I’ve entered the correct password, but I still can’t connect

Double-check that you have the correct password

Passwords are case-sensitive (it matters whether they have capital or lower-case letters), so check that you didn’t get the case of one of the letters wrong.

Try the hex or ASCII pass key

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

Sometimes wireless cards get stuck or experience a minor problem that means they won’t connect. Try turning the card off and then on again to reset it — see 無線網路故障排除 for more information.

Check that you’re using the correct 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.

確認您的無線網卡有被支援

某些網卡對 Linux 的支援度較差。縱使系統顯示為「無線網路已連接」依舊無法正常地連接網路，這是由於驅動程式發生問題。試著找看看有沒有替代的無線網卡驅動程式，或是對網卡進行額外設定（像是安裝不同的韌體）。參閱無線網路故障排除以了解更多資訊。
