Early 2011 MBP Wifi connection issues

I have an early 2011 i7 Macbook Pro (2ghz), and tonight my internet stopped working. Then I noticed my wifi had died. So I restarted the router. Didn't fix it. I then restarted the mac. My wifi came back. Then it died again ... and I restarted the router and the mac multiple times. Then I tested on my iPhone (disabled 3G and just used wifi) and it worked fine.
Been doing some checking online and it looks like my Mac may be broken. After all my ranting about how great it is! Anyone got the same issue or a fix? Or do I once again have to take this machine to the store for another checkup? Sick of my Apple hardware having problems. Had 3 iPhone 4's !

1. Check the cycle count of the battery against the rated life for your model. The battery may be due for replacement. If the power adapter is connected almost all the time, the battery may need replacing even though the cycle count is not too high.
2. Follow these instructions, or these for OS X 10.8 or earlier.
3. In the Energy Saver preference pane, uncheck the box marked
Enable Power Nap while on battery power
if it's shown (it may not be.)
4. You can also try resetting the SMC.
5. Make sure your system is up to date in Software Update.
6. Make a "Genius" appointment at an Apple Store, or go to another authorized service center.

New MBP wifi connectivity issues

Recently bought a new MBP about 2-3 months ago and I've noticed almost the entire time I've had it I have always had issues with the wifi constantly timing itself out. I know for a fact that this is not related to my router or ISP as I have other computers on the same network that don't run into these issues. This computer has also been tested with the same results on other wifi connections. I am currently using OS X 10.8.2 on a 15in, mid 2012 model. This issue is very frustrating. I notice this issue during everything I do from Online computer games (WoW) where the connection will just drop to basic web page browsing such as navagating to this page which was a task in itself. I constantly have to turn the wifi off and back on again to refresh the connection and to load web pages.

Same problem, no solution yet!

Early 2011 MBP "Replace Now" Issues

My early 2011 MacBook Pro recently stopped working without a charger, which I realized was because the battery indicator said "Replace Now". Otherwise, it ran more or less the same but started to get slower as I used it. Today, it became unusable, with applications like Safari taking up a huge chunk of processing speed. After powering down, it won't start up anymore. I tried to boot to disk utility and it said my disk needed to be repaired. Everything was fine with my HD before the battery failed--is there any way that the battery level could done damage to my disk?
I have a new battery coming on Monday, and am praying that when I replace the old one, everything will be back to normal. Could anyone shed some light on this issue?
Thanks

Early 2011 MBP 13" Performance issues??

I recently install a new samsung 840 Evo 240gb SSD and upgraded RAM to 8gb... the performance is fantastic but its lacking in the battery department. Is the battery getting beat up by the SSD or is there an underlying problem i missed?

AMD Radeon HD 6750M, Early 2011 MBP, 10.9.4 Problems

Hello,
Ever since 10.9.3 update I have a serious problem with my Early 2011 MBP with AMD Radeon HD 6750M card.
First my configuration:
MBP 2.2 GHz Intel Core i7 (Macbook Pro 8,2)
16 GB RAM
512 GB Sandisk SSD and 750 Stock HDD
AMD Radeon HD 6750M and Intel HD Graphics 3000
OS X 10.9.4
I'm usually using my MBP with external display with a resolution of 1920x1080. The display is connected via DVI to Mini Display Port adapter. When I connect the external display, my MBP switches to the AMD card. Here's where the problems begin. If I'm using Davinci Resolve, Capture One Pro or any other software (that I use regularly) that uses the GPU extensively, the cpu usage will rise, the computer will start to feel sluggish and my productivity almost becomes none because even the simplest tasks such as opening another tab in firefox or safari takes anywhere between 1-3 sec. When the computer starts doing that, I cannot play a simple HD video at native fps and the whole machine basically becomes too expensive paper weight. The strange thing is that even after I quit all programs, the system cpu usage continues to be high, around 50% with kernel_task being the star using all this cpu and it keeps using all of this cpu forever, at least until i shut it down or disconnect the external display and manage to make it switch to the internal Intel gpu.
The problem started after istalling the 10.9.3 update and it's still there with the 10.9.4 update. I even formatted the computer and reinstalled everything but the problem still persists.
I haven't experienced anything like this on 10.9.2 and the machine was actually quite fast before that. Now, I have too expensive paper weight on my desk.
Since the problem is very specific, I doubt many users will complain and I doubt Apple will ever do anything to fix it, at least until hopefully the new drivers in 10.10 fix the issue hopefully.
My question is:
1. Has anyone else experienced this and managed to solve the problem?
2. How can I downgrade to 10.9.2? I don't have time machine backup but i have bootable usb with 10.9.2. Will it help?
All best,
Goran

