Problems with zoom

     Hello.  I having been having an issue with my router since I purchased it.  I don't believe that it's my router, I believe that my settings are not properly done, but I am not sure how to fix it.  First, when I am attending meetings and classes via zoom, zoom keeps telling me that my internet is unstable.  The other parties cannot see my camera or hear me when I talk even though my microphone and camera are turned on and working properly.  Second, I play some mobile games on my phone and at times it says that my connection is unstable.  I have checked my network monitoring over zoom and it says I am using .3 mbps download which seems low.  I have 1gbps internet speeds and I get close to 900 mps on my desktop that is hardwired, I get about 100 mbps on my cell phone, and 350 mbps or better on my laptop which is not hardwired.  I checked my zoom settings and it says that I have 0% packet loss.  I assume this is an issue with the QoS or antibufferbloat, but I don't know what the deal is.  I currently have the QoS set to "When high priority traffic is detected" and I have DumaOS classified games checked.  I have the share excess with all devices box checked and I currently have my laptop set to 20% which allows it 183.49 mbps though I think that only comes in to play if things are being queued but my family never reaches the 1 gbps cap that I have and I don't know what's going on.  Now I did not have this problem with zoom or my phone when I still had the old router before I bought the XR500, however I wanted faster speeds and for the most part I am getting them.  If you could please help me, I would greatly appreciate it.
