We’re excited to announce that tcpdump is now fully supported on our DR5018S router board, bringing enterprise-grade packet analysis directly to your industrial WiFi 6 hardware.
🧰 Why Tcpdump Matters
Tcpdump is a powerful, command-line packet analyzer tool that allows users to:
Monitor live traffic on specific interfaces
Capture and filter packets based on IP, port, protocol, and more
Export logs for deeper analysis or compliance purposes
Debug intermittent network issues with precision
Now with tcpdump on DR5018S, you don’t need a separate laptop or tap device — your router board becomes the diagnostic tool.
📡 About DR5018S
The DR5018S is based on the Qualcomm IPQ5018 SoC, designed for advanced industrial WiFi 6 applications. It supports:
2.4G/5G concurrent dual-band
M.2 slot for LTE/5G modem expansion
Optional PoE support
Flexible OpenWrt/QSDK firmware environment
By adding tcpdump support, we’re giving system integrators, OEMs, and network developers more control and clarity at the edge.
📝 Documentation & Access
An updated user manual with tcpdump usage examples, interface configurations, and filtering tips will be released shortly. In the meantime, you can check out the DR5018S hardware details here:
Today we share a guide how to make COMPEX WLE3002HX module work well under Linux 6.1.99 and OpenWRT
LINUX:
1 – Use Linux 6.1.99 kernel version and add ath11k related drivers
2 – UseQCN9074/hw1.0/2.7.0.1/WLAN.HK.2.7.0.1-01744-QCAHKSWPL_SILICONZ-1 firmware version
3 – Copy the firmware to the directory/lib/firmware/ath11k/QCN9074/hw1.0/directory, as shown in the following figure
4. Load the ath11k driver successfully, and the kernel prints as follows.
5. Use ifconfig to check that wlan0 has been recognized.
6.Scan external WiFi using the WPA_CLI scan and WPA_CLI scan_desult commands, only 5G band WiFi can be scanned
7.Connect to the scanned 5G frequency band WIFI for normal communication.
8. According to the previously provided document, replace the relevant firmware. The document content is as follows, please use serial console:
1.cd /lib/firmware 2.mkdir ath11k && cd ath11k 3.mkdir QCN9074 && cd QCN9074 4.mkdir hw1.0 && cd hw1.0 5.cp /directory/of/bdf.bin ./ (repeat this step for all above files) 6.ln -s WLE3002HX_SPF11_4_2G.bin board.bin (for first attempt on symbolic link)
To change board data files after first attempt: Change to 2G: ln -s -f WLE3002HX_SPF11_4_2G.bin board.bin Change to 5G: ln -s -f WLE3002HX_SPF11_4_5G.bin board.bin
Please replace DBF completely, the file name needs to be changed to the name in your system as described in this file.
Please contact us and we will sned these files to our customers by email.
9. According to the understanding, WLE3002HX_SFP11_4_2G.bin needs to be soft connected to
/lib/firmware/ath11k/QCN9074/hw1.0/board.bin
OpenWRT:
Ultimately what we did was:
1. Deactivate ath11k-firmware from my openwrt custom builds
2. Get the verified firmware version from git – WLAN.HK.2.7.0.1-01744-QCAHKSWPL_SILICONZ-1 e.g. 2 files amss.bin and m3.bin
3. Never download/use board-2.bin from qualcomm firmware
4. cp WLE3002HX5G.bin /lib/firmware/ath11k/QCN9074/hw1.0/board.bin (instead of symlinking)
bonus – cron to recreate the fw folder with files from backup location if missin
so the /lib/firmware/ath11k/QCN9074/hw1.0 folder contains only 3 files: amss.bin board.bin m3.bin
bonus – startup cron to recreate the fw folder with files from backup location if missing
This way the adapter works fine.
Thank you for reading. Hope that this can help you too.
Please see our reference guide how to run QCN 9024 / 9074 DR9074-Triband module with our ath11k driver on Rockship board .
The driver is sensitive to the hardware, so we refer you to use the Rockchip board to try these driver. If you have a bigger project, then lets discuss on the driver issues or send us the hardware description and we would help you to develope the ath11k driver for your application.
in the compiled environment. This directory may not be available in the newly downloaded environment. You can compile the kernel to obtain this directory.
Compile the kernel so you can get a new kernel deb with ath11k_pci.
Secondly, the correct firmware of the WiFi card is also required to activate it, you can move our firmware (amss.bin, board-2.bin) to:
/lib/firmware/ath11k/QCN9074/hw1.0
and delete the amss.bin.zst and board-2.bin.zst from the directory.
Setup wireless on ubuntu
Download hostapd
you can download hostapd by use command:
sudo apt-get install hostapd
Use hostapd to create a wireless access point
First, you should turn off ubuntu’s wifi tool by this command:
sudo nmcli radio wifi off
it will block you wifi function unblock wifi by use this command:
sudo rfkill unblock wifi
You can setup an access point by using command:
sudo hostapd hostapd.conf
hostapd.config is a configuration which has set the type of wi-fi you want to enable and the following figure shows its typical structure:
I have marked the most important part with a red box, where ssid represents the name of the wifi and interface represents the device selected to enable wifi. By the way if you don’t know your interface name, you can use command: ip addr which can show you the information about the interface, the wireless interface always seem like wlan* or wlp*.
If you see following output after you use hostapd command:
this means you have successfully started the AP.
And when you see this:
it means a device connected to you access point.
This also means connect if you not set password:
Use wpa_supplicant to connect a access point
First, you should turn off ubuntu’s wifi tool by this command:
sudo nmcli radio wifi off
it will block you wifi function unblock wifi by use this command:
-i can set the interface you want to use to connect. wpa.config is a configuration which has set the type of wi-fi you want to connect and the following figure shows its typical structure:
you can change the ssid to which access point you want.
If you see following output after you use hostapd command:
this means connect successful.
If you want to connect a access point which has a password you should change the wpa_supplicant configuration like this:
the psk is the password proto and key_mgmt is the encryption options.
FAQ
when you see this output you can use: sudo rfkill unblock wifi
when you see this output that means you may run another wpa_supplicant, you should close it then you can run another wpa_supplicant if you don’t know where is it, you can use command: sudo killall wpa_supplicant to kill all wpa_supplicant.
