| Just bought RT-N56U and have problems connecting it to the existing network. I have a linux server, managing internet connection and DHCP. I need Asus to broadcast wireless signal and be able to use its LAN ports to connect other devices. The problem is whatever I do Asus does not see internet connection.
1. I am assuming I should be using AP mode, not router.
2. I am connecting LAN cable (from my server via switch) to LAN (not WAN) port.
3. I have changed default (LAN IP) 192.168.1.1 to .55 since my server uses .1.
What am I missing / doing wrong? How to make Asus see internet connection?

If you already have a Linux server handling the connections, just use AP mode. Interconnect the router using a LAN port on the router (as you've done). The router doesn't need to see an internet connection unless you want to have it serve as the DHCP host.

| Thanks for clarifying, Tom!
Do you think it would be a good solution to assign a fixed IP to Asus (out of my server's DHCP pool) and enter it as "LAN IP" in Asus configuration?

| It's not a bad idea to use a fix IP since it makes accessing your AP easier when you know the IP. There is just one more thing. Since AP means basically Bridging from WLAN to LAN, you won't need NAT, so deactivate that along with DHCP. And since your Server ought to be protected by a firewall I strongly recommend to disable the one on the Asus device (if it doesn't happen automatically upon AP mode).

I have had the best success with the following:
1. Reserve an IP address on your DHCP server for the router. No lease expiration.
2. On the router, manually assign the reserved IP address from your DHCP server. On my AP, I set it with "Get IP Automatically" turned off, "IP Address" set to the reserved address, "Subnet Mask" set as needed (usually 255.255.255.0), and "Default Gateway" set to the IP address of the DHCP server / WAN gateway.
Prior to turning off "Get IP Automatically", I experienced periodic pauses in wifi access through the AP. Setting it manually on the AP got rid of any pauses.
So the short answer would be yes, unless you run into any issues. Either way, you'll definitely want to assign a fixed IP to the Asus in the DHCP pool.
As Remo suggested, you should turn off the firewall options on the AP.

| Remo, Tom, thanks both for your good advices. I have my Asus in AP mode (this automatically disables most of the network functions like DHCP or firewall) and with fixed IP assigned. Works flawlessly.
Now all is left is to finetune WiFi settings so all my 802.11g and n devices work faster (for now it is not more than around 40 mbps and I was hoping to get closed to 100 - this is basically what I have when connecting via LAN).
