A C2PC made 04/12/2007 adds a heatsink, changes the power adapter, and changes the WAN port color from black to blue.

"790BR102201Q" is silkscreened on the board of one G125 (w/ heatsink + blue WAN port). This Quanta P/N would seem to indicate this board designation is BR102.

The single radial capacitor on this G125's board is from TAICON.

The default SSID is the MAC address printed on the label on the bottom of the unit (with upper case letters).. an example of such would be 0016019ACBA0.
