Frequent disconnects

Just upgraded to the RBK853 and I’m having a terrible time with random disconnects. The WiFi is staying connected, but internet connection drops. Have to disable and re-enable wifi again. Does it every few minutes. Have tried changing the coexistence setting, etc. When I got home, I actually couldn’t even get connected to my wifi network and had to reset to defaults. Now it’s working but was a pain to set up. Had to setup via browser because the app wasn’t detecting that I had internet service. I previously had the AC3000 and didn’t have any issues.
