35 were unencrypted (no WEP), 18 used WEP 20 used the default network name (and perhaps the default password) Survey results (Channels 1 through 11)
Channel 6 — 33 APs (this the the default channel) Channel 1 — 5 APs (good selection, does not overlap with 6) Channel 11 — 3 APs (good selection, does not over lap with 6) Other Channels — 12 APs (channels 2, 3, 4, 5, 7, 8, 9, 10, all overlap with 6)
Tech Talk did not associate with (connect to) any network We did not attempt to log into any access point Conclusion: Not enough attention given to security
