Hi Jeff,

Are you talking about getting 3G data or wifi?

If it's 3G data via the Huawei adaptor, then it should work, but it 
won't appear as wlan0, rather ppp0 when it's all setup correctly.

If it's wireless as in 802.11b/g/n wireless then you've got problems 
because you don't show any wifi adaptors installed.

For the 3g data your actual using a modem in which case your dealing 
with pppd and stuff.  When you plug the usb-modem into your pc, it 
should appear as /dev/ttyACMx or /dev/ttyUSBx depending on your kernel 
and the device drivers.

Are you running this box with a gui.  If so, install network-manager and 
select Mobile Broadband and set the device up there.  Otherwise you'll 
need wvdial or pon to setup the ppp connection.

Regards,
	Daniel.
