Can my wireless router get an ip from another wireless router?

there are two answers to this.

1. connect a cable between the ethernet port of router one to the WAN port of router 2, but that will not allow you to also give IPs to any computer connected to router 2 from router 1 DHCP service. If you want all computers connected to both routers to get thier IPs from router #1 then you connect a cable from router 1 ethernet port to router 2 ethernet port and disable the DHCP server on router 2.
2. to do this wirelessly your router must beable to be placed in AP mode or repeater mode. Some can do this, but most dont.

You probably can't. Very few consumer priced routers can be DHCP clients on their LAN side. Simply assign it a fixed address in the right range. There's no benefit in DHCP for routers anyway (there's almost no benefit for home networks at all in fact....).
