I have an AX3000 router that I recently connected to my ISP (Xfinity) modem/gateway.  The modem/gateway is in bridge mode.  Everything was fine until about a week ago when I started noticing that my wifi connection drops whenever I am on video calls or streaming media.  I've contacted my ISP and they have run test and concluded that there are no issues with the gateway or anything else on there end.  I have tried power cycling the modem as well as the router whenever the issue occurs.  Things will go back to normal for several hours, and then the random disconnections start to occur once again.  Any recommendations?  Are there any settings that I may need to adjust on my router?
