How to add a router to the CG3000

I have very poor wifi reception in one part of my house. I have run a cable to that area and plugged in a spare Wireless router. I turned off the DHCP Server. Gave the box a different IP address to the main CG3000. According to several articles on the internet (eg http://www.ehow.com/how_6883934_use-router-range-extender.html ) this should work. However it does not. I came across another article which stated that the CG3000 was deliberatly prevented from doing this. Can anyone confirm this, or suggest how I can get wifi into the dead area (preferably without spending any more money!).

Thanks for any help or suggestions.

Re: How to add a router to the CG3000

Fair question - My understanding is that the cg3000 has the ability to use DHCP or hard coded.

In either case you can not have 2 DHCP servers on the same network, it's just reject IPs.

I guess if I had to do it, I'd actually keep the DHCP on the cg3000, this would in theory propergate onto the secondary device, this this device in turn needs to be configured as a pass through .. so I would hard code an IP onto the actual laptop/computer etc but that IP must be within the 192.168.0.10 - 209 range.

Give it a go, reply back with make and model. Optus can not help you here as it is beyond their support boundaries

Re: How to add a router to the CG3000

You need to put the modem in bridge mode: http://192.168.100.1/RgNatControl.asp

 

Untick the box that says "Turn NAT on"

 

Then you configure your router to EWAN (or similar name depending on your router).

 

 

(I don't believe you can turn off DHCP on the CG3000 - it's very dumb and very bad!)

Re: How to add a router to the CG3000

I have this set up with another Netgear WiFi Router set up as an Access Point.

 

I didn't touch the CG3000.

 

I followed the instruction for setting up AP on the other Netgear.

 

Turn DHCP off on the second router.

 

Assign a fixed IP on Second Router from the CG3000 range eg 192.168.0.100 (So you can manage second router)

 

Plug cable from CG3000 into one of the LAN ports on the second router NOT the WAN port.

 

This setup works fine for me, one network 2 routers with 2 SSID's and 2sets of  LAN ports.

Re: How to add a router to the CG3000

Thanks for your help and advice. I am not terribly well informed about this kind of thing. Can you tell me how the second WiFi router manages to supply in interenet connection if the line from the main router is not plugged into the "internet" socket? I have tried plugging into one of the Lan sockets but cannot connect to the internet.

Re: How to add a router to the CG3000

My tip is do not mess with the CG3000 settings as the reset button does not actually reset the modem.

 

I have this set up to an old d-link router.

 

CG3000 stock settings.

 

My D-link, set the wireless password, changed the IP to 192.168.0.100

 

Turned off it's DHCP AND also before it would work I had to disable something called DNS relay. I was stuck with that for a while.

 

Plug one ethernet end into an ethernet port on the CG3000 and the other end into the ethernet port labeled number 1 on the other router.

 

IMPORTANT power cycle all equipment or it will not detect the new router. to do this you turn off all computers. unplug both routers from the power point. Plug the CG3000 in and wait a few mins for it to fully boot, then plug the other router in wait for it to boot. then turn on your computer and as long as the PC's trying to connect to the router do NOT have a static Ip that is the same as 192.168.0.100 or 192.168.0.1 it will work.

Re: How to add a router to the CG3000

To answer your question how it is supplied with internet, Turning off the DHCP setting on most routers will turn it into an access point, this means the CG3000 deals with all connections, assigning IP addresses and handing out internet. The extra router is pretty much just an extension of the CG3000 now.

 

In my case for the D-link router I have, I had to turn off DNS relay to set it fully into an access point.
