Title:
NetworkManager prefers slower 11b connection to 11a connection
Status in NetworkManager:
Fix Released
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.
