And, if the pc u use is using DHCP to get IP address from router, u'd better find a way to make the ip address of the PC fixed.
1. configure the ip address manully by setting up: ipaddress, net mask, DNS server(the router ipaddress).
2. some router support to bind ipaddress with MAC address. So, find out MAC of ur net card and set it up in ur router.
Normally, the interface to configure router is http://192.168.0.1 or http://192.168.2.1. read the manual of the router first. if ur landlord didn't setup password, u r able to access the router configration.
