Connecting a 7800DXL and 7800N with LAN Ports

Post by Theodore » Mon Jun 18, 2018 4:32 pm

Hi,

I have a really annoying problem which is driving me mad. I have a FTTC broadband connection which uses the ISP supplied router as a modem. This is connected to my 7800DXL which is the heart of my network and my DCHP server. I want to repurpose my old 7800N as a wireless AP and desktop switch. I would normally connect the 7800N EWAN port to my network and set it to bridge mode but the EWAN port is only 100Mb and with a CAT6A network I can't bring myself to compromise on that.I have read elsewhere that I can connect the 7800N via one of the LAN ports. My problem is that both routers have the same default IP address, 192.168.1.254. I would like the 7800N to take its IP address from the 7800DXL's DHCP Server but so far I haven't had any success. I have tried assigning the 7800N's IP address manually, outside the 7800DXL's DHCP range to avoid the conflict but it is still not playing ball.

Please help.

I didn't find the right solution from the Internet.

Thanks!
1. Change the IP address of the 7800N to 192.168.1.200 (outside the DXL DHCP range)
2. Disable the DHCP server on the 7800N
3. Plug a Ethernet cable from the 7800DXL to the 7800N ports 1-4 can be used
4. Restart any devices that are connected to the 7800N (to renew the IP address, as the 7800DXL will issuing IP addresses and deal with the routing)
