I just got an N810, it seems like it is going to be a good friend. But without WIFI to install apps I download to a PC, use a file manager to move the app to the 810's memory card. On the 810/application manager install from file. Here it fails; the tablet insists on scanning for a WIFI service to search for D/L. IT is already DIABLO 5.2008.43etc. It must be a simple tweak but I'm without a clue. Please a clear step-by-step.
