I got a new router and set it up and it worked for months. I got on my computer today and i could not access the internet. my router showed that i had a wifi connection but none of my devices ( Kindle, Wii, Laptop) could access it. I unplugged the router and the internet on my desktop computer started working again. I played around with various things, such as the proxy server, to no avail. im no computer wiz and i have no idea what else to do.. Any ideas??
