Hi, I am getting this highly recurrent problem in which the network
inadvertently 'disconnects' for a minute or two and then automatically
reconnects. It is so recurrent that it makes browsing and simple tasks
almost impossible. My best guess is that this problem is a bug in the
new NetworkManager, probably a blocking thread while network-manager
performs a routine wifi-scan.

I'm using the r88x2bu network driver from the rtl88x2bu-dkms package for
WiFi.  Here is some information about the network.

$ nmcli c
NAME                UUID                                  TYPE      DEVICE

$ nmcli d

lo               loopback  unmanaged    --
virbr0-nic       tun       unmanaged    --

I have attached the system logs, which have the NetworkManager and
wpa_supplicant logging level set to DEBUG.

I am happy to provide any information necessary to resolve this issue.
Thanks
