Hi Larry, Thanks for the info. I tried setting the channel to one that is listed in the link you provided, and even to one that is listed in phy info. ch=36 is nice and safe. however when I type: > iw dev wlan0 info It is still reporting it's on the old channel (11). Any ideas why it is reporting the old channel? Thx.

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.
