SBG7400AC2 Wi-Fi intermittent internet speed

Modem rebooted the other day due to signal from WOW cable. Have 600mb download on wired, wifi averaging about 10mb. Wasn’t like that before the reboot. Also now can’t go further than 10’ away before signal drops. Am I missing a setting somewhere? Thoughts?.

Since this happening on Wi-Fi we would suggest you to try changing Wi-Fi channels  will avoid interference and that will give better speed and connection. If other Wi-Fi sources such as neighboring wireless access points are using the same wireless channel, this may cause intermittent connectivity issues, even if the competing signal is relatively weak. 
Changing the wireless channel within the  gateway can improve connectivity and speed.

After changing Wi-Fi channel as recommended on the link restart the modem then we would request you to monitor the connection for next 24hrs.
