Can Airport Express connect to another wifi and boost signal?

Hello,

I currently live in a building where the router is in another person's unit and we have to share it (Landlord's rules). I have spotty connection upstairs in my unit and was hoping I can use the Airport Express to connect to the original router that's connected to the cable and then extend the range that way, is that something possible or am I misunderstanding how everything works?

There is no access to Ethernet ports in my unit at all.

This is my unit:
Apple AirPort Express Base Station (MC414LL/A)

Thanks in advance for any help?

Sure, you can do that. Simply configure it to extend and enter the same WiFi SSID and password as the main unit. You might consider getting a device with better specs though. The Express is only 802.11n and configuring a wireless extender will at least halve your available bandwidth.

I'm thinking of doing the opposite:
I'm thinking of getting an used airport extreme 2011 ($25 bucks) to run wired ethernet for that 1) apple TV (I'm not getting), 2)mac mini and 3)existing airport 2009 that runs music and wifi to 3 devises. My question can i still use dropbox to mini and iPad-mini to MBAir with 2 airport wifi bases?

i think i can, i think i can

They are all on the same network, so yes, it should work.

This sadly doesn't work for some reason. I guess the two routers are incompatible.

Without knowing the specifics, it could be something on the other router that must be enabled to allow it to extend to other APs. I recall one of my former WAPs did that, but it is uncommon these days.
