Problem with 2x ASUS RT-N56Us

Hi guys!

Got a problem on my network which I can't seem to shake off. Any help would be greatly appreciated.

Got 2x ASUS RT-N56Us.

1st one in the house is setup as 192.168.2.2 with a Draytek Vigor 120 Modem plugged into it. Latest Firmware installed.

2nd one in the studio is setup as 192.168.2.12 and in 'Access Point Mode'. Older Firmware installed.

Now, whenever I plug in the studio ethernet at the house, I have full access to internet/network @ the studio. However, we then lose the house connection (all the computers/devices have what seem to be IP problems and lose connectivity).

As soon as I unplug the Studio ethernet at the house, everything returns to normal.

I have several devices on the network (both at the house and in the studio). I have manually assigned all the IPs of every device.

Must be a setting I have missed - are there any obvious ones you guys can think of?

Thanks in advance

Tom

Part of me is thinking it is IP related as the AP is within the 1st router subnet.

Yer, this is what I keep thinking too.

I remember my old Netgear router would have to be put in 'Bridged Mode' for this sort of setup - is there a similiar thing I need to do to my routing RT-N56U?

Your modem and router shouldn't be on the same IP range (not sure if it makes a difference though)

I personally would put modem on 192.168.2.1, House Router to 192.168.0.1 and Studio Router to 192.168.0.2

Disable DHCP on the studio router, set the DHCP range in the house router to start at 192.168.0.5 (room for expansion) then plug the ethernet cable from the house router into the LAN side of the studio router

You should then be able to access the router settings of both RT-N56U's by typing in there IP address from any device.

Thank you for the reply Ryan - I will give that a go when I get back home.
I didn't realise they should all be on different IP ranges.

Am I right in saying that the DHCP is only for devices which are not set manually within the network? Ie. Guest iPhones/Laptops etc? Or does DHCP need to be enabled across the board to even get connectivity from clients which have manually set IP addresses?

Thanks again for the reply - in a bit of a pickle here!

You don't need DHCP if you are setting manual IP addresses for everyone, but it does make things easier if you want to allow someone access quickly

And, Thats how I have mine set up at home, Modem = 192.168.100.1, Router 1 = 192.168.10.1, Router 2 = 192.168.10.2, Router 3 - 192.168.10.3

Can't thank you enough Ryan. Seems like following your instructions has fixed the connectivity issues we have been experiencing.

I will report back if there are any further complications.

Thanks again dude!
