[Bug 1867465] Re: Installer disconnects wifi (after choosing download while installing, 3rd party)

The key part of dmesg is:

So when using the default driver, your wlan interface came up as
wlp2s0b1.  After the bcmwl driver has been installed, the interface
comes up instead as wlp2s0.

So this new interface doesn't match the configuration that
NetworkManager was using before, and so you do not automatically
reconnect after disconnect (the disconnect itself is unavoidable when
changing driver).

I think this is probably not sanely fixable, short of imposing some
additional rules to force the network device name to be the same in the
two drivers.

Title:
  Installer disconnects wifi (after choosing download while installing,
  3rd party)

Status in Release Notes for Ubuntu:
  New
Status in ubiquity package in Ubuntu:
  New

Bug description:
  ISO testing 20.04 daily 20200314. On the Live desktop I connect to
  wifi. When I click the install icon, and choose to install 3rd party
  (leaving download while installing checked), the wifi disconnects.

  I rebooted and tried again to make sure it wasn't something random.
  (It happened exactly the same.).

  This is an older Dell E5420 laptop with Broadcom BCM4313 wireless
  card. (Today's Lubuntu had a wifi-related problem too. I couldn't
  connect to wifi upon reboot after install. I had to reboot a 2nd time
  for it to work. I reported that to their Discourse forum, not reported
  as a bug yet.).

  I apologize that I don't know the package or pid to report this for.
