<li>ISP user name and password. If you want to connect to the internet check with your ISP to get your own User name and password, if not ignore this step.
<li>Looking at the security options, make sure:
<li>MAC address Filtering is not enable. If it is, remove all the MAC addresses on the MAC address table, and enter your Laptop's network card MAC address. With MAC Filtering On, do not forget to enter the MAC addresses of all you wireless devices on to its table.

<li><b>A Laptop to Laptop connection</b>, please make sure the wireless settings on both laptops are the same. <br />
<li><b>Inconsistent wireless Keys</b>. The key on the laptop has to match the one configured on the router. <br />
<li><b>Drivers out of date</b>, update your wireless adapter drivers or your router firmware by checking the manufacturer web site. <br />
<li><b>Wireless not enable on the router</b>. If wireless is not enable on the router, there is no Wi-Fi signal at all. some Router would have wireless turned off by default, and it is the administrator decision to use it or not. <br />
