Introduction:
An Asus router blinking blue light can be frustrating for homeowners and small business owners using an Asus router. This article discusses what causes an Asus router flashing blue light and provides simple steps to troubleshoot the issue. The topics covered include common issues behind a blinking blue light, troubleshooting techniques, router model comparisons, and frequently asked questions.
Causes of Blinking Blue?
There can be several potential reasons for the blue light on an Asus router to blink intermittently instead of remaining solidly lit:
Loose Cable Connection
A loose or faulty Ethernet cable connecting the router to the internet modem is a common cause. The blinking blue light indicates the router is not receiving a stable internet connection.
DNS Resolution Problems
If the router faces issues resolving domain names, the blue light may blink as it tries to connect to the internet. Incorrect DNS server settings can result in such behavior.
Hardware Issues
Extended usage may degrade router hardware over time. For aging Asus routers, a blinking blue light could signal impending hardware failure.
Firmware Problems
Outdated or corrupted firmware is another possibility. A router firmware update may fix underlying bugs affecting the blue light.
Wireless Interference
Nearby devices like cordless phones or other WiFi networks can interfere with the wireless signals of an Asus router blue light blinking.
Router Reset Needed
Periodic resets help refresh the router by clearing caches. Intermittent issues may resolve by power cycling the Asus blinking blue light.
Troubleshooting Asus Router
Basic troubleshooting techniques can assist in diagnosing the root cause behind an Asus flashing blue light:
Check Cable Connections
Ensure all Ethernet cables connecting the modem and router are firmly plugged in without any looseness or breakages.
Restart Network Devices
Power cycle the router and modem by unplugging them for one minute before reconnecting. Also restart other connected devices.
Check For Firmware Updates
Log in to the router’s administrative page to verify if any new firmware upgrades are available to address issues with the Asus router blinking blue light.
Reset Router To Factory Defaults
Use the tiny reset button, usually located at the rear or bottom, to wipe out custom settings and reload factory configurations.
Isolate Router From Interference
Temporarily disable other nearby WiFi networks or move the Asus router flashing blue light away from potential interference sources.
Modify Wireless Settings
Try adjusting wireless channel, encryption mode or transmit power levels through the router’s web interface.
Contact ISP If Needed
Contact the internet service provider to confirm no outage or connection problem exists at their end for the Asus zenwifi blinking blue.
Model-Specific Troubleshooting
While the root causes and generic steps remain similar, exact procedures may differ by Asus router model:
Asus RT-AC86U:
Reset button at rear, hold 10 seconds. Firmware update from System > Firmware Upgrade page.
Asus RT-AX88U:
Reset button at bottom panel, press 30 seconds. Firmware upgrade from Advanced Settings > Firmware Upgrade page.
Always consult specific router’s manual for any model-based troubleshooting variations to resolve Asus zenwifi flashing blue issues.
Comparing router models troubleshooting steps
While blinking blue light issues on all models of Asus routers have similar causes, troubleshooting steps may vary slightly depending on router model. Let’s compare steps for two popular router models:
| Router Model | Factory Reset Method | Firmware Update Method |
|---|---|---|
| Asus RT-AC86U | Hold reset button at back for 10 seconds until blue light blinks twice | Log in to router admin page and click System then Firmware Upgrade |
| Asus RT-AX88U | Press and hold reset button for 30 seconds at bottom panel | Log in and navigate to Advanced Settings > Firmware Upgrade |
As seen in table above, reset button locations and firmware update pages may be different for different models. Always refer router’s user manual for model specific troubleshooting steps if issue persists.
FAQs
Q. What other light signals does Asus router show?
A: Asus routers typically have LED lights indicating 2.4GHz WiFi signal (orange), 5GHz WiFi signal (green) and internet connectivity (blue light discussed in article). Colour and blinking patterns of each light indicate signal strength and connection status.
Q. How long should I wait after a router reset?
A: It’s recommended to wait for at least 2-3 minutes after a factory reset or power cycling the router before powering it back on. This allows sufficient time for settings and cache to clear out completely.
Q. My router reset did not help, what next?
A: If resetting the router does not resolve the blue light issue, next steps would be to update firmware, check for any hardware issues, inspect cables and ports closely, and contact internet provider or Asus support for troubleshooting.
Q: Can a loose cable cause constant blinking?
A: Yes, a loose or faulty Ethernet cable connected to the WAN port of router can certainly cause the internet blue light to blink continuously instead of staying solidly lit. Tightening or replacing the cable should fix it.
Conclusion
By understanding the root causes and following basic troubleshooting best practices, issues resulting in an Asus zenwifi solid blue light condition can often be solved without needing technical assistance. These include checking connections, restarting devices, applying firmware and settings updates, and eliminating potential interference sources. Regular maintenance like periodic resets also helps keep the Asus router functioning optimally.
