I've just changed ISP and I can't get the changed configuration to stick.
I'm using 'static IP address - manual assignment' from Network

I need to change my address from 192.168.1.0/24 to 192.168.20.1/24.
using iproute2 tools as per wiki I can get everything working UNTIL I
reboot, at which time some of the settings show the old values and others
the new.
I've been manually configuring these settings without problems since I
started using linux in 1994.
I assume that (as well as changing ISPs) you have changed your router and
it has a different internal range to the old one.
Correct
If you have an IP address automatically after booting then something is
bringing up the network automatically. Assuming your Arch install is newer
than 2013 then I would expect you've configured netctl to manage the
interface.
About april 2013
, can't remember details of what I did then but I would have used what was
most like the the original method.
Look in /etc/netctl
[mick@cave ~]$ ls -aR /etc/netctl
/etc/netctl:
. .. examples hooks interfaces
/etc/netctl/examples:
. ethernet-static tunnel wireless-wpa
.. macvlan-dhcp tuntap wireless-wpa-config
bonding macvlan-static vlan-dhcp wireless-wpa-configsection
bridge mobile_ppp vlan-static wireless-wpa-static
ethernet-custom openvswitch wireless-open
ethernet-dhcp pppoe wireless-wep
/etc/netctl/hooks:
. ..
/etc/netctl/interfaces:
. ..
and
$ systemctl list-unit-files --state=enabled

You are probably using dhcpcd. This is what is installed when initially
setting up the OS. Depending on exactly what settings are being reverted
to default it may be normal behavior. What you need to do is find out
exactly which network manager you are using and exactly what settings
are not sticking across a reboot. The fix is probably not difficult but
need more info to be able to make intelligent suggestions. I had a
problem with dhcpcd reverting my DNS servers to the ISP defaults on
every restart.
