Did you set the correct time/day?

 

[Dozer]

yes. and he set automaticly the time over internet.
firewall is off. same hdd on other macbook is all ok

 

[Dozer]

IP4 is configured DHCP, just i toke a look and the ip and mask is a random, after click renew DCHP lease it got the "right" ip and mask. but all still the same no internet in any explorer, nothing in dropbox

Connect wifi antennas from another case.

 

[Dozer]

oh, good idea. that is working proper good. so i guess a bad wifi antena conector. I will try to solder the antenna directly to the wifi card

Probably end pipe screw fucked the antenna cable.
I never put back that screw again; passed to me one time...
