Where can I find my MAC address on my PPC ?

The MAC address is a 12-digit hexidecimal number. Most Compact Flash network cards have the MAC address printed on the card, in some cases it is listed as the serial number. It can be found in the Dell Axim X3i by enabling the wifi, select Start, Settings, Connections (tab), Dell WLAN Utility, More Info under Station IP Info. The Mac address and Device Name are the bottom two items. On the X30, Start, Settings, Connections (tab), Dell WLAN Utility, Advance (tab), Network trouble shooting, Advanced button. On the X50 and X51, open the WLAN and select the Advanced tab. On iPaqs with built-in wireless, look at Start, Settings, System (tab), Asset Viewer, Wireless LAN.
