For a list of all currently documented Broadcom chipsets with specifications, see Broadcom.

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).

Additional external links

however, it appears to brick (at least some) units and require recovery via CFE.


There are two screws holding the case together underneath the label.
