I have COMPAQ PRESARIO F30US the wireless assistant is not workin

First check to make sure that you're wireless internet is turned on. Sometimes there is a button to push above the keyboard and others it is an FN key combination. If that does not work then go into Device Manager. Look for your wireless adapter, if there is a yellow! or a Red X, then right click on it and update driver. Finally, in Device manager right click on your wireless adapter and do a driver rollback. This will uninstall the new driver and give back your old one, if your old one was working. Repost after you tryed those three options.
