Firmware should always set the upstream ethernet link to wan[0,1]_pppoe_mtu + 8, not wan0_mtu which is set by WAN page another type other than PPPoE.
This doesn't happen 100%, usually after running for a while/disconnect by ISP then reconnect for a few times. Confused me for a long time because just a reboot solves the TCP drop packet issue, but after a few days, it started to fail again.
