@dimfish @Ansuel Goog job guys

Dhcp works on each device/interface.

Do you need anything to be checked?

dimfish · 2024-11-08T17:03:44.291Z

Nice! Thanx for testing

It would be great to test vlans (on 23.05 there were problems)

OpenWrt support for Xiaomi AX3000T For Developers

I can't compile firmware with patches but: Add Winbond support. Add Foresee support. Add AN8855 support Add support - soft brick fix code after 7 reboots. These are the problems that are not solved yet - officially, but unofficially they are solved. Suppose AN8855 needs to wait until it is added to the kernel, but the rest can be solved now?

Add Winbond support.
Add Foresee support.
Add AN8855 support
Add support - soft brick fix code after 7 reboots.

1,3 can be considered solved, 2, 4 remain.

Not sure if this is a good vlan configuration but it works on @dimfish relase 15-10-2024, unfortunately it does not work for 08-11-2024.

EDIT:
tcpdump shows

tcpdump: unsupported DSA tag: mtk

Could u try creating vlans using the bridge vlan filtering option? My devices are running in prod i cant test it.

Example config:

config device
        option name 'br-lan'
        option type 'bridge'
        list ports 'lan2'
        list ports 'lan3'
        list ports 'lan4'

config interface 'lan'
        option device 'br-lan.99'
        option proto 'static'
        option ipaddr '192.168.2.1'
        option netmask '255.255.255.0'
        option ip6assign '60'

config bridge-vlan
        option device 'br-lan'
        option vlan '3'
        list ports 'lan2:t'

config bridge-vlan
        option device 'br-lan'
        option vlan '4'
        list ports 'lan2:t'

config bridge-vlan
        option device 'br-lan'
        option vlan '99'
        list ports 'lan2:t'
        list ports 'lan3:u*'
        list ports 'lan4:u*'

config interface 'iot'
        option proto 'static'
        option device 'br-lan.3'
        option ipaddr '192.168.3.1'
        option netmask '255.255.255.0'

config interface 'guest'
        option proto 'static'
        option device 'br-lan.4'
        option ipaddr '192.168.4.1'
        option netmask '255.255.255.0'

tcpdump shows

tcpdump has been broken for a while. I am on SNAPSHOT for a little over a month and NOT AN8855 and I've had the same error when I tried to troubleshoot my shitty ISP IPv6 configuration.

j0zzy · 2024-11-08T19:55:51.320Z

Does configruation look ok? Ping works PC<->router and tcpdump shows vlan40.

config device
	option type 'bridge'
	option name 'bridge-vlan'
	list ports 'lan4'

config bridge-vlan
	option device 'bridge-vlan'
	option vlan '40'
	list ports 'lan4:t'

config interface 'vlan40'
	option proto 'static'
	option device 'bridge-vlan.40'
	option ipaddr '192.168.40.44'
	option netmask '255.255.255.0'

config device
	option name 'bridge-vlan.40'
	option type '8021q'
	option ifname 'bridge-vlan'
	option vid '40'

Between pc and router u need untagged and get rid of vlan device, its redundant.

Should look like this:

config device
	option type 'bridge'
	option name 'bridge-vlan'
	list ports 'lan4'

config bridge-vlan
	option device 'bridge-vlan'
	option vlan '40'
	list ports 'lan4:u'

config interface 'vlan40'
	option proto 'static'
	option device 'bridge-vlan.40'
	option ipaddr '192.168.40.44'
	option netmask '255.255.255.0'

Hi,

I have two Xiaomi AX3000T configured with OpenWRT 23.05.5, the first one is configured as a router and the second one is configured as a dump AP. When I have an ethernet connection I get good results in the internet speed tests (close to 1gbps both download and upload), however when I have a WIFI connection (client near the router), the download speed is quite low although the upload speed is similar to a wired connection. I have performed the same test for a WIFI connection using iperf3 and I get good results for both upload and download (similar to the wired connection).

I understand that internet speed tests are not very reliable, which is why they are performed using iperf. Are you get good results from internet tests via WIFI, or you are in my place? I understand that internet speed tests are not very reliable, that is why they are performed using iperf.

I have to add that I have a little bit complicated configuration with 2 VLANs (Home and IoT), and two WIFI networks on each device (Router and AP) associated to each VLAN. Any solution?

Thanks very much for your time

Attached are results of the speed tests.

Wire connection Intenet speed tests:

Download - 709.44mbps Upload - 821.65mbps

WIFI Connection Intenet speed tests:

Download - 222.49mbps Upload - 836.18mbps

Are you sure?

This does not work.

config device
	option type 'bridge'
	option name 'bridge-vlan'
	list ports 'lan4'

config bridge-vlan
	option device 'bridge-vlan'
	option vlan '40'
	list ports 'lan4:t'

config interface 'vlan40'
	option proto 'static'
	option device 'bridge-vlan.40'
	option ipaddr '192.168.40.44'
	option netmask '255.255.255.0'

This works

config device
	option type 'bridge'
	option name 'bridge-vlan'
	list ports 'lan4'

config bridge-vlan
	option device 'bridge-vlan'
	option vlan '40'
	list ports 'lan4:t'

config interface 'vlan40'
	option proto 'static'
	option device 'bridge-vlan.40'
	option ipaddr '192.168.40.44'
	option netmask '255.255.255.0'

imkloon · 2024-11-08T21:26:44.559Z

Yes, but u didnt change (t)agged to (u)ntagged thats why.

list ports 'lan4:u'

imkloon · 2024-11-08T21:28:20.374Z

Have u enabled WED and HW flow offloading? That should fix it.
I have like 350mbps through 2 walls on 5G.
Edit: I'm running 24.10 snapshot.

j0zzy · 2024-11-08T21:48:03.982Z

This works. tcpdump shows vlan 40

config bridge-vlan
	option device 'bridge-vlan'
	option vlan '40'
	list ports 'lan4:t'

This does not. tcpdump does not show vlan 40

config bridge-vlan
	option device 'bridge-vlan'
	option vlan '40'
	list ports 'lan4:u'

That is correct, packets will have no vlan tag, and they will be regarded as vlan 40.

Ok, so conclusion is: VLAN via "bridge VLAN filtering" seems to work but it does not work when VLAN device (802.1q) is created as described here OpenWrt support for Xiaomi AX3000T - #2133 by j0zzy.

EDIT:
With mentioned configuration (VLAN device (802.1q)) there is traffic towards PC but it's untagged

I have enable HW flow offloading but I don't think I have the WED option. How can I enable that option?

Tnks

j0zzy · 2024-11-08T23:13:33.753Z

Just look for

mt7915e wed

For example this: Support for Cudy WR3000 - #41 by nicefile

echo 'options mt7915e wed_enable=Y' >> /etc/modules.conf

EDIT:
Checked WiFi speed (AX 5G 160Hz channel) with wed enabled and got 900 Mbps via iperf3 both directions.

imkloon · 2024-11-09T13:07:58.515Z

Thank you for testing! I have flashed it on both my routers and all seems in working order so far.
