A wireless card for laptops is used to enable the laptop to connect to a wireless network. A wireless router is used to keep track of the whereabouts of devices connected to the network. It is part of the network. This is a very basic answer but I think it should be enough to answer your question.
If the laptop computer has a wireless adapter installed, either internally or externally, and it can communicate over that adapter to the wireless router, it is time to disconnect the Ethernet cable. The computer will only use one network path to the router at a time.
Open up your network settings that you can access via which ever computer you used to set up your wireless network. This is usually the computer connected to the router which is connected to your modem. When you open the configuration you will need to change the setting that controls how many devices can be connected to your network. This is usually either a drop down or an open field where you can put in a specific number or say unlimited. There are a few other options but I believe that this will fix your problem.
WiFi ready just means you have a wireless card you need an internet connected wireless network available to access the internet.
