My Macbook keeps disconnecting itself from the internet

I also have the same problem. At home, at work, at the coffee shop. The wifi will just ... die. Turning off the airport and restarting solves the issue. Please contact me if there is a fix.

Brand new MBP 13in w/ updates all installed. Just wanted to throw my hat into the pile.

I get "Link down on en1. Reason 4 (disconnected due to inactivity)" every so often. It happens a lot when I'm on Skype.

Sometimes it is Reason 8 (Disassociated due to station leaving)
Sometimes it is Reason 14...

I've tried clearing the pram, deleting all the plists, repairing permissions, changing channels, changing wireless security options, and today I updated my Linksys router with the newest firmware.

This is my first mac and I've been a dedicated PC/windows user for all my life. I can honestly say that even though my PC had its fair share of problems... it could at least connect via wireless without any problems. It is simply embarrassing for apple to claim their computers are superior and then have several threads about how their computers cannot even connect to the internet.

I also posted this msg on one of the other threads as a bump...

Recently my internet provider put in an airport designed for phone usage rather than just computers. This has worked so far. If I had more details, I'd give them, but whatever they did, worked.

Do you mean that you turn Airport off and then on again and this brings you back on line, or do you mean that you have to restart the computer also?

I did both, which is a pain, but I haven't had to do it since the local tech installed a different type of modem.

We had been struggling with both my Mac Book Pro and my wife's Air Mac having random disconnects from our home internet. I traced it to my recently installed Belkin N+ wireless router.

I replaced the router with a Netgear WNDR3700 and our network is once again working fine. I don't know if the Belkin was defective, however, I will assume that it was.

Everything is working just fine now. It was frustrating to troubleshoot as it seemed to me that the router being new should have worked well. Wrong again.

Good luck with your disconnect problems.

I've come on here tonight looking for an answer to the same problem.

I've had my MacBook for less than a month, and ever since I got it our internet connection has been dropping out intermittently. Previously I was on a Dell desktop, and it was connected to the router via ethernet (I think? Is that a yellow cable - I'm not the most computer savvy person).

But here's the catch. It's not just my computer. My husband's Dell laptop is also dropping out simultaneously, as is his iPod Touch.

It will drop out for anything from 10 seconds to a minute, and it will come on again by itself. I reset the router, my husband's spoken with our ISP, both to no avail. The only change has been my new computer, and increased usage because my husband has been home on holidays.

It's driving us a little batty.

I bought a 17" Macbook Pro last week. Brand new, OS X 10.6 - which I updated to 10.6.2, including all the extra updates from the "software update" option. My problem is that I haven't been able to get the Airport to connect with my router. I get an extremely annoying exclamation mark in the airport icon (I have another MBP OSX 10.5.8, no problems what so ever, so I'm 100% the router is not the problem). I tried the following:
1) Reseted PRAM
2) Changed DHCP auto settings to manual
3) Changed wireless channels
4) changed from WEP to WPA, and also I tried with an unprotected signal
5) Reseted router, MBR, turned on/off airport, did a new location, etc.
6) flused DNS cache
7) Deleted the com.apple.internetconfigpriv.plist and com.apple.internetconfig.plist files from ~/Library/Preferences
8) Removed all files within ~/Library/Preferences/SystemConfiguration/ and rebooted.
9) Run the hardware check utility, and it's not a hardware issue according to it
10) Reinstalled OSX!!!!

Nothing has worked. I'm completely out of ideas... thanks

here is a sample of the problem

I'm experiencing the same problem on a MBP (stats below) less than a week out of the box. Noticed it more on 3rd party wireless networks, not so much on my Airport Express at home. Would hate to return this laptop just for this problem but it is a big deal.

I just watched your video, and that's the same problem I'm having with my MBP purchased just before Thanksgiving. I've had the problem from the start, and I'm using a 2Wire DSL modem, which was purchased back in September.

I've followed several tips from the discussions here, and nothing has been a complete fix, although it does seem a bit less frequent than before.

Sometimes it happens 5 times in 10 minutes, other times it won't happen even once during a 3 or 4 hour session. Very frustrating and confusing.

Since not every MacBook Pro seems to be experiencing this problem, I think its a combination of software and hardware. Perhaps a specific factory got a hold of a bad batch of a certain component, and not every one of that component was affected, and we are the lucky (unlucky) ones. To see if we can identify a trend, I'm including my MacBook Pro info.

P.S.

I've been online for over a1.5 hours and no drops. Go figure.

I am having the same problem with my 2 year old MBP since I upgraded to 10.6. This setup worked flawlessly for many months until Snow Leopard.

I have tried applying the patch but it only fixes the problem temporarily.

The only workaround I have found it to change the SSID (name) of the WiFi and reboot the modem (in my case an Actiontec from QWEST). Then connect to the new SSID and I'm back in business (for a while) ... sometimes days sometimes only hours.

I make me think that for some reason the SSID and Password are getting corrupted.

FWIW, my iPod Touch does not show any of these symptoms.

I'm having the same problem, it's really bugging me!
I bought this MBP15 on the first days of November...very bad luck, the first one they sent was factory-scratched and yes, in the few days I own it I have experienced the same disconnection problem...I sent it back and now I've got another one (at least, the case now is perfect).
I have disconnections using both ethernet or wi-fi connection..on wireless is worse, it's almost impossible to do anything (I have to turn on and off airport on mac to reactivate connection).
My router is a Netgear DG834G rev.3, I tried also with a Fonera. Static IP or Dhcp, with encription or without. Everything else connected to this equipment is working good, I have an ibook and an ipod touch with network perfectly working at the same time while the macbook fails.
I noticed a strange behaviour of the thing: not all services are affected at the same time. For example, it can disconnect the im (adium) and leave mail running, or viceversa, or have in one tab of safari a streaming video running, then open another tab and get the internet connection error (while the video is still going, and continues to download).

I don't really know what else to do, it's driving me crazy
