It was added in some past firmware update and apparently never made it
into the manual or data sheet:
<http://whirlpool.net.au/index.cfm?a=h_view&model_id=181>
<http://www.speedguide.net/broadband-view.php?hw=19>
Just search Google for "SBG900 WPA" and you should get plenty of hits.
Argh, the Motomorons buried it. See:
<http://broadband.motorola.com/consumers/products/SBG900/downloads/SBG900_Data_Sheet.pdf>
Just above the line with WEP, it spells out "Wireless Protected
Access".

True. It only appears next to the boxes that Comcast does NOT support
the wireless section. If that's acceptable, you have a very large
list to search. Sorry, but it was the best list I could find. The
rest, you have to do some digging.

Conglomerated units tend to be a compromise. The router sections are
insipid compared to what can be found in a Sonicwall, Cisco, or even
high end commodity router. For example, I've noticed that most have
either limited or no QoS for VoIP, no WDS support, and limited
diagnostics. Upgrades to the modem sections are often problematic.
For example, if we ever get DOCSIS 3.0 in the area, most of the
existing modems don't have sufficient horsepower to handle channel
bonding and such. As new wireless acronyms arrive (MIMO, roaming,
WMM, etc), upgrading the wireless section may also be problematic.
This is usually done by replacing just the wireless access point to
add acronym support, but impossible with a conglomerated unit.
Location is my main objection. The modem and router want to live
somewhere near the floor, where all the cables and wires come
together. However, the wireless works best when the antenna is
elevated to above the furniture clutter, such as on a bookshelf.
Putting the conglomerated unit on a shelf or desktop will work, but
you have to drag the wires along. My favorite form of security is to
just turn off the wireless section. That's easily done with an access
point, but not so easy with a conglomerated unit. Of course, if you
decide to switch to DSL, the entire unit is useless as you can't use
the router or wireless with an external DSL modem without access to
the inter-section (ethernet) ports.
This lack of inter-section access also causes me problems with
monitoring. I like to monitor traffic on the WAN side of the router,
to see what users are doing and what attacks are being dropped. That
can't be done with a conglomerated unit as there is no easy way to tap
the traffic. (JTAG port will NOT work for monitoring).
In case of a failure, it's much easier to troubleshoot (by
replacement) with 3 seperate sections.
I will admit that there are benifits. It's easier to monitor the
modem diagnostics in a conglomeration as the internal web browser has
access to everything. One device setup instead of three setups are
obviously simpler. Cost of usually less for a conglomerated unit and
often subsidized by the cable company. Of course, there's only one
wall wart to add to the rats nest behind the TV and computah.
