Re: NetworkManager: how to select wireless interface

I just would like to know if it is possible to choose which interface to

Equally at some point no doubt someone will want to have NM able to connect
to either a wire or a wireless interface - and then it should be part of
normal operation to be able to select wired or wireless.

One reason some people don't use NM is because it seems not obvious that
NM can actually do this. If it can the documentation should be easily available
so that users can get at it easily.

NM has been around since FC6, people have had these complaints since FC6, nothing has gotten better since FC6. Actually, since some system-config tools have been removed, things have gotten worse. There is no good documentation, there is only a raft of incomplete and in some cases contradictory documents from various uncoordinated sources.

If you have anything as simple as a laptop with both cable and wireless NIC, good luck trying to define which to use where. If you add a modem, there seems to be some path by which NM will try to use it for PPP. And if you have multiple wireless networks available, I have no idea how NM picks which to use other that "not the same one in a deterministic manner."

What is needed is named configurations, which allow you to specify exactly what each NIC will do, masks, etc. Also WEP/WSA settings, not trying DHCP before WSA, only trying DHCP when to to, using static IP addresses.

I've given up on point-to-point, the whole concept is ignored.

NM seems to make the assumption that the user is a moron, and NM must make the decisions and not let the user change them. Either that or it assumes that the user has read the developer's mind and knows voodoo to make NM do anything beyond the simplest configuration.
