What to do if the Setup Wizard does not detect your

Access Point

Be sure the Access Point has finished booting
If you run the Setup Wizard before the Access Point has fully booted, the application may not be
able to find the device. During its boot-up sequence, the Access Point tries to get an IP address
from a DHCP server on the network. After 2 to 3 minutes of trying unsuccessfully, the Access Point
sets itself to use the factory default static IP address of 192.168.1.250, subnet mask
255.255.255.0. Sometimes the default IP address will appear in the Setup Wizard just before the
proper DHCP-assigned address is set. If opening the web browser to manage the Access Point is
initially unsuccessful, try running the wizard again to get the proper address.
Be sure the Access Point and your PC are on the same network
The Access Point and the PC must be on the same wired network and subnetwork for the Setup
Wizard to be able to detect the Access Point.
Connect to the Access Point manually
During boot up, if the Access Point does not detect a DHCP server after 2 or 3 three minutes, it
will assign itself the factory default static IP address of 192.168.1.250, subnet mask
255.255.255.0. To communicate with the Access Point 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 Access Point (for
example 192.168.1.10), with subnet mask the same as the Access Point (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.
Reset the Access Point to Factory Defaults
To return the Access Point to the factory defaults power off the unit, press and hold the Reset
button, and power on the unit again. Continue holding the Reset button for 15 seconds and
release. Cycle power again and the Access Point will have the factory default conditions.
Note that the default IP address will only become available after the Access Point spends 2 to 3
minutes searching for an address from a DHCP server.
