Sometimes the wireless connections don't hook up correctly for me. Am I doing something wrong?
I've had this problem before. In my case, the problem I had was caused by additional software (other than the operating system's wireless driver software) that gets installed by third parties (often your laptop manufacturer) and this can cause these types of problems.
Note that this is a Windows-only problem--it won't happen on Macs.
My first suggestion, if you feel comfortable uninstalling programs, is to un-install the extra wireless connection utilities. They sometimes provide pretty graphics of your wireless network but not much more. They can cause more problems than the benefits.
Of course there can be other things that cause these problems.
Maybe you are too far away from the wireless access point, which is usually your internet modem/router.
Maybe you didn't enter the correct password on the wireless connection, or set up parameters incorrectly.
Before doing too many drastic things, you can also try turning your modem/router off, wait for 10 seconds and turn it back on. Turn off the computer, and then turn it back on.
Calling your internet provider, or a local computer store, would be the next steps if your initial steps do not solve the problem.
