[Ham-Computers] Configuring a distant router connection for home QTH

[John Hensley]

Thanks to everyone for this start in learning how to do this.  I'm on digest modeso that is the delay in responding.  Several questions were asked and two methods were suggested.  
To answer the questions:
The Cox modem in the house is connected to our Linksys Wireless router via a CAT5  cable and one home computer is also plugged in.  It was that computer which set up  the Linksys. In other areas of the house, the kids are using wireless laptops, one work  station which is wireless, and a wireless printer.
A CAT5/6E cable from our existing router to the new out-building would be about 100 feet.  
Solution:  
1.  I run a CAT6E cable from the house router to the new out-building router.  2.  I leave this CAT6E cable off the new router during the set-up.3.  I plug a PC into the new router and bring up it's Linksys control panel.  4.  I set DHCP Server to manual on the remote router, and assign an IP number that is      one digit off the house router's IP number:
(e.g., Motorola Modem 192.168.0.1,         1st Linksys 192.168.1.1,  Remote Linksys 192.168.1.2, subnet 255.255.255.0)
5.  I then plug the CAT6E cable into the remote Linksys and my laptop should now see     the Internet ??
Is this basically correct?
