Cannot connect to WiFi

I had a similar problem with my Dell. The adapter worked but the Windows software was keeping it from fully connecting. The password had been changed on the router/wifi connection but Windows would not let me input a new password (it kept trying with the old one) and so the connection failed. I was never able to resolve the problem as we were just at the campground temporarily.

I have uninstalled the adapter in device manager and then let the system find it again. This has worked for me before. Just make sure you have the drivers available before you uninstall.

DW's computer stopped connecting to the WIFI at home. I tried everything I could think of. Finally, I decided the adapter in the computer had died and bought another. I replaced it on the mother board. (Did not want to use a stick because she only has 2 USB ports.) It STILL wouldn't connect. Finally, I discovered that there is a WIFI symbol on a key on the keyboard. I hit it, and the WIFI connected. She had accidentally hit that key and disabled the WIFI.

Oh well, she now has a b/g/n adapter where she only had a b/g adapter before.

ON EDIT:

On re-reading the OP, I see that her computer can see the WIFI signals. That means this is not your problem. I am not going to delete it, however, because someone else may find it useful sometime.

However, some networks require the MAC address to be registered in the system before allowing a computer to connect. At my house, even with the password, you won't be able to connect unless I add your MAC address to my MAC address filter. This should not be a problem on your home WIFI though. It also is not a problem if you try to connect at a McDonalds or Starbucks.

Dumb question - but are you using a correct password????

Take a ride to the nearest Starbucks or McDonald's and try connecting there. If it won't connect, you can pinpoint the problem to your adapter........

The only way you can check the wireless adapter is to buy or borrow a usb stick and try it. If it works, you have the answer. You would need the stick at that point, anyway. Good luck.
