I have a problem in My Zyxel Router(P-660HW-t1 v2), WLAN light is not displaying and no manu of WLAN appears in Router Setup but sometimes it appear and after few minutes the router restarts and WLAN light again disappear. Tell me about any solution

Type 192.168.1.1 or 192.168.0.1 if the first one doesn't work. You can to Zycel's website to get information on the various settings that will apply to your application.

See the User Guide downloadable from here.

Page 75 covers WAN set up where you need to specify PPPoe as the Encapsulation method.

first you need to forward TCP ports in your router pls write down which TCP ports used for video , audio and control in your DVR and configure to forward this tcp ports in your router
it can be do one step using disable the DMZ and it will make less sequrity in your internal network

There is a reset button on the back of the router. You have to press it in for about 10 seconds. (While the router is on) This will reset the router to default settings. You will lose all security, and your network will be "Open". You will then have to refer back to the guide in order to setup your network security, and create a new password.
Here is a link to the guide.

1. you will have to reload the CD that came with router
2. go to the setup wizard and click in the information provided by you ISP ( Internet Service Provider)

Press the reset buttton and refresh it.

First thing you need to do is go to the mfg web site and download the latest drivers for your router. Windows Vista drivers are still primitave.
Make sure both computers are set in networking for sharing. Check these out and get back to me. If that doesn't work, get back to me.

It could be caused by interference by other nearby networks/devices. Try changing the wireless channel.

Network - NAT - Port Forwarding - Default Server, Put the IP of your CCTV Hardware/PC

This IP will accept connection on all ports.

I never did this yet so any success please reply.
