I have my modem plugged in downstairs to a D-Link DIR 868L which provides more then enough internet connection for the downstairs, but not the upstairs. I ran a 50ft. Ethernet cable upstairs and plugged it into the Ethernet port 1 on the 868L downstairs and into the WAN port on a Linksys E2000 upstairs, I am getting great speeds now upstairs, but my security cameras that are plugged into the Linksys upstairs can't be connected to through my iPhone app anymore. The camera system is a QC40196. I tried to find the solution online, but honestly my brain just gets all foggy trying to make sense of what people are talking about.. I'm hoping maybe someone can give me a step by step solution?

UHmmmm I believe the problem is you now have TWO networks instead of ONE network so your iPhone App won't work on the D-Link Network while the Camera is on the E2000 network, unless you do some major reconfiguring.

Your BEST solution to this design is instead get a Wifi Range Enhancer instead of a second router. What that would do is be a 'dumb' signal device to extend the D-Link either via the Ethernet connection or because it is close enough to the D-Link signal to just replicate it in the new 'circle' the Extender makes. Here is a simple article on it http://www.pcmag.com/article2/0,2817,2399953,00.asp
Plug it into the LAN port on the linksys and disable the DHCP and assign it a unused address in the network of the main router.

Your problem is the NAT on the second router. When you use the LAN port you are running as a AP and there is only a single network.

The first It I assume is the cameras and the second It is the cameras as well? I went into the linksys setup and disabled the DHCP server. I went into my camera system and changed the ip address to 192.168.0.140. Do i need to type in an ip address for the linksys?

Maybe I should have been more clear this is a very common question and I rushed.

You want to connect your routers LAN-LAN. This makes the linksys router into a AP in effect. You need to change the linksys ip address to something that does not conflict. The cameras need to also be assigned addresses in the range used by the main router. If they learn via DHCP then your main router will just give them IP addresses if you manually set them then you need to pick address from the main routers subnet.

The second router is acting pretty much as a dumb switch as far as your cameras are concerned.

Okay so having my upstairs router ethernet cord plugged into Wan and plugged into port 1 on the downstairs router is okay? Upstairs router has DHCP disabled. now i need to change the ip address on the upstairs router.. to do that i go to the setup page where I disabled the DHCP and I enter say 192.168.1.141 where it says ip address and save that?
 


No the key issue is to NOT use the wan port. You want to plug it into a LAN port

Wow, shows how little I know about this computer stuff :) I plugged the Ethernet cable into port 1 on both routers.
 

It actually is not really that obvious that this will work since it is directly reverse of what all the manuals tell you to do. It is sorta a hack that just happens to work on all routers mostly because they are stupid.

so now that it is hooked up this way I can't access the basic setup from the computer that is hooked up to the upstairs router in port 2. I also still can't hook up to my cameras..
 
Ok lets try a example.

You have your main router set to 192.168.100.1
You have your dhcp pool set to say 192.168.100.100-192.168.100.200

So now you change the IP on router 2 to say 192.168.100.210
Then change the cameras to 192.168.100.211,192.168.100.212 etc.....or let them be assigned via dhcp.

You should now be able to access any of the equipment from any device it is all one big network.
