Hi @JunTina . On secondary router, disable DHCP and NAT. Also, configure it as Access Point, or Dynamic IP, or Static IP. There's no user manual for these units so it's a matter of trial and error. The secondary router should show in the status display of primary router. Connect secondary router WAN port to primary router LAN port. ... View more

Hi David, Are you able to provide more information/details  on how to set this up especially for TPG supplied-modem?   I tried the following but still I can't get any internet connection via the Wifi of the secondary modem. My primary modem is VX220-G2v while my secondary modem VX420-G2v, both supplied by TPG.   1) On my secondary modem VX420-G2v, -I did a factory reset and logon as admin -In the INTERNET CONNECTION SETUP, the default userid is tpg_acs@tpg_acs and default password is tpg_acs. So I changed the userid and password to the same username and password that TPG gave me for the primary modem. -In the Network Settings, under EWAN, delete the Connection Type PPPoE" Then create a new connection type PPPoE with VLAN ID= 1. Enter the userid and password that was used in the EWAN settings of primary modem. -In the wireless settings, create a new SSID with suffix (or retain existing Wifi SSID if you want) -In the LAN SETTINGS, under DHCP, change the IP address of the modem from 192.168.1.1 to 192.168.1.5 Then disable DHCP and IGM snooping. Retain the address pool of 192.168.1.100 to 192.168.1.199. -Click SAVE and reboot the secondary modem. 2) On my primary modem VX2200-G2v,  EWAN settings are as follows: WAN Interface Name:pppoe_2_3 Internet Connection Type: PPPoE VLAN ID: Enabled VLAN ID: 2 Username: <my TPG username> Password: <my TPG password> Authentication Type: AUTO_AUTH IPv4: Enable LAN SETTINGS are as follows: IP address: 192.168.1.1 Subnet Mask: 255.255.255.0 IGMP Snooping: Enable DHCP: Enable DHCP Server is selected IP Address Pool: 192.168.1.100 to 192.168..199 Address Lease Time: 1440 Address Reservation Settings: MAC Address: < mac address of my secondary router VX420-G2v> Reserved IP Address: 192.168.1.5 STATIC ROUTING SETTINGS are as follows: Wan Interface: pppoe_2_3 +++++++++++++++++++++++++++++++++++++++++++++++ I then connected a CAT5 cable from the WAN port of the secondary modem VX420-G2v to the LAN port of the primary modem VX220-G2v. When I tried to connect to the Wifi SSID of the secondary modem from may laptop, I was able to connect successfully. However there is no internet on it. If I issued "ipconfig" on my laptop via CMD, I don't see the ethernet connection ip address 192.168.1.5.   ... View more
