The Access Point 420 fails to obtain an IP address from a DHCP server?
By default, the access point is configured to acquire an IP address configuration from a DHCP server. If the access point fails to obtain an IP address from the DHCP server, its IP address defaults to 192.168.1.1. If this address is not compatible with your network, then the access point can only be managed through a direct console connection. To manage the access point through in-band (networked) access, you should configure the access point with an IP address and subnet mask compatible with your network.
