Bug Description
Binary package hint: network-manager
When there are APs advertising the same SSID on both 11a and 11b, NetworkManager picks a 11b AP to associate to when I select the SSID of the network in the toolbar dropdown menu. It should prefer the faster 11a AP.
We have a city/university network with the same ssid, and typically there are many base stations visible.
In our office there are both 11a (54 Mbps/5 GHz) and 11b (11 Mbps/2.4 GHz) connections available
(as shown by iwlist scan, if i run it many enough times - most times it only shows the current association...).
I can make it associate to a 5 GHz AP if I manually create a connection with the BSSID of a nearby 11a AP,
and select that connection via the "Connect to hidden wireless network..." menu item.
This is on Lucid installed and updated today (2010-05-27), amd64 architecture. Hardware is
ThinkPad X200s. The iwlagn identifies the wlan card thusly: "Detected Intel Wireless WiFi Link 5300AGN REV=0x24".
Basestation hardware is Cisco Aironet 1200 with dual (11b & 11a) radios.
