Are you a Spectrum internet user renting internet equipment from the service provider? Ever wondered what those Spectrum modem lights mean? While an internet plan and the supplied equipment can be excellent, knowing about the status lights on the Spectrum modem can help you identify connectivity-related issues (if any) at the earliest.
In the subsequent sections, I shall touch upon the Spectrum internet modem lights and the respective states associated with each, just to acquaint you with the nature of indications. Once you know what each LED means across states, you can quickly figure out the possible cause, troubleshoot the same, or report to the ISP to get it fixed.

Spectrum Modem Lights: Explained
Before moving any further, I would like to state that different Charter modem lights mean different things, depending on whether they hold steady or flash. Also, different modem versions have similar names and meanings. So, irrespective of the model you own, I’ve also included ‘Alternative Names’ to make things easier. With that out of the way, let’s jump right in:
1. Ethernet
Alternative Names: Link, Ethernet, and Act (Can be 1 through 2 or 1 through 4, depending on the number of ports your modem has)
Meaning: As the name suggests, the ethernet light indicator tells what is the LAN connection status of your connections. Using a modem, you would typically establish a LAN connection with the concerned device. This light indicates the health of this connection.
Ideal Light Activity: If the Ethernet light is steady green, the condition is considered ideal.
What if it is not in its ideal position?
If the light is red, amber, or keeps blinking green, the Ethernet connection wouldn’t hold steady. Consequently, there would be no internet to work with. Sometimes, the Ethernet icon might glow white, marking a faulty state. Another issue is the change of Spectrum modem lights from blue to white, which hints at a sudden outage.
Solution
It is better to check for loose connections, broken cables, and even internet outages using the smartphone app that comes with the modem.
2. Upstream
Alternative Names: Send, Cable Modem/Send, US
Meaning: Do you remember anything about the modem streams? 16 x 8, 24 x 8, or even 32 x 8 channel bonding is what talks about upstream and downstream channels, where the lower number determines the upstream prowess of the modem. This modem light tells that internet is active, and data packets are being sent.
Ideal Light Activity: The upstream light or LED should ideally be solid red, which means that multiple channels are connected, and internet upstream/upload speeds are as promised.
What if it is not in its ideal position?
Non-ideal colors include blinking green if the modem tries to connect to the ISP for upstream throughput. If the Spectrum modem lights orange, in this case, it means restricted connection or availability of only one channel.
Solution
Check with the internet service provider. Also, if you have a capped or metered connection, check if you have exceeded the data cap.
3. Downstream
Alternative Names: DS, Receive, Sync, Cable Modem/Receive
Meaning: Head back to the upstream meaning and look for channel segregation, i.e., 24 x 8, 32 x 8, or anything else. The higher number stands for the downstream channels and is analogous to the downloading capabilities offered by your ISP. This light talks about the downloads’ state and tells that the internet is available, and the modem is receiving data packets.
Ideal Light Activity: The light holding steady green is perfect and means multiple channels are available and connected.
What if it is not in its ideal position?
If there is an issue, this light will either show solid amber (restricted access) or blinking green (trying to connect or scanning for channels).
Solution
Check with the internet service provider. Also, if you have a capped or metered connection, check if you have exceeded the data cap.
4. Wi-Fi
Alternative Names: Wireless, WLAN
Meaning: This indicator primarily holds for gateway devices and tells whether the devices are wirelessly connected to the internet or not.
Ideal Light Activity: This light showing solid green means all is well with the wireless connection. For some modem-router combos, even blinking green is a sign of good health.
What if it is not in its ideal position?
If the light is holding steady at red, expect the wireless connection to be troubled. No light means that there is no wireless internet access.
Solution
Gateways usually have both 5GHz and 2.4GHz-specific indicators. Check if the lights are blinking or holding steady. Depending on the type of device, either of these states is acceptable. No light means that there is an issue with the specific band. In that case, you need to reconfigure the device or connect with the ISP.
5. WPS
Alternative Names: Secure, Push N Connect
Meaning: The WPS or wireless protected setup icon tells if the modem/gateway is ready to pair with other wireless devices in the vicinity.
Ideal Light Activity: Depending on the type of modem, the WPS light can be white or blue. Steady light means that the WPS icon is active.
What if it is not in its ideal position?
In case there is no light, WPS is considered unavailable. The blinking light suggests that WPS is scanning the area for devices.
