I'm using 'static IP address - manual assignment' from Network configuration wiki page.

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. 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. Look in /etc/netctl and $ systemctl list-unit-files --state=enabled --- mrrob ---

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. --Rich

thank you, I now can make sense of most of what to do. DNS isn't working if I try to go through the new modem but that is an issue with the ISP and configuring the modem once I get the password for the account. On 13 July 2017 at 03:43, Rich wrote:
