Ok, now you need a way to connect the Router to the Landlord's Hughes Net Modem. If there is only 1 connection on the modem, you will have to plug the router into it, then plug the Landlord's computer and your computer both into the router. If the modem has more than one network connection on it (is it a 4 port?), then you can simply plug another CAT5 cable coming from your appartment into that modem. If the modem OR the router has wireless capabilities, you MIGHT be able to add a wireless card to your computer and receive a signal downstairs, but chances of that are slim because of the distance. Best figure on running CAT5 down to your appartment and to your computer.
Now, you need to find the address of the Hughes Net modem. If you look at the settings on the Landlord's computer, you can probably figure out that address. But, you may need to contact Hughes Net to find out the settings.
The router settings will depend on WHICH router you've purchased. But, basically, you set the router to use the Hughes Net modem as the gateway. If the Hughes Net modem is also acting as the DNS server (gives out the IP addresses), then the router can be set as a bridge (switch) allowing the Hughes Net modem to do all of the work. Again, that depends on the modem itself and how smart/dumb it is.
Without having specific make/model numbers of the modem and the router, that's about all the information we can provide. We can't give you specific instructions without knowing what you've got to work with.
