I'm having the same problem, i believe the culprit is dhclient, which gets
run automatically by wicd. whenever the dhcp lease expires, dhclient overwrites
/etc/resolv.conf with what it gets from the the dhcp server.
to verify that this is indded your problem, do "ps aux | grep dhclient", you should
an entry pop up, referencing a configuration file for dhclient (on my machine it's
to fix this, you need to edit /etc/wicd/dhclient.conf.template
and add a line like the following:
supersede 18.104.22.168 22.214.171.124;
then restart the wicd service with
sudo service wicd restart
this will instruct dhclient to set resolv.conf to the manually specified servers,
rather then to what your dhcp server (i'm guessing the home router at 192.168.1.1?)
is sending you.
wicd should really handle this for you, but this will solve your problem for now.
seems to solve the issue for me.
