Wow, does no one here know how to setup a modem->router ?
Okay., 1)Shut down your desktop and unplug the modem power cable.
2)Then unplug the network cable from your computer. Plug that cable into the WLAN port on the router.
3)Take another cable and plug it into the LAN port 1-4. The other end plugs back into the computer.
4)Plug the modem power back in. Plug the router power in, then power on the computer.
This should get your desktop setup.
Tro get thge laptop up.
1) On your desktop, goto 192.168.1.1 and enter the default pass/user Usually admin/admin
2)Find the wireless security and set an SSID, its the name of your network. I'd set it to be unique but annonomous to you. Set the security to WPA2 and set up apasskey. Hit save/set or applky
3)On the laptop, open the wireless connecter, btm right by the clock should have it shown, find your network. You named it above. Click it, enter the passkey.
