Make sure that the wireless function on your laptop is enabled. (Check the User Manual on the how-to)
Other than that you have to configure your router correctly. Since I am not familar with this router, I cannot guide you any more than stating that there is a particular setting on your router under Wireless Setting to turn on/off the wireless radio function. Ensure that this is turned on and the front panel WLAN LED is flashing.
Go through the router manual and configure your modem correctly including the security settings.
If the wireless station is visible on your laptop, you can add it to the list in "Manage wireless netwoks". See the screenshots in the post No network shown in managed networks
