Connected to Wireless Router but not able to connect to the net

Sarithi,

Note that if you are changing the connection to modem between a computer and a router, you need to do a complete reset of the network every time you make the change. To do this, shut everything off. Wait about 5 minutes. Turn on the modem first, and wait another 5 minutes. Then turn on the device that is connected directly to the modem (either the router or the computer), then turn on any other computers that will connect through the router.

Before anyone ask, my config is

Inspiron 6000
Dell Wireless Router 2350

Try reseting the router to facotry defaults.

Hmm.. the same problem again. Today morning it was working fine. But after 3 or 4 hours of inactivity,
now back to the same problem. Again, the my wireless router is acting up. My system recognizes the
Wireless router. But I am not able to connect through the Wireless Router either wirelessly or using the
Ethernet cable!

I will post after trying the steps suggested by Steve. But why is it happening? Why my router is acting up?

My router has a time out feature. check to see if your does and if it is on try to disable it. My router is not your brand tho.
