Such settings can disappear if your dial-up/ISP-connect scripts rewrite
your resolv.conf file with name server addresses discovered from your
ISP.

If so, and you never want to use their's, you can configure your dial-up
script not to update the resolf.conf file.  I seem to remember that the
wvdial man file(s) detailed how to do that.
