What should I do if I fail to do PPPoE on EW Mesh Wi-Fi?

Topology: ISP modem --- EW3200GX PRO1.
1. You can connect your PC to ISP modem directly and configure PPPoE on your PC, which is supposed to check whether your PPPoE account is normal or not. If you fail, you may contact the local ISP for account issue.

2.If the ISP has done the relevant MAC binding, so when your PC directly connected to ISP modem can access Internet via PPPoE, then the MAC address of WAN port on EW3200GX PRO can be modified to the MAC address of the PC network card. (The way to modify: More> Basics> WAN> Advanced Settings>MAC)

3.If the ISP's PPPoE server requires the MTU value to match, you may change the MTU value of the EW3200GX PRO's WAN port to match the ISP's side. (The way to modify: More>Basics> WAN> Advanced Settings>MTU)

4.If the ISP has requirement for VLAN, you may need to enable 802.1Q under the WAN port of the EW3200GX PRO. (The way to modify: More> Basics> WAN> Advanced Settings>802.1Q)

5.If you have tried all of the above and still can't get IP address, you can use the packet capture feature in EW3200GX PRO. Capture a packet on the WAN port and send it to us for analysis. (The way to capture: More> Diagnostics> Packet Capture, Select WAN as the packet capture interface and No limit as the Packet Count Limit)
