My Macbook keeps disconnecting itself from the internet

Put the router on the roof of your dwelling. i.e place UP Higher. Cisco wireless routers mounted in the ceiling - Macbook Pro 15 i7 connects every time. if airport router - go outside and mount on the roof of your dwelling. Apple engineers getting Fat Dumb and Happy (FBH)

@Bob

I've been using this router for a few years now without problems. As many have stated before nothing else in the house is having connection issues. But the new laptop does from anywhere including the same room as the router.

After reading your many comments I have the same issue.

I have to use my Mac wired to the wall.

Considering the price this is unacceptable.

If a software update is not released soon I will be returning this junk.

Place your router up higher or have a beer

Moving your router to a high location will not work. My macbook experiences these problems on all wireless wifi locations, and it happens less frequently when my Macbook is charging.

I'm convinces it's a hardware problem. I've read some people have taken it in an they swap out an airport card and everything is fine. It must be a bad batch of cards. If it was all MacBooks, i'm sure they would have fixed it by now. We are just a small amount of people experiencing these problems. If it was as easy as a software update, I'm sure there would have been one by now. And any update they make would only be a bandaid, and not a fix, as i've seen some posts where people suggest running a program that continually pings an ip address. This doesn't work either.

I've just whipped my computer clean and reinstalled only the basics using only the disks that came with my machine, and Iwork. So I've eliminated any software compatibility issues such as running VMware or other web browsers. Problem still exists.

My MB Pro has been useless with the internet recently, if it connects at all, it gives up after a short while. It's been going downhill since the battery died - I usually have a max. of 10 minutes charge so am always wired to mains meaning the MB Pro gets hot quickly. Having reset the PRAM today, I cannot get online at all.

The problem is at home, at work and at my parents house where other PC's and Macs work - I am writing this on my new iMac at work, my parents old Dell connects at their house and my three housemates have no problems with their PC's at home. It's often easier to connect when close to the router (ie within 5 meters).

MB Pro details:

MacBook Pro 15" (September 2006)
2Ghz Intel Core Duo (1 processor, 2 cores)
L2 Cache - 2MB
Memory - 1GB
Bus Speed - 667 MHz
SMC Version - 1.2f10
2x 512 DDR2 SDRAM 667MHz

AirPort Extreme (0x168C, 0x86)
Firmware version - 1.4.4

Not really sure what else to put??

Well, I just took my MBP in on Friday. I picked it up on Monday with a new airport card installed. Returned home to find out I still have the problem.
Looks like I need to return to the Apple store tomorrow.

Same problem! I bought my MBP about a month ago, and I love it, I just can't keep it connected to my router. It will disconnect every half hour or so (it varies) and I have to go through System Preferences and diagnostics to reconnect it. My router is WPA2, so that's not the issue. My iPod touch doesn't have this problem, and neither does our older Windows desktop.

I have been having this problem for a while now and have found a work-around that seems to be solid for me. I was dropping my wifi link every 5-20 minutes. I have had zero problems until recently (maybe the 10.6.4 release).

Anyway, I am simply running a terminal window that is pinging my wireless router every 10 seconds. The router address is in the System Preferences-Airport-Advanced-TCP/IP window.

Example: ping -i 10 192.168.1.254

With this ping running, I have not dropped the link once in about 8 hours of work. As a test I have stopped the pings twice and the link went down after 5-15 minutes.

Can someone else try this?

This problem has been driving me crazy, I work with a VPN connection so every time it drops I have to log back in.

This seems to have done the trick for me, thanks very much. It's not ideal obviously but saving me getting annoyed all day.

How can I make a file that runs that line in terminal? I want to be able to just double click is when I startup. I tried to save it as a txt file then remove the extension but it won't run in terminal. My terminal knowledge is pretty basic I'm afraid.

I am having the same problem withmy early 2007 iMac i will be playing a game or sumthing else and it will randomly DC and i have to log out and log bac in its really annoying i hope apple makes a patch for it or something

I've been having this problem too and it's really annoying. I would like to try what you said but I don't really know what that means. Could you please explain exactly what I would need to do?
Thanks!

Try turning off the security settings on your router. This is the only solution I've found.

How would I do that?

Whatever address your wireless router is accessible from (usually 192.168.1.1 but it says on the router sometimes). Go to the Wireless section and find a tab for security. Check to see if it's set to something like WPA/WPA2 and just set it to none and save settings. Try that for a few days and see if it continues to drop connections.

Set it back and see if it comes back.
