Now, back to disassembling the chassis...

A simple tug removes the Ralink-based RT2571 USB Wi-Fi dongle.

The Ralink RT2571 supports both USB 1.1 & 2.0 for 802.11 a/b/g connectivity.

The chipset has the capability to operate in Windows XP, 2000, ME, 98SE, and in Linux.

Considering the open source nature of the chumby, wireless internet can conceivably be sacrificed for the extra USB port housing the Wi-Fi dongle.
