Suddenly, I try to reconfigure my network (router) and voila it works!!!

@abang could you please tell us in more details what exactly you did? So it may help others.

It looks more like a MAC address issue or something. I faced similar issues and wiping arp cache, rebooting routers and accesspoints seem to help in a lot of cases. I’m not exactly sure why this occurs. I still need to make a Wireshark trace.
