Title:
  NetworkManager prefers slower 11b connection to 11a connection

Status in NetworkManager:
  Confirmed
Status in network-manager package in Ubuntu:
  Confirmed

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.
