My laptop has recently started disconnecting from the wifi router every minute or two. When it doesn't disconnect, it still loses a bar and whatever pages I'm on while give me an error saying 'DNS connectivity changed' or something along those lines--next time it shows it I'll edit this and give the exact error. I googled the problem and figured out how to diagnose the router connection and it gave me the message in the title. I did the instructions on flushing the DNS cache, but it's still happening. I'm on a Toshiba Satellite that's about 3 years old. Is this a problem with my router or my computer, and, either way, can someone help me fix it? Please explain everything in really dumbed-down terms, because I am not tech savvy. Thanks.
