Can any other device connect to your router and use the internet? If not, it's a router or modem problem.

Connect to the router with a computer and check the wifi security encryption. Use WPA2 with AES encryption. Some implementations of TKIP or AES+TKIP don't work with Android. (You connect to the internet, but you won't live long enough to download a small picture.)

Try connecting to an open hotspot - like McDonalds, Walmart or any other place that has an open public wifi. Does it work?

Answering those questions will localize where the problem is. You can't fix a problem with your router by doing something on your phone (and vice versa).
