On most Cisco devices you can connect to the console port and change the password, but you can't reveal the old password. Do you still have the console cable?
Or are you talking about at-home wifi components?
OK - another one - are you talking about the password ***** join the wifi network, or the password ***** log in and change the router settings?
I'm sorry, that was an accident. I'm happy to do a phone call.
You'll probably have to do a factory reset. Is that going to be a huge ordeal? You'll have to re-configure them
I can do a call or walk you through it. It's whatever is easier for you. Doing a factory reset isn't hard, but you'll have to re-configure them. Are you ok with that?
It's not hard - on the back of the router you'll find a small hole that's labeled reset. you have to stick something small (like an unbent paperclip) into the hole and push the button down. Then unplug (from the power) the router, and plug it back in. Keep the button pressed for the first 5 - 10 seconds.
Then when it finishes starting back, you'll find a new wifi network. I can look up what it is - but it's the factory config (as in new, out of the box) network.
BEFORE you do that - did you buy the router yourself or get it from your ISP?
Did you do the reset already?
OK - if you still have the CD, you can run a program on the CD that will help you configure - otherwise, you can do it by:
Go to: http://192.168.1.1
username is admin (lowercase)
password ***** admin (lowercase)
From there, you can name your wifi network (SSID), set your password ***** the wifi network, and also change the admin password (you should always do that also).
