My PPPoE connection shuts down in the evenings.

Network topology
ISP > TP-Link TD-8616 ADSL2+ Modem at 192.168.2.1> Router GL.iNet GL-B1300 at 192.168.1.1 >Wireless Devices

Sadly Timeout waiting for PADO packets is the most common error message for PPPoE links, by itself it doesn't tell you a whole lot. But many (most) xDSL did (and some still do) enforce a 24h disconnect with changing IP addresses over here, to discourage server uses (by changing the IP address) and kicking inactive devices off the net, are you sure that this isn't an issue with your ISP?

To check this, I'd look if it always fails at (roughly) the same time each day - and then reboot (well, restart the WAN connection, but rebooting might be easier for you) once in the morning (or some other distinct time of day) and then check what happens the next day (does it reconnect exactly 24h after your reboot or is it still only failing in the evening).

Here is a recent thread about PPPoE disconnects, but I do not know if it is the same issue though: PPPoE disconnects every few hours . Did you search the forum?

I update over wireless all the time; never an issue.

That issue would trigger often, but shouldn't always happen around the same time of day, therefore my first suspicion would be on 24h disconnects.

@fantom-x I did search the forum, but didn't find that post. From there, I learned the PPP debug option. The rest is to advanced for me to understand. Thanks.

By default, wireless is deactivated after a new install. How do you cope with that? Do you check "Keep settings" checkbox?

@slh The PPPoE seems to fail always around 22:00. It seems to reconnect but keeps dropping. Only when I wake up the next morning do I have the internet back.

19.07.0 has a vulnerable ppp client. Definitely update ASAP. See: https://openwrt.org/advisory/2020-02-21-1

Any ideas what I could do? If not, then I will buy a configured Router from my Internet provider.

How do you fix this when it happens? Does it just recover some time later?
Does it work after rebooting the modem or the router?

It just works again the next morning.

In the evening, nothing got the connection back so far. I tried these steps:

  • Reconnect WAN Interface in Luci
  • Restart Router
  • Restart Modem.

That seems to imply your ISP's end of the PPPoE link....

Ok. I will check with them.

This error (Timeout waiting for PADO packets) occurs when ISP's side does not respond to your router's request to establish a connection. Often it happens when the previous connection was not properly terminated, and ISP's hardware does not expect (ignores) requests from the client's side.
You can either talk to your ISP and show them the logs, and/or set your router's crontab to automatically reboot when connection is lost.

Alternatively, you have regularly scheduled radio interference. In my own experience, it was a bad (but otherwise still working fine) LED bulb on a timed switch about five meters away from DSL modem/line that was overwhelming the signal with noise.

Is Google banned in your country?

It is usually assumed people read though OpenWrt User Guide before posting questions here.

The problem is that I have to go to Google, post the question there, copy the first link, and paste it here... exactly the same that you could have done yourself.
