connecting and hasn't connected in two days to any network, including ones that I have never had trouble with before.

I bought a MacBook Pro in September 2011 and it has never worked well.

I bought a MacBook Pro in September, 2011 and it has never worked well. Are there known issues with this machine? It just stops responding, usually for 3 minutes (especially when I'm working in iPhoto or Contacts). I regret buying this machine. I wish I could just go back to my previous MacBook Pro. Any chance Apple will just exchange this for me without it costing me my other arm & leg?

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of this exercise is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login. Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
Note: If FileVault is enabled under Mac OS X 10.7 or later, you can’t boot in safe mode.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem(s)?
After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

I have taken it back to the Apple store genius bar, but they say they don't see anything wrong. Well unless you use it all day and experience the problems when they happen, you wont see anything wrong. But there are lots wrong with it. But this would be the same store as I purchased the phone. And they backed up my old Iphone 4, but were not able to get anything to load back onto my new phone. So, I lost pretty much everything. But over time, some of my contacts have started showing up, although i am still missing over 800 of them.

Macbook Pro 15 "(late 2011) failure of the graph?

I have a Macbook Pro 15 "late 2011. Anyway, yesterday suddenly working with photoshop choppy with many stripes screen mode interference stayed. Thing goes off and no longer gray top with window apple and can distinguish some weird lines in the background.'ve noticed that much heated and the fans spinning at maximum causing a lot of noise, but very exaggerated even going to burn and thought it is the graphics card. Des then ever Very few, I get to open the OS but asking him to do something that required a bit of thinking and resources are left hanging and computer exorbitantly warm after a while of being on, with fans the most.
I report and I've seen these Google Apple Macbooks Pro have had problems with this model, which came with the faulty graphics card and there are many cases like mine the net.
I've led the service and have told me it's the graphics card and ask me € 650 to change the motherboard and the graphics card is integrated into it.
Because there are some times reaching to open the operating system and some not? If the graphics card failure should never be opened or seen anything on the screen ...
Because if the graphics card fails the computer so hot? Something does not look clear or logical in this ...
I was very happy with the laptop and Apple products even recommending their products worldwide.But now I feel ripped off by Apple, very unhappy and never'll buy an Apple product and will recommend to anyone else. I think if a laptop goes with any defective part must be arranged at no cost by the consumer no longer has warranty though. If your products are of such quality that do you find such a product to market and not requite the damage? I thought Apple products were of high quality and durability ...
The question is how Apple leaves the market one produxto flaws and is not responsible?
I would like a response from the company
Actually, I'm very disappointed.

noice T greetings: Your comment suggests that you have had less than satisfactory results in dealing with the staff at the Genius Bar. I am disappointed to hear that. I on the other hand have found them to be good to excellent for the most part (yes I do recall a less than satisfactory Genius). I think ffmcollins' problem is better addressed at an Apple Store than at Best Buy.
Ciao.

20" Apple Monitor - Thunderbolt - MacBook Pro 15" (late 2011)

I have an Apple 20” monitor with an HDMI cable. I had that monitor connected to my Macbook Pro 15" (late 2011) with an HDMI to Mini adapter, and it was working fine as a second monitor.
I purchased a Thunderbolt monitor to daisy-chain the Thunderbolt monitor to the Apple 20” monitor and end up with a 3 monitor system, but I cannot get it to work.
This is the way I have them hooked up:
20” Apple Monitor (HDMI Cable->Mini) -> Thunderbolt -> MacBook Pro 15” (late 2011)
The 20”Apple Monitor does not show any image even though it is on and working properly. The Thunderbolt and MacBook Pro displays show the images. How do I connect these?

You could use a USB to DVI converter
<http://eshop.macsales.com/item/NewerTech/VIDU2DVIA/>
but performance will be severly limited by USB and some functions won't work

What is the max memory allowed on a macbook pro 15" (late 2011), and what speed is the max speed allowed?

Hello,
I own a Macbook Pro 15" (late 2011) and I would like to upgrade the memory. I want to go with two 8gb sticks but if the motherboard only supports 8gb then I will have to stick with 8gb. Also, the ram that I have in currently, which is the 4gb that came with the mac, is 1333 Mz. Would I be able to upgrade to 1600 Mz on this laptop?

Max is 16 GBs. Do not attempt to use memory with specs that differ from those required by your hardware.
Maximum Memory
16 GB (Actual) 8 GB (Apple)
Memory Slots
2 - 204-pin PC-10600 (1333 MHz) DDR3 SO-DIMM

Hi, I have a late 2011 MacBook Pro but cant get the mirroring function to work with Apple TV. I've got the most recent Software 10.7.5 but cant see the mirroring icon or turn this on. I'm able to mirror from my Ipad but not my Mac, any thoughts?

Welcome to the Apple Support Communities
AirPlay Mirroring is supported on your Mac, but it needs OS X Mountain Lion (10.8). See > http://support.apple.com/kb/HT5404
You have two possibilities:
1. Make a backup, open App Store and purchase Mountain Lion to upgrade to this OS X. Then, you will find the AirPlay Mirroring icon at the top right of the display, on the menu bar, or on System Preferences > Displays.
2. Keep OS X Lion and use AirParrot > http://www.airparrot.com
Both options work properly, but I recommend AirPlay Mirroring as it doesn't need a third-party program

I have the new macbook pro from late 2011. when i try plugging my cannon gl2 into the mac via firewire 800 it does not show up in iMovie as an option to import from. i even have gone into my settings on the camera and changed it to vcr.

