Welcome to the group, Dave :)
I was sleepy when I posting this - the last line had a typo:

You can use iwconfig without any parameters to view your current
wireless settings:
$ sudo iwconfig
eth0 IEEE 802.11b ESSID:"ssidNameHere"
...
... Encryption key:HEX:CODE:HERE...
...and ifconfig to display your current network address:
$ sudo ifconfig
eth0 Link encap:Ethernet HWaddr 00:E0:63:50:49:AD
inet addr:192.168.1.129
....
And of course 'man iwconfig' displays more comprehensive information
about the use of this command.
