The channel is controlled by the AP.  In Managed mode you can't set the
channel on the client.  It will automatically recognize the AP and use the
correct channel.  Perhaps the reason your card isn't associating with the
AP is that you need to set the ESSID (network name) explicitly to the value
being used by the AP, or for some cards, to "any".  I think the Orinoco
cards can do "any", but I use the explicit ESSID.  The command line would

    iwconfig eth0 essid "MyNetwork"

(substituting whatever ESSID you configured your AP to use).  It's possible
that wvlan_cs sets "any" by default, and orinoco_cs uses the default on the

Hope this helps.
