The key is that you must enter your network password in HEXADECIMAL into your TiVo. You must do that even if your Airport Express password is basic, old alphanumeric text. You do NOT have to change your passwords on the Mac or the Airport Express to get this to work. But TiVo, for some reason, requires that you give it the hexadecimal equivalent of your password to hook up to Apple wireless network. For those of you out of the loop, AE is the new little card deck size, portable wireless base station from Apple. I purchased the adapter that TiVo recommends--the Linksys WUSB11 Wireless-B (though TiVo's site confusingly lists different software(?) versions). I plugged it in, and my TiVo Series 2 unit immediately recognized the Airport Express network I use to connect to the Internet, listing it by name. But you still have to configure your TiVo by telling it the network's password. Here's how to find the hexadecimal equivalent of your existing network password. Open the AirPort Admin Utility on your Mac (your airport network should show up in the list), click on the Configure button in the tab bar, that opens a window of network settings, then click on Password in the new window's tab bar at the top. That will open an alert box that gives both your regular text password and the hexadecimal one. You can even select the hexadecimal password (hold down your mouse button and drag across it) and then copy and paste it into a word processor for printing out. Take it to the TiVo and under the network settings, you can enter your password. (You do not have to do anything with TiVo's TCP settings.) Here's the TiVo menu sequence. Select Read New Messages & Setup ---> Settings ---> Phone & Network ---> Edit phone or network settings ---> Wireless Settings . It will give your directions, then continue, and your network should show up. Select it, go right, and then you'll be prompted for the password. Just be sure to select HEXADECIMAL! If it works, you will get a message indicating that TiVo has successfully located the network. If not, you probably selected the wrong characters. After that, you should be all set. If you go back to the Phone & Network Settings page, you'll see on the upper right side, your wireless information--name of network and signal strength. That screen is also where you can Change connection type from Phone to Network to TiVo's calling home. The TiVo on-screen directions, manual, and web site really should highlight the hexadecimal requirement for Macs and explain how to find the equivalent of regular passwords. Hope this post saves others time, trouble, and frustration. And lets others know that Airport Express works great with TiVo!
