Because the router has a default setting which assigns it one of the 
private networks 192.168.x.0 (the value if x depends on the router type). 
The router usually gets the *.1 address. See the manual for the default 
network or set your machine to use DHCP on the interface where you want 
to setup the router.

If you have a real router it will allow you to change the network to your 
preferred range, but if you have something like the brain dead 
thing I got with my DSL you are bound to the 192.168.x.y networks.

Anyway, you should change both routers to work in the same network if they 
are supposed to talk to each other (and they should have different IP 
addresses - but you probably know that already). If you are using DHCP on 
your network already, make sure that only one DHCP server exists. Usually 
the routers have DHCP enabled by default.

Here is another trap: If both routers are configured as Access Point (that 
is the default configuration) they will not talk to each other via 
wireless. You should set one of them as client or repeater. However, 
AFAIK repeater mode can only work if you don't use WPA/WPA2 encryption. 
I.e. if you can't setup one of the routers as client, you have a more or 
less open access point - I don't know if that is what you want. Remember: 
WEP is not encryption but a joke.
