Any ideas as to how I can set wlan0 to the channels in Band2?
There is no channel 19 in wifi! That is the reason you cannot select it.
To select Band 2, you would need a dual-band Access Point. Do you have one?
Clearly, you have little knowledge of wifi. I suggest you read
http://en.wikipedia.org/wiki/List_of_WLAN_channels.
