All models of Deco
It's been reported that the Deco may lose Internet connection frequently under Spectrum network. The main Deco may turn red, rebooting the Deco or unplugging/plugging the Ethernet cable from the modem could restore the connection.
However, if the connection doesn't recover by power cycling the Deco, unless power cycling the Spectrum modem, you're strongly suggested to contact Spectrum to troubleshoot first. On some occasions, the "Online" LED on the Spectrum modem always remains illuminated, while you're actually get disconnected from their network.
It's also suggested to verify the IP address on the Deco network (Open the Deco App > More > Advanced > IPv4) when the issue happens. If the IPv4 address is all 0.0.0.0, the disconnection might be also caused by the line or modem, try to contact Spectrum for further assistance.
If Spectrum confirms there is nothing wrong on their end or with the modem, please continue to read on.
If the internet access could be easily restored by power cycling the Deco or Spectrum has confirmed the internet connection is all good from their end, please install the following beta firmware accordingly on the Deco and check whether the issue could be solved.
Download link for the beta firmware:
Note: Please check the device label to verify the hardware version of your device first, and choose the correct file to download and install.
For the unstable connection with other ISPs, the beta firmware is also worth a try if the ISP internet or modem is confirmed to be good and stable.
