I'd like to use the Net connections one at a time.
But I'm not yet sure when I'd have a wifi connection.
Windows programs I've used with wifi have places to
view the wifi's within range, whether they are open, encrypted and
signal strength.
But I think I need to set the box's IF's and networks first.
Thanks for the info on NetworkManager. I just figured out
that the gui with settings I've been using, and the service
daemon are the same program ( I think ???) .. I hadn't thought
about both at the same time.
I didn't know about the static IP, and scripts with S-C-N,
although I'd set some settings in the config file for wvdial,
and perhaps once for eth: by that I mean I explicitly edited
the config file.
If someone could confirm that NetworkManager can be used
to setup a serial 56k dialup, I'd appreciate it. I don't want to
spend hours screwing mine up only to find it can't be done.
I DO see it will do dsl with several ppp types of connections.
I don't see a "normal" ppp, nor check for Modem commands, or
serial port.
The S-C-N menu's for a modem setup can easily mention IP address
in 3 different places, and Gateway in 2 different places. So I'm
confused about which is IF address, or Destination address, or if an
IF route is the internal route to the IF, or the route externally to
the IF etc....and is the gateway the host 127.0.0.1 gateway or if IF
IP is the gateway... etc .. I"ve gotten it right before, but I've
regressed recently.
I'm not comfortable about the interaction between S-C-N and MN.
While the S-C-N may be scripts, there is still the setup menus that
edit the config data file.
I think the final steps of setting up the ASUS and switching the ASUS
cable from LAN to WAN should be challenging..but I'm not there yet.
thanks for the help you've given!!
