Network problem- Software or Hardware ? i'm Lost
The set-up
I had a small home network with Mac OS X Server for many year, without big problems.
Recently, I replace my server from a MacPro to a New Mac-Mini
My Airport with a new AC Time Capsule
and my ISP from a Cable to a DSL.
Way too many changes at the same time.
Mac Mini is connected to the airport with EthernetCable.
The problem
It seems like the Mac-mini goes off-line every few minutes, for 1-3 minutes then come back.
The rest of the network is ok. With the Mini out, I lose the DNS, so I change my configuration on my MBA and everything is ok on this side.
So the problem, is either with ethernet port on the Airport, on the mini or maybe some sort of software Problem.
The problem is not always there but it is coming back more frequently every day.
Is there a tool I could use to help me locate the problems ?
Thank you
