IPQ9574/AP-AL02-C4 no connection with internet

carlo1 · February 26, 2025, 6:51pm

Good afternoon,

I was assigned an OpenWrt project, but I have limited experience with the subject. I’m currently familiarizing myself with the documentation on the website, and I have a question. I’m unable to access the internet with my board, as shown in the photos. I configured the WAN port interface as a DHCP client, but it still doesn’t ping or obtain an IP.

I’ve attached some photos of the interface configuration for reference.

Additionally, here are the hardware specifications I’m working with:

Chip	Manufacturer	Primary Application
IPQ9570	Qualcomm Technologies, Inc.	Wi-Fi 6E routers and access points
QCN9274	Qualcomm Technologies, Inc.	Wi-Fi 6E access points
AQR8081	Marvell Technology Group	400 Gbps switches and routers
ARQ113C	Microchip Technology Inc.	Industrial Ethernet controllers

Any help or guidance would be greatly appreciated!

What we can see from your screenshot is that you don't have an address on the wan interface. But it is not necessarily clear why...

What is the upstream network (is it a home/lab network, or a direct connection to an ISP)?
Does the upstream network use DHCP for its connection method (vs PPPoE or static IP)?
Does the upstream network require a VLAN?
Does the physical link on the wan port (eth0) show that it is active?

In addition to the above answers, let's take a look at your complete config to understand more about the device in question:

Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:

Remember to redact passwords, MAC addresses and any public IP addresses you may have:

ubus call system board
cat /etc/config/network
cat /etc/config/wireless
cat /etc/config/dhcp
cat /etc/config/firewall

Judging from MAC address you can find many yuncore devices supported.

It’s a lab network, but we are already setting up a separate network to configure the ISP.
The connection method is a DHCP network.
The network does not require a VLAN for use.
Where can I check if the eth0 interface is active or not?

eth0 assignment doesn't look right.

but it's also unsupported.

It appears you are using firmware that is not from the official OpenWrt project.

When using forks/offshoots/vendor-specific builds that are "based on OpenWrt", there may be many differences compared to the official versions (hosted by OpenWrt.org). Some of these customizations may fundamentally change the way that OpenWrt works. You might need help from people with specific/specialized knowledge about the firmware you are using, so it is possible that advice you get here may not be useful.

You may find that the best options are:

Install an official version of OpenWrt, if your device is supported (see https://firmware-selector.openwrt.org).
Ask for help from the maintainer(s) or user community of the specific firmware that you are using.
Provide the source code for the firmware so that users on this forum can understand how your firmware works (OpenWrt forum users are volunteers, so somebody might look at the code if they have time and are interested in your issue).

If you believe that this specific issue is common to generic/official OpenWrt and/or the maintainers of your build have indicated as such, please feel free to clarify.

brada4 · February 27, 2025, 2:02pm

You have to remove eth0 from the unrelated bridge. (and try to port official OpenWrt to your device?)

carlo1 · March 6, 2025, 12:10pm

Good morning, and thank you very much for the guidance on the previous issues!

This board is a version that currently does not have support for OpenWRT. I installed a generic version to see if I could make it work.

Since it is not a configuration issue, I tried creating a new image using the Make development environment. In it, there were configuration options for the board model. The problem is that after creating the image, I get this error:

frollic · March 6, 2025, 1:00pm

you're not going from OpenWRT nor to OpenWRT, we have no idea ...
