Re: Selecting among multiple WAPs with the same SSID (again)

[Derek Atkins <warlord MIT EDU>]

In general sites shouldn't use the same ESSID for b and b/g APs.
They MAY for b/g vs. a (as those are truly different networks),
but b and g are effectively the same.  You should talk to your
provider and complain to them.  Or at least I would.

My personal opinion is that NM should  have a setting (by ESSID)
about whether to autoroam or not.  If autoroam is on then NM should
automatically roam across all BSSIDs in an ESSID using 802.11 handoff.
It should let you choose the ESSID based on the 802.11 type (a or b/g).
If autoroam is off then it should let you choose the BSSID and it will
stay there until you go out of range or manually disconnect.

I don't know if this is how they plan to do it, but this is how I imagine
it SHOULD work.
