Intermittent/random drops of internet connection: SURFboard SBG6782-AC

Since upgrading to a SURFboard® SBG6782-AC all in one Modem/Wifi/Router combo (I know, bad idea), all the devices on our network are experiencing short and intermittent drops from internet access randomly. The devices remain on the wifi network, but lose their internet connections for a few minutes at a time. This happens multiple times a day. The modem/router stays on and does not power cycle when this happens. On a weird and maybe related side note: the majority of the time when trying to load google.com, do searches on google and opening youtube links all seem to take longer than other web pages, sometimes by several minutes. This happens when using different browsers. I've tried to diagnose the problem and there's just too much information out there for me to zero in on the cause. Here are logs and other info to help:

One thing notable I see in those logs is lots of wifi channel change events due to interference.  It would probably be beneficial to try using the 5.0Ghz network the device supports and/or moving your 2.4Ghz network to channel 6 and see if that helps.

Thanks Chris. I'll give that a try for awhile and see what happens.

To add to what ChrisL said, if you have an Android device you can download a free app from the Play Store called Wifi Analyzer that will let you see all the wifi networks around your home and which channel they are using so you can determine which channel is best for you to use, and which ones to avoid.
