Over the weekend, our team identified a recurring issue affecting DrayTek routers— including models we’ve previously supplied and installed. If your business relies on uninterrupted connectivity, this issue could be impacting you.
Why are some DrayTek routers crashing?
Some DrayTek routers are experiencing crashes under load, leading to:
• Devices dropping off the network
• No internet connection
• Slow or unresponsive systems
In many cases, this isn’t due to a fault with your internet connection but rather the router itself. Even though the device appears powered on, key services like DHCP and routing stop working, effectively taking down your network.
How can I stop my DrayTek router from crashing in this way?
Through our investigations, we’ve found several steps that may help mitigate the issue:
• Disabling SSL VPN can reduce the frequency of crashes.
• Disabling the DSL/WAN1 connection may stabilize the router long enough to perform necessary updates.
• Using mobile tethering can provide a safer method for upgrading firmware.
⚠ Important: Do not attempt a firmware update if your router is unstable. This could render it unusable (“bricked”).
Why is this important?
This issue highlights the importance of:
• Regular firmware updates— but only when applied safely.
• Active monitoring to detect potential failures before they disrupt your business.
• Ongoing security updates— DrayTek is expected to release a permanent fix, which will require another update.
How Our Managed Service Protects You
If your router is part of our Managed Firewall/Router Service, you’re already covered with:
