1.3 System Requirements

Release 1.0.0.49 of the Operation Software runs on the 3Com OfficeConnect Wireless 54 Mbps 11g Access Point (model number 3CRWE454G75 / WL-524).
1.3.1 Initial Addressing for the Access Point
The OfficeConnect Wireless 54 Mbps 11g Access Point (AP) receives its initial network address according to the following sequence: 1. The AP boots up 2. The AP searches the network for a DHCP Server to get its initial network address. 3. If the AP detects a DHCP server, it receives an IP address, subnet mask and default gateway from this server. 4. If the AP does not reach a DHCP server, it will set itself to a static initial IP address of 192.168.1.250, Subnet Mask 255.255.255.0. I In some cases, if the 3Com discovery tool (included with unit) does not detect the AP, and no DHCP server is available, the AP has probably defaulted to this address. To communicate with an AP using the default address, follow this procedure: 1. Set the IP address of your PC to any address in the same IP subnet as the AP (for example 192.168.1.10), with subnet mask the same as the AP (255.255.255.0). 2. Point your web browser at the Access Point default address: 192.168.1.250. 3. At this time you will be able to log in and change the operating mode, and change the static IP address if needed.
3Com recommends that you set a static IP address in the Access Point so that you will always know the IP address. Depending on the DHCP server used, a different IP address could be assigned to the Access Point with each reboot.
Release Notes Page 3 of 3
2. Issues Fixed in Release 1.0.0.49 since 1.0.0.44
After the AP lost contact with a remote AP, it could continuously reboot The site survey feature prevented repeater mode working correctly
Under some circumstances, in repeater mode, the signal level would decrease The WDS online help has been improved
3. Known Issues for Release v1.0.0.44
The AP Discovery tool might return multiple instances of the same AP after a discovery. To verify the correct AP is discovered, check the MAC address listed in the table of the Discovery tool with the MAC address on the back of the AP. When using WDS Bridge mode, wireless clients are not allowed to associate to the AP. Only LAN to LAN connectivity, as this is a point-to-point connection. At present WDS does not support WPA encryption. ALL changes to the Setup page must be followed by an Apply on the bottom of the page, to take effect. In addition, after setting Configure Security on the Security configuration popup page, you must also press the apply button on the Setup page, for changes to take effect.

4. Upgrading Software

To upgrade the software in the 3Com OfficeConnect Wireless 54 Mbps 11g Access Point, perform the following procedure: 1. Obtain the appropriate upgrade for your device. The upgrade file available from the 3Com web site may be provided in a Zip or EXE format. If it is, please unzip the file or run the executable to reveal the upgrade file. The upgrade file usually has a file suffix of.fim. 2. Access the AP management interface by pointing your web browser at the IP address for the Access Point. 3. Log in to the user interface by typing the administrator password (Default is admin without quotes). 4. Select the System tab on the menu on the left side of the page. 5. Click on the browse button which will open a screen for you to select a filename to load into the Access Point. Select open. 6. Press the Upgrade Firmware button. 7. Wait until the unit provides the login page again.
