Does it work if you connect the router and laptop with a cable?

  generous88 22:49 24 Aug 08

yes it works

Are you using the latest wireless drivers for your hardware? Are you using the built-in wireless management software or a third party version? What version of Windows?

  generous88 23:39 24 Aug 08

its the latest drievers...and the windows is XP SP2

and it's a built-in wireless

OK - are you using Windows to manage the wireless card or the software that came with the laptop? Have you tried temporarily disabling the security on the router to see if you can get the laptop to connect?

sorry didnt get you..but i'm not able even to access to the router..when i type the default gateway in the explorer as i used to, to access the doesn't access

You mean accessing the router config while using a wireless connection? You access the config with a wired connection - and you just said that works. Unplug the cable to test the wireless when you've made changes.

ok got,firewall, and NAT are all enabled...shall i disable something ?

Disable wireless encryption - probably under Security. Leave NAT and firewall as they are. Disconnect the cable. Can you connect successfully wirelessly after that?
