The monitor local to the DVR (in a cupboard in the house away from my office) is connected with a simple video coax cable.

This any help? http://www.youtube.com/watch?v=OG9UuEaocz0

Hi again,

Thanks for the link. It's actually a vid I have lready referred to. I do everything it says but after I have added the device serial number it eventually puts a red cross on the device icon and states that it is offline. I have checked and double checked the serial number and I think it's correct. Very frustrating!

Can you ping the DVR local IP address?

What ports does the software on the DVR use and can you see any evidence of it listening on those ports?

My preference would be to ensure things are working with the DVR and PC connected to the Asus routers switch ports first, before introducing the access point into the mix.

If I log into the router and ping the DVR IP address I get the following:

PING 192.168.1.10 (192.168.1.10): 56 data bytes

I looked at the DVR network setup and it was using HTTP port 80. I read somewhere that this was not ideal and followed thier example and changed it to 88. Can't say it has made any difference.

How would I know if the DVR was listening?

Can you ping that IP address from the PC?

To see if a TCP port is listening

telnet 192.168.1.10 80
or
telnet 192.168.1.10 88

It will connect and just give a blank screen but that confirms the TCP port is there and listening.

How did you "look at the DVR network setup"?

Pinged my own pc from my pc followed by pinging the DVR:

I went to the DVR and looked at network setup on the attached screen.

Has the DVR got the correct default gateway address?

Might be handy if you paste the entire IP configuration.
