Installed ubuntu server and openssh on old laptop installation went well. Settings good, all firewalls down, ssh active BUT still no machine can ping server n server can ping machines. Tried pinging ip4 with phones and tabs same result. Pings and ssh verbose usually timeout.
On running traceroute to devices no results just empty rows. All machines on same subnet and DNS.
Laptop connected to router with cable
Im out of ideas please help.
