I found the issue. Windows Explorer only had visibility of the 'boot' volume and that was all I was wiping. I used Computer Management to delete all the volumes on the SD card.

That's still not worked! It keeps booting with the previous configuration even though I've completely deleted all the volumes and formatted.
Make sure you're telling your SSH client to log in to the Pi as root. If you use a different user name, you will be asked for a password. (This is a security measure so the ssh server does not confirm or deny that a user exists. Logging in as other than root is actually impossible since no other users are defined).
The Pi4 is included in 21.02 so you could consider using what is now the 21.02-rc2 build instead of snapshot. Release builds include LuCI.
That's not the problem I'm experiencing. I am formatting the SD card, but the old configuration is still present when I reinsert the SD card and boot the Raspberry Pi.
It seems the old file structure and configuration files are surviving the formatting process.
I am currently wiping the SD Card by writing zeros to the entire device in an attempt to resolve the issue. It's a 16GB card, so it's taking a while.
Properly writing the "factory" image to the card, starting at the first sector, will clobber any existing partition table (disk label) and make any previous data stored on the card moot. There is no need to format or zero the card first.
I'd like to use a USB3.0 to Gigabit ethernet dongle for my WAN connection. It is an ASIX model and I am aware that it will max out at 600Mbps. My WAN is 80/20 FTTC ADSL, so that shouldn't be an issue.
I can see there is a package for my particular device.
I have attempted to install it via the following command:
