Why wont my belkin nn wireless work?

Hello,
i have had the same router for a little while, and it seemed to work fine, but last night while i was on my mobile devise, i saw that there was no internet connection. i went to look at the router and everything else was fine except for the wireless connection, so turned the power off waited ten seconds, like i had done in the past when it had stopped working, then turned it back on. when it turned on again it had the same results, everything except the wireless and i do not know what to do. if anyone could help, i would be greatful
