Choose a strong administrator password
Most routers require an administrator password to access the setup and configuration settings. However, the default passwords for these routers are generally weak, and some have none at all.
You should change the default password to something strong; for ideas on creating a good password, see Passwords and passphrases. Once you have set up your wireless network, you will probably not need to use this password frequently, so you can use a very strong password without worrying about the difficulty of typing it in. If you do lose the password, you will have to reset the router to factory settings and set up your network again. You may wish to consider passphrase vaulting to store these passwords.
Some routers will also let you change the administrator name; this is another good way to protect the security of your WLAN.
