There's your problem. Two interfaces having exactly same IP range - now which interface should the kernel use to reach the iPad?

Configure the wlan interface and the iPad to one ip range, and the fixed interface to a different range.
Or I suppose you can use the ifmetric debian package and assign priority 0 (highest) to one interface, and priority 1 (lower) to another. The kernel should route accordingly.
