I bought a Belkin N300 Modem Router combo.It has 1 phone line jack and 4 LAN jack.I already had another modem from my ISP. I used to connect the LAN cable coming out of that modem to my machine directly and use internet. Now I would like to have wireless internet available in my home everywhere. How can I set this up? Everywhere it is told to insert the LAN from modem to a jack named "Internet". I couldn't find any such jack I only have modem, numbered LAN and WLAN.
In a nutshell I have done a mistake by buying modem-router combo. How may I use the router functionality alone in this device?
