PPPoE issue - Flint AX1800

Jounouchi · December 17, 2021, 1:31am

Hi all,

Will like to check what is the issue of this?
Basic info: My ISP required to have 500 vlan for internet connection and 600 for iptv. I somehow managed to create the vlan through LuCi, however today perform a restart face this issue again, it was facing the same error initially when I setup Flint AX1800.

Below are the logs:

Hi, I’m not sure luci can handle setuping up vlan interace on flint.
You better edit /etc/config/network, internet connection interface should be like this,

config interface ‘wan’
option hostname ‘GL-AX1800-d40’
option metric ‘10’
option proto ‘pppoe’
option username ‘my_username@isp.net’
option password ‘my_isp_password’
option disabled ‘0’
option ifname ‘eth0.500’
option ipv6 ‘0’

Could you tell what your setting of iptv interface?

Btw, “Timeout waiting for PADO packets” is more like link layer problem, you can try restart modem also.

Yes, you can setuping up vlan interface on flint

Luci → Network → Interfaces → Wan → Edit → Physical Settings → Custom Interface: eth0.500

It works for me

I tried restart router and it works again, I am not sure what is the issue that causing this. Same error too.

This is my current setup.

Do you have a configuration backup( at luci http://192.168.8.1/cgi-bin/luci/admin/system/flashops) when it works, and check the difference when It doesn’t work.
