Although the AP has both 10BaseT Ethernet and RS232 serial connectors, the serial port doesn't appear to be functional and it's not documented in the User manual.
Configuring the AP can be a one or two-step process. The AP comes set up as a DHCP client, that is, it will pick up an IP address from a DHCP server on your LAN. As long as you have a way of finding out the IP addresses of DHCP clients on your network, you'll be able to see the address of the AP, and enter it into your web browser to connect.
The AP is protected by both a user name and password, which are documented on the Quick Installation card that comes with the AP.
If you don't have a DHCP server, then you need to use the WLAN AP Utility. You install the utility from a floppy, and launch it from a Windows 95/98/NT/Me/2000 machine. With the utility, you can:
The utility quickly found the AP, which appears to come up with an IP address of 0.0.0.0 in the absence of a DHCP server. (If it's not found, get out your bent paper-clip and press the hidden reset button on the rear of the case.) The Utility then assigns a temporary IP address that is in the same subnet as the computer that you're running the utility on. At this point, you can connect with your web browser and set permanent IP address info (and disable the DHCP client feature), and set the other AP parameters as needed.
The browser-based Management Utility (click on the screenshots below for a full-sized view) is nothing fancy, and I found it a little buggy. I kept getting sent back to a screen that told me "Another user has logged in./The login has timed out./ File not found. Please re-enter" after I tried to apply changes.
Update 12/19/00 SMC says these bugs are fixed in the later firmware available here. The newer AP firmware also lets you set the WEP key via passphrase or manually.
I also found differences in display between Netscape 4.75 and IE5.0 that ranged from annoying to misleading (see WEP section below).
The AP and its companion SMC2632W 11Mbps Wireless PC card are not shipped with compatible channel or (E)SSID names. So at minimum, you'll have to change the settings on one or the other so that they're the same. Neither manual tells you to do this, however! (See this page for help.)
Update 12/19/00 SMC says that you don't need to worry about setting the PC card channel when using it with an Access Point. The PC card driver will scan for Access Points and connect to the closest one.
Documentation was pretty basic and you'll probably find yourself wanting more information. SMC's Web site has manuals, AP firmware, and the AP utility available here. If they're as good as they've been in posting new Barricade router firmware, you should probably check to see if they've posted newer versions than those that come with the AP.
