Hello. Today I've been trying to set up a wireless network (at my grandma's house >_< ) . My troubles started with the printer. I couldn't get it to connect to the Uverse network for my life.

So, I logged in to the router through my browser and changed the password. Said password is not accepted when trying to connect to the network through the computer. I think I need to reset the password to the default, but I don't want to mess up the network. My grandmother's phone and tv, etc. are all connected to the Uverse network, and I have to leave today.

Will resetting the password solve my problems?  How should I do this? Will it require reconnecting any of the other devices?

Thank you,
