Wireless light is green but i don't receive any...

Hi,
I have connected actiontec wireless router to zyxel cable modem.power,wan,internt,ethernet and wireless lights are green on the actiontec wireless router but I don't get any wireless signals on my laptop.Laptop's wireless adapter is working fine as it catches other neighbourhood wireless signals.Moreover, I have checked with another laptop that actiontec wireless router doesnt appear to generate any wireless signals at all.If I connect laptop through ethernet to the modem, itnernet works fine.One more thing,Wireless router and modem still connected,if I connect laptop to wirelss router (same configuration which is used to set up wireless router first time), I can browse the internet on my laptop.

Please suggest me what to do?
