Raspberry Pi network dies

Former Member

Hi,

 

I have a raspberry Pi2 but at least once a day the network dies.

 

The last thing is normally a NTP run and I have uninstalled it and reinstalled but still the same thing happens.

 

The PI is set to get a IP address but on the router has a dedicated IP address.

    Are you using wireless?  Have you checked out the syslog?
