Cannot find Network El Capitan
Hi,
I have a MacBook Pro and running El Capitan and I cannot see or find a network here at home. It is a wireless Synology DS213 drive which I want to transfer files to and from and it connects fine to my flatmates MacBook Air but I cannot see it in my airport nor in the finder sidebar... I found advice telling me to change airport channels but airport utility on El Capitan gives zero possibility of altering anything.. Please help. Thank you...
MacBook Pro (15-inch Early 2011), OS X El Capitan (10.11.3)
