How To Setup My Maxis Fiber Broadband Using TP-Link TL-MR3420 and OpenWrt

Today I want to share with you a setup of Maxis Fiber Broadband using TP-Link TL-MR3420 v1.2 and OpenWrt trunk version but this setup is not a 100% replacement to Maxis Thomson wireless router with phone. I will assume you have flash your TP-Link TL-MR3420 with OpenWrt trunk and install luci. I am using r33132 version. Below is how my connection looks like: –

Login into your OpenWrt and configure the switch VLAN on eth0 as below: –

VLAN 1 = CPU – tagged, Port 1 – off, Port 2 – off, Port 3 – off, Port 4 – off
VLAN 621 = CPU – tagged, Port 1 – tagged, Port 2 – off, Port 3 – off, Port 4 – off

After successfully apply the VLAN configuration above, goto WAN interface and configure the PPPoE username and password as below: –

Next, you need to select “eth0.621” VLAN interface as WAN like below: –

After successfully apply the WAN interface configuration above, goto LAN interface and select “eth1” Ethernet adapter as LAN like below: –

Now you need to reboot the TP-Link TL-MR3420 to have the changes apply and it will be able to successfully connected to PPPoE like below: –

Note: The ports label in black are not usable for Huawei EchoLife HG850a and TP-Link TL-MR3420.
