I'm sure there are alternative methods offered above that might not need the mobile router but as I have a couple of them and the remote control is stable and quick I'm a happy bunny. 192.168.1.xxx and it works straight out of the box :) I set the MR-3040 router as an access point, connected the laptop and tablet to the Access Point network and Teamviewer 10 sees the proper IP addresses allocated by the AP i.e. The TP-link MR-3040 is also an Access Point (the lightbulb moment lol) which isn't affected by the custom firmware. This programme allows me to control the DSLR from an Android tablet wirelessly. I have a TP-Link MR-3040, which is a battery/usb powered mobile router, which has been flashed for using with an Android programme called DSLRController.
Nail it and it is so comment about using a mobile router was the clue I needed
