I also have a problem with losing my wifi connection due to the fact that i have to physically leave my mix position in a balcony to walk outside into our lobby, down the stairs and back inside to mix the downstairs area. During this journey I ALWAYS loose my connection and thus have a fun time...
This thing is starting to drive me nuts! It takes no less than 10 minutes to synch. Also It has been having problems with losing connection to the router and has a tough time reconnecting without a hard reset of the software. Help!
