Hi, I have this Asus router rt-n56u which i recently bought, when I try to set this up by connecting my internet cable to the wan port of the router and an another ethernet cable from the router's lan port to my pc, I see there is an activity between the lan port of the router and the PC but none on the wan port, my ISP has only provided me with the cable and the IP settings, no modem.

After this when I try to access the web interface by typing the 192.168.1.1 in the browser, I receive error messages the I'm not connected to any network, so I can't even configure my wifi also, I have followed all the steps mentioned in the manual of the router:
A. Disable the proxy server, if enabled.
B. Set the TCP/IP settings to automatically obtain an IP address.
C. Disable the dial-up connection, if enabled.

if I plug my ISP ethernet cable to my computer directly, I have no problem accessing the internet. However, when I plug the computer into the router and the router into the ISP cable, my computer can't get on the internet. I know the router is functioning because I can access it using my android phone, and I can go to 192.168.1.1 and make changes to the router. On my computer, I can't even access 192.168.1.1.

When the computer is plugged into the router, the only IP address they receive is some slug address (169.254.xx.xx) that does not work. Windows 7 reports that the computer is plugged into an "Unidentified Network."

I have also removed my norton antivirus and turned of the windows firewall, but still no use.

I'm stuck people, help me here.

Thanks & Regards,
networkKiller :??:

I would connect your computer to your router with an ethernet cable. Make sure you go into the properties of the wired ethernet connection and make sure the IP4 properties are set to "Set the TCP/IP settings to automatically obtain an IP address", or DHCP. If done correctly your PC should get an IP Address from the router.

Thanks for the reply @abailey, I have also tried using static ip's but they too don't help and when i try to do ipconfig /release then ipconfig /renew I get an error on the ipconfig /renew command that states that "An error occurred while renewing interface local area connection: unable to contact your DHCP server. Request has timed out" I have checked in my services.msc and DHCP is fine and running but still somehow its not able to communicate, any views???

But it works in the wifi mode perfectly, I only have 2 issues with this router:
1. Lan connects with pc but gives unidentified netwrk with ip as 169.x.x.x
2. When I connect the ethernet cable from my ISP, I don't see any activity on the WAN port.

I have tried the following:
1. Resetting the router multiple times
2. Only connecting the Lan to check for connectivity(have tried through all the 4 ports available on the router)
3. Giving my pc static ip's and the pinging to the router, it fails
4. connecting to the router using android phone through wifi and everything works perfect.
5. Connecting multiple wifi devices to the router and it works.
6. Updating my Lan Driver, no use, still fails to assign an ip from the router over lan.

Ok now wan port of the router not detecting my internet cable from the ISP has been resolved by placing in between a D-link switch, so no the connection is like this internet > switch > router > to my devices but not to my pc, somehow router can detect the pc but can't assign it the ip. For now my temporary solution to get the pc also the internet is to connect it to the switch. In this configuration here is the route table with the static ip(The router changed it's ip address from 192.168.1.1 to 192.168.2.1 after it detected the wan network, so I also assigned the IP for my PC in the same range):
route-table-static-png.43611


and here is my current ipconfig:
capture_static_ipconfig-png.43612
