One of your laptop CAN NOT FIND your network meanwhile the other can find your network. That means your router is OK. The problem will be at your laptop.
1. Check again if you have turned on Wireless Lan? Check the switch on your laptop to be sure that it is set on. If it is off, set it on and try again.
2. Install the driver for you wireless card/chip again. And test if it can FIND your network. If it can find, then ok. If not, bring your laptop to your friend or your neighbor who owns a wireless network too. Check if it can find the network. If it can find your friend/neighbor's network, then I really don't know where the problem is. If it can not find your friend's network, then the wireless lan of your laptop is defect, bring it to guarantee.
