Losing WiFi every 15 minutes and it's unsecured
My modem Xfinity gateway is losing the WiFi broadcast every 15 minutes. It's gone for about a minute then back up. I can tell by the front panel lights that are blinking then turn off when I lose the WiFi. (Both channels).
When the WiFi is up, it is unsecured - open connection. I have verified passwords and security are on the channels throught the Gateway interface. I restarted the Gatway several times and even restarted just WiFi module from within the gateway with no change.
Any idea for configuring or need new modem?
