Create password -router security

Question

Model BEFW11S4 wireless router, set up by my daughter a couple years ago, with no password. I've read that access passwords are wise for security, and to prevent your neighbors from using your connection. I have ZoneAlarm firewall and AVG antivirus, but apparently my router should also require a password for extra security?
The router was set up on a Windows 98 computer, and replacement XP has been connected for a year w/no problems. I tried the web utility, but it didn't accept 191.168.1.1 password. The window to enter password wasn't the "XP" window, so maybe using a different computer than used for original setup is the problem?
Also saw "firmware upgrades" mentioned, and don't know what this is about. Any advice regarding need for password, proper security settings, and how to do them would be greatly appreciated. Thanks for your time.

Answer 1

for changing any settings on the router , follow these steps :
1)connect the computer to the router
2)open IE and go to http://192.168.1.1 . on the login screen...keep the username blank and the default password is "admin"....if it does not accept this , it means the router password was changed sometime....
3)if u do not remember the password , reset the router for 30 seconds and do a power cycle...try "admin" in the password again...
4)get to the router ui...go to the "wireless" tab and click on "wireless security" subtab....u can set up a security mode from here...
5)for changing the router login password , go to the "administration" tab and change it..
6)if u have a different kinda screen from what i am talking about....u will frind the wireless security settings on the set up page itself....and for changing the router password , click on the "password" tab and change it....
