2. Power Cycle Spectrum Equipment
This is a universal troubleshooting step for any gadget. Based on the feedback I've received, power cycling helped around 50% of the users solve the blue blinking light.
Just like other electronics, Spectrum internet equipment can also face random glitches even when used for normal tasks. The easiest way to fix this is to power cycle your networking devices. Power cycling means disconnecting all the devices and putting them on a short break.
- Switch off the Spectrum router.
- Unplug the Router from the power supply and other connections.
- Wait a few minutes, and reconnect all the cables to see the solid blue.
- By now, your issue will be resolved. If not, opt for the following solutions.
3. Check for Internet Outage
Sometimes, the internet issue comes from the service provider's end. In most cases, they inform you beforehand, but chances are you may face a sudden downtime. It could be because of the government's order or Spectrum's systems under maintenance.
- Look for official information on outages and troubleshoot Spectrum Internet.
- If service is under maintenance or an internet outage is in place, wait until it's restored.
- However, there is no issue from their end, you can reset the Spectrum router.
4. Test a Wired Connection
If there's no service outage, you must ensure the router communicates with the ISP by testing it with a wired connection. This determines if the entire device has become faulty or just the Wi-Fi part. Here's how to go about it:
- Attach one end of the Ethernet cable to the modem and the other end to the laptop or PC's ethernet port.
- Open a web browser and visit any website. If you can access it, your internet is working fine.
- If it doesn’t, it means something is wrong with your router's Wi-Fi function. You must reset or replace it.
5. Limit Connections on the Network
Your Spectrum router might have been overloaded with many devices on the network. As a result, the router heats up and leaves you with slow internet. So, disconnect unwanted devices to overcome bandwidth overload and get over the Spectrum internet not working.
6. Reset Spectrum Modem & Router
If nothing above worked, now is the time to factory reset the Spectrum router. Resetting your router will change all its settings to default. And you have two ways to reset your device. One being soft reset and the other being hard reset.
Soft Reset Router (Using My Spectrum App):
- Download and open the ‘My Spectrum' App on your phone.
- Login to your account.
- Click on the ‘Services' tab.
- Under the Services tab, open ‘Services & Equipment'.
- Select your Gateway and tap on “Experiencing Issues?”.
- Finally, tap on ‘Reset Equipment' and let it complete the process.
Hard Reset Router (Manually Using Pinhole):
- Find a Reset button on the router's back. (Check the above picture for reference)
- Take a pin and hard press the button.
- Wait till the device boots up again (don't interfere)
- Once done, the flashing white (or blue) light may disappear.
7. Update Router Firmware
An outdated firmware might contain some bugs, usually fixed with updates. Although most routers update their firmware automatically, the option might be disabled by default. So, it makes sense to update your router firmware manually.
Steps To Update Router Firmware:
- Log in to the Admin Portal.
- Now, go to the System settings section.
- Check if there is any update available.
- If you find any, download and install the firmware.
- Ensure the Auto-Update option is turned on.
8. Change the Router’s Location
In case your router is getting heated up too soon, you need to change its location to a cooler place. Overheating is generally caused by too many devices connected to the network. Also, avoid keeping the router in a closed space or near direct sunlight.

9. Upgrade your Spectrum Equipment
Lastly, when all is said and done, and nothing works, now is the time to replace your internet equipment. Contact Spectrum and request a gateway replacement.
Alternatively, you can also buy better equipment and save on monthly equipment rental. For instance, Spectrum provides a mediocre modem for free, but getting a third-party modem for Spectrum can help you achieve better performance.
That said, Spectrum charges $5/month to make the connection wireless, you can avoid paying the equipment rental and even get better performance by buying your own router or mesh WiFi.
