The wifi list screen is small and you may have to scroll through 2 or 3 pages' worth to find what you're looking for. I've had as many as 4 wifi "pages" to scroll thru to find the one I was hunting. Per the iFly staff, iFly devices will sometimes drop connection if too many "known" networks are saved (even if only one network is active, such as when airborne) so I have to grudgingly delete networks that I know I'll be re-connecting with soon.
