Not sure I completely understand your question, but I’d say you attach your wireless access point (or router if you like) directly to LAN port of iDR. Make sure it is in access point mode and DHCP range is above 192.168.1 (or was it 0).10 so there are no IP conflicts with surface, touchscreen and iDR itself. In case your FOH cable is broken you still got connection to iDR over wireless. And I definitely suggest to use 5 GHz band instead of 2.4 GHz. iPad has this range built in, but your computer might require an USB dongle.
