We have a SOHO that up until now had the following setup - Billion BiPac 5200S ADSL modem connected to a standard 8 port 10/100mbps mini-switch. A Canyon CN-WF514 wireless AP is connected to one of the ports on the mini-switch providing wireless signal for laptops, smartphones etc. We also have a linux box running as a file server. The Billion provides the DHCP server. The Billion is 192.168.0.1, file server 192.168.0.2 with the pc's / laptops receiving IP addresses when they connect. Our printers are on 192.168.0.80 and 192.168.0.81 and the wireless router on 192.168.0.99

I've recently got a TP-Link WR2543ND which I'd like to add into the mix. I connected the Billion to the WAN port of the TP-Link (with IP 192.168.0.98) and it forced a change in it's IP address to 192.168.1.1. When I try to change it back I get an error that the LAN and WAN IP's cannot be on the same subnet.

What I'd like to have is the Billion connected to the WAN port on the TP-Link. The 4 (gigabit) ports on the TP-Link will then be for the file server, 2 pc's and the 8-port mini-switch. The printers, some other pc's and the Canyon wireless will then run off of the 8 port switch.

What would be the best way to set this up ito DHCP server, IP addresses etc.
 
Can't you set it up for bridging to act like an access point?

It doesn't seem to have a bridge mode. Connecting the modem to one of the gigabit ports feels like a waste of a port (there are only 4)
 
The WAN port is intended for PPPoE connections made by the TP-Link via a modem. As far as I'm aware, you cannot use it as a standard network port.
 
Hang the tplink off a normal switch port. You can't use its wan port as a LAN port.
 
I would connect the Canyon CN-WF514 to the TP-Link so they all use the same address range. So the wired clients would use 192.168.0.0 network and the TP-Link & Canyon use 192.168.10.0 network.
 
Thanks for all the suggestions. I realised that not only are very few of our 802.11n devices 5Ghz capable but I get far better connection speeds on 2.4Ghz. So I tossed the Canyon and set the TP-Link to 802.11bgn mixed on 2.4 Ghz.

The setup is now that the Billion is connected to the 8 port mini-switch, as is the TP-Link, our printers and a couple of PCs. The file server and two other (gigabit capable) PC's are connected to the TP-Link.

Everything seems to be working now.
 
Just keep in mind your wireless speed will default to the slowest connection, i.e. if you have a laptop connecting at 802.11b and you have one connecting at 802.11n,then the router will default to 802.11b and all devices will be throttled down to this speed.

I'm not sure how TP-Link devices handle this, so it might not be an issue, but it more than likely will be.

You sure about this? First time I've heard of it.

Yip. There's a Cisco Whitepaper on it somewhere, I'll find the link.
It might be only with the 802.11N draft devices, I honestly don't recall. I just remember we experienced issues like this with several of the networks we installed.

That sucks! Anyway, we have a couple of n and g devices connected at the moment and my laptop says transmit rate is 78 (I'm 4 offices away from the router) so it seems to be connecting at n despite the g presence on the network.
