OK, I se the ESSID and channel (obtained from iwlist eth0 scan) with
iwconfig eth0 essid "myap"
iwconfig eth0 channel 11
I notice that the output of iwconfig eth0 gives a setting for the access
eth0 AR6000 802.11g ESSID:"myap"
Mode:Managed Frequency:2.462 GHz Access Point: 00:B4:63:97:AD:27
Bit Rate=1 Mb/s Tx-Power=15 dBm Sensitivity=0/3
Link Quality:188/94 Signal level:-163 dBm Noise level:-96 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:13 Invalid misc:0 Missed beacon:13
and ifconfig eth0 gives values for received and transmitted data:
eth0 Link encap:Ethernet HWaddr 00:1F:3F:BE:45:2B
inet6 addr: f58b::263:ceff:fd87:ed25/64 Scope:Link
UP BROADCAST MULTICAST MTU:1500 Metric:1

TX packets:12080 errors:0 dropped:0 overruns:0 carrier:0
RX bytes:607951527 (579.7 MiB) TX bytes:128021 (125.0 KiB)
but if I start pinging an external IP address from the Freerunner and pull
the USB cable, pings stop returning until I plug the cable back in and
restart networking on the host.

Sorry, I meant GPS, not WIFI.

I see the same group of lines repeating:
but I'm not sure how to interpret them. Thanks for your help!
