Hello Sorry if this has been posted elsewhere... I did have a good look around. I'm running MacBook Pro w/ retina display, BT infinity 2 with homehub 4, wireless speakers, apple tv and a WD nas drive. Every once and a while, the macbook will 'drop' it's connection to the NAS drive, the internet will stop, connection to the wifi speakers will go down. However, the WiFi signal says it's still strong. The only test I've been able to think of myself is to check the 'speedtest' app on my iPhone whilst this is happening... the iPhone works fine. This leads me to think it's the macbook rather than homehub. I appreciate this could be a few things... does anyone have any 'diagnostic tools' of sorts that will help me work out what it is? At the moment I have to restart the macbook which always seems to resolve the problem Thanks!!
