What Lights Should be on my Cox Modem?
Just the positions of lights on the Cox modem can often help you determine if you are getting your Internet service provider's connection right or not. Cox modem lights are special indicators on the device that can tell you about the status of the modem and its connectivity to the internet, so knowing what each light means can come in handy when fixing some problems without having to call the service. Below is a breakdown of which lights should be on for a functioning c ox modem:
Power Light
The power light is perhaps the most fundamental status that can help you know whether your Cox modem is receiving power. This light should always be green and on solid when the modem is connected to the power source and switched on. If the power light is out, then try turning off the power and replugging the power cord to fix connection issues. If it is not on, check whether the outlet is functional by connecting another device. If other devices work in the outlet, but the modem power light remains off, then you have a problem with the modem and may require to replace it.
Downstream Light
The light on the bottom right of the modem shows that your modem is now actively connected to the Cox network and is receiving data from it. On most Cox modems, this will be labeled simply as ‘receive’ or the downward pointing arrow is used to represent the downstream bandwidth. So such downstream indication should be always a firm green color when the modem is switched on provided that modem cable connections are properly made. If it’s blinking instead of steady, check the fiber optic wire connected to the modem by unplugging and plugging it back in.
Upstream Light
Just like the downstream or ‘receive’ light, the upstream or ‘send’ light means your modem is transmitting back to the Cox network. This secure upload connection should also remain solid green at all times if coaxial cables and ethernet cables are correctly connected in an active Cox internet plan. If the upstream light is missing on the modem then it could be a wiring or cable connectivity issue that is not allowing the modem to send data.
Ethernet Light
If you have one of the LAN/Ethernet ports of the Cox modem connected through an ethernet cable with a particular device, then that corresponding ethernet light should be glowing green. Most of the modems developed will have more than one Ethernet port with the commonest being four; therefore ensure that the port through which the computer, router, or the specific device you want to connect to the modem is connected has a link light. If this LED light is off, it’s advised to connect to another LAN port and if that does not work, the ethernet might be a bad wire.
WiFi Light
If your Cox modem is also a wireless router with the functionality of a cable modem, then there should be a light showing that it is broadcasting a WiFi signal. This wireless light is usually indicated as ‘WiFi’ or else has a sign like the one below Radio waves. This light should remain solid for the connectivity of the wireless devices. Should WiFi clients be experiencing connection problems or they are experiencing slow WiFi but this light is off, then it means that there is a WiFi router in the modem hardware that needs to be rebooted.
Internet Light
Almost all modems that Cox offers have a single LED called ‘Internet’ or a globe icon that should glow continuously in green regardless of the time of day if your modem is connected to Cox and you have an Internet connection through it. Consider this as the master status light: be it through Ethernet or Wi-Fi, if this highest level Internet light is steady on, devices should be able to get on the Internet. If the whole light is off or flashing while other link lights are steady, then there is a problem with provisioning with the modem and Cox.
Activity Lights
Besides the above indicator status lights, most of the new Cox modem hardware has other activity lights that would blink periodically to indicate data transmitted or received through the cable or ethernet. It’s even common for these quicker flashing lights to blink on and off erratically even if your modem is properly connected. If all activity lights are off, although devices are connected, you may not be properly forwarding traffic. It is good to see these activity indicators flashing – a black modem connotes greater problems.
Putting It All Together
As long as all the modem lights are coordinated correctly with the equipment and cables connected and there is blinking which shows that the data is on the move – yet the main master light of the net connection is not blinking, this suggests that the Cox modem is indeed online and working. The only time it means there is no internet connectivity is when there is no status light blinking and the activity lights flicker; if there are other lights on besides the ALL status lights being on steady, then there is a physical connectivity problem or internet provisioning issue.
So in summary, these are the key lights needed to have your Cox modem working properly:
- The project that will best suit the identified target market and has the potential of yielding a high return on investment is referred to as Solid Green Power Light.
- This is the Solid Green Downstream or the Receive light, which is used to signal the end of the call.
- From a perception constellations view, the firm should establish Solid Green Upstream (SEND) Light.
- The Ethernet Light(s) for ports with active LAN ports shall be green in color.
- Dual-Moded Light for Solid Green WiFi (combo modem/router gateways)
- Solid Green Internet Master Light
- Flashing Activity Indicators
As long as those for which required status lights match the Cox-provided equipment connections and plan activation, you should have a functioning modem bringing the internet to your connected devices. If ANY of those critical lights are different from the description above, begin the process of working on that specific element; modem power and cables or the access point configuration from your ISP. Being on the phone with customer service is always a laborious experience, but being able to use these modem lights to diagnose where the problem lies helps get back on the Internet ASAP.
