...Lastly, why do you ask me for my chosen ip addresses in your closing paragraph? I consider this private information and not germain to my question. Please explain why you wish to know all this data.

NASNoob, I would have asked for it if he had not. If you ask for help, you will get questions, and some of them may seem irrelevant to you. But (a) sometimes they are relevant (not always) and (b) we only have the information in your posts to go by.

-your 10.0.0.x addresses (as you ought to know) are not publicly routable, Those addresses are reserved for private use, and your devices cannot be reached over the internet using them. My pro is 10.0.0.10, my duo is 10.0.0.11, my nv+ is 10.0.0.12, my RN102 is 10.0.0.13. That information does not let you reach any of my gear, so it is totally safe for me to tell you those addresses.

-A lot of people who post here with static address issues have absolutely no idea how IPv4 addresses, gateways, and subnet masks are constructed. So confirming that the IP addressing is sensible is actually an important step. Many of them also use a mix of DHCP and static, and then lose connectivity when they replace their router, and don't why.

-The normal subnet mask for 192.168 addresses is 255.255.255.0. With that mask, all local addresses must be identical in the first 3 fields - and that includes the gateway address. So you need to be consistent about 192.168.0.x or 192.168.1.x. It is simplest to just enable dhcp, and have your brother set the address if he wants to. Personally I prefer address reservation in the router combined with dhcp. It makes things much easier esp. with my mobile devices that connect to various networks.
