As the maintainer of the Mobile Mac Weblog, one of the things I get to do is upgrade mobile hardware. A while back I showed you how to upgrade the hard drive in a Mac Book Pro, or even install a second hard drive. In this Macworld video, I demonstrate the process of upgrading an older MacBook Pro’s 802.11g wireless card to a new, faster 802.11n version. I also cover the kind of performance gains such an upgrade will bring you.

The new wireless card I installed is FastMac’s AirPort Extreme 802.11n Wireless Card ($90); I used the version for the MacBook Pro, but FastMac sells kits for most recent Macs.

To test my wireless signal before and after installing the upgrade, I used Chimoosoft’s handy—and free—AP Grapher, which lets you monitor and measure wireless networks.

I mentioned Apple’s AirPort Extreme Base Station; you can get more information about this wireless router in Macworld’s review of the AirPort Extreme Base Station with Gigabit Ethernet.

For more information about the differences between 802.11g and 802.11n, check out Apple’s 802.11n page.
