802.11n: How can I force a wireless adapter to primarily associate to a 5Ghz radio and not to the 2.4Ghz one?
I am playing with a Cisco 1142 AP. I have same SSID configured on both dot0 and dot1 interfaces. I have a test laptop and it has a Linksys dual-band wireless adapter. However the card always try to associate on the 2.4GHz. It will only associate with the 5GHz radio when I shut down the dot 0 interface. The laptop is running Windows XP SP3 and I'm using the windows wireless Zero configuration to configure the wireless. The following is the AP's configuration:
dot11 ssid Guest-Wireless authentication open guest-mode
interface Dot11Radio0 no ip address no ip route-cache ! ssid Guest-Wireless ! antenna gain 0 channel 2412 station-role root bridge-group 1 bridge-group 1 subscriber-loop-control bridge-group 1 port-protected bridge-group 1 block-unknown-source no bridge-group 1 source-learning no bridge-group 1 unicast-flooding bridge-group 1 spanning-disabled
interface Dot11Radio1 no ip address no ip route-cache ! ssid Guest-Wireless ! antenna gain 0 dfs band 3 block channel dfs station-role root bridge-group 1 bridge-group 1 subscriber-loop-control bridge-group 1 port-protected bridge-group 1 block-unknown-source no bridge-group 1 source-learning no bridge-group 1 unicast-flooding bridge-group 1 spanning-disabled
Is it something I can control through the AP or it's the laptop/wireless adapter's own behavior so I either need a new card or update it with a new firmware?

Thanks for quick reply! My laptop is just next to the AP. There is nothing but air between the laptop and the AP.
I actually did speed tests on both 2.4 and 5 (with 2.4 disabled of course) and I got pretty much the same result: 46Mbps MAX. I don't know if it's the linksys n card is limiting the capacity of the AP. But for now I just want it to jump on 5GHz instead of 2.4GHz...
