PC ip address and router ip address?

I checked my ip config through cmd line and found my ip adress is 192.168.x.x . When i set up my router the instructions told me to use the same address, which coincidentally matches mine? Are they always supposed to match?

1. the router ip will be 192.168.1.1 192.168.2.1 or 192.168.0.1 depending on your model.
Yes it will match the range 192.168.x.x because the router will issue IP addresses to your clients on the network.
MY setup is as follows.
Router IP: 192.168.1.1
2 PC: 192.168.1.105 ,192.168.1.107

to configure or access the admin interface use
http://192.168.1.1 or the ip your model router uses.

2. Your router's IP cannot share an IP with your computer. If you have DHCP enabled you will never need to worry about your IP address unless you have someone else on your LAN you want to connect to.

3. You are probably setting up a double NAT. This will work most of the time but... sometimes this can cause problems. It sounds like the modem your ISP sold (or rented) to you is a router and it probably uses the same range as the router you bought. If you wanted to you could turn off the DHCP server on the router you bought, and plug the cable coming from your modem into one of the LAN ports on the new router. This would essentially turn your pretty new router into a pretty new switch. Even if it's wireless your wireless clients will obtain their IP from the router you got from your ISP.
This may be confusing, hard to explain in one paragraph. If you need more info let me know!
