ARP only, no ICMP packets?

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
? (192.168.151.122) at f4:6d:04:78:70:62 on re0 permanent [ethernet]
? (192.168.0.122) at f4:6d:04:78:70:62 on re0 permanent [ethernet]
? (192.168.151.101) at 00:01:02:c2:a1:a8 on re0 expires in 339 seconds
[ethernet]
# tcpdump -flnt -i re0 | grep 192.168.0.50
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on re0, link-type EN10MB (Ethernet), capture size 65535 bytes
ARP, Request who-has 192.168.0.50 tell 192.168.0.122, length 28
I've tried this in a number of ways, all with the same results:
Both boxes connected to network switch
Boxes connected directly using crossover cable
Both boxes to switch, default (only) ip addr on fbsd box set to
192.168.0.122/24
I've reset the wap a number of times.
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?
