Can't connect PPPoE session: Send PPPOE Discovery V1T1 PADI session 0x0 length 12

Installing and Using OpenWrt Network and Wireless Configuration
1

hi, I have been trying for a while to get my OrangePi R1+ LTS to connect by PPPoE, but I just can't get it to connect. I read about create a VLAN (802.1q) device of the interface which will connect by PPPoE, but didn't fix the problem.

When i try to connect it just kept with the message "Send PPPOE Discovery V1T1 PADI session 0x0 length 12".

Same device with Debian image connects by PPPoE, but at 40/40Mbps, and I want to reach the contracted speed 900/600Mbps, because my actual router, a TP-Link C5 (1 core) only gets 220/380Mbps with Software Offloading.

Are you sure your ISP uses VLAN 1?
How is the configuration like, on the devices that can stablish a connection?

Hello,
I tried with eth0.2, but same behavior. Eth0.2 is the one which works on my TPLink C5 witch OpenWRT.

Hi

maybe this is a problem
without further details, my guess is:
eth0.2 is used in swconfig to separate WAN interface
so, you misunderstand .2
it is not VLAN, it is virtual WAN interface
please try with plain ETH0

option ipv6 'auto'
option device 'eth0.1'   <-- eth0
option mtu '1492'

config interface 'wan6'
option device 'eth0.1'  <-- eth0
option proto 'none'
option auto '0'

config device  <-- remove
option type '8021q'  <-- remove
option ifname 'eth0'  <-- remove
option vid '1'  <-- remove
option name 'eth0.1'  <-- remove
5

hi, I tried with the WAN device as eth0, but were same as using the VLAN at 1 or 2. I will remove the VLAN, so we can try something.

yes, i was right ... plain WAN interface

it should be plain eth0

looks correct

7

Anyway, it's not possible to reach a session of PPPoE, getting only PADI. Any idea how to continue digging on this?

8

Hi

as you see, there is no need to use VLANs, so maybe you make more mistakes when tried to configure your OWRT.

my suggestion is to reset OWRT to factory defaults
and without other tinkering, configure eth0/wan/pppoe

9

How do you know? The ISP might vety much expect the use of a specific VLAN by the enduser....

10

Hi

look at his config
working config from old OWRT on C5
please read whole tread

11

The actual config only have the user and password for PPPoE session, but anyway I get only PADI timeout... It's using eth0 as WAN, but same as eth0.2, only PADI timeout.

12

This phenotype really just means your pppoe client can not communicate with the server without detailed diagnostic value.
Could you post a link to your ISP's website, please, maybe it contains some pointers on configuration...

Even when I can connect with the OrangePi using a Debian OS ?(but only gets 40Mbps)

The company is www.movistar.cl

14

Yes, even then... sure as @NPeca75 indicated my VLAN approach was wrong anything else from a disconnected ethernet cable to a VLAM mismatch (not your problem) will cause your problem, ypur router sends a request, and does not receice a response...
What the debian test shows is that your username and password seemscorrect and that the physical hardware seems okay.

I want to add, my device, the OrangePi R1+ LTS, were included in official support by OpenWRT since 23.05.0-rc2 (release date 28-06-23)

16

It can be things like the logical interface names not matching the printing on the case, and this mapping of physical ports to logical interface names can easily differ between OpenWrt and Debian; I am mot saying this is your issue, just that things often are not straight forward....

17

this is when trying to connect:

ifconfig eth0 hw ether and cloned the MAC address from the router who works.

root@OpenWrt:~# pppoe-discovery -I eth0.2
Access-Concentrator: NE40-BRAS
AC-Ethernet-Address: 44:a1:91:29:d4:fe

even that, the router who doesn't work, can't discover company concentrator.

root@OpenWrt:~# pppoe-discovery -I eth0
Timeout waiting for PADO packets

Your are not getting a single packet back, no wonder the pppoe negotiation fails...
