Force AP Selection

I am trying to use wireless internet at a motel where I am staying.  However most anything I need to do is problematic.  I have run pings to google.com yahoo.com etc, and get frequent request timeouts.  I have further tried running continuous pings on the default gateway, and have frequent packet drops.  So I have taken my laptop throughout the motel and have found that there are three APs on my floor, appropriately assigned to channel 1, 6, and 11.  When my computer roams to either of the AP's on channels 1 or 6, I have no lost packets, but whenever I go back to 11, I start loosing packets.  From my room, my laptop always chooses the AP on channel 11.  Is there any way to disable channel 11, or forcibly choose a specific AP.

I suspect this is possibly dependant on my wireless card and software.  I have a Dell Latitude XPS M1530 with a Dell Wirless 1505 802.11n Draft WNIC.  The motel seems to be using 802.11b/g APs, and based on their MAC Addresses are registered to Colubris Networks, which I believe has been bought by HP Procurve.

Any help is greatly appreciated.

In the adanced proprties of your WIFI card in the Device Manager, there is usually a setting for Roaming Aggressiveness, but I dont thin k this is what we need here. Might be able to enable it and see if it jumps to the other AP.....

yes, I have been able to tweak that, and if I make the roaming less agressive, shutoff my card and go down the hall, then when I turn it on, it selects a different AP, and I can go to my room with that, but it eventually roams off of that again, and if there was a way to disable channel 11, or force the selection, that would be much better.

Further research shows that roaming is a function first initiated by the wireless client, and then approved or denied by the AP.  Configuration would have to be performed in the wireless software and there are no options to disable a channel or force AP selection in the client software.
