0.9.1.90 (on Ubuntu 11.10) fails to maintain wifi connection when multiple APs have same SSID.

[Jason Cipriani <jason cipriani gmail com>]

I'm using NetworkManager 0.9.1.90 (it came with Ubuntu 11.10). I can't establish a reliable wifi connection to a network with multiple APs using the same SSID. dmegs shows immediate deauthentication with reason 2 (authentication no longer valid), and I am repeatedly prompted for a wifi password. I've Googled around but mostly only found bug reports > 3 years old.

I'm fine on networks with one AP (I'm at work now tethering through my phone because I can't use the network here when I'm running Ubuntu :/ ).

How can I make this work? It's hindering my job significantly.

Network adapter is: Realtek Semiconductor Co., Ltd. RTL8188CE 802.11b/g/n WiFi Adapter (rev 01)

Here is syslog output (I've removed cfg80211 frequency scanning info). Note it connects to 00:18:0a:31:50:21, immediately deauthenticates, then attempts to connect to 00:18:0a:31:50:2a. This cycle repeats endlessly (trying random APs each time).