Early 2011 MBP 17 Random Shutdown and Battery Behavior

Hi all, new to the forums here.
I recently purchased a refurbished early 2011 MBP 17' 2.2 Ghz i7 with 8gb and 10.7.5. Out of the box, machine looked great, but I noticed that the power cable was different than the one I had for my early 2011 MBP 15' I have for work. This raised an immediate redflag (buying from a refurb site outside of apple is always a cause for concern IMO) so I abstained from using that charger until I knew a little more. I plugged in the machine and booted it up and everything worked great. The batter was close to 100%, so after charging for approximately 20 min, I unplugged it, and the laptop immediately died. I powered it back on, and the harddrive began to spin for a few seconds, then the same result, total loss of power. Started up again, and I was able to boot into OS X and play around for a bit for a period of time before again, shut down.
For the next few days, same story. I was able to at one point, drain the battery completely and do a full cycle charge. The first time I did this, no change in behavior. Again, a few days later, I was able to drain the battery and perform a full cycle charge, but this time, a major change in behvior. Since the second full cycle charge, I have had absolutely no power problems. I haven't really "pushed" my MBP to see if fully utilizing the CPU/RAM/GPU will produce the similar results I had early, but it appears that everything is working great.
Here a few interesting notes to my situation.
When I was first operating the system (when plugged in, there were no shutdowns, only while on the battery) I pulled up my system report, and noticed that my battery cycle was very low (~5). This seemed odd, because I had opted for a used battery instead of a new one.
Prior to reinstalling Mountain Lion, my volume up key would trigger a few strange events. The screen for briefly get quite bright, then all open applications + the doc and widgets would restart (similar to killing explorer.exe in the windows task manager).
Since performing the fresh install, I have had abslutely no issue with my MBP and I love it, its a beautiful machine. However, as I purchased refurb, I'm hesitant to proceed (I will exceed my return period in ~2 weeks) without knowing my machine is in prime working condition. I have read issues about early 2011 models having issues with batteries and GPUs, but my symptoms were dissimilar to those described by others with those particular issues.
Any thoughts?
I have a genius appointment tomorrow evening for a general diagnostics check, but if others have experienced these issues, I would appreciate some input.

Can't install windows 8.1 on early 2011 MBP

Hey all,
I'm having problems installing Windows 8.1 on my Early 2011 MBP (MacBookPro8,2). When my superdrive died I installed an SSD for the boot drive and kept the original hard drive as a secondary drive. I used BCA (modified to support USB) to create a USB 2 Windows 8.1 install drive from an ISO I previously created. I also had it partition the hard drive. When it reboots I get the "no bootable device found" and blinking cursor issue. I've tried holding down option and choosing EFI, but i've picked up during the last week that installing through EFI on my MacBook Pro isn't possible. Does anyone have any ideas on how to solve this?

I ended up coming across this last night:
http://malwaretips.com/threads/installing-windows-on-a-mac-with-a-damaged-superd rive.32474/
I am in the process of testing this out, but currently I'm stuck with an issue with winclone not expanding the image of the usb install disk to use all the space in the partition. However I did boot into the Windows installer and didn't run into the "couldn't find partition" , "no bootable disk", or "not an MBR" errors I've seen before.
I Think the key for non supported hardware and Windows 8 or later is to create the bootable usb in windows and not through BCA. I actually used the VMWare Fusion trial and a windows 10 technical demo image to do the monkeying around in windows. Hope this helps someone else. I'll keep updating.

What's wrong with my macbook pro (15" early 2011) when i connect it with TV via hdmi

What's wrong with my macbook pro (15" early 2011) when i connect it with TV via hdmi

