How to connect to the Q1 Pro using the same IP, no matter whether it’s connected via Wi-Fi or Ethernet.
These instructions (but not the article text) have been generated via ChatGPT and then tested on a Q1 Pro running FreeDi (Armbian bookworm). They are published here for easier retrival via links in discussion forums and indexing by search engines.
The Qidi Q1 Pro provides Ethernet and Wi-Fi, which normally results in two different IPs depending on the connection used. This is not practical when setting up the slicer or home automation solutions.
It’s however possible to force only one interface to be used at the same time, while giving priority to cabled Ethernet for maximum speed. This is obtained by using NetworkManager.
In the main network router (in my case OpenWRT) I will assign the same IP to both MAC addresses, which otherwise it would not be safe due to ARP conflicts and potential network instability.
Keep in mind that other routers might not even allow multiple MAC addresses for a single IP. These instructions were tested on OpenWRT 25.12-rc.
Armbian bookwork uses NetworkManager, confirm it as active by running:
systemctl is-active NetworkManagerStep 1 — Set Ethernet as primary
Run:
nmcli connection showYou’ll see something like:
Wired connection 1YourWifiName
Adjust commands below accordingly.
Step 2 — Set priorities
nmcli connection modify "Wired connection 1" connection.autoconnect-priority 100
nmcli connection modify "YourWifiName" connection.autoconnect-priority 0Higher number = higher priority.
Step 3 — Tell Wi-Fi not to autoconnect if Ethernet is active
nmcli connection modify "YourWifiName" connection.autoconnect-retries 0
nmcli connection modify "YourWifiName" ipv4.never-default yesReboot.
After reboot with both connected you can try multiple commands to verify the operational status:
ip route
ip link show
ip route get 8.8.8.8
nmcli device statusIt shows only one default via and it will use end1 if available, or the Wi-Fi interface if the Ethernet cable is disconnected.
Since the Wi-Fi is always connected, the switchover is basically instantaneous.
