Title:
  Sporadic network disconnect and re-connect during wifi-scan after
  upgrading from Ubuntu 18.04 to 20.04

Status in network-manager package in Ubuntu:
  Incomplete

Bug description:
  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
  MIT SECURE          8b2ea417-ed65-4e36-a63e-a231344af87a  wifi

  $ 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
