C6300-V2 wired ethernet connection works but wifi quit working

I get cable signal and internet using wired connection but wifi quit working. Checked all my settings and all is good. Haven't even had this a year yet. I had a previous one, same model and it did the same thing. after about a year the wifi quit working.

    Does the front WiFi LEDs turn OFF when this happens?

     

    What channels are you using? Auto? Try setting manual channel 1, 6 or 11 on 2.4Ghz and 40 to 48 channel on 5Ghz.
    Any Wifi Neighbors near by? If so, how many?

     

    Set 20/40Mhz Coexistence to 40Mhz only. Set CTS to 64. Set Short preamble instead of Long preamble modes. Save settings and reboot the router and satellite(s). Under Advanced Tab/Advanced Settings/Wireless Settings

     

    Be sure to disable any MAC Address randomizers on phones and pads while at home:

    Has a power off for 1 minute then back ON with the ISP modem and router been performed since last update?
    Be sure to restart your network in this sequence:
    Turn off and unplug modem.
    Turn off router and computers.
    Plug in and turn on modem. Wait 2 minutes for it to connect.
    Turn on the router and wait 2 minutes for it to connect.
    Turn on computers and rest of network.

     

    Has a factory reset and setup from scratch been performed?

     

    This C6300 series is of older generation and maybe no longer supported. You might consider getting into a separate ISP cable modem only unit then connect up a separate external connected wifi router system.
