VLAN breaks Ethernet Broadband

[seud0nym]

Hi @seud0nym,

Sorry to hijack this issue, looks like I also have a problem when trying to set up VLANs.

I've just tried running VLANs from the Local Network screen however it disconnects my WAN connection straight away and switches over to the mobile backup. I have a PPPoE connection for my WAN

I also noticed that in the broadband card it shows "VLAN 1" as active. If I go into that card the VLAN settings have been switched off so it must be pulling it from the local network card (might be a clue to follow)

If I switch VLANs off it reconnects straight away

Big fan of you and what you've done so far with these modems, it's awesome!

Thanks again for your help

Firmware Version: 20.3.c.0432-MR21.1-RA

[seud0nym]

Can you please post the output of the following commands (when you have VLANs enabled):

transformer-cli get uci.network.interface.@lan. | sort
transformer-cli get uci.network.interface.@wan. | sort
transformer-cli get uci.network.device. | sort

[seud0nym]

I forgot a command. What is the output from:

mdkshell vlan show

[gingerninja234]

Sure, here are the results

Looks like it has deleted my PPoE username and password (from the output of uci.network.interface.@wan.). Maybe if I enter them it might work again

EDIT: Nope that didn't work, PPoE login must have disappeared when I did reset-to-factory-defaults-with-root

[seud0nym]

That is very helpful. This is the problem:

uci.network.interface.@wan.ifname [string] = vlan_eth4_1 

It should be eth4 not vlan_eth4_1, so it looks like I have incorrectly updated the WAN interface, instead of limiting my updated to LAN interfaces. Unfortunately, it will probably do that every time you enable or change VLANs, so best to turn it off at the moment. That will revert it back to eth4.

[gingerninja234]

Awesome! I see, I had a feeling the interface may have got renamed

Will keep VLANs off for now, otherwise the internet doesn't work 😝

[seud0nym]

I have committed the fix. If you want to try it, you can do update with this command:

./tch-gui-unhide -u && ./tch-gui-unhide -y

[gingerninja234]

It works! Thank you for the quick fix! :)

Fixed in stable release 2023.06.23
