How to Fix Spectrum WiFi Not Working (1)

Glitched Launch Configurations

The launch configurations contain the IP configurations and the bandwidth instructions. It is possible that the router’s startup configurations may have been corrupted following the power outage or as a result of power surges, and the router will receive an error because it cannot communicate with its server.

Deterioration of the Cable

If the router’s principal source of the network is interrupted, such as via a broken cable, a WiFi connection cannot be made. The main cable running to your house from the outside may have deteriorated due to exposure to the elements or other environmental factors. Therefore, double-check the cable’s condition outside.

Disruption of Service

Internet service providers occasionally suspend service for brief periods to perform maintenance, such as addressing server-related issues or installing new software. Because of this, the entire server network must be turned off. This causes service disruptions, which can linger for several hours.

Connection Problems

Unplugged or improperly plugged-in routers are a common cause of connectivity issues. So always double-check the wires to ensure they’re not plugged in incorrectly.

Here are the steps for how to do that –

  • Connect the black internet wire to the modem’s blue input port.
  • Connect the RJ45 cable to one end of your router and the other end of your computer’s LAN port.
  • Verify that your computer is connected to the network.
  • Take note that the greenish-blue input, usually designated OPT is where you should plug in an optical cable.

If you still can’t get online via a wired connection, it’s safe to assume that your router isn’t receiving a proper internet connection.

Also, ensure the modem’s “globe light” is on before calling your internet service provider to help you.

Reset Network Domain Name System

If you have successfully established a wireless connection with Spectrum but still cannot receive any data, you may need to flush your DNS, as DNS files could become outdated, corrupted, or broken, leading to WiFi problems.

  • Connect to Spectrum WiFi network connection to your device.
  • Launch CMD on a Windows machine or Terminal on an Apple computer.
  • Perform a DNS flush by entering the following commands –
    • Enter “ipconfig /flushdns” into the Windows command prompt and press Enter to reset the DNS servers.
    • In the Terminal app on macOS, enter “sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder,” and then press Enter.

After that, restart your device, and you will be able to access the Spectrum WiFi network.

  • Remove the power cord and wait another 30 seconds.
  • After that, press and hold the reset button for another 30 seconds while the power adapter is plugged in.
