When an industrial network is small, manually configuring routers is usually manageable.
An engineer can set the APN, LAN address, VPN parameters, and test the connection on one router without much trouble. But when a deployment grows from 5 routers to 50 or 100 across different factories, equipment rooms, or remote sites, the real challenge is no longer knowing how to configure a router.
The problem is keeping every router configured consistently.
One engineer may adjust a firewall rule. Another may forget to enable a backup connection. A third router may still be using an older VPN configuration.
The network may continue to operate, but months later, when another engineer takes over maintenance, troubleshooting becomes much harder.
That is why industrial network automation should not start with the goal of automating everything.
A better starting point is identifying tasks that arerepetitive, rule-based, and should not depend on an individual engineer’s memory or experience.
Bulk deployment is one of the clearest areas where automation provides immediate value.
For example, a machine builder may need to deploy an industrial wireless router at dozens of remote sites. Each router could require settings such as:
Within the same project, most of these settings may be identical. Only a few parameters, such as the device name, IP address, SIM card, or site ID, may change.
In this situation, asking an engineer to open the web interface of every router and repeat the same configuration is inefficient and increases the risk of inconsistency.
A better approach is to create a standard configuration and manage site-specific parameters separately.
The principle is simple:
Define common settings once, and manage only the variables that change from site to site.
When a new site is added, engineers only need to configure the site-specific information instead of rebuilding the entire router configuration from scratch.
WAN failover is another task that should usually be automated.
Consider a factory that uses wired broadband as its primary connection and 4G or 5G as backup.
If the wired WAN fails and someone must first notice the outage, log in to the router, and manually switch to cellular connectivity, the backup connection provides limited protection.
A better design is to define the failover logic in advance:
Which connection is primary?
Which connection is backup?
How should the router determine that the primary link has failed?
Should it automatically return to the primary connection once the network recovers?
Routers such as the USR-G806w support automatic failover between wired WAN, cellular, and Wi-Fi WAN connections. The USR-G816 also supports WAN failover and dual-SIM backup.
For unmanned or remotely located industrial sites, this type of logic should normally be handled automatically by the router rather than by an operator.
Engineers should not need to log in every morning simply to check whether each router is still online.
What should be automated is the process of detecting abnormal conditions.
For example, a management platform can identify situations such as:
The USR-G816 supports remote monitoring and alerts for conditions including device disconnection, weak signal, and traffic usage thresholds.
The USR-G806w also supports remote monitoring and alarm notification mechanisms.
This changes the maintenance workflow from:
“Check every router to see whether something is wrong.”
to:
“Focus only on routers where an abnormal condition has already been detected.”
For networks with dozens or hundreds of remote sites, this can significantly reduce repetitive maintenance work.
Manufacturers often use VPN connections to remotely access PLCs, HMIs, industrial PCs, and other field equipment.
The challenge is that VPN configurations often contain multiple parameters, including server addresses, authentication settings, routing rules, and access policies.
If engineers rebuild these settings manually for every project, configuration differences can easily appear.
A more scalable approach is to divide VPN settings into two categories:
Standard settings and site-specific variables.
For example, VPN type and basic security policies can be standardized, while site IP addresses, authentication information, and routing parameters can be managed separately.
Both the USR-G806w and USR-G816 support multiple VPN technologies.
When planning a large industrial wireless router deployment, VPN configuration should therefore be treated as part of the overall standard deployment process rather than as a separate manual task for every device.
Routine maintenance tasks can also benefit from automation.
Examples include:
The USR-G806w supports remote device management, including configuration, restart, firmware management, and scheduled tasks.
However, there should be a clear boundary.
Just because a task can be automated does not mean it should be executed automatically across every router at the same time.
High-impact operations such as firmware upgrades, major firewall changes, or modifications to critical VPN parameters should usually follow a controlled process:
Test first.
Deploy to a small group of routers.
Verify the result.
Then expand the change to the remaining devices.
Automation should reduce repetitive work without removing necessary operational control.
A practical rule is:
Automate tasks that are frequent, repetitive, and governed by clear rules. Keep human approval for tasks that are infrequent, high-impact, or highly site-specific.
Settings such as APN parameters, basic network configuration, alerts, WAN failover, and standard VPN settings are good candidates for automation.
Changes involving production network architecture, core routing policies, or large-scale security modifications should generally be tested and introduced gradually.
The purpose of automation is not to remove engineers from the process.
It is to stop engineers from repeatedly performing the same predictable tasks.
In one remote networking application described for the USR-G806w, centralized networking was used to connect CNC equipment distributed across 23 production sites.
The key point is not simply that remote configuration becomes faster.
As the number of sites increases, centralized and standardized management becomes much easier to scale than maintaining every router individually.
If you are planning to deploy dozens of industrial wireless routers, there is no need to begin with a complicated automation system.
Start by dividing your router configuration into three groups:
Settings that are the same on every router.
Settings that vary by site.
Actions that should occur automatically when a network problem happens.
Turn the first group into a standard configuration.
Manage the second group as site-specific variables.
Convert the third group into automated alerts and failover rules.
Once these three areas are clearly defined, adding more routers or remote sites becomes much easier.
More importantly, the network no longer depends heavily on the experience or memory of one particular engineer.
For industrial network deployment, that is where automation delivers its most practical value.
