Some network hardware including routers, modems, APs and switches can have adverse reactions to vulnerability scanning. This is rare and often indicates an issue, as the Nodeware scan policy avoids DoS and other harmful plugins, this means even a basic scan by an attacker could interrupt the flow of network traffic.
The fastest solution is to Exclude the affected devices in the Nodeware dashboard. For more information about excluding devices, see the Excluding Devices knowledge base article in the Nodeware Dashboard section.
This is only a temporary work-around, as this will limit your visibility into current vulnerabilities on the device.
The long-term resolution is to update your device with the latest firmware and software patches. If there are none available, we recommend contacting the hardware vendor to report the issue.
If the device affected has passed EoL (End of Life), you should strongly consider upgrading your equipment as this often means not only are there potential issues, but it will not continue to receive critical security patches.
