My Macbook keeps disconnecting itself from the internet

I've got a 2 week old MB Pro Retina. Same problem and it's even running 10.8. I had the same problem on all my macs. TURN OFF YOUR WIFI ON YOUR MOBILE DEVICE! Works every time no matter what Mac or OS I am running. It's a wifi conflict. Not your apple hardware! Hate how people bash companies cause of their ignorance.

I hate to contradict you, but I have all of my WiFi devices connected including my mobile devices. The problem did not go away here until I purchased an Apple router. I tried every other suggestion in every thread with this subject (numerous) and the ONLY change that made a lasting difference was to abandon my Cisco router for an Apple router. The upside is I now have a 2TB backup drive for Time Machine.

Oh no worries. Don't sweat the contradiction. Here's what I've concluded. Over the last year I've been running this. I have an ATT Elevate Hotspot as my connection to the internet. I have a Time Capsule, an iPhone and 3 MacBook Pros, 1 a late model 2010, another a late model 2011, and a 2012 macbook pro retina. Each running 10.6, 10.7, 10.8. ALL of them experience the same problem of wifi issues. So I've concluded it's not Apples problem. It's a wifi problem. You could be right, perhaps the Time Capsule is causing wifi issues. I have found that when I turn off the wifi on my iPhone, ALL of my macs connect with no problem and stay connected. It seemed to me that the iPhone wifi was causing some wifi problem. For whatever it's worth right, or wrong, it's not Apple MacBook problem, cause I have 3 different models. It was always when my iPhone was trying to connect over wifi. Once I turned off my wifi on iPhone and iPad, I never had issues. So, for those that throw a fit over the Apple hardware, it's not that. I strongly feel it's a wifi interference issue. That's what irritates me, is people just start bashing the maker with their ignorance of the technology that plays a part that they have no clue about.

So, I have a 4 year old (or so) iMac running 10.7.4 and lately it has started dropping the network connection. The difference is that I'm NOT using the wireless to connect to the network - old fashioned Ethernet - and the only way to regain my network connection seems to be to re-boot it. This has just started happening the last week or two so wondering if it was some recent software upgrade causing my problem?

I got my macbook pro last summer, and only in the last few weeks it has started randomly disconnecting from the internet, both using the wifi on campus and in my apartment. I have bootcamp on my mac and can run Windows XP, and it does the same thing on the Windows OS. It's not a software problem, it's a hardware problem. Any help?

I like your solution to this widespread problem (I've tried everything, nothing helped, recently brought my book pro to a repair depo, and they going to change my wireless card now), but what apple should have done, is to post the advice like you just did :))

Or better yet, put some detailed instructions/troubleshooting in their beautiful, square, white and semi-empty booklets that come with the device. Because some people don't buy apple plan.

----I see folks posting some Good solutions for their home routers etc, but what if I am using a wifi at the cafe or elsewhere? If I am lucky to connect at all in the first place, it drops in less that an hour (and i can't get back in).----

Sweet. Thats the only thing that worked for me, thanks!

Changing the channel of the router from the factory set 6 to 10 fixed my problem.

Internet was dropping every 5 minutes and I had to turn my airport on and off to get it back. Tried most other solutions but nothing until the channel change idea and now it works perfectly.

Try it.

thanks

Changing my router channel from Channel 6 - 2.437GHz to Channel 11 2.462Ghz is working for me so far. I was about to take it to the apple store. Was working fine on Channel 6 (default channel) for 2 months since I got it. Mid 2012 MacBook Pro, then it just started cutting in and out. Hopefully this changing channels fixed it for good. Was happening every 5 minutes now its been 10 so im still good haha.

If you disconncet from Cafe wifi try to reset you WLAN settings, sometimes the network setup at the cafe has a time limit per computer. Always worked on my iPhone. Can't trick a trickster.

I had a problem similar to many where my MacBook Pro 17" 2010 is working fine on the wifi, then all of a sudden it drops the connection. I would go into Network Preferences and try to turn on/off the wifi, but the Wifi would not be able to be turned back on. The only solution was a restart, which allowed it to work for sometimes seconds, sometimes minutes, sometimes an hour.

I did a clean reinstall, and the problem persisted so it was not a software issue (10.8.2). I went to the Apple Store and got my Airport/Bluetooth flex cable changed which seemed to be the issue. It is most likely a hardware problem that you all are experiencing if your story is similar to mine.

I tried everything suggested throughout this thread and after a complete reformat did nothing to help, it dawned on me to try a wifi usb adapter. I've been using one I bought on Amazon for $9 for the past 7 months and it has worked flawlessly on every network I join and hasn't dropped my wifi connection once. Best $9 I ever spent after the year of frustration using Airport.

This is so anoying... I am so disappointed from Apple... this MAC wont stay connected 10 min. It does not happen with my other PCs or Ipads

Rachel,

great post. I tried many all different things to get my 2008 macbook pro to stay connected to the internet. In short I figured I'd spend the $10 to see if a usb wifi adapter would fix my problem, and sure enough it did. Everything has been working perfectly since I installed the usb wifi adapter - computer downloads more quickly, no drops in internet service, and airtunes is working as it should. Great solution, thanks!
