I'm loving my new pi but got an annoying issue on network services.
Every x minutes (usually under 5) SSH/SFTP/Apache all seems to stop working on the network. SSH gives connection refused/SFTP gives connection timeout/Chrome gives 'Connection Unavailable'
However I can still ping the IP (192.168.1.100) throughout this time.
Then all services come back online.
Mysterious! Any ideas? I'm running the Pi/Desktop through a TP-Link switch, which is then connected by Cat6 to the router.
