Every wireless router and AP has MAC address filtering. But the WAP321 goes a step beyond with Access Control Lists (Figure 8). Up to 50 rules can be created to allow or deny access to clients based on IPv4 (shown), IPv6 or MAC address parameters. (There are no user based controls.)

If your devices don't support 802.11e, don't despair. The WAP321 has a complete set of diffserv based controls. I'm always at a loss to even get started at configuring diffserv.
But the WAP321's implementation is clear enough that I think even I could get some useful diffserv-based QoS working! That said, it would certainly help if the Admin Guide had some examples, in addition to its complete description of each control. Check the gallery for all the screens.
The last, but not least, feature that will probably sell a lot of WAP321s is the Captive Portal. This would be used for hotspot or other applications where you want to put a level of authentication, or even just an advertisement between your user and general Internet access or redirect them to a "walled garden" website.
You can create two CPs, each with its own verification methods. Each instance has a very complete set of parameters (Figure 9). Note that you can even limit up and down bandwidth and authenticate as a guest, to a user/password database stored on the WAP321 or a RADIUS server.

CPs can be assigned to any or all of the 8 virtual APs (SSIDs) and you can upload your own portal page, or modify the built-in one (Figure 10).

The built-in user database supports three groups and 128 total users. Each user has a password, away timeout (0 - 1440 mins), and max/min bandwidth (0-300 Mbps). Report screens are also provided for current users and failed authentications.
I tried a simple user-authenticated portal and got it to work on the first try!
I should note that the online help is generally excellent, containing helpful explanations and definitions as well as control descriptions. Check the gallery for more screenshots of key admin pages and further commentary.
