Ive setup a wireless router in the basement and had no connectivity issues. However, the app is extremely limited. You can only chose from the factory preset cycles. There is no way to customize anything (e.g. heavy duty, with cold water instead of hot). What is worse is that if you dont start the machine with the app, you cannot connect to it, no info on status (e.g. How long to finish) or anything. Im hoping Samsung will provide more options, until then it is pretty useless.
