Clear (formerly Clearwire) is actively rolling out their WiMax service and I was lucky to get my hands on a demo unit to test. Installation is a no-brainer. One thing I was told was to download the driver from the Clear.com website. Of course this assumes you have a pre-existing Internet connection. I had to do this because the thumb drive that comes with the unit had an old version of the driver. Once downloaded, I disconnect from my Internet connection, plug in my Clear modem and launch the Clear Connection Manager. The connection manager finds the modem and connects. It's that simple. So the first thing I do is run a speed test. This TWTelecom site provides servers in Honolulu and Los Angeles. As you can see the download speeds from LA are quite impressive. I also tried the Honolulu server and surprisingly had a slower download speed of about 6.4Mbps. Both uploads were similar. I'll leave it running to see how it fairs. One complaint, the drivers for the WiMax modem supports Mac OSX 10.5 and 10.6. I have a laptop running OSX 10.49 (Tiger, PowerPC). So I am out of luck for my PowerBook (albeit old). Drivers are also available for Windows XP, Vista and Windows 7.
