The wifi card in your computer may be bad or you somehow shut off the wifi on your computer. 

No, dear Laurelie! There is nothing in the world what lasts forever! EVERYTHING disintegrates at some time! And, unfortunately, will stop working inevitably ! But much more sadly, endless number of the technical devices are malfunctioning while they should working yet! And lot of bastards are doing the damage to you (to all of us) deliberately , on purpose ! Even those, who suppose to provide to you well functioning service! Especially when you have the cheapest possible link of the list, like I have. THEY DELIBERATELY ARE PROVIDING TO YOU SO BAD CONNECTION (TIME TO TIME IT SIMPLY UNINTERRUPTS! FOR THE SECOND ONLY -- BUT THE BAD DAMAGE IS ALREDY DONE!) IN PURPOSE TO FORCE YOU BYE MORE EXPENCIVE SERVICE, AND SECONDLY THEY DO PROVIDE THE USELESS BAD CONNECTION BEEING IN CONSPIRACY WITH BROADCASTING COMPANIES WHEN ARE SOME BIG SPORTSEVENTS OR THE OTHERS BIG EVENTS -- IN THE ORDER TO PREVENT WATCHING BY YOU THOSE EVENTS THROUGH THE INTERNET! (since you ALLEGEDLY are so poor -- you ALLEGEDLY ARE NOT PAYING FOR EXPENSIVE TV-CHANNELS)(or they know it for sure -- among the massive number of the others things about you)          Well, when you loose the connection with the internet -- you have to reboot everything in your power -- TRUinstall in the Control Panel for start and restart the functioning of your modem(the connection stick). In some cases also helps simple removing off the internet modem-stick and then putting it back. Sometimes the entire computer is so full of harmful junk programs that will help only the proper cleaning. And one more thing -- the Shockwave Flash-program is working very very badly! It also causes quite bad malfunctioning of everything! In such case redownload it from the Internet (when you can). GrigNik