Hello Alex,
It sounds like you are getting excessive CPU usage when connecting an external display via HDMI to your computer. I would try the troubleshooting steps outlined in the article named:
Apple computers: Troubleshooting issues with video on internal or external displays
http://support.apple.com/kb/ht1573
When using an external display be sure to check the following:
If you're using an Apple notebook, confirm the AC power cable or adapter is securely connected to the computer and the cable providing power to the display is also secure. It is always good to have your notebook connected to AC power when an external display is in use.
Confirm display adapters are fully seated in their respective connections and that they are supported models and for the computer and display. Refer to these articles to assist you with adapter compatibility and further configuration information:
Monitor and Display Adapter Table
About Mini DisplayPort to HDMI adapters
Apple Mini DisplayPort adapters: Frequently asked questions (FAQ)
Thunderbolt ports and displays: Frequently asked questions (FAQ)
Remove all display cable extenders, KVM switches, or other like devices and retest to determine if the issue is resolved.
Try unplugging the video adapter or cable and then plug it back in.
If more than one video adapter is in use (or "daisy-chained"), troubleshoot by using only one adapter.
Example: A mini DisplayPort to DVI adapter connected to a DVI to HDMI adapter is an unsupported configuration because there is a series of adapters in use.
If available, try using a different display and or adapter (or use a different connector by using DVI instead of VGA, for instance).
Reset the systemYou can reset the Mac's parameter RAM and SMC.Reset the resolutionStart by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
Start up in Safe Mode.
From the Apple () menu, choose System Preferences.
Choose Displays from the View menu to open the preferences pane.
Select any resolution and refresh rate that your display supports.
Restart your computer.
Thank you for using Apple Support Communities.

Sterling

Early 2011 MBP Slowing Down

Hello, I have an early 2011 MBP (15-inch), system report below:
MacBook Pro (15-inch, Early 2011)
Processor: 2 GHz Intel Core i7
Memory: 16 GB 1333 MHz DDR3
Startup Disk: Macintosh SSD
Graphics: HD Graphics 3000 512 MB
Lately, my MBP has been slowing down a lot.
I tested out a bunch of flash sites, but it does not seem to be the problem. Like I said, I have 16gb of RAM (combined with what I have located above, i7, etc), and have had numerous flash sites up, but no slowdown. The problem is recent, in that I've noticed it in the past 6 months. Nothing changed in that period at all to cause this problem.
I've run this setup for a couple years without issue (SSD where the DVD player used to be, and the HDD where the old HDD was located), without issue.
My MBP gets so hot that I have to move it frequently for scare of erythema eb igne (stupid technical term, but I might not be joking, and would rather not joke around about something like that.but seriously it get that hot where your only option is to shut off the MBP. I know that might sound extreme. But my MBP gets that hot. Especially if you are running a program like Premiere. I understand the power and RAM that it takes to run a program like that, but it was shocking. This is a program (Premiere) I ran without problems previously..
Checking activity monitor (and iStat), RAM does not seem to be the issue. CPU seems fine 88-90% usage,
Usually have 7-8GB of RAM available, and the CPU usage under 90%.
I have no idea, but I will be taking a can of compressed air to the MBP.
I was just wondering if anyone had any other ideas or had similar situations to help me out?
Thank You,
T

TS1398 Has anyone had WiFi connectivity issues with their iPhone 5 after accepting the latest IOS 8.0.2?

Has anyone had WiFi connectivity issues at home with their iPhone 5 after accepting the recent IOS 8.0.2 update?

Yes, despite being it an iPhone5 (8.0.2) attempting to connect to an Airport Express.
In my case the iPhone "connects" to Airport Express 2nd generation, but no Internet packages are available; Airport Utility shows the Airport Express as not connected to the Internet; but the iMac, MBP, Motorola phone, Samsung Smart TV and HP printer connect without any trouble.
The actual issue is the DHCP :
sometimes the iPhone gets none, and
when an address is assigned it just doesn't work,
even renewing the address won't work all the times,
switching off and on the WiFi won't work all the times neither,
going on Airplane mode, then back won't work all the times.
Solutions attempted and failed:
Reseting and reconfiguring Airport Express;
Reseting iPhone;
Switching off and on the iPhone;
Setup the DHCP renewal for every 5 days;
Meditation and stark visualisation;
Other possible patch not yet attempted : setting fixed IP addresses
All suggestions received resemble Windows' "Plug & Pray"
I gave up after reading several notes around the WWW complaining about it.
Last credible suggestion : wait for 8.0.3 or 8.1, whichever fixes the issue first.

HP Slate 21 Pro: WiFi connection issues

Hi,
I recently ordered two HP Slate 21 Pro devices. Unfortunately, both of them have WiFi connection issues. After some time the properly configured WiFi connection will be dropped, which results in connectionless devices. The WiFi AP is disabled after this, and so a timed reconnect will not succeed.
After inspecting the Logcat I found following lines:

That really shouldn't affect it.
I'm a little stumped because I haven't seen this issue with this device before. The only similar issue I found was this, and it's unresolved.
Have you tried doing a hard reboot of the Slate 21?
I work on behalf of HP (But this isn't my job)
