Internet Light

The internet light shows the status of the internet/WAN connection.

Solid light: The router has an active internet connection.

Flashing light: The connection is intermittent or weak. This could be an ISP issue or cabling problem.

No light: There is no internet connectivity. Verify the modem and ISP connection.

Orange/Yellow light: A flashing orange or yellow indicates no working internet connection on some models.

Ethernet Lights

Ethernet port lights display the status of devices connected to the local network.

Solid light: An active, wired device is linked up to that ethernet port.

Flashing light: Data is being transferred over that port.

No light: No device is currently connected to that ethernet port.

WiFi Light

The WiFi light turns on when the router’s wireless network is broadcasting.

Solid light: WiFi is enabled and operating normally.

Flashing light: The wireless signal is intermittent or connecting.

No light: Wireless functionality is likely turned off.

WPS Light

The WPS light is activated when connecting devices using WiFi Protected Setup.

Solid/Flashing light: WPS mode is active to allow new devices to connect.

No light: WPS pairing mode is off.

Note: Some router models also feature additional lights for USB ports, VoIP/phone connections, VPN status, and more. Refer to your device’s user manual for specifics.

eSATA and USB Lights

The light shows if the eSATA drive or USB device is connected to the router. A solid white light means the connection is active and successful.

Understanding Linksys Router Light Patterns

Now that you know the basic indicator lights, let’s go over what different patterns and colors signify when troubleshooting your Linksys router:

Solid Light

A solid LED light indicates normal operation of that router function. If the WiFi light is solid, for example, the wireless network is up and working properly.

Flashing Light

A blinking or flashing LED means there may be an issue with that aspect of the router. Common causes include weak signal, intermittent connectivity, missing configuration, firmware errors, etc.

Light Off

If an indicator light is turned off, it usually means that feature is disabled or inactive. For example, no ethernet light when connected means the port is disabled or the cable/device itself has a problem.

Red Light

While not all models use this, a red LED light on Linksys routers generally signals a problem. Check if other lights are off that shouldn’t be, try restarting the router, reseating cables, resetting to factory settings.

Orange/Yellow Light

Similar to red, an orange or yellow blinking light typically indicates an error or connectivity problem with the router component it represents.

Blue Light

A blue LED light usually means a normal state on Linksys routers. For example, solid blue for the power, internet or WiFi lights. If a light is flashing blue, that can signal activity in a specific area like WiFi pairing.

Green Light

Much like blue, green LED lights signify normal operation on Linksys routers as well. So if your power, ports or WiFi have a solid green light, those functions should be working fine. Flashing green indicates activity.

Purple Light

A purple LED indicates errors with router configuration or setup. You can try resetting the router to see if it clears. Notably, solid purple sometimes means the hardware is in an initial provisioning state.

All Lights Blinking/Flashing

If all the Linksys router lights seem to be blinking or flashing randomly, this typically points to a firmware failure. Attempt restarting or resetting the device, reflashing stock firmware, or lastly replacing the unit if it cannot recover functionality.

Note: Specific light colors and meanings can vary across Linksys router models. Refer to your device manual or the Cisco/Linksys support site for precise indicator details.

Common Linksys Router Issues Based on Light Status

Here are the most frequent problems that cause Linksys router LED lights to behave abnormally:

No Power Light

If there is no LED power light at all, the device is not getting electrical power. Troubleshooting tips:

• Check power cable connections at both ends
• Try a different power outlet in the room
• Use a verified working cable and outlet
• Inspect outlet for voltage and router port for damage
• Attempt router reset and recovery options
• Faulty power supply may require router replacement

Red Power Light

A steadily red power light instead of solid blue/green can mean insufficient power. Things to check:

• Confirm rated voltage matches power supply
• Try alternate power source like UPS battery backup
• Overheating can trigger red light on some models
• Failing power system may need router substitution

Flashing Power Light

A blinking power LED normally signals the router booting up after being turned on or reset. But if it flashes irregularly or persists, possible issues are:

• Corrupt firmware not loading properly
• Inadequate power causing continuous reboots
• Hardware defect requiring repair/swap

Internet Light Off

No internet LED light means there is no WAN connectivity reaching the router. Some troubleshooting tips:

• Recheck cabling from ISP modem to WAN port
• Verify ISP service status for outages in the area
• Toggle modem and router power off/on sequence
• Inspect cables for damage, try replacements
• Check if connected modem has valid internet signs
• Test with different router temporarily if persistent
• Ethernet WAN models require proper IP and gateway

Flashing Internet Light

An intermittent flashing internet light usually signifies dropped or unstable WAN connectivity preventing consistent access. Things to test in this scenario:

• Examine cabling for any damage, bent pins, etc
• Relocate router closer to modem if signal weak
• Confirm internet subscription is active, no service issues
• Try replacing ethernet cables one by one
• Set both modem and router to Auto Negotiation for speed/duplex
• Check for firmware updates and upgrade as necessary
• Consider installing custom firmware if unsupported

Note: An orange or amber colored internet LED also indicates connectivity problems on many Linksys routers. Treat as you would a flashing LED situation.

Ethernet Port Light Off

If your router has ethernet LEDs per wired port, no light means there is no device connected or recognized on that interface. Try the following fixes:

• Inspect ethernet cabling for damage or pin issues
• Verify device has power – attempt different cable
• Check if ethernet port enabled and not disabled
• Test port with a laptop or device known to be working
• Scan router admin interface for configured device listing
• Toggle port power off/on along with router reboot

Flashing Ethernet Port Light

A flashing or blinking ethernet port LED reflects data activity going to a connected device. This is normal operation. However, if flashing persists with nothing hooked up, it may imply:

• Faulty port transmitting invalid data
• Port stuck thinking device still linked
• Potential router firmware corruption issue

WiFi Light Off

No WiFi LED when expected means the router’s wireless network is down for some reason. Steps to revive connectivity:

• Log into router to confirm wireless enabled
• Check WiFi controls like scheduling/timers
• Review wireless settings for errors like invalid SSID
• Perform router reboot and reconfigure wireless
• Inspect router antenna connectors if removable

A purple LED light on a Linksys router typically indicates configuration problems or failures during initial setup states. Attempting router recovery procedures like these can help resolve:

• Factory reset router to wipe settings
• Refresh stock or custom firmware
• If new install, rerun setup procedure
• Remove and reinsert both power and cables
• Test with secondary compatible router

Note: On some Linksys gear like Velop mesh systems, solid purple means ready for app setup. Flashing purple shows firmware upgrade in progress.

All Lights Flashing Randomly

If all the various LEDs on your Linksys router seem to be blinking randomly with multiple color changes, this likely points to corrupt or crashed firmware bringing down functionality. Recovering with the following process should clear the issue:

1. Hold reset button 30+ seconds to force hardware defaults
2. Unplug and discharge electricity for a minute
3. Connect to router directly via ethernet if possible
4. Flash official Linksys firmware from online database
5. Reconfigure wireless settings and security password
6. If problem returns, replace router hardware

Pro Tip: Severe lightning storms are a top cause of router firmware disruption leading to blinking LED syndromes.
