Why is my Guest Wi-Fi not available throughout my house?

I have U-verse internet -- using an Arris NVG599 modem/router -- and have five rooms in my home that are wired with CAT5 cabling that connect to a switch attached to the router. All of this is in the basement of a three-story home, and I use Airport Express -- on the main and top floors -- to extend the wireless signal. (Old house, mix of plaster and drywall walls.)

I turned on the Guest Wi-Fi last week, providing internet only access. I could see and log in to the guest wireless setup in the basement and first floor, but when I went to guest rooms on the second floor, the guest wi-fi network either doesn't show up at all or it shows up and continues to ask for the password.

I have compared the two Airport Express' -- and cannot find if there is a setting on one and not the other. I have to think, at this point, that there must be a signal problem with one of the Express' that is blocking or not connecting to the Guest Wi-Fi network. Any ideas/help/solutions would be much appreciated.
 
Solution
If you can see it in the 1st floor, then the network is there. If it can't reach all the way up to the 2nd floor, it's a weak signal or something is interfering with it. Maybe a access point is needed
