[PLUG] ER-X: change login, save, reboot, cannot connect

First, restore the config I sent you.

You'll need to restart your network, since you'll get a 192.168.55.x
address after the ERX restarts.

Read this: https://dl.ubnt.com/guides/edgemax/EdgeOS_UG.pdf

In particular, see Chapter 10 which covers users.
I'm not sure where you'd set a hostname for the router. I am also not clear
why you'd need that. If you want to create a local DNS mapping between
names and your local IP address, look in Chapter 7 under the section
labelled DNS.

Chapter 12 covers Wizards. Turns out Tomas and I guessed wrong about the
wizard names:

"There are two SOHO deployment setup wizards available:• WAN+2LAN The WAN+2LAN
setup wizard is the most basic version available. The WAN port is eth1. Go
to the WAN+2LAN Wizard section below.• WAN+2LAN2 The WAN+2LAN2 setup wizard
allows you to bridge the LAN interfaces and/or change the subnets configured
on the LAN interfaces. The WAN port is eth0. You can also configure user
accounts during setup."

In addition, at the beginning of each wizard description, the manual says
(varying slightly by wizard):

"You can still use the WAN+2LAN setup wizard even if the EdgeRouter is
already configured. The WAN+2LAN setup wizard ***will replace the entire
configuration*** and require a reboot when the new configuration is
applied." (emphasis added).

If you were starting from scratch, the "Basic Setup" (which is the same as
WAN+2LAN2), would be the thing to use, but not if you wanted to keep
anything already configured on the device. Furthermore, I'm pretty sure
restoring a configuration also completely obliterates what was there before.

If you restore my config, you can ignore the wizards completely.
