I reply to my own question because I found it difficult to get a clear
answer by searching the web. Perhaps some other non-experts will
benefit.

The trick was to set up the interface correctly. The term "static" in
the second line is what is critical. My big mistake here was that I
needed to change wireless-mode from managed to ad-hoc. As long as the
mode is managed, wicd-gtk had to be started to gain access to the
network.  Also mandatory it seems is the address line. All online
discussions presume its presence. The netmask line is usually
recommended as well, but I didn't check to see if it is mandatory in my
case. In some cases, a channel line is apparently needed. Often the
gateway line is left out, but in my case it was mandatory (here I had
forgotten that my new router's address is 192.168.1.254).

It seems that what lines are needed depends to a degree on the
situation, which is probably why online discussion is a bit
inconsistent. Using a static address obviously suits a work station in a
fixed location. On my machine it greatly sped up boot time.

moving wireless to static IP address

2016-06-13 Thread Haines Brown 
To avoid booting delay while DHCP tries to get an IP address, I decided
to use a static address for the wlan0 interface.

I tried this:

auto wlan0
iface wlan0 inet static
  address 192.168.1.124
  gateway 192.168.1.1
  netmask 255.255.255.0
  wireless-mode managed
  wpa-ssid XXX
  wap-psk XXX

This produces the error: Failed to bring up wlan0. The IP address is
what wlan0 was given before by DHCP, although it seems sometimes a
different address was assigned. In any case, neither work.

Should I also have done something with my router? I don't want to upset
the dynamic assignment for other machines and disks.

The wicd Preferences I also set up for static IP address. However, the
check box before the Key field is not checked, for apparently it wasn't
necessary.
