Reconfigure a Network

I setup a new router, and it works great. However, the first time I connected to the internet through it, I skipped the Network Setup Wizard or whatever it's called. My idiot of a friend "helped" me setup the network without me knowing it, renamed it after himself, and put password protection on it. I want to remove the password and rename the network. I checked all the router settings to make sure that WPA or anything else was active, but the problem persists on my craptop, and the network isn't showing up in the "manage wireless networks" screen. Any suggestions?

You should be able to change the network name, PW, etc., at the router's online administrative site.
First, make sure the system has Internet access, open Control Panel/Network and Sharing Center, click on Local Area Connection/Details, and write down the router's "IPv4 Default Gateway" address.
Next, open your Internet browser, enter the IPv4 address in the address box at the top of the screen, press Enter, type your User ID and PW, and click OK.
You should now be able to make any desired changes.

Thanks for the reply! I did this, (it was actually the router's DNS address) and it was successful. I had done the changes before on a desktop running XP with an ethernet connection, but nothing happened. So I assume that, in the future, the wireless settings and profile should be managed on a computer using the wireless connection and Windows 7?

You're welcome.

You should be able to make changes from any computer on the network.
