On Thursday I picked up a shiny new MacBook Pro. Having been a Windows/Linux guy for, well, ever (not counting all that DOS stuff), it’s been an interesting experience.

One negative that I ran into was very slow wireless connectivity. Being that we have two other computers, an iPod Touch and my XV6700 all connecting over the wireless at fast speeds, I suspected something with OSX.

The first solution I came across said to disable IPV6 connectivity. System Preferences -> Network -> Airport -> Advanced -> TCP/IP and set the Configure IPV6 to Off. This worked well at first.

Then I noticed things being slow, almost like it couldn’t connect. Clicking on the wireless icon in my status bar I saw that it was constantly going from Aiport: On to Aiport: Scanning. I tried changing the DNS servers to OpenDNS, which also helped a little, but still nothing.

I was just about to switch to a USB Wireless dongle I have when I happened to click on the Location dropdown in System Preferences -> Network. I added a new location (called Home), bumped up Airport to be the top-ordered connection (by using the Set Service Order option – even though Airport showed at the top of the list, I made it the top in service order) and applied the changes. This reverted the above changes, meaning I didn’t change the IPV6 or the DNS Servers, but so far even though the status keeps switching to Scanning, my internet experience has been nearly flawless.

Hope that helps someone else!

    thank you! After failed attempts this is what worked, but I had to set IPV6 to automatic.
