Background: is a wi-fi router ASUS RT-G32 to it via the WAN connects twisted pair to the LAN hostels and Internet, but this connection is only available internal network between our two laptops and a global network.
When connected via LAN, respectively, an external LAN, but without Internet.
The problem: in fact, the subject, of course, with the Internet. Once tried to set it so happened that through the LAN port were all available, but often flew the Union, and for a few hours and does no longer connect, I had to send back.
PS: the firmware changed the IP and DNS router gets a gun, in a system using a wireless connection it is also worth automatic options.
Bonus: it's less important, almost invisible problem is the p2p connection, made via port forwarding, but nothing comes out, it is quite possible that they are by default disabled University administrators(as well as disabled access to online games).
I really hope for your help!
