I have a cable connection coming to my apartment from somewhere in the house. I assume they have a router and a modem and they do like this to grant connectivity to the whole house. To connect, I have to use a static IP address and a netmask like 255.255.255.128.
I am wondering: can I install a wireless router in my flat in order to have wifi connection? Is it enough to buy a router and connect the LAN cable that now I connect to my PC directly to its WAN port and it will propagate the signal via wireless? I assume I have to set the routers IP to the one that I use now on my computer, and the router will take care about generating local IP addresses for the computers connected to it. I would therefore use DHCP settings on all clients of the router.
Do I need to check something specific when buying the router?
Thanks for your advice