I have the new MacBook Pro from late 2011. "the one before the new ritina display" i have a cannon gl2 video camera which is mini dv. when i plug it into my mac via firwire 800 it does not show up in the iMovie. i have set the settings on the camera to vcr mode and changed it to av->dv out. when i click on the import from camera on imovie it doesnt even show my camera in it. it just gives me the option to import video from my facetime camera. the camera is turned on the wires are connected i know for fact that its a firewire and not a usb. i know what they each look like. i bought the firewire cable and it was marked down cause it was an opened and used item. would it be possible that it could be deffected and if that is not the reason what other options do i have?

I would say that odds are high that you have a bad cable. Maybe that is why they returned it.
I would suggest trying a different firewire cable.
You can find Firewire cables inexpensively at monoprice.com. You need a 4 pin to 9 pin firewire cable.
Here is a link.
http://www.monoprice.com/products/subdepartment.asp?c_id=102&cp_id=10301
Other things to check:
Is your camera plugged in to wall power (not to batteries only). Must be hooked to an AC power source to import.

I want to upgrade the ram on my macbook pro 13inch (early 2011). i found an 8Gb (4Gb x2) PNY "mac compatible" that is DDR3 PC3-10666 but my macbook is a PC3-10600. Do i need to use a ram with the exact specifications that my macbook lists?

Yes that is your best bet. Without looking at it too closely double check your options here:

I have a macbook pro 13' (late 2011) 2.8Ghz Intel i7 memory 4GB 1333 MHz DDR3 and have upgraded my OS X Lion to Mavericks. Everything has slowed down. How do I go back to the older OS X Lion? Or should I improve speed differently?

How do I go back to the older OS X Lion? Or should I improve speed differently? Would improving memory to 8GB help?

Wi-fi problems in me new macbook pro 13 late 2011

hallo aim having problems with the wi-fi in me new macbook pro 13 late 2011, it seams to always be log on and off and i can't get a stabled connections other divides in the house work fine with the wifi(pc etc..)

If the MBP was purchased within the last year take it to the Apple store
or contact Apple. There are few threads in this site dealing with the same issue.
There is no single sure shot step to correct this problem.
May be you can go through those discussions and find a solution.
Best.

Severe wireless problems; MacBook Pro 13inch Early 2011

I just installed updates on my MacBook Pro 13inch early 2011. I now have severe problems with my wireless. What can I do to undo the updates? One of them was a firmare update.

There is generally no need to undo the Updates, just Re-Do your wireless setup:
System Preferences > Netowrk > WiFi > ( Assist Me ) ...

Be sure to specify a new Location.

MacBook Pro 15" Late 2011 Problems with iMac 27" Late 2009 TDM

Hi,
I just got problems with my iMac 27" Late 2009 (Mini-DisplayPort) and my MacBook Pro 15" Late 2011 (Thunderbolt).
When I try to use my iMac as external monitor for my MacBook, there are massive glitches and graphical bugs on my second screen.
I bought a MDP-to-MDP wire from Belkin which works perfect on other computers.
I tried these things:
- Disconnected MagSafe from MacBook + unplugged all USB devices + switched graphics to discrete.
- Shut down all computers ... then booted MBP, iMac and triggered CMD+F2
- SMC, PRAM reset on both devices
The cable works, because:
17" MacBook Pro Late 2011 works perfectly on my iMac screen with my Belkin wire!
I connected my MacBook Pro 15" to a 27" Cinema Display and it works flawless.
After that I plugged it out and tested it again with my iMac screen -> suddenly it works.
Retriggering CMD+F2 or replugging breaks it again with massive bugs.
The MacBook Pro 17" is on 10.7.2, 15" is on 10.7.3, but I also tried to trigger dual screen in 10.7.0 setup with the same issue.
Maybe its a problem with the internal 6750M of my MacBook Pro 15"?
The 6770M of the 17" is working well.
Sample Video:
http://www.youtube.com/watch?v=W_pgc52syes
All updates/firmware updates of iMac and MacBook Pro are installed.
Any solutions?
Greets,
Kai

Macbook Pro 13" (Late 2011) - High Definition Audio Device - Code 10

Hi, i installed Windows 7 Ultimate 64 Bit via Boot Camp on my new Macbook Pro 13" (Late 2011). Driver Disk was installed, but the "High Definition Audio Device" couldn't be started. Status is Code 10. Normal Cirrus Logic Audio is working. Any advice, how this could be fixed? Would be nice, to have audio over the Mini-Displayport HDMI Adapter on Windows as well (Works perfectly with Lion).
Thanks,
Thorsten

Macbook Pro 17 Late 2011 vs Macbook Pro 13 2012

Hey
I have a Macbook Pro 17 Late 2011 model, its works like charm but my onyl problem with it , its too big for me , i travel a lot and its not really good for portability. I use this mac mainly for coding and developing and playing WoW (in BootCamp) but i play nothing else. So my friend said he is willing to buy from me and i decide to get a new macbook pro but the 13" for portability and its also fair enough for coding but im afraid thats its not enough for playing WoW. My friend pay me 1800€ and i found a brand new Macbook Pro for 1050€ + 300€ (for 256gb ssd and 16gb ram) so its gonna be a fast machine but maybe still not enough for WoW. What should i do?

The 17" model is one of the last that supports Express/34.
Thunderbolt does offer more expansion options, but at additional cost.
Make sure the 13" model you get has built-in optical drive unless you don't use it.
Make sure any games you develop for support the graphics card of the machine you end up getting. If they don't, don't expect them to magically work on your machine.
I typically have found the recommended graphics card is the only one that works. Minimum graphics card may at random not work, unless you do no multitasking with many games.

My macbook pro 13inch late 2011. The WiFi has stopped working.
