Linksys Wireless Router :: Finding Password On E3000?

A retailer (Best Buy's Geek Squad) made adjustments to my Linksys E3000 router when I bought a Sony Media Player from them a number of months ago. It was the first wireless device integrated into my wired LAN network (three computers).
 
In attempting to set up a GUEST connection, I pulled up Cisco Connect which I originally used to set up my network. The BB Geek didn't use a key and followed a different procedure unknown to me.
 
As I face the Cisco Connect screen now, it tells me "Can't access your router settings. The router password has been changed." Then in the "Router password" block, it gives the original password I assigned.
 
I had written another name I thought was associated with the changes made by the BB Geek so I copied the password there now, inserted the new PW, and clicked Next. I was then asked if I wanted to proceed with the change ... but the change it was proposing was the exact PW I just copied. Confused, I cancelled the operation.
