In IE go to
tools and click on
Internet Options. A window should pop up. Click on the
Connections tab and on the bottom of the window should be a
Lan Settings button, click that. Make sure there is a check next to
Automatically Detect Settings.
The next thing to check is your TCP/IP settings. So head over to your control panel. Open up
Network Connections. Since we are dealing with your wireless signal,
right click on your
Wireless Connection icon and select
Properties. In "this connection uses the following items:" scroll down to
Internet Protocol (TCP/IP) and single click on it. Make sure its checked! Now select
Properties.
There are 4 radio buttons. The ones you want to make sure that are on are: "Obtain an IP address automatically" and "Obtain DNS server automatically"
Click OK then OK again. Hope this helps! :]
