Hello, I check the log, there are two questions?
1. have you tried to disable ufw? does it help? 2. did you run iperf test to check the wireless throughput? I found there is a Wi-Fi firmware crash inside the log, but I am not sure if it is the root cause, Generally, the driver should have recovery mechanism after the micorcode crash. There is a newer iwlwifi- QuZ-a0-hr-b0-59.ucode firmware in https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/linux- firmware.git/, would you mind to have it a try?

Sometimes, email cannot be retrieved / computer complains the connection was momentarily lost. - If I am on a wire, this problem does NOT occur. - This problems occurs on wireless independent of the platform used (behavior seen in both Google Hangout and Zoom) - This problem does NOT occur on Windows. I did a meeting where both my Linux and Windows machines were connected to the same meeting and using the same wifi router, and while the performance on Windows was flawless, unfortunately it was not so on the Ubuntu box. So I don't think my wifi router or network is to blame. - As far as I can recall, the problem used not to be there 2 weeks ago. So it may have been introduced by a recent update. - As communicated before, I am on a certified machine from Dell, recently purchased with Ubuntu already on board from factory (I assume the logs there were sent to you would contain the information). - I tried to generate a log on the wireless, but the process did not let me do this very easily. I am more than happy to send you additional information - but please let me know which package you want me to spy upon exactly, as I am not sure what would be helpful in this matter.
