After reconfiguring my internal network to private ip addrs, I'm trying to reconfigure a DLink wireless access point. At first I tried using the old IP addrs and configuring my workstation with an alias on the old network. That didn't work, so I've reset the wap. The manual says default addr is 192.168.0.50 netmask 255.255.255.0 The box I'm trying to access it from has an ip of 192.168.151.122/24. I've added an alias to the interface for the 192.168.0 subnet: Routing tables Internet: Destination Gateway Flags Refs Use Netif Expire default 192.168.151.101 UGS 0 0 re0 127.0.0.1 link#10 UH 0 59752 lo0 192.168.0.0/24 link#1 U 0 121 re0 192.168.0.122 link#1 UHS 0 0 lo0 192.168.151.0/24 link#1 U 0 54 re0 192.168.151.122 link#1 UHS 0 0 lo0 When I attempt to access the WAP, I see only ARP requests, and it appears not to answer: $ arp -n -a ?

When it comes on, the LAN / WAN / Power lights appear to blink in a reasonable sequence, and the LAN light blinks when ever an ARP packet goes out. I have difficulty believing the wap unit is defective, as "it worked before I changed all the addresses..." Suggestions?
