|I assume that your wireless router and wireless card can reach across the room, house, etc. I assume you shut down the computer properly before moving it. That leaves:|
Wireless routers can be fickle. Try unplugging it, wait a few seconds and plug it in again and see if that works. If not then restart the computer and see if that works. If not, look on the bottom right of your screen for the icon that when you hover over it shows 'wireless network' or something similar. Double click on this, look for the correct wireless connection (If you have near neighbors, you may show some that are not yours, presumably you will not have the password to access them. If you cannot identify yours, call the person who set up the router for the name.), hi-lite this and click the 'connect' button on the bottom [You could actually try this first, but I find wireless routers often need rebooting, especially inexpensive ones].
You have to be a little bit crazy to keep you from going insane.
