depends on how much you want to route between LAN, DMZ, and wireless. 
10 Mb of Internet bandwidth isn't an issue at all, but if you want
that plus ~100 Mb between LAN and DMZ, and ~30 Mb between wireless and
LAN, then no, a 4801 is not sufficient.

You can get a maximum of about 45 Mb thorugh a 4801.  take off 5 Mb
for Internet, and you have ~40 Mb of capacity between the LAN,
wireless, and DMZ interfaces.

granted this will vary some depending on environment, but that should
be a pretty accurate estimate.
