As of the most recent update to ATM9 the RSInfinityBooster mod was updated and now you can no longer use the Dimensional card in other dimensions, it still works in the overworld infinitely but no longer across dimensions such as nether, end ext.
When attempting to use a wireless grid in another dimension it will state the no wireless access point in range message.
Have tried connecting it in multiple ways, directly to controller, on a cable and on a connected device.
