Hello my dear friends of the online internet community.
Well,... I believe that i have a bad ip schema.
my setup is:
(modem)-->(dell power connect 2216)-->(comp.{7 comp's})
only one computer gets a default gateway, (the one that i did the following print screen on)
-tcp/ip settngs are set to autmatic DHCP and DNS
-pings google flawlessly
...
