Re: Multiple Wireless Interfaces

["Harrison Metzger" <harrisonmetz gmail com>]

Dan,

Thanks for your reply. In Fedora/sugar the mesh and wireless work fine. I forgot to mention that I have installed Debian and am using that. In general, if a computer has 2 wireless adaptors, is there a way to tell nm which one to use. (Or if not, in Linux, how can an adaptor be disabled so nm won't attempt to use it?)

You can click the appropriate circle in the Mesh View, either click an
existing AP, or click a circle for Mesh 1/6/11.  NetworkManager will, by
default, look through all mesh channels first for a school server, after
which it will fall back to an AP you've previously connected to.  If
none of those are found, it will try an XO-as-Mesh-Portal on each mesh
channel, then finally fall back to Mesh Channel 1 in a peer-to-peer mesh
situation.

You should definitely see wireless access points in Mesh View though
after it's booted up.

What build # are you running, and can you report the output of, from a
root terminal, '/sbin/iwlist eth0 scan' ?
