Redmi AX6000 won't connect to internet

[#1]

The username will be as the VDSL (FTTC) connection as will the password (BT doesn't need credentials but Plusnet does).

Assuming the WAN interface is the port you think it is (I assume "dsl0" - probably the first port) then it should work.

However if the setup is the same as the FTTC plus Openreach (copper) modem and that was "dsl0" it should be the same physical port again.

I would also power everything down then power up starting with the Openreach ONT and then the router once the ONT is happy.

@Skuzzer   this thread is getting very confusing as we have no idea which post you are replying to, It would be worth you starting again with a bit more detail on how it was working and what you have done, and why you have chabged things,.

You username on PN is not the generic BT one so not surprising that your config is not working. You need to use the same ure= username as in the PN router. ending in Plusdsl.net or similar

[#3]

Problem may be the change of leads. Now connected to socket 1 (WAN) and not to socket 3 (LAN). Only socket 1 gives all LED's lit like it was before. Leaving in socket 3 the LED's for internet remain unlit. The display for WAN interface say unable to connect.

@Skuzzer according to the Openwrt wiki here https://openwrt.org/toh/xiaomi/redmi_ax6000

Ports 1-3 are LAN ports , port 4 is the WAN port

Numbers 2-4 are Ports 1-3 as labeled on the unit, number 4 is the Internet (WAN) on the unit, 0 is the internal connection to the router itself.

Port	Switch port
LAN 2	1
LAN 3	2
LAN 4	3
Internet (WAN)	4

If that doesnt help , then export your network config and post it ( redacting any passwords etc ).

I've run Openwrt on my PLusnet FTTP connection for a few years now, so am pretty familiar with configuring it

MisterW suggested the following:- Here's my network settings

config interface 'loopback'
option device 'lo'
option proto 'static'
option ipaddr '127.0.0.1'
option netmask '255.0.0.0'

config globals 'globals'
option ula_prefix 'fd12:redacted::/48'
option packet_steering '1'
option dhcp_default_duid '000468b4redacted'

config device

list ports 'lan4'

config interface 'lan'
option device 'br-lan'
option proto 'static'
option ipaddr '192.168.1.1'
option netmask '255.255.255.0'
option ip6assign '60'

config device
option name 'wan'
option macaddr 'cc:d8:redacted'

config interface 'wan'
option device 'wan'
option proto 'pppoe'
option username 'user@plusdsl.net'
option password 'password'
option ipv6 'auto'

config interface 'wan6'
option device 'wan'
option proto 'dhcpv6'
option reqaddress 'try'
option reqprefix 'auto'
option norelease '1'

I'm running Redmi AX6000 router with OpenWRT software. This was working on FTTC not on FFTP. Connected to WAN (1)

Network settings says Error: Connection attempt failed followed by Error: Unknown error (AUTH_TOPEER_FAILED). Any ideas?

[#6]

@Skuzzer 

Connected to WAN (1)

Which physical port is that ? The Openwrt wiki suggests that WAN is port 4.

option username 'user@plusdsl.net'
option password 'password'

I'm guessing that is just info being redacted but to confirm 'user' above is your account name and 'password' is the one used to access the member centre ?

option ipv6 'auto'

Plusnet does not currently provide ipv6 so that line should be 

option ipv6 0

and you should disable the wan6 interface

If that doesnt help then can we see the PPPoE events from the system log please ?

edit: you might want to uncomment the debug line in /etc/ppp/options to get more information in the log

[#7]

The log is pretty big, do you want it all?

[#8]

No, just any related to pppoe. Basically anything logged from 'pppd'

Simplest way is to ssh into the router and then run 'logread  | grep pppd' 

That should give just the pppd logs

You've got no physical connectivity on the WAN interface. Are you sure you're using the correct port on the AX6000 to connect to the ONT ?

[#11]

Really weird going on. I put the connector in LAN4, no internet LED's (4 for power, 4 for internet access) but while I was having dinner the internet access on my PC was normal. However still no connectivity. Only when in WAN1 do I get the internet LED,s flashing. When I look at the LEDE computer overview & Network wireless, it seems normal. Only the Interface shows Unknown error. I've tried playing around with settings to no avail

Interesting thing, when the BT man had done his bit, the Plusnet Two router didn't work either. A quick reset was all that was needed there.

[#12]

When I look at the LEDE computer overview 

Do I take it from that you are running LEDE i.e an older fork of Openwrt ?

It could well be that the port assignment for WAN is different on a pre-DSA implementation.

Only when in WAN1 do I get the internet LED,s flashing.

So what's the log look like when connected to port 1 ?

[#13]

I'll have to get back to you if I can recreate it. I did have a quick look & it was a whole lot different, a lot more stable.

I'm running version 24.10.5, was running 25.12.1 but has made no difference.

[#14]

I'm running version 24.10.5, was running 25.12.1 but has made no difference.

Those are official Openwrt versions, 25.12.1 being the latest release.

In that case AFAICS port 4 should be the WAN port according to the wiki.

[#15]

Not been able to reproduce. I'll be in touch if I get anywhere....doubtful. If I don't get anywhere I guess it's just the Plusnet from now on. I don't really need the extras on OpenWRT other than it is up to date unlike the Plusnet Two.

Thanks for your help anyway
