Adding A modem to an existing router / wifi network

[smarkgee]

I have a gigabit switch that is the centre of my gigabit wired network.

to that I have a router which acts as a DHCP server (gives out IP addresses) and modem to connect to the internet AND as a wifi connection point.

I also used your rather excellent article (as follows) to add a second wifi access point so that my wife can work in the shed at the end of the garden ;-)

the problem I have now is that everything the kids get is wireless so the wifi-router-modem is getting a bit overloaded possibly handling lots of wireless requests while I am trying to watch the iplayer.

I have a spare wireless+wired router/modem. I want to make this wireless router into an ADSL2+ modem only. D-Link 2680. So freeing up my existing Wi-Fi router/modem to focus on serving wireless requests and handing out IP addresses. Also then I can plug the spare/new modem directly into the BT point which may also increase my net speed.

192.168.2.1 - main router and gateway
192.168.2.1-192.168.2.199 range of Ip addresses handed out
192.168.2.200 - wireless access point
255.255.255.0 subnet mask
8.8.8.8/8.8.4.4 google DNS servers
192.168.2.250??? - spare router/modem

A good solution in principle methinks BUT...

I'm not quite sure exactly what to do next. I think I want to make my spare wireless modem into a modem-bridge?? with wireless and dhcp both turned off. I can sort of do that and it connects to the internet but does not seem to be part of the network. So nothing else can see the internet

I've tried adding 192.168.2.250 as a secondary gateway but that doesn't seem to work

OK, I may not understand this, but it seems like you want to remove some of your kids traffic from the main wireless network?

Just set up your 2nd wireless device with a different SSID, and plug one of it's LAN ports into your network and have your kids connect to that SSID. Done. Once you configure it you don't even need to assign it a LAN IP address on the same network, but it will make it easier to administer later, so make it 192.168.2.254 or whaterver. WAN side won't matter.

DHCP will still be handled by the main router which will also be the default gateway, but it won't matter.

ADDED: Just realized what I wrote is more of less what is posted in the link in your original post about turning a router into an access point. So, I must not understand your questions, but it still seems like you want to reduce wireless network traffic?

Please clarify what the problem is. What does adding a second AP to create a range extension for your garden have to do with "everything the kids get is wireless"?

192.168.2.1 - main router and gateway
192.168.2.2 (two)-192.168.2.199 range of Ip addresses handed out
192.168.2.200 - wireless access point
255.255.255.0 subnet mask
8.8.8.8/8.8.4.4 google DNS servers


I want 192.168.2.1 to just be a modem connected to my switch (no ip)
I want 192.168.200 to be the dhcp server and (ip handing out and resolving for the internal network)

when I change the gateway setting in the physical piece of hardware that is 192.168.200 to the setting 192.168.2.1 then nothing works. I also change the dhcp server functionality from xx2.1 to xx2.200

I don't want a typical home setup where the router is handling and managing all traffic and handing out and resolving ip addresses

clear as mud ;-) ? :-(

ty guys

2.200 is your current AP and is still going to be your AP when you are done, correct? If that is true, you aren't solving any bottlenecks with your wireless network by doing this.

But to your question, your main router/AP that will be your dhcp server would need to be able to be capable of assigning a different IP address for the default gateway other than it's own IP address. If it will not let you do that, then what you want to do will not work.

If I understand and you have congestion on your wireless network, then just give the kids their own wireless network.

ADDED: These are the settings for what you want to do [though I don't understand why :]

1. Set LAN address of modem/router to 192.168.2.1, 255.255.255.0, 192.168.2.1 [IP, subnetmask, default GW]

2. Set the LAN address of the AP to 192.168.2.200, 255.255.255.0, 192.168.2.1, and plug one LAN port into your network... leave the WAN port unconnected.

3. Set the DHCP server in the AP to give out 192.168.2.2-199, gateway of 192.168.2.1 and dns of 8.8.8.8, 8.8.4.4.
