1) Setting up the router

Router WAN will not be connected to any modem, *** NOTHING ON ROUTER WAN PORT (NO INTERNET VIA PPPoE DSL , STATIC OR DYNAMIC IPs) but it will made to act as Access Point for "sharing" the shared internet connection on Desktop/PC/NOTEBOOK/LAPTOP.

First, one needs to access the wireless Wifi router's configuration settings, usually one need to connect the Wifi router, and then access its setup page either over WiFi network, or by plugging it to desktop or laptop in 1 of its 4 LAN ports. setup page is accessible by entering the router's IP address 192.168.1.1 on IE address bar or some other browser like Firefox etc. however consider your router's manual to see how to get to the settings. Ideally, resetting the wireless Wifi router and then following its setup guide would best way start off.

Once on Wireless Wifi router's settings do the following:

a)	Enable the Wifi connection. It should be enabled by default, but some routers require you to manually enable it.

b)	Secure your network. Under security options, there should be a way for you to specify a password for your new wireless network. Here you will have multiple options, probably WEP, WPA and WPA2. Set up either WEP or WPA/WPA2 security. WPA2 would be best if your router supports it. Consider having a look at the router's manual for that.

c)	Disable DHCP. Look for a setting that says something about automatic addressing (or "DHCP"). Which is enabled by default, disable it – ****this is most important!

d)	Connect the router to Computer Desktop/PC/NOTEBOOK/LAPTOP. The LAN port of Desktop should be connected to 1 out of router's 4 LAN ports via RJ45 cable. Wireless Wifi router will have one WAN internet Modem port at the back designated only for modems, as mentioned above do not use connect anything to this port so-called WAN port.

Once above steps are done Wireless Wifi router is all set.
