ARROW Manager Network Settings
Overview
Section titled “Overview”When a device is on a client’s network and something is not connecting, ARROW Manager is where you find out why. Its network view runs right on the device and shows you, in real time, what each interface is doing: whether ethernet has internet, whether cellular failover has kicked in, and whether the VPN tunnel is up. It also lets you update and restart the Network Manager service that keeps all of that working.
Reading Network Status
Section titled “Reading Network Status”The dashboard shows live status for every interface, so you can tell at a glance where connectivity stands.
| Interface | Icon | What it covers |
|---|---|---|
| Internet | Globe | Overall internet reachability |
| Ethernet | Network | The wired connection (the vmbr0 bridge) |
| Cellular | Signal | The LTE modem connection (wwan0) |
| VPN | Shield | The NetBird VPN tunnel |
Each one carries a status badge and a dot, which together tell you the state:
| Indicator | Meaning |
|---|---|
| Green dot | Connected and active |
| Connected badge | Interface is up with connectivity |
| Disconnected badge | Interface is down or has no connectivity |
| Disabled badge | Interface is intentionally disabled |
Hover over any status to dig into the detail. Ethernet, cellular, and VPN show their internal IP; internet, ethernet, and cellular show the public IP. Cellular carries the most: signal strength in dBm, carrier, band, latency, and the advanced SINR, RSRP, and RSRQ metrics that matter when you are chasing down a weak connection.
Managing the Network Manager Service
Section titled “Managing the Network Manager Service”Network Manager is the service that handles connectivity and configuration on the device. From ARROW Manager you can check its version, upgrade it, force a clean reinstall, and restart it. Open the Network Manager section on the device to see the current status and your options.
The status panel tells you the current version installed, the target version available, when it was last checked, and a badge reading either “Up to Date” or “Upgrade Available”.
Check for updates. Click Refresh to compare the installed files against the target and see whether a newer version exists.
Upgrade. When one is available, click Upgrade, confirm, and wait. The service restarts on its own, which may briefly interrupt connectivity.
Force Upgrade. This reinstalls the Network Manager files regardless of the version check. Use it when a normal upgrade will not take, files look corrupted, or you just need to reset the configuration.
Restart Service. This restarts Network Manager without upgrading. Reach for it when connectivity acts up, after a manual configuration change, or when the service stops responding.
Version Details and File Hashes
Section titled “Version Details and File Hashes”Expand File Hash Comparison for a closer look at what is installed. It breaks out the script file (the main Network Manager script) and the service file (the systemd unit), and for each it shows the current hash, the target hash, and whether it is up to date or needs an update.
The reason it compares hashes rather than just version numbers is that a file can drift or get corrupted without the version changing. Comparing hashes catches those cases and tells you an upgrade is needed anyway.
The Interfaces, Briefly
Section titled “The Interfaces, Briefly”Ethernet (vmbr0) is the primary interface, a Proxmox bridge that carries wired connectivity, gives your virtual machines network access, and serves as the main internet route when it is available.
Cellular (wwan0) is the LTE modem for backup. It takes over when ethernet loses internet, providing failover, and it also backs the advanced LTE Bridge Mode feature. See Cellular Management for the details.
VPN (wt0) is the NetBird interface. It builds the secure tunnels into your VPN network that let you reach the device remotely, and the NetBird service manages it automatically. See VPN Management for connection details.
When You Would Use This
Section titled “When You Would Use This”Check network status right after a physical install, after any network change at the site, or when you land somewhere new and want to see how the cellular signal looks. If connectivity goes sideways, restarting the Network Manager service is usually the first thing to try, and the file hashes are worth a look if behavior seems off. Force Upgrade is your fallback when a normal upgrade will not go through. For upkeep, check for Network Manager updates now and then, upgrade when a new version lands, and review network status after any power event.
Troubleshooting
Section titled “Troubleshooting”No internet is shown. Check the physical ethernet cable, verify the network configuration at the site, restart the Network Manager service, and confirm cellular failover is available as a backup.
Cellular will not connect. Check the signal strength, confirm the SIM status, and make sure cellular is not disabled. Cellular Management covers this in more depth.
VPN shows disconnected. Confirm there is internet connectivity first, then check the NetBird service status and the VPN configuration. See VPN Management for troubleshooting.
A Network Manager upgrade fails. Try Force Upgrade, restart the service manually, and check that the device has enough disk space. Contact support if it persists.
