Cisco VEN401

Overview
Designed to pair with the Cisco ISB7005 (see also Cisco ISB7005 Wireless Module).
 * Used by AT&T as the AT&T U-verse Wireless Access Point.


 * "WAPB-195N_V03", "ES0-S00-5901R RoHS" is silkscreened on the board in the FCC photos.
 * "WAPB-195N_V03" and "19K-K06-8204R RoHS" is silkscreened on the board shown below.

It would appear that these devices may be using either a BCM4717 or BCM4717V SoC.
 * There may be little (or no) difference between the two..

The default SSID appears to be Cisco_XXXXXXXX where XXXXXXXX is the last
 * four octets of the wireless interface MAC minus one (upper case hex letters).
 * An example SSID is Cisco_4A823669.

The default login credentials are ATTadmin:401!VEN.
 * The device will, by default, request an IP via DHCP.

The power adapter included with the device is an OEM ADS0128-W 120100 (12V, 1.0A).
