My sister recently came back from college with her laptop & we wanted to set up her wireless router for it & for our new wii which has an internet browser. Its a D-Link Router & I installed it using directions from the manufactorers web site. Its connected to our cable modem & it took awhile to get it working & it finally did. Then one day it stopped working, the router would still send out a wireless signal but our family computer thats hooked up to the modem couldnt connect to the internet. I unplugged it, restarted everything (computer, modem, & router) but nothing seems to work. I even reset the router to the default settings & tried connecting it to the modem again bot nothing has worked. Im not a computer genus & need some help.
