OSX and iOS Wifi defaulting to the wrong SSID

[lehmanp00]

Hi everyone,

I thought I'd ask this question here since I haven't been able to find a good solution anywhere.

About 3 years ago we implemented a 2 SSID wireless network. One is a WPA2 secured, full-bandwidth SSID and one is an un-secured throttled SSID. OSX and iOS devices are constantly defaulting to the un-secured SSID. Its a total pain. We have been using at "just remember to check your Wifi network' approach with users, but we all know how that goes. Blowing away all the saved networks and re-attaching helps for a little bit, but it seems to only keep for a few days.

Anyone else seen this? Any suggestions?

We have a policy that removes our unwanted networks from the machines, BP1 in this instance

networksetup -removepreferredwirelessnetwork en1 BP1
