There should be an FCCID number on the serial number tag. If that's
missing, take a photograph and post it on your web pile. I'm sure it
can be recognized by someone with experience.

Common problem. Lots of options.
Since this is a new installation, you may wanna reset the access point
to defaults with the reset pushbutton.
Does it have the MAC address printed on it somewhere? If so, and you
have some Windoze mutation, run:
arp -s 192.168.1.1 xx-xx-xx-xx-xx-xx
where xx-xx-xx-xx-xx is the MAC address.
Some wireless bridges (i.e. Cisco) are setup to get their IP address
from an initial ping. Turn the power to the device off. Do the above
arp command and run:
ping -t 192.168.1.1
Now, turn on the power. Wait until the light show stabilizes and then
try the IP address.
There are wireless devices that do NOT have a built in web server.
They are configured with telnet or SNMP. This could get messy without
a positive identification.
Some access points get their IP address via DHCP. If you have a DHCP
server on your network, you might find that the access point was
assigned an IP address.
If you suspect that the access point already has an IP address, then
use nmap to scan for used addresses. Note that you'll probably need
to change the netmask to 255.255.0.0 on your computah in order to scan
different class c networks.

Host 192.168.1.255 seems to be a subnet broadcast address (returned 1
extra pings).

You can also sniff the wireless broadcasts with Netstumbler to extract
the wireless MAC address, and then use the same "arp" trick on the
wireless port to assign an IP address as previously described.
You could also just try all the common IP addresses in use. I
suggest:
192.168.0.1 (Dlink)
192.168.0.5 (Ugate 3200)
192.168.0.50 (Dlink DWL900)
192.168.0.254 (SMC2526W AP, Eumitcom)
192.168.1.1 (Netgear etc)
192.168.1.2 (Some Proxim)
192.168.1.20 (SMC 2755)
192.168.1.201 (USR 5430)
192.168.1.240 (Ovislink-AP mode, Linksys WRE54G)
192.168.1.241 (Ovislink-Bridge mode)
192.168.1.245 (Linksys WAP54G)
192.168.1.246 (Linksys WAP55AG)
192.168.1.251 (Linksys WAP11 v2.8)
192.168.1.254 (Linksys WRT54G v1.1)
192.168.2.1 (Belkin, SMC)
192.168.2.254 (Belkin)
192.168.123.254 (USR 8054, Asante)
192.168.254.254 (Cayman, Siemens)
The above list is from my failing memory and some Googling around.
Any semblence of sanity is strictly coincidental. There are probably
more default IP's in use.
Personally, methinks that posting a photo (to a web pile, not the
whole newsgroup) will be less work.
