# La password è corretta, ma il collegamento non funziona

Se si è sicuri di aver inserito la password per le rete WiFi corretta, ma non si riesce ancora a collegarsi, provare con una delle procedure sottostanti:

- Verificare accuratamente di essere in possesso della password corretta

  Prestare attenzione alle lettere maiuscole e minuscole: le password tengono in considerazione anche questo aspetto.

- Provare la chiave di accesso esadecimale o ASCII

  The password you enter can also be represented in a different way - as a string of characters in hexadecimal (numbers 0-9 and letters a-f) called a pass key. Each password has an equivalent pass key. If you have access to the pass key as well as the password/passphrase, try typing the pass key instead. Make sure you select the correct wireless security option when asked for your password (for example, select WEP 40/128-bit Key if you're typing the 40-character pass key for a WEP-encrypted connection).

- Try turning your wireless card off and then on again

  Le schede WiFi a volte possono bloccarsi o avere dei piccoli problemi momentanei che non consentono di collegarsi alla rete: provare a spegnere e a riaccendere la scheda WiFi per ripristinarla. Per maggiori informazioni, consultare Wireless network troubleshooter.

- Check that you're using the right type of wireless security

  When prompted for your wireless security password, you can choose which type of wireless security to use. Make sure you choose the one that is used by the router or wireless base station. This should be selected by default, but sometimes it will not be for some reason. If you don't know which one it is, use trial and error to go through the different options.

- Check that your wireless card is properly supported

  Some wireless cards aren't supported very well. They show up as a wireless connection, but they can't connect to a network because their drivers lack the ability to do this. See if you can get an alternative wireless driver, or if you need to perform some extra set-up (like installing a different firmware). See Wireless network troubleshooter for more information.
