Airport Extreme Settings using Zyxel P-660HW-T1 v3 Router

Hi. Have just returned to the UK from Singapore and am having huge difficulties with my Network. In SG I had a Cable modem, connected to a AEBS, set to distribute a range of IPs and create wireless network etc. THis was extended using another AEBS and Airport Express and I could use it all over no worries.

In UK I have had all kinds of probs with Double NAT issues, 'Another Computer is using your IP' issues etc. I am also now using Eye TV on a Mac Mini and have had to frig my settings to get it to talk to my iPAD.

My current set up is:
Internet through Phone line (Post Office ISP) to Zyxel P-660HW-T1 v3 wireless router.
Zyxel set up with NAT, UPnP, DHCP (as server) and connected to the AEBS (DUal Band) by Ethernet.
AEBS is set up in Bridge mode to create a wireless Network and connected to one Mac by Ethernet, One by Belkin Powerline connection and the others on the wireless network.
I have another AEBS extending this network.

I have had to set up the Zyxel as this in order that Eye TV can see the outside work and speak to my iPAD and also to prevent the double NAT issues.

However, the network does drop on occasions and when I re-wake my MBP (wirelessly connected) it often cannot find the internet (though it is on the home wireless network) and occasionally it tells me another computer is using my IP address.

To resolve these issues, I have to reboot the Zyxel or the AEBS.

I am sure I am over complicating things. All I want is to have a reliable network, be able to connect all the Macs and ATVs together and share media and to connect the EyeTV to the outside world and not have to reboot (or worse still talk my wife through the process) every day.

I have looked around for docs and cannot really find anything that tells me what settings I should use on the wireless modem and router. The post office prefers that the Zyxel handles NAT and I have the AEBS on Bridge but this seems so much more complex.

Finally, I just tried to change this again this morning and Airport Utility told me I had the wrong starting and ending IP when I switch it to share a Public IP

Apologies for the long post - Happy to provide any further info you may need to advise

All the very best to you for Christmas and the New year

Slacky, welcome to the discussions!

You want the device that is establishing your Internet connection...the Zyxel router in your case...to handle DHCP and NAT functions for the network. Any other routers on the network need to be configured in "bridge mode" to allow the Zyxel to function as the main router on the network.

However, the network does drop on occasions and when I re-wake my MBP (wirelessly connected) it often cannot find the internet (though it is on the home wireless network) and occasionally it tells me another computer is using my IP address.


The Zyxel router is in charge of DHCP (IP address assignment), so that is the place to look at first for issues relating to the errors that you are seeing. If you have made a number of configuration changes to the network, sometimes it is best to simply reset devices back to factory defaults and reconfigure them again. I can't say whether this will fix your issues, but it could not hurt.
