Why should you troubleshoot
your router?

Routers are the gateway to the internet for every company. Especially if the routers are not designed to be redundant, failures can quickly lead to major problems. Therefore, it is very important to pay attention to your routers to be able to solve problems quickly in case of failures.




3 areas where
error-free routers
are essential



If you run your servers over a cloud provider, it is important that the routers are working properly so that access is guaranteed. If the connection to the internet is interrupted, access is impossible.




Companies with distributed locations often use VPN connections to enable secure communication. The VPN tunnel is typically established through routers. If this is not possible, a location is no longer accessible.


Web access

Web access

Many servers, for example SharePoint, Exchange, or even your web shop, which are all hosted in your own data center, must be accessible from outside. If they are not accessible due to a problem with your routers, this can quickly lead to financial loss and to frustrated customers.

3 steps to troubleshoot your router

Step 1

Step 1: Router monitoring

By monitoring your routers, you will always have an overview of the router's components such as CPU, RAM, or temperature and you can take countermeasures to prevent failures in case of critical values. PRTG provides the perfect solution to prevent downtime because it offers many sensors for routers from leading manufacturers.


Step 2

Step 2: Router management

If connection problems occur frequently, or if the load on individual components is too high, you should take a look at the configuration. In many cases, this will already solve the problem. Occasionally, routers can also no longer be sufficiently dimensioned due to the growth of the company. In such a case, you should consider a replacement.


Step 3

Step 3: Router troubleshooting

Remember to always keep an eye on the firmware. Especially upgrades that close security gaps should be installed as soon as possible. Unfortunately, problems can also be caused by faulty or outdated firmware. Therefore, regularly check whether updates have been provided by the manufacturer. For this purpose, PRTG also provides a sensor that displays the current firmware version.