Solution
If the WPS light keeps blinking, check the connection limit of the router and see if the same has been exceeded.
6. Online
Alternative Names: PC
Meaning: This light is akin to the ‘Internet’ icon on most other modems and signifies the state of the internet that your modem is transmitting.
Ideal Light Activity: For most spectrum modems, solid green happens to be a standard reference for ideal light activity.
What if it is not in its ideal position?
If the Spectrum online light blinks blue or white, the modem seems to be searching for an internet connection.
No light or the red light on the Spectrum modem means that the device has failed to try to connect, and there is no internet.
Solution
If the problem persists, try and connect with the ISP or try and power cycle the modem. Spectrum modem lights cycling once after being turned can steady themselves and bring back the inactive internet status to life.
7. MoCA
Alternative Names: N/A
Meaning: MoCA LED indicates that the concerned spectrum internet plan also supplies multimedia to the modem.
Ideal Light Activity: MoCA light blinking shows that the connection is active. The preferred color is green, but some modems/combos can also emanate green.
What if it is not in its ideal position?
If the light is off, MoCA would be as good as disabled. However, amber indicates that the modem is trying to establish a connection, whereas red means a failure.
Solution
For problems, connect with the ISP and see if your MoCA plan has been activated as part of the bundled package.
8. Test
Alternative Names: N/A
Meaning: The test light is meant to test the modem firmware and isn’t available on all devices.
Ideal Light Activity: The ideal light activity for a test LED is no activity.
What if it is not in its ideal position?
If the test light is on, the modem has failed the self-test, and the firmware is not in the best possible condition. The blinking test light indicates an ongoing self-test or any form of software download.
Solution
Wait for the modem to reach a steady state if you see the Test light blinking. If the light is on, either as blue or white, try and contact the ISP.
9. LAN
Alternative Names: Local Area Network (1 through 2 or 1 through 4)
Meaning: While it is similar to the Ethernet icon, different lights and their states for the LAN can give details about the wired speeds.
Ideal Light Activity: Check if the LAN light is green and solid, which signifies a high-speed connection. If the light is blinking green, 100Mbps happens to be the minimum transmission speed.
What if it is not in its ideal position?
Check if the light is turned yellow, which means 10Mbps speeds. Red would mean failed connection, and no light would mean no connection.
Solution
Check for data caps, cable issues, and power outages at the ISP’s end.
10. USB
Alternative Names: N/A
Meaning: Some gateways have USB ports and, therefore, the relevant light. This light means the state of the USB connection.
Ideal Light Activity: If the light is on and solid green, the device is expected to have detected a USB accessory. In case it blinks, the USB is constantly transmitting data.
What if it is not in its ideal position?
No light isn’t suitable if the USB is connected. In case there is nothing plugged in, this seems fine.
Solution
If the USB light is red or anything other than green or blue, consider getting the modem checked.
And while these are some of the more popular lights, you might come across other exclusive LED options relevant to your Spectrum modem. These might include email message light, activity light, Diag light, Coax light, etc. In most cases, steady or blinking green/blue is fine, but yellow or red beckons action.
Spectrum Voice Modem Lights: Explained
In case you have landed yourself a voice modem with spectrum’s bundled internet plan at the help, here are the modem lights that you might come across:
1. Battery
Alternative Names: N/A
Meaning: The battery light tells about the battery condition of your voice modem.
Ideal Light Activity: Consider an active and solid green light as ideal.
What if it is not in its ideal position?
If the light blinks, the battery can be considered faulty or unhealthy.
Solution
If the battery light is off, no external battery is installed. If the blinking, as mentioned above, continues, consider getting the battery checked and connecting the modem to the standard power outlet.
2. Tel
Alternative Names: Voice (1 or 2)
Meaning: This light tells about the quality and state of the voice services, provided you have opted for a compatible plan.
Ideal Light Activity: Check if the light is turned on and holds steady, which signifies active voice access and connected handset.
What if it is not in its ideal position?
If the light blinks, the phone doesn’t seem connected, or the RJ11 cable is not connected ideally.
Solution
Check if the cables are tight and VoIP services are activated.
3. Power
Alternative Names: N/A
Meaning: This indicator talks about the power supply entering the modem.
Ideal Light Activity: Static green is perfect and shows that the modem receives power.
What if it is not in its ideal position?
If you suddenly see red light, check the modem for an overheating or hardware issue.
Solution
Checking the modem or replacing it (verifying the warranty) is the best way forward.
