|Your list looks good to me. I think you've thought of everything. I would recommend the cable you buy to use from antenna to router be outdoor grade if you can get it for a decent enough price as this will be outside for a long period of time. The stuff you want has a very hard (yet still reasonably flexible) casing and inside the casing is a special grease. It's a bit of a pain to put RJ-45's on but if you use it (again, if possible) weather will never be an issue.|
-- Do I connect the anntenna cable to one of the ports in back of the router next to where my existing computers is plugged in, this is router in metal building, and which port do I connect to on the router from the antenna at my house ?
Yes, from antenna into a LAN port on both routers. Do read my how-to guide on adding a second router.
Briefly, here's how I would set it up. I'm going to use 192.168.0.0/24 as the subnet. This woudl give you the following set of IP addresses to use: 192.168.0.1 through to 192.168.0.254 with subnet mask 255.255.255.0 This isn't absolute just a guide. Use whatever subnet is already configured on your working router that is connected to the internet.
Router 1 (connected to internet)
LAN IP: 192.168.0.1
Subnet Mask 255.255.255.0
DHCP Enabled = yes
DHCP Scope = 192.168.0.100 to 192.168.0.199
Antenna 1 (plugs into LAN port on Router 1)
LAN IP: 192.168.0.11
Default Gateway: 192.168.0.1
Antenna 2 (plugs into LAN port on router 2)
LAN IP: 192.168.0.12
LAN IP: 192.168.0.2
DHCP Enabled = no
Antenna's 1, 2 and router 2 are within the same subnet so everything should communicate properly when correctly configured.
Any client plugging into router 2 will get TCP/IP settings from the DHCP server on Router 1.
Instructions for configuring TCP/IP settings for your antenna's will be included in the box. The easiest way to set them up is to plug directly from your PC into the antenna. If the setup guide for the antenna says it's default IP address is (again, for example only) 192.168.1.50, you'll need to give your PC any address in the same subnet....something like 192.168.1.1 will do. And of course both need to have the same subnet mask. Remember to change the NIC on your PC back to DHCP or whatever you had it assigned to previously.
Now you can plug your antenna into a LAN port on the router and access it via your web browser using the IP you configured. I would set both up before installing them physically. In fact, setup both antenna's and the router and test in the comfort of your home to ensure all is working....then go install them.
Do use the highest level of encryption (WPA2) and a complex password on the point-to-point wireless shot as well as on your wireles routers. When setting up the WLAN on router two, use the exact same SSID and encryption key.
You'll notice I assigned the IP's as follows:
Router 1 = .1
Router 2 = .2
Antenna 1 = .11
Antenna 2 = .12
I do things like this so it's easier to remember. Those IP's are also outside the DHCP scope (IP's that will be assigned to clients connecting to your network) so there is no chance of duplicate IP errors.
I hope you get this all setup nice and easy and it does the job for you. I believe it will.
Oh, and be careful drilling through the walls to run the cables....make sure there are no electricaly wires or pipes in the way and do seal the hole (around the cable) with silicone.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
