hey guys, so I have a Cisco DPC3825 and a Linksys WRT160N (flashed with dd-wrt). The Cisco router has a built in modem. I have the Linksys hooked up via Cat5 and is placed where wi-fi has a weak signal. What I did was both Routers have the same SSID, but both of them have 2 different Router IPs. Cisco-192.168.1.1 and Linksys - 192.168.1.2
I turned off DHCP on the Linksys and put it on AP mode. I have no clue how to test if the second router is doing its job or not, I can't really tell and the Cisco router is fine connecting with 192.168.1.1 . So what I did was put my phone on static IP and forced it to connect to the linksys by having the router IP set as "192.168.1.2" don't get me wrong, I am fully aware the difference between Router IP and IP Adress. But I did not get internet connection :( Can someone tell me what I am doing wrong, or if I could somehow make my setup better because I have a pretty big house and need the extra boost in range. Thanks guys.

This should work fine.

The Linksys address needs to be made a static address in the Cisco (and not in the DHCP range allowed by the Cisco, so start the DHCP address range at 1.3 and up). They should also be using different radio channels (best if two of the three non-overlapping channels are used).

All devices should be allowed to either automatically get an address or use the router address -- the 1.2 address is only used to make the AP connection to the router. Everything that goes through the AP will automatically go to the router for disposition.

You can check in the router to see that the AP shows up, or you can view the full network map in the network control panel on a Windows computer to see that the AP shows up -- and...

Be sure that you connect your Linksys router to your Cisco using one of the 4 LAN ports and not the WAN port. When the Linksys is in AP mode the WAN port does nothing and no traffic will pass through it.

hey guys, i went downstairs where the second router is and i was only getting 1 bar of signal on my phone and apple tv. Do i need to put the devices in static IP so that it tries to grab the signal from the 2nd router instead of the 1st ? Also, on my linksys i have the option for repeater mode, would that help me by any chance ? thanks

edit: guys im in a bit of a funk. I accidentally set my Linksys router's IP Router address as the same as my Cisco's router ip address so i can't even access my linksys router settings via 192.168.1.2 :( how can i revert it back without having to reset the device? because its inside my ceiling downstairs.

It is easy to fix your problem. Disconnect the router used as an AP from the network and just attach it to a single computer and access it at 192.168.1.2 -- you should be able to connect to the Linksys by using the Ethernet cable that runs to it -- just attach that cable to a computer LAN port instead of to the router LAN to do that.

I suggest that you write down everything that you need to change and do it in order with the IP address change last, as that will boot you off and make you log in at that new address -- then just reattach the cable to the router and configure the router address reservation to be that same address that you use in the AP. Also, while in the AP take note of its MAC address, usually on one of the first pages, as you need to enter that in the Cisco with the IP address of the AP.
