my ignorance is getting in the way.
i'm sure there's some kind of ladder or hierarchy
that, once understood with terminology nailed down,
could help make sense out of diagnosing not only how
come the <BADWORD> wifi isn't working but other things
the specific problem is to get wifi working on a
dell inspiron 1545 that's got a broadcom 43xx chipset
and on which we've installed ubuntu 9.04.
i'm looking for a general mental model that uses
standard terminology for the pieces that play togethers.
my current impression is the cast of characters includes:
network manager (ubuntu)
wep and wap
realtek, atheros, intel, <BADWORD> broadcom
* up at the top are the applications such as browsers
and email clients.
* beneath the apps is the TCP/IP stack.
* below that there's some other stuff
* then there's firmware and drivers ("kernel modules")
* down at the bottom is the chipset.
recently found links:
someone claimed that post 79 had info to get the wifi working,
and it did until the guy who achieved the success left and the
laptop owner rebooted.
