hi. i recently bought a laptop with vista already INSTALLED in it. i also purchased a trendnet wireless router. i currently have WPA2 PSK / TKIP encryption. the first day i got my router, i easily installed it and connected with my laptop with no problems. i did select the reconnect at logon box. however, when i restarted my computer, i quickly noticed that it didnt AUTOMATICALLY connect. so i tried to connect manually. and now it doesnt let me. ive done everything exactly the same, but after i put in my key, i get this popup "the wireless authectication settings on this computer do not match the requirements of this network" oh, and the router is installed to an xp desktop

any help is greatly appreciated.i just realized that maybe i shouldve posted it in the NETWORKING part  Did you try to reset router?yes. i have resetted the router several times   1. Click on Start button.
   2. Type Cmd in the Start Search text box.
   3. Press Ctrl-Shift-Enter keyboard shortcut to run Command Prompt as Administrator. Allow elevation request.
   4. Type netsh int ip reset in the Command Prompt shell, and then press the Enter key.
   5. Restart the computer.
thanks for the quick replies. ok i did this on my laptop and there was no improvement. was i supposed to this on the desktop?No.
Make sure, that your router, and your laptop use same authentication methods: WPA, WPA2, TKIP, or AESi think they are using the same ones, but how do i make sure on my laptop? im very new to vistaI think, Vista, by default uses 802.1X authentication type.
To check what's going on, see here: http://windowshelp.microsoft.com/Windows/en-US/Help/d4a8a69a-f885-4766-a991-446031bc32881033.mspx
Click on To enable 802.1X on a wireless network, and it'll SHOW you the way to change it to whatever you have your router set to.ya, they were using the same ones..which is?
Did you try to change it to 802.1X?You may also try here: http://support.microsoft.com/default.aspx?scid=kb;en-us;928233
