So i try to change my MAC manually in properties/advanced and with macshift and my connection work.Let me get this straight you get one streetpass of one mac and then when it changes nothing happens until 8 hours after?
If so do you still have internet access when the mac changes.
One little note for everyone. DON'T use the cycler until you've tested that when changing mac's you can still connect to attwifi and have internet access. You can test that by using macshift and manually changing between macs. Try to manually change your mac and test the connection.
The cmd command netsh wlan show hostednetwork show me the 3ds just when it open not in sleep mode.
I also tried to refresh :my 3ds connection - start/stop hostednetwork - the reshared the connection.
