ok.how am i suppose to set that wireless router as an access point..? and as well the other one put it as client.?
By default routers are setup as access points.
To setup you first need to plug the computer in to one of the LAN ports on the router (NOT THE WAN Port). Then you can access the setup, via a web UI. The hardest part is knowing what the ip address is of your router. Hopefully it came with documentation telling you this stuff.
Most of the time there are at
http://192.168.1.1
or
http://192.168.0.1
Then you will need to log in, again look in the documentation for the user name a password, usually it has something to do with admin
Then should be setting on the WiFi you can give it a name and setup the security.
Personally I wouldn't use 2 routers, I would use 1 router as the access point with one of the computer plugged in to it, then buy a wireless adapter for the other computer.
Something like this would do the trick
